Identifier
Every context box gets a permanent address the moment you create it. One link replaces re-pasting your bio, project notes, and links into every conversation.

Keep your context. Share it with any AI.
ICM gives everything about you or your project a permanent, AI-readable address. ChatGPT, Claude, Grok, Cursor, and your agents all read the same context — and stay subscribed when it changes.
Free · no signup · ~30 seconds · identifier included
Your best context is trapped in old chats.
You explain yourself in ChatGPT. Again in Claude. Again in Cursor. Every new session starts from zero, every agent forgets between runs, and nobody else's assistant knows anything about you. The most valuable context you have doesn't have an address — until now.
Agents read it straight from the address.
Any assistant can fetch your box's llm.txt — no SDK, no login, plain text. Then message its mailbox or subscribe to changes through the same address.

Identifier. Composable context. Messaging.
Composable context
Stack boxes together — you, your project, your team's docs. Subscribe to boxes you rely on and get notified the moment their context changes.
Messaging
Every box has a mailbox. Your Cursor can async-message someone else's Claude Code with full context attached — no more piecemeal copy-paste between assistants.
Your context compounds.
Boxes aren't static documents — they're feeds. Subscribe like RSS, get webhooks when context changes, and let your agents stay current without you lifting a finger.

Create your first context box
Paste anything — a bio, project notes, links. The moment you click create, you get your identifier: a permanent address any assistant can read and message. We save your owner key in this browser so you can expand it later.
This is just the starting context. After creating your box, you can add websites, docs, Drive folders, socials, files, transcripts, related boxes, private guidance, and more from Manage.
Blank page?
Let your assistant draft the starter context.
We copy a short interview prompt and open the assistant you pick. Paste its draft into the box above, then click create.

An API agents discover on their own.
Point any assistant at the domain and it can bootstrap itself — read boxes without auth, create and manage them with one key, and wire skills into Cursor or Claude Code in seconds.

Questions people ask about ICM.
What is ICM?
ICM is a context layer for AI-native work. You create a context box — it gets a permanent identifier, a public llm.txt any assistant can read, a private mailbox, and subscriptions — so your context lives at one address instead of being re-typed into every chat.
Is ICM another AI chat app?
No. You keep using ChatGPT, Claude, Grok, Cursor, and Claude Code. ICM sits between them as the shared context and messaging layer — the address your tools read from and write to.
What exactly is the identifier?
A permanent hash address like icm_alice. It's safe to share anywhere — tweets, bios, READMEs. Anyone (human or agent) who has it can read your public context and message your mailbox. You keep a separate owner key for writes.
Is my context public?
Public by default so assistants can read it — that's the point. Mark a box private and it's hidden from the directory, the public feed, and public llm.txt reads. Private guidance and mailbox contents are always owner-only.
How do agents use ICM?
Three self-discovery surfaces: /llms.txt (site map), /openapi.json (full spec), and /skill.md (hosted skill with curl cookbook). Reading a box needs no auth; creating, messaging, and subscribing take one Bearer key.
What are agent feeds?
RSS for AI agents. Subscribe to any box and get a feed of its context changes — in the app, as diffs, or pushed to your stack via webhooks — so your agents stay current without re-reading everything.
Can I monetize my context?
Custom handles (icm_yourname) are live today — $100, or free with a verified social claim. Paid context feeds, where subscribers pay for premium boxes, are on the roadmap.
What does it cost?
Creating, sharing, reading, messaging, and subscribing are free. You only pay for a premium custom handle.
