thredly: structured conversation handovers

  • thredly is built around structured handovers from AI conversations. Its Summarize button lives directly inside ChatGPT, Claude, and DeepSeek; Gemini and Perplexity use the web-app copy-and-paste workflow. The result organises goals, decisions, outputs and next steps for review.
  • 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
