Share one AI context
across ChatGPT, Claude and Telegram

Save what you worked out with one AI, continue it in another — and share the context with people in Telegram, who keep working on it in their own AI.

Get started How to connect

If the link does not open, find the bot in Telegram: @ai_contexter_bot — or open it in the app.

How it works

One context, several AI entrances.

A context belongs to you, not to the assistant. ChatGPT, Claude and Telegram are doors into the same one — no copy per tool, no re-explaining the project.

Who it's for

People like us

People who switch between AI assistants and lose the thread every time — and teams who would rather share one context than retell the project to each other.

For those who love order

…but are too lazy — or simply never get around — to keep things ordered. The bot files it; you just keep sending.

For idea generators

The ones with many, many contexts at once. Every thread keeps its spool — none of them gets lost.

For team players

Who value the time a team burns on syncing. One shared context instead of retelling the whole story again.

Getting started

Four steps to your first shared context

Not sure where to begin?

Send anything to the Telegram bot — ideas, notes, records. Every AI you connect will have access to them, and you can build contexts out of them.
Connect the AI you already use. How to connect →
Ask your AI to make your first context. Literally: Create a context called “My project” in Contexter and put my notes in it. Collect the important things there.
Keep working on the same context everywhere — GPT, Claude, Telegram, this site — and share it with friends and colleagues.

Tips

Add the bot to a Telegram group: messages of everyone who joins in are saved, and a context made from the chat is shared with those same people — each of them works on it in their own AI, outside the group.
Put it in your agent's instructions to keep the context up to date while it works on the project.
For power users: versioning for records in contexts — work together and keep the history of changes. soon

The longer reads

Shared by choice, not by default. AI chats stay private, every shared context has a visible audience, and deletion is reversible for 7 days. The whole privacy model, in plain words — about security.
Built on an open standard. Contexter is a remote MCP server with OAuth 2.1 — the address, the scopes and all twenty-six tools — for developers.
Set up your own pair. What travels between the tools, what does not, and how to connect each side: ChatGPT and Claude, ChatGPT and Telegram, Claude and Telegram.

FAQ

Questions before you start

Can ChatGPT and Claude use the same context?

Yes. Contexter is a remote MCP server that both connect to, so they read and write the same context — not a copy each. What one assistant saved, the other sees the next time you ask it.

How do I move a chat from ChatGPT to Claude without losing context?

You don't move anything. Ask the assistant you are in to save the result into a context; then open the other one and ask about that context. The records stay in one place, and both assistants reach them.

Does Contexter read my ChatGPT or Claude conversations?

No. Nothing from an AI chat is saved automatically — only the records you, or your assistant when you ask it to, put into a context explicitly.

Can I share a context with someone who uses a different AI?

That is the point of it. You share the context with a person; they connect their own assistant — ChatGPT, Claude or the Telegram bot — and keep working on the same records.

What gets saved from a Telegram group?

Only messages from the people who joined in that group; anyone who has not is not collected at all. A context built from the chat is shared with those same people.

Do I need an API key or a subscription?

No key. Connect the Telegram bot and the assistant you already use, and start. Contexter is in early access and open to everyone.

Your work should outlive the tool where it started.

Keep one context across people, AI and interfaces.
