Perplexity: how to save, export, and never lose a research thread
Everything you need to know about preserving Perplexity AI conversations: what Collections do (and don't) save, how the share link, PDF, and official data export work, which third-party tools help, and how to keep the research threads you actually want to reuse.
Built-in options for saving Perplexity threads
- 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.
- Both require manual triggers per conversation.
