Prompt library

59 prompts, ready to paste

These are copy-paste prompts for an AI assistant connected to JustOnce. Paste one into Claude, ChatGPT or Cursor and it works as written — no setup, no placeholders to decode. Many come in pairs: one teaches your memory something, and the other gets it back days later in a completely different tool.

Getting started

Fifteen minutes that make every prompt after this one shorter. Start here even if you skip everything else.

See what it already knows about you

Fetches the core profile your assistant loads at the start of a session — the verified and high-confidence facts — so you can read it rather than guess at it.

Pull up my standing profile from JustOnce and show me exactly what you know about me. Then tell me what is obviously missing.

The five-minute brain dump

Bulk-loads your starting context in one go — up to 50 memories per call — each one classified and entity-extracted as it lands.

I am going to paste a brain dump about my work and my life. Save each distinct fact to JustOnce as its own memory, keep my wording, and tell me how many you saved. Ask me about anything too vague to stand on its own.

[PASTE 10-20 LINES: your role, the people you work with, the projects you are running, the tools you use, how you like things done]

Teach it how you want to be written to

Stores your writing rules as durable memories, so the next assistant reads them out of your vault instead of you retyping them.

Save this to JustOnce as a standing preference: when you draft anything for me — email, docs, posts — use Australian English, short sentences and no exclamation marks. Never open an email with "I hope this finds you well". No bullet points unless I ask for them.

Pairs with Draft in your voice from a cold start

Draft in your voice from a cold start

Recalls the preferences you saved in a different tool, days earlier. The "show me the rules" line is there so you can see recall actually fired.

Check JustOnce for how I like things written, and show me the rules you found before you draft anything. Then reply to this email in exactly that style.

[PASTE THE EMAIL]

Move in from another AI’s saved memories

Bulk-imports the memory you have already built up somewhere with a cap, 50 at a time, into a store that does not quietly drop the oldest entries.

Here are the saved memories from my other AI tool. Load all of them into JustOnce, one memory each, keeping the original wording. Skip anything that is already out of date and tell me what you skipped.

[PASTE YOUR SAVED MEMORIES LIST]

Set the rule for what gets saved from now on

Writes your capture rule into the vault itself. Be clear-eyed about what that is: an instruction your assistant reads and follows, not a server-side filter.

From now on, save durable facts about my work to JustOnce as we go — decisions, preferences, people, deadlines — without stopping to ask me each time. Do not save anything about my health or my family. Never save passwords, API keys or card numbers. Save that instruction to JustOnce too, so it outlives this chat.

Work, clients and accounts

The account history a handover usually loses. Recall, not capture — nothing listens to your calls or your CRM.

Teach it your whole client roster

business

Loads the whole book at once, up to 50 per call, with each client extracted as an entity you can ask about later.

Save each of these to JustOnce as a separate memory — one per client — keeping my wording: who they are, my day-to-day contact, what we actually do for them, what they are sensitive about, and the billing arrangement.

[PASTE ONE LINE PER CLIENT]

Pairs with Walk into a client call with the whole history

Walk into a client call with the whole history

business

Builds a brief for that account out of your own memories. The "say so" instruction is the bit that stops an assistant inventing an account history.

I have a call with [CLIENT] in ten minutes. Pull everything JustOnce has on them — the contact, what we have delivered, what was promised, what they are touchy about — and give me a one-page brief. If something is missing, say so rather than filling the gap.

Record what you actually promised

business

Keeps the commitment verbatim alongside the distilled version, so the exact sentence survives — not somebody’s paraphrase of it.

Save this to JustOnce word for word: on today’s call with [CLIENT] I committed to [WHAT], by [DATE], and I said [SCOPE OR PRICE] was included. [WHO ELSE] was on the call.

Pairs with Check the exact words before you contradict them

Check the exact words before you contradict them

business

Returns the original text stored on each memory — the thing you need when a customer says "we were told X would be included".

What have we committed to [CLIENT]? Give me the raw wording of each commitment and the date it was made, not a summary.

Log the account the moment the call ends

business

Turns a two-minute post-call dump into structured account memory. Nothing is captured automatically — this is you telling your assistant, once.

Save these to JustOnce as separate memories about [ACCOUNT], in my words: who was on the call, what they said their priority is now, the risk they raised, the number they quoted, and the thing they are unhappy about.

Pairs with Turn QBR prep into "what changed"

Turn QBR prep into "what changed"

business

Reconstructs the account as it stood at a date, then diffs it — so prep starts from what changed instead of rebuilding the account from scratch.

Show me what JustOnce had on [ACCOUNT] as of [DATE OF THE LAST QBR], then everything saved about them since. I want the delta, not the whole story.

Map who is who inside an account

business

Extracts each person and company as an entity and records the relationships between them, which is what makes the next prompt possible.

