Memory

One memory for every bot.

Extent keeps a library about your world: people, projects, places and plans. Every bot reads it before it answers and adds what it learns.

Ola lives in Kraków now. The Friday 17:05 from Warsaw gets you there at 19:30. Want me to book it?

01

You mention it.

Tell any bot a fact, or forward the email that says so.

02

Extent files it.

It updates Ola's page and notes that the fact came from you.

03

Every bot knows it.

A new chat with any bot, or with Claude Code, gets the fact back.

Built to be read, fixed and trusted.

Writes plain Markdown.

Each person, project and place is one file. You can read it, fix it or take it with you.

Cites its sources.

A fact from an email, a web page or another bot says where it came from.

Keeps corrections.

Fix a fact and the old wording stays, dated, so you can see what changed.

Saves what you send.

Share a link, a photo or a PDF from any iPhone app. Your main bot files it under the right person or project.

Listens only to you.

Only your own messages change a fact. Mail, web pages and other bots add notes marked with their source.

Opens to your agents.

Claude Code, Codex and Cursor read and add to the same memory over MCP.

Extent is in early access.

iPhone and Mac. Bring your Claude or ChatGPT plan.
