#1 thredly, best for one-click summarisation

  • thredly is a Chrome extension that adds a Summarize button inside ChatGPT, Claude, and DeepSeek. One click on a long thread produces a clean, structured summary stored privately to your account. Gemini and Perplexity are supported by pasting into the thredly web app. It only runs when you click.
  • The summaries are structured (goal, decisions, outputs, next steps) rather than raw transcripts, which makes them actually useful for resuming work.

Why raw exporters fall short

  • Every other Chrome extension in this category gives you raw transcripts you still have to read. You export, then you have a long unstructured wall of text to wade through later.
  • thredly's one-click button hands you the structured summary directly, so the saved version is the one you'd actually reuse.

Other tools compared

  • ChatGPT Exporter: ChatGPT-only, exports raw transcripts not summaries.
  • SaveMyPhind: three-platform, exports Markdown transcripts. No structured summary.
  • Glasp: primarily a web highlights tool, not a chat summariser.
  • thredly is the only Chrome extension built around one-click structured summaries across ChatGPT, Claude, and DeepSeek (with Gemini and Perplexity via the web app).
