Tell your AI thingsjust once
Every answer lives somewhere else: an email, a document, a notebook, your head. Life should not be this hard, at home or at work. JustOnce is one simple place for it, and makes the AI you already use your superpower. Save it once, ask when it matters, and on Plus your partner or team can ask too. Take back control.
Connect once. Save. Then ask.
You add JustOnce to the AI you already use, once, on a computer. From then on you save things as they come up, by telling it or handing it a document or photo, and ask for them when they matter.
Save it once
Say it mid-chat, type a note, hand your AI the PDF, or forward the email on a paid plan. The policy number, the dates, the photo of the serial plate.
It keeps it, as you said it
Your exact words, the original attached, every change dated, so “what was my address last year?” still has an answer. Encrypted before it is written.
Then just ask
Ask ChatGPT or Claude “what’s my excess?” or “what did I quote Harborview in April?” and it answers from what you saved. From a space you share on Plus, your partner or team can ask their own AI too.
You, on a day like this.
Illustrative moments. In each one you saved something once, then asked the AI you already use, and it answered from what you saved. The shared one names who saved it, because that is what the other person's assistant shows.
Out of your inbox, Downloads and camera roll.
Into one place your AI reads. Typing into a chat box is only one of four ways in.
Just say it
Mid-chat: “remember that Dave from Northside Plumbing did the hot water in May.” Next month ask “who did the hot water?” and it answers, in your words, with the date.
Claude · ChatGPT · Cursor · any MCP client
Give it your documents
Hand your AI the insurance PDF once. It saves the policy number, excess and renewal date, keeps the original attached through a one-time link, and answers “what’s my excess?” next year. Text files can go straight into the web app.

Forward the email
Every paid account gets a private forwarding address. Send a receipt, a policy or a booking confirmation and it becomes memories, with the attachments kept as documents.
Paid plans · runs on your own AI key, so it never touches your allowance
Share it with someone
Photograph the policy once and share it into a household space. Your partner asks their own assistant — Claude, ChatGPT, whichever — and it answers from what you shared, attributed to you. Your own vault stays private.

How sharing worksPhotograph it and it's filed
That second route is at its best with the camera you already have out. Snap the serial plate, the loyalty card, the screen you will never find again — then send the picture to a connected assistant.
JustOnce runs no OCR of its own, and that is deliberate: the model you are already talking to does the reading, then writes the facts in as a memory and hands you a one-time link to attach the original photo as a document.
Share that memory into a household space and the photo goes with it. The other person asks their own assistant — years later, in a different tool — and gets the answer attributed to you, with the picture a question away.
Save this one to JustOnce and put it in the Smith household space.

Tap to attach the photo — the link works once and expires in 15 minutes.
The dishwasher just died. Is it still under warranty, and what model is it?
NW-DW600, serial 4417-88203. The warranty runs to March 2031, so yes. The photo of the plate is in the Smith household space if you need it.

Illustrative example. Claude reads the photo, JustOnce keeps the facts and the original, and the other person's own assistant answers from the shared space.
Give your AI a memory that never forgets what you give it
Add JustOnce to Claude, ChatGPT or any assistant that supports connectors. What you save, it can answer from in every conversation after that: the policy, the quote, the decision, the date.
See it in action
Once connected, your AI assistant can search your memories, add new ones, and explore your personal knowledge graph — all within a natural conversation.
I need to book flights to Melbourne next week. What do you know about my travel preferences?
Based on your stored preferences, I can see:
- -You prefer window seats on flights
- -Your Qantas Frequent Flyer number is on file
- -You're vegetarian (meal preference stored)
- -Last Melbourne trip was March 2026, you stayed at the Crown Metropol
Want me to help book with these preferences?
Illustrative example. The tool calls are real; the memories are not anyone's.

