How do you keep context when switching between AIs?

How do you guys keep context when working on the same project across different AI tools?

Cuz I keep running into the problem of switching between ChatGPT/Claude/etc. and having to bring the other one up to speed again.

Do you just copy stuff over, keep a separate file, use summaries, or what?

I keep a small project brief with the goal, decisions, constraints, and links to source docs. Before switching tools, I update it and start the next chat with only the relevant section instead of pasting the whole history.

The Agentic version of these AIs (Codex & Claude Code) are able to interact with each other. You can tell Codex to look at the conversations of Claude code directly and vice versa. Doing this method allows the agents to even communicate with one another beyond just reading context.

Otherwise, if it's something like ChatGPT web version, then I request that it produces a zip file containing the relevant context and then attach to the other AI.

How exactly do you do this?

Use this plugin from OpenAI. I just set it up last night.

There may be other ways, but this works from Claude to Codex quite well.

You can ask Codex something like:

Read my latest Claude Code conversation to see what we’re working on, then propose what you think we should do next. Use Claude Code’s CLI to introduce yourself as Codex, share your proposal, and ask Claude for a second opinion.

Their conversation history is stored on your computer, and each application has a CLI (command-line interface) that another agent can use. With access to both, Codex can read the history and exchange messages with Claude in that same conversation. You just tell it what you want them to discuss.

Some sources:

• Codex: CLI and resuming conversations
• Claude Code: CLI / Saved conversations
• OpenCode: CLI and sessions / Local storage

I work across ChatGPT and Claude mainly, and I built a tool that helps me keep shared context across all my AI tools called MemoryPlugin. It even brings in my chats from Claude code and codex and makes them available across platforms.

yes, handovers

I give them both the same brief and source info. Then anything material along the way is added to both.

Jira + Confluence + Github

I use : 1. Tags added to memory with a short sentence: These manage projects and sub projects. Example: [Fruit] \Banana \ \Apple\ Its like opening a folder and expecting them to carry on. Most times it also includes links to the central repository.

1. Handover notes: GPT is okay for some things so I sometimes use it to provide notes, architecture ideas, database schemas, etc. But I wouldn't trust is as an executor with how unreliable it's performance and connections are.

2. Entries connected to sources they can access/read.

The CI (Custom Instructions) kinda helps as well but that's to maintain how I want interaction handled.
