Got a personal agent? See what connects today

No personal agent has passed a live test yet. JustOnce is a memory and document store your assistant connects to over MCP. As of 26 October 2026, it works with Claude, Claude Code, ChatGPT (Business, Enterprise and Edu; recall only on Pro), Cursor, VS Code, Gemini CLI, Codex CLI and Glama (at the protocol level); Windsurf and OpenClaw (on your own computer only) are in testing; Gemini app, Copilot (consumer), Grok, Grok Bot, OpenAI dots and Meta Muse have no tested way to connect yet. Switch assistants or use several: your memory stays in one place, so what you save in one is already there in the next.

See, correct or erase any memory at app.justonce.ai. The board below has a note and a check date for every row.

What each row means

Transcript: This autumn, personal agents arrived. Each one is built around one person, inside one company’s apps. But you use more than one assistant, and you work with more than one person. JustOnce gives your agent a memory and a document store, in every assistant you connect. On Plus or Pro, share a space with anyone by email. Works with Claude, ChatGPT (Business, Enterprise and Edu), Cursor, VS Code, Gemini CLI, Codex and Claude Code. On ChatGPT Pro, your assistant can read your memory, but not save to it. Give your agent a memory. On screen at the end: When your assistant asks to share something or invite someone, nothing is shared or sent until you approve it in JustOnce.

What connects today.

Each row shows the day we checked it, and moves only after a live test. Names are the products’ own; JustOnce isn’t affiliated with any of them.

Works
Connects and signs in today, checked against our live server: your assistant can recall and save.
Recall only
It can find what you saved, but can’t save new things.
Testing
There’s a way to set it up, but no live test has passed yet. It may not work.
Not yet
No tested way to connect it to JustOnce yet.

Personal agents

  • OpenClaw

    on your own computer only

    Testing

    Run on your own computer, OpenClaw signs in the way JustOnce accepts. A Gateway on its own web address can’t sign in yet. Not yet tested live.

    Checked 26 October 2026

  • Grok Bot

    Not yet

    No live test of a real Grok Bot connection has passed yet, so we don’t list it as connecting.

    Checked 26 October 2026

  • OpenAI dots

    Not yet

    A dot uses the plugins in your ChatGPT account. JustOnce works in ChatGPT on Business, Enterprise and Edu, but we haven’t tested dots. On ChatGPT Pro it would recall, not save.

    Checked 26 October 2026

  • Meta Muse

    Not yet

    Meta doesn’t document a way to add an MCP memory like JustOnce to Muse, and JustOnce hasn’t added a sign-in for Muse yet.

Assistants

  • Claude

    claude.ai, Claude Desktop and the Claude app

    Works

    One custom connector on your Claude account covers every Claude app. Every plan, Free included: Free allows one custom connector, which is all JustOnce needs.

    Setup steps

    Checked 26 October 2026

  • Claude Code

    Works

    One command in your terminal, then /mcp to sign in. Or use the connector on your Claude account.

  • ChatGPT

    ChatGPT on the web (Business, Enterprise and Edu)

    Works

    Works on ChatGPT Business, Enterprise and Edu, on the web; an admin adds it for the workspace. Not offered on Free or Go; Plus unconfirmed. Through ChatGPT, JustOnce refuses to save what looks like a password, PIN, card, bank or ID number; add those in the app instead.

Your memory, not the assistant’s.

Built-in memory stays inside each company’s app. JustOnce is one place for it, so each assistant you connect starts from the same facts.

It stays in one place

Your memory lives in JustOnce, and each assistant you connect reads it. Switch assistants or use several: your memory stays in one place, so what you save in one is already there in the next.

You can see all of it

See, correct or erase any memory at app.justonce.ai. Corrections keep the old value, so you can ask what was true last March.

Paste in what it knows

Paste in what an assistant already knows and JustOnce saves it. Each assistant you connect reads the same memory and, except on ChatGPT Pro, writes to it; it’s credited when it saves something.

JustOnce is a company holding your memories too: encrypted at rest with AES-256-GCM, under keys JustOnce holds, so it isn’t end-to-end. The difference is where the memory lives, not who can’t see it.

A memory, and somewhere to share it.

The same account gives your agent a document store, and you spaces to share.

A document store for your agent

PDFs, photos and notes. Your AI reads the file, saves what it says, and keeps the original with it. Ask your assistant later what the document said; open the original any time at app.justonce.ai. JustOnce runs no OCR.

How documents work

Share with anyone

On Plus or Pro, share a space with anyone by email — no account needed. Each of them asks their own assistant and gets the answer credited to whoever shared it, or opens the space in the JustOnce web app. When your assistant asks to share something or invite someone, nothing is shared or sent until you approve it in JustOnce.

How sharing works

Personal agents, answered

Something else? Ask us.

Does JustOnce work with my personal agent?

No personal agent has passed a live test yet. JustOnce is a memory and document store your assistant connects to over MCP. As of 26 October 2026, it works with Claude, Claude Code, ChatGPT (Business, Enterprise and Edu; recall only on Pro), Cursor, VS Code, Gemini CLI, Codex CLI and Glama (at the protocol level); Windsurf and OpenClaw (on your own computer only) are in testing; Gemini app, Copilot (consumer), Grok, Grok Bot, OpenAI dots and Meta Muse have no tested way to connect yet. Switch assistants or use several: your memory stays in one place, so what you save in one is already there in the next.

What about what my agent already knows?

Paste in what an assistant already knows and JustOnce saves it. From then on, each assistant you connect starts from the same facts.

Can I get a copy of my data?

Ask us for a copy of your data any time; one-click export isn’t built yet. You can see, correct or erase any memory at app.justonce.ai. Forget means gone — there’s no restore.

Can someone else’s agent open a file I share?

Not in any named assistant yet: share the memory a file is attached to and the file goes with it — members open it in the web app. Each member’s own assistant recalls what’s shared with them, credited to the person who shared it.

Can my agent share or invite people without me?

When your assistant asks to share something or invite someone, nothing is shared or sent until you approve it in JustOnce. Approve it in the app — we ask you to confirm it’s you. Requests expire after 24 hours. Editing a memory already in a space, forgetting a memory and closing a space apply at once.

Is it end-to-end encrypted?

No. Encrypted at rest with AES-256-GCM — memories under a key for their space, documents under a key for your account. JustOnce holds the keys, so it isn’t end-to-end. JustOnce never uses your memories to train AI models, and our AI provider, Anthropic, doesn’t train on them either.

Give your agent a memory

Free: 20 memories and 10 document pages a month, no card. Connecting takes a minute at a computer.