Save these to JustOnce as separate memories: at [COMPANY], [NAME] is [ROLE] and is the one who signs. [NAME] is [ROLE] and is our champion. [NAME] blocked the last renewal because [REASON]. [NAME] came over from [PREVIOUS COMPANY].

Pairs with Ask who else you already know at a company

Ask who else you already know at a company

business

Walks the entity graph outwards from a company, surfacing connections you never wrote down as a single fact.

Start from [COMPANY] and show me everyone and everything in my vault connected to them, two levels out — people, projects, other companies. Then tell me which of those people I have actually spoken to.

Stop the team re-deciding the same thing

business

Creates the space, shares those memories in, and sends the invitation. Two honest caveats: the person must already have a justonce.ai account, and they read the space in the web app — memories another member shares in do not come back in your assistant’s search yet.

Create a shared space called "[TEAM] — decisions" and add every memory I have about decisions we have made and why, including the approaches we tried and rejected. Then invite [EMAIL].

Documents and files

The web uploader takes .txt, .md and .csv. Everything else — PDFs, spreadsheets, photos — goes in through your assistant, which reads the file and saves what matters.

Get a PDF in without uploading anything

Your assistant reads the file and writes the memories; JustOnce stores them and keeps the original attached. We run no OCR of our own — the reading is done by the model you are already talking to.

Read the attached PDF, then save the key points to JustOnce as separate memories — the parties, the dates, the dollar amounts, the notice period, and anything I would be annoyed to have forgotten. Keep the original file attached to the memory.

Pairs with Find the clause without opening the file

Find the clause without opening the file

Finds the memories the document produced, then points back at the file they came from — documents are recalled through their memories, not by scanning the stored file.

What does JustOnce have on my [CONTRACT]? I need the notice period and the renewal date, and tell me which document it came from.

Keep the policy where you will actually find it

Stores the details as memories and retains the actual document against them, so the file is still there in a year when you need it.

Save this to JustOnce: our [home and contents / car / health] insurance is with [INSURER], policy number [NUMBER], excess [AMOUNT], claims line [PHONE], renews [DATE]. Attach the policy PDF I am sending and keep the original.

Pairs with Make a claim at eleven on a Sunday night

Make a claim at eleven on a Sunday night

personal

Recalls the details and fetches the stored PDF back into the chat over the authenticated connection — no download link, no shared folder.

A pipe has burst. What does my home and contents policy cover, what is the excess, what is the claims number, and pull up the policy document so I can read the exclusions.

Keep the receipt, not just the number

Your assistant transcribes the image and JustOnce keeps both the facts and the picture. Again: the model does the reading, we do the remembering.

Here is a photo of the invoice. Read it and save the supplier, the amount, the invoice number, what it was for and the due date to JustOnce as one memory. Attach the image to it.

Email forwarding

Forward it once and it is memory. Needs a paid plan and your own provider key — the mail is read by your model, so it never touches your JustOnce allowance.

Get your forwarding address and start using it

Your real address is in Settings — "vault-" plus 16 characters, unique to you. It is the credential, so treat it like one. Forward a confirmation, an invoice or a whole thread to it and the body is stored word for word, then distilled into memories. Requires a paid plan and a connected Anthropic, OpenAI or Google key.

vault-[YOUR 16 CHARACTERS]@ingest.justonce.ai

Pairs with Ask what you booked, months later

Ask what you booked, months later

personal

Recalls everything those forwarded confirmations became, months after you forwarded them and forgot about them.

I fly to [CITY] on [DATE]. What have I got booked — flights, hotel, car, confirmation numbers — and what is still not sorted?

Reconcile a job from the invoices you forwarded

business

Searches the memories your forwarded invoices produced and lets the assistant do the arithmetic. The duplicate-spotting is your assistant reading the results, not a feature watching your invoices.

Find every supplier invoice in JustOnce connected to [JOB OR PROJECT] and give me a table: supplier, invoice number, amount, date, what it was for. Total it, and point out anything that looks like it was billed twice.

Turn a forwarded thread into a decision record

business

Reads back the memories the thread produced and writes one distilled decision alongside them. The original text stays exactly as it arrived.

I forwarded the "[SUBJECT]" email thread to JustOnce this morning. Read what came out of it, work out what was actually decided, and save that as one clear memory in plain language so I never have to re-read the thread.

Fetch the attachment, not just the email

Every attachment on a forwarded email is kept as a linked document — up to ten per email — so your assistant can pull the actual file back later.

Pull up the attachment that came in with the email I forwarded from [SENDER] about [SUBJECT], and read me [THE SECTION YOU WANT].

Developers and coding assistants

Your stack, your conventions, and the reasons behind old decisions — recalled by whichever coding assistant you happen to be using today.

