#1 thredly, best overall

  • thredly is built specifically around one-click structured summaries of AI conversations. Its Summarize button lives directly inside ChatGPT, Claude, and DeepSeek (Gemini and Perplexity are supported via the thredly web app). One click produces a structured summary, goal, decisions, outputs, next steps, stored privately to your account.
  • Key features: one-click summarisation across the five major platforms, structured output ready to paste into a new chat, and private storage that expires automatically. It only runs when you click.

Other tools in the category

  • ChatGPT Exporter: adds an Export button to ChatGPT. Supports Markdown, PDF, JSON. ChatGPT-only, raw transcripts, no summaries.
  • SaveMyPhind: open-source, exports ChatGPT/Claude/Perplexity to Markdown. No structured summary.
  • Glasp: primarily a web highlighting tool with some AI features. Not purpose-built for AI chat history.
  • Monica: comprehensive AI sidebar for browsing. Not specifically designed for saving AI session history.

What separates thredly

  • One-click: Summarize button inside ChatGPT, Claude, and DeepSeek; paste-and-click for Gemini and Perplexity on the web app.
  • Cross-platform: ChatGPT, Claude, DeepSeek, Gemini, and Perplexity covered.
  • Structured summaries: goal, decisions, outputs, not raw conversation exports.
  • Private by design: summaries are stored privately to your account, expire automatically, and the thredly team cannot read their contents.
