How to summarise AI conversations automatically

If you want to summarise AI conversations automatically — without manually copying, prompting, or doing anything when each session ends — the options are limited but growing. This guide explains what's possible across ChatGPT, Claude, Gemini, and Perplexity.

Start free on Chrome

What each platform offers natively

  • ChatGPT: no automatic summarisation. Memory stores small facts across conversations — not session summaries.
  • Claude: auto-context management on paid plans compresses messages when approaching the context limit. For the conversation, not for saving a summary.
  • Gemini: no automatic summarisation. Stores history with an 18-month retention window.
  • Perplexity: no automatic summarisation. Collections let you organise threads but don't generate summaries.

None of the major AI platforms auto-summarise your conversations for you

  • The manual workaround is to ask the AI to summarise before you leave each session — but this requires you to remember every time. The value of automatic summarisation is that it happens whether you think about it or not.

One-click summarisation across AI tools: thredly

  • thredly is a Chrome extension that adds a Summarize button inside ChatGPT, Claude, and DeepSeek. One click on a long thread and you get a clean, structured summary stored privately to your account. For Gemini and Perplexity, paste the conversation into the thredly web app and click Summarize. It only runs when you click; summaries expire automatically and the thredly team cannot read their contents.

Frequently asked questions

Can I set up automation tools to auto-summarise my conversations?

Not without custom development — there's no public API from ChatGPT or Claude for automatically triggering summarisation via tools like Zapier.

How is this different from AI note-taking tools like Otter or Fireflies?

AI note-taking tools are primarily for meetings and spoken conversations. thredly is specifically built for AI chat — the typed conversations you have with ChatGPT, Claude, Gemini, and Perplexity.
