ThreadKeep for Reddit

Capture Reddit threads, save them to history, and export them as HTML, Markdown, or JSON.

ThreadKeep helps you save Reddit threads as clean, reusable archives with the full nested comment hierarchy available from Reddit JSON. Instead of relying on bookmarks, screenshots, or messy print-to-PDF workflows, ThreadKeep captures the current Reddit post, comment tree, reply structure, and key metadata into a local archive you can revisit anytime. Use ThreadKeep to: - Capture the current Reddit thread in one click - Preserve comments with their nested reply hierarchy - Save a local archive history inside the extension - Export threads as HTML for clean reading - Export Markdown for notes and knowledge tools - Export JSON for structured workflows - Revisit saved threads from a dedicated History page ThreadKeep is built for people who research, collect, reference, or preserve Reddit discussions where the comment context matters. Good fit for: - Researchers and writers - Knowledge management workflows - Community and trend tracking - Offline reading and personal archives - Data hoarders and long-term reference What makes ThreadKeep different: - Local-first archives you control - Complete comment records with reply nesting when available from Reddit - A proper history page instead of a bookmark list - Clean export formats for reading, notes, and automation - Refresh an existing archive instead of saving duplicates Current version: - Works on Reddit post permalink pages - Uses Reddit JSON instead of DOM scraping for more reliable capture - Stores archives locally in your browser ThreadKeep does not require an account and does not upload your saved threads to an external server.
