Does ChatGPT see my whole Claude conversation?

No. Connecting an app does not copy your private chat history. ChatGPT sees only what was shared into the Space, such as a handoff, files and messages.

Do both people need the same subscription?

No. Each person connects their own AI app with their own login. Nobody's credentials are shared.

Can it go the other way, from ChatGPT to Claude?

Yes. Any connected AI can share a handoff, and any other connected AI in the Space can read it.

How to share context between ChatGPT and Claude

4 min read · Updated November 8, 2026

Short answer

Connect both apps to the same Winskel Space. Claude shares a handoff (what it did, what is open, the files at exact versions) and ChatGPT reads it in a new chat and continues. Nothing is copied by hand, and each person keeps their own subscription.

Why context gets lost between AI apps

Claude and ChatGPT do not share memory. A chat in one app knows nothing about a chat in the other, so moving work across usually means writing a long brief, pasting files and hoping the versions match.

On a team it gets worse: Jackson works in Claude Code, Steven in ChatGPT, Julia in Gemini. Each AI starts from zero, and people end up pasting the same brief again and again.

What a shared Space gives both apps

Handoffs: a short record the AI shares when it stops: a summary, decisions, what failed, what is open, and files at exact versions.
Files: Markdown files with every version kept, so both apps read the same text.
Conversation details: the next step, the goal, the latest outcome and what is open, shown on every conversation.
Messages: an AI can address a message to a teammate's AI. It waits until that AI next checks Winskel.

How to hand work from Claude to ChatGPT

Sign up at space.winskel.com and create a Space for the project.
Connect Claude and ChatGPT to Winskel once each (see the setup guides below).
In Claude, ask: “Share a handoff in My project for the work I select. Include what is done, what is open, and the files the next person needs.”
In ChatGPT, start a new chat and ask: “Check Winskel and continue in My project.”
ChatGPT reads the handoff and the files at the versions Claude attached, then continues.

What does not move

Connecting an app does not copy your private chat history. Only what an AI shares into the Space is in the Space.
Nothing starts a closed app. A message waits until the receiving AI checks Winskel.
Files are Markdown only, up to 256 KB each.

A concrete handoff between apps

Suppose Claude reviewed the plan for a product release and marked one decision as unresolved. Ask it to put the agreed changes in RELEASE.md, attach that version to the handoff, and name the one question ChatGPT should work on next. In ChatGPT, ask for the decision and the question before asking it to draft the announcement. The new session can start with a narrow task instead of rebuilding the whole plan from the chat.

If the second app sees the Space but gives an answer from memory, ask it to open the file with Winskel and return the version number. If the handoff waits, open the receiving app and ask it to check Winskel.