Step-by-step setup for every tool21 tools your AI can call
Your assistant can search your vault and your shared spaces, store, correct, time-travel, read documents and open new shared spaces — 21 tools over one MCP endpoint. Nine of the most-used are below.
Time-Travel Recall
get_as_ofAsk what was true as of any date. Bitemporal memory keeps full history — your AI answers with the then-valid fact, not just the latest one.
Search Memories
search_memoriesSemantic search across your vault — and what others have shared with you, attributed to whoever shared it. Your AI asks "What's their flight preference?" and gets the answer instantly.
Add Memory
add_memoryStore new information directly from conversations. Tell Claude your new address once — it's remembered forever.
Get Context
get_contextYour AI retrieves relevant background before responding. It knows your dietary requirements, travel preferences, and health details.
Walk Your Graph
get_relationshipsRead or walk your personal knowledge graph. Discover how people, organisations, and details relate to each other.
Load Your Profile
get_core_profileEvery session starts with your standing profile and a map of all 18 categories, across life and work, so your AI knows what you've stored and where.
Find Related Entities
find_related_entitiesDiscover all the people, places, organisations, and concepts extracted from your memories.
Store Document
store_documentKeep the original file — a PDF, a photo of a rating plate, a Word or Excel document — encrypted against the memory your AI wrote from it, and fetch it back later over the same connection.
Open Shared Space
open_shared_spaceCreate a space for your household, a client or a project and share memories into it — the documents attached to them go too. Each member's own assistant recalls what was shared, attributed to the sharer.
Your account, your agents
Every MCP connection is OAuth-authorised to your account — the agents you connect see only what your account can see, memories you share reach only the members of that space, and nothing you store is used to train models.
Works with Claude Desktop, Claude Code, ChatGPT, Cursor, VS Code, Windsurf, Gemini, and any MCP-compatible agent.
Ask what was true last March
Most memory tools keep the latest value and quietly discard the past. JustOnce is bitemporal: every fact keeps its full history, so your AI can answer with what was true then — not just what is true now.
Ask what your address was last March. It answers with what was true then. Facts are stored verbatim-first — your exact words, never a lossy paraphrase — and every answer carries a confidence tier, so your AI knows a verified fact from a guess.
What was my address as of June 1st?
As of June 1st you lived at 4 Kent St — you moved to 12 Harbour St on June 23rd.
VerifiedFactIllustrative example. get_as_of is a real MCP tool.
A memory worth trusting
The paperwork, not just the chat
The policy PDF, the lease, the photo of the serial plate. Saved once with the original attached, and answered when you ask “what's my excess?” a year later, in ChatGPT, Claude or Cursor.
Verbatim-first
Your exact words are kept, not a lossy paraphrase. What you said is what it recalls.
Confidence tiers
Every fact is scored, so your AI knows a verified fact from an inference.
Time-travel recall
Bitemporal memory keeps the full history of every fact. Ask what was true as of any date and get the answer that was right then.
get_as_ofEncrypted at rest
Every memory body is sealed with AES-256-GCM before it is written — and never used to train models.
Ask in plain English
Semantic search understands meaning, not keywords — “what's my landlord's number?” just works.
Your life's paperwork too
Passport numbers, insurance policies, frequent-flyer details — filed, searchable, and recallable by your AI.
Every new chat starts from zero.
JustOnce doesn't.
A model has no memory between sessions. When the conversation ends the context window is evicted, and everything you explained is gone — not summarised, not archived, gone. Open a new chat tomorrow and you are a stranger again.
That's why you keep re-explaining yourself — the policy number, the client's terms, your kid's allergy, your address — in every new conversation.
JustOnce was built on a simple premise: you should only need to say something once. Your memory persists so neither of you has to.

Once. That's how many times you should have to say it.
Why “justonce”?
Because you should only need to say a thing once. Not once per tool, not once per conversation, not once per week. Just once. Your AI handles the rest.
Your privacy, engineered
Every memory body is sealed with AES-256-GCM — an authenticated cipher — before it is written to storage, under a key issued for its space. Documents you upload are encrypted the same way under your own key, and the memory engine itself runs on a private network with no public address.
Your memories are never used to train models, and every memory we hold is one you can see, correct, or remove.