Teach it your stack once

business

One bulk write that every coding assistant you connect afterwards can read.

Save each of these to JustOnce as its own memory about how I build: the language and framework versions I am on, my package manager, my test runner, how I name branches and commits, the linter rules I care about, and the two libraries I refuse to use.

[PASTE YOUR ANSWERS]

Pairs with Start a new repo with your conventions already in place

Start a new repo with your conventions already in place

business

Pulls the conventions you taught a different tool, in a different week, into a brand new project. Tell Claude on Monday; Cursor knows it on Thursday.

Before you write a line, check JustOnce for my stack and my coding conventions and list what you found. Then scaffold [WHAT YOU WANT] following them exactly.

Stop your CLAUDE.md from rotting

business

Moves the half of your context file that is about you into a store that does not grow until the model starts ignoring it.

Read the CLAUDE.md in this repo. For every rule in it that is really a durable fact about how I work — rather than something specific to this codebase — save it to JustOnce as its own memory. Then list what you saved and what you left in the file.

Record the decision, and the reason

business

Records the rationale, not just the outcome — the part that has evaporated six months later when someone asks why.

Save this to JustOnce in my words: on [PROJECT] we chose [OPTION A] over [OPTION B] because [REASON]. We will revisit it if [CONDITION] changes. [WHO] disagreed, because [WHY].

Pairs with Ask why past-you did that

Ask why past-you did that

business

Returns the original rationale plus its history, so a decision that was later changed shows you both the current answer and the one it replaced.

Why did we go with [CHOICE] on [PROJECT]? Give me the reason recorded at the time, not your best guess, and tell me whether it has since been superseded.

Save the traps so you only hit them once

business

Turns an hour you have already lost into an hour nobody loses again — including future you, on a different machine.

Save each of these to JustOnce so any assistant I use hits them once instead of every time: [THE PORT THAT IS ALWAYS TAKEN], [THE ENV VAR NOBODY DOCUMENTS], [THE COMMAND THAT NEEDS SUDO], [THE TEST THAT IS ALWAYS FLAKY], [THE THING THAT LOOKS BROKEN AND IS NOT].

Pairs with Ask before you burn an hour on a known trap

Ask before you burn an hour on a known trap

business

One recall at the top of a session that stops an assistant rediscovering a problem you solved in March.

Before you start debugging, check JustOnce for anything I have recorded about this project’s environment and its known traps, and tell me what you found.

Time travel and corrections

Corrections supersede rather than overwrite, so the old answer is still there when you need to know what you believed at the time.

Correct a fact without erasing the history

Supersedes the old value. Nothing is deleted — the previous answer stays in the history, with the dates it was true.

Update JustOnce: I am not at [OLD COMPANY] any more. I started at [NEW COMPANY] on [DATE] as [ROLE]. Correct the existing fact rather than adding a second one next to it.

Pairs with Ask what the answer was back then

Ask what the answer was back then

Answers from the value that was valid on that date — what you need when you are reconstructing an old invoice, a tax year or a contract.

As of [DATE], what did JustOnce have on file for my [job / address / rate / stack]? I want what was true then, not what is true now.

See every value a fact has ever held

Returns the whole chain of values for one fact, with dates. Nothing had to be overwritten to get there.

Show me the full history of what I have told you about my [rate / job title / address] — every version, when each one was true, and when it changed.

Log the rate you agreed, with the date it starts

business

Records the new rate as a correction with a start date, so both numbers stay queryable instead of one replacing the other.

Save to JustOnce: from [DATE] my rate for [CLIENT OR WORK TYPE] is [AMOUNT], up from [OLD AMOUNT]. Keep the old rate in the history — I still invoice against it for work done before that date.

Pairs with See every value a fact has ever held

Retire something that is no longer true

A soft, reversible invalidation. It stops coming back in recall, and you can bring it back if you were wrong.

I have cancelled the [SERVICE] subscription. Mark what JustOnce knows about it as no longer current, but do not delete it — I want the history.

Rebuild a project as it stood at a deadline

business

Two questions in one: the state at a date, and the delta. Useful when the argument is about what was agreed before the change.

Reconstruct what we knew about [PROJECT] as of [DATE] — the scope, the budget, who was on it, what had been agreed — then tell me what has changed since.

Home and life admin

The paperwork that currently lives in one person in the household’s head.

Teach it the house

personal

One bulk write, and the household admin stops living in one person’s head.

Save each of these to JustOnce as its own memory: our electricity retailer, plan and account number; the gas one; the internet plan and when the contract ends; the council rates reference; the water account; and who the strata or body corporate manager is.

[PASTE YOUR DETAILS]

Pairs with Sort out a bill that looks wrong

Sort out a bill that looks wrong

personal

Everything you need to make the phone call, without the drawer, the shoebox, or the other person in the house.

