How to save Perplexity AI conversations
Perplexity AI is a powerful research tool — but saving and organising your conversations for future reference is something it doesn't make easy by default. This guide covers everything available, from built-in features to automatic solutions.
Built-in options
- Perplexity Collections: bookmark any thread to a labelled Collection. Good for organising related research — but it's a reference, not an export.
- Share link: generates a public URL of any thread including cited sources. Not a true archive.
- Export to PDF: Ctrl/Cmd+P → Save as PDF for individual threads.
- Official data export: account settings → data export. Provides conversation history as JSON — complete but not human-readable.
Third-party export tools
- SaveMyPhind: exports Perplexity conversations to Markdown. Free and open source.
- Perplexity to Notion extension: syncs threads to Notion automatically.
- These all require manual triggers per conversation.
One-click summaries with thredly
- For Perplexity, paste the research thread into the thredly web app and click Summarize. You get a clean structured summary stored privately to your account, ready to reuse alongside summaries from your other AI tools. (thredly's in-page Summarize button is on ChatGPT, Claude, and DeepSeek; Gemini and Perplexity are supported via the web app.)