Frequently asked questions
What is justonce.ai?
A place for the details and documents you keep digging for, so ChatGPT or Claude can answer from them: the policy number, the lease dates, your kid’s allergy, a client’s brief. Save each once, in your own words, with the original attached. Share a space with your partner or team on Plus, and see, correct or delete any item whenever you like.
How is this different from ChatGPT's built-in memory?
ChatGPT’s memory keeps short notes about you inside ChatGPT. It will not hold your insurance PDF or the photo of your rego, it cannot be shared with your partner, and it cannot tell you what your address was last year. JustOnce keeps the documents and your exact words, dated, where you can open them, fix them and share them, and the AI you already use reads from it.
Can I import my ChatGPT memory into JustOnce?
Yes — every new account gets a free one-time welcome bonus of extra memories (100 on Free, 1,000 on Plus, 2,500 on Pro), and you can spend it importing what ChatGPT already knows about you. Once imported, the same memory serves Claude, Cursor, and any MCP-compatible assistant.
Is my data used to train AI models?
No — never. Your memories are never used to train models, by us or by anyone else. AI models do read your content to classify and organise it for you — that processing serves your account only, and nothing from it is used for training.
What happens if justonce.ai shuts down?
We'd give you your data. You can request a full copy of everything we hold at any time and we'll provide it in a portable format — that's your right under Australian privacy law and we'd honour it regardless. Being straight with you: a one-click self-service vault export isn't built yet. Today you can see and edit every memory in the web app and download your activity log as CSV, and we'd rather say that plainly than promise a button that doesn't exist.
I'm not in Australia — is this for me?
Absolutely. justonce.ai works worldwide with any MCP-compatible AI tool. Our infrastructure is hosted in Australia under the Australian Privacy Act — a privacy feature wherever you live.
How does justonce.ai keep my data secure?
Everything travels over TLS, and memory bodies and uploaded documents are encrypted at rest with AES-256-GCM — bodies under a key issued for their space, documents under your own key. The memory engine runs on a private network with no public address, internal access is role-restricted and recorded in an append-only audit log, and our infrastructure is hosted on Azure in Australia. One boundary we state plainly: encryption protects your data at rest — our AI pipeline reads your real content to classify and organise it, and nothing you store is ever used to train models.
What kind of data can I store?
What you dig through email for: policies, leases, bills, receipts, car rego, school forms, medical letters, the plumber’s number, plus the briefs, quotes and decisions you re-explain at work. JustOnce sorts it into 19 categories as you save. Type it, tell your AI mid-chat, hand it the file, or forward the email on a paid plan.
What is MCP integration and how does AI Memory work?
AI Memory uses the Model Context Protocol (MCP) to connect justonce.ai with AI assistants — Claude, ChatGPT, Cursor, VS Code, Windsurf, Gemini, Glama, and any MCP client. Once connected, your assistant can access your stored memories, so when you tell it your preferences, dietary requirements, or any personal detail, it remembers across every conversation. Your AI finally knows you.
How do I connect my AI assistant?
Add the JustOnce remote MCP server at https://mcp.justonce.ai and sign in with OAuth — there is no API key to copy. Claude Code and the Gemini CLI connect with a single command, Cursor and VS Code have one-click deeplinks, and Claude Desktop, ChatGPT, and Windsurf take a pasted connector URL. Step-by-step guides for every tool are at justonce.ai/connect.
Is there a free tier? What are the pricing options?
Yes! Our Free plan includes 20 memories + 10 document pages a month, 2 AI-assistant connections, and unlimited recall and search. Plus is US$8.99/month (100 memories + 120 pages, 1 shared space, email-in) and Pro is US$19.99/month (200 memories + 400 pages, 3 shared spaces, priority processing). Plans meter only what you add — recall and search are always free.
Can I export my data?
Your data belongs to you, and you can request a full copy of it at any time — email us and we'll provide it in a portable format. A self-service, one-click export of your whole vault isn't shipped yet; we're not going to claim it until it is. What you can do today: view, edit and delete any memory in the web app, download your activity log as CSV, and delete your account and its contents outright.
How do Shared Spaces work?
Plus includes 1 shared space and Pro includes 3 — add more for US$4.99/month each, every one with its own monthly allowance. Every space supports unlimited members at no extra cost, and you control access with roles (Owner, Editor, Viewer) — perfect for sharing bills, insurance policies, and family documents. Share a memory and the document attached to it goes with it, so the policy PDF is there when a member asks their assistant for it or opens the space in the web app. Members read the space in the web app, and their own AI assistants recall what was shared with them, attributed to whoever shared it.
How does search work in justonce.ai?
Unlike traditional search that matches exact keywords, justonce.ai uses semantic search to understand the meaning behind your query. Ask natural questions like 'What's my landlord's phone number?' or 'When does my car registration expire?' and justonce.ai finds the right answer, even if those exact words don't appear in your stored memories.
