Chat Handoff
Hit "Chat memory full" or a chat that's too long? Paste the old chat and get a short brief to start a new chat without explaining everything again.
- In the old chat, select all the text (or export it) and copy it.
- Paste it below and press Make my brief.
- Check the brief, fix anything wrong, copy it and paste it as the first message of a new chat.
Works best when messages start with "You said:" / "ChatGPT said:" (what ChatGPT copies) or "User:" / "Assistant:". Plain text works too. Or load a file:
Your handoff brief
This brief is made by simple pattern matching, not AI, so it can miss or mislabel things. Always read it first.
Better results: let the AI summarize itself
If your old chat still answers, paste this prompt there first. Then paste its reply into a new chat. You can also run its output through the tool above.
Why does this happen?
ChatGPT can only send a limited amount of text to the model per reply. Each reply re-sends the whole conversation, so a long chat eventually doesn't fit. Since about late September 2026 ChatGPT shows "Chat memory full" when a conversation reaches that limit, and offers to start a new chat with an automatic summary. OpenAI Support described it as the conversation reaching its "available memory/context limit".
This is not the same as the "Saved memories" list in Settings. Deleting saved memories does not fix a full chat (explainer).
Around 20–21 October 2026 a bug also showed the message in short or brand-new chats. On 21 October OpenAI Support said it had "applied a mitigation" (forum thread). If a short chat still shows it, report it to OpenAI.