[UTILITY] has billed us [AMOUNT] and it looks wrong. What does JustOnce have on that account — the plan, the rate, the account number, when the contract ends — and what should I be asking them?

Never lose the good tradie again

personal

The verdict is the part everybody forgets to write down, and the only part that matters in two years.

Save to JustOnce: our [TRADE] is [NAME] at [BUSINESS], [PHONE]. Used them on [DATE] for [JOB], charged [AMOUNT]. [WHAT I THOUGHT OF THEM]. I [WOULD / WOULD NOT] use them again.

Pairs with Get the good plumber back

Get the good plumber back

personal

The two-year-old recommendation you would otherwise be asking a group chat for.

Who did we use for [THE JOB] last time, what did they charge, and did I say I would use them again? Give me the number.

The car, the rego and what the mechanic said

personal

Registration, insurance and service history as facts, so the next booking starts from what the mechanic actually told you.

Save these to JustOnce: our car is a [YEAR MAKE MODEL], rego [PLATE] due [DATE], insured with [INSURER], policy [NUMBER]. Last serviced [DATE] at [KILOMETRES] by [MECHANIC], and they said [WHAT NEEDS DOING NEXT TIME].

Pairs with Ask what the mechanic said last time

Ask what the mechanic said last time

personal

Turns "something about the brakes, I think" back into the thing they actually said.

I am booking the car in. What did the mechanic say needed doing at the last service, what was the reading on the odometer, and when are the rego and the insurance due?

Set the house-sitter up with exactly what they need

personal

One space with the slice they need and nothing else. They read it in the JustOnce web app and need an account of their own; close the space when they are done and that access ends.

Create a shared space called "House sitting — [DATES]" and add what you know about the bins, how the alarm works, the vet and emergency contacts, the pet feeding routine, and which neighbour has the spare key. Then invite [EMAIL].

Research and learning

What you worked out, why you believed it, and where it came from — kept past the point where you close the tab.

Keep what you worked out, not the tab you closed

Distils a long session down to the few facts that will still matter next month.

Save what we just worked out to JustOnce as two or three separate memories in my words: the conclusion, the reason behind it, and the source. Do not save the whole conversation.

Pairs with Pick up a thread you dropped three weeks ago

Pick up a thread you dropped three weeks ago

Returns a pre-formatted context block for that topic, so a new chat in a new tool starts where the last one stopped.

Give me everything JustOnce has on [TOPIC] — what I concluded, what I had not resolved, and where it came from. Then tell me the next question I should be asking.

Ask what you already think about something

Your assistant does the comparing — JustOnce does not flag contradictions for you — but the dated history is what makes the comparison possible at all.

Before you answer, check JustOnce for what I have already concluded about [TOPIC]. If I have said two contradictory things, show me both with their dates and let me decide which one still stands.

Turn a course into memory instead of notes

Builds a record of what you know, rather than a folder of notes you are never going to reopen.

I am working through [COURSE OR BOOK]. At the end of each session, save what I actually understood to JustOnce as separate memories in my own words, and tell me plainly which parts I clearly have not got yet.

Auditing what it knows

The whole point of an inspectable memory is that you can go and inspect it.

Ask it what it thinks it knows

The five-second audit. If a category has grown in a way you did not expect, you can go and look at it.

List every category in my JustOnce vault with how many memories are in each, then show me the ten most recent things you saved about me.

Check how sure it is before you rely on it

Recall returns a confidence tier per memory — verified is 0.90 and up, high confidence 0.70 to 0.89 — so you can hold a form-filling assistant to the reliable ones.

Look up what JustOnce has for my [current employer / address / rate] and tell me the confidence tier on each one. I only want to act on the ones marked verified or high confidence.

Read it back and correct what is wrong

A supervised clean-up pass. Corrections supersede and retirements are reversible, so nothing you do here is destructive.

Search JustOnce for everything about [PERSON, PROJECT OR COMPANY] and read them back to me one at a time. I will tell you which ones to correct and which to retire.

See what it has linked to what

Walks the entity graph so you can see the inferences, not just the facts. Worth doing once, because this is the part of a memory layer people most expect to be a black box.

Start from [PERSON OR COMPANY] and show me everything in my vault connected to them two levels out — people, projects, organisations — and tell me how it made each connection.

Prove it is quoting you, not paraphrasing you

Every memory keeps your exact wording alongside the distilled version. The tool name is self-reported by whichever client wrote it, so read it as a label rather than as proof.

Pull up the memory about [THING] and show me the raw version — my original words, not the summary — plus when it was saved and which tool saved it.

They only work once something’s connected

One endpoint, OAuth sign-in, no API key. About a minute for Claude, ChatGPT, Cursor, VS Code, Windsurf or Gemini.
