BookmarkBrain

Chat with your X/Twitter bookmarks and Reddit saved posts using AI.

Your saved posts are a graveyard. 🪦 No search. No recall. No value. BookmarkBrain turns your X/Twitter bookmarks and Reddit saved posts into a second brain you can actually talk to. Ask natural language questions and get cited answers grounded in what you actually saved, like having a personal research assistant over your own content. 🔑 Bring Your Own Key (BYOK) Works with OpenRouter (400+ models), OpenAI, or Google Gemini. You pay only for what you use, usually just pennies per query. The extension itself is completely free. 🔒 Privacy First All your bookmark data is stored locally in your browser. AI requests go directly from your browser to your chosen provider. No backend. No data collection. No middleman. 📖 Open Source Fully open source on GitHub under the MIT license. Inspect every line, fork it, and contribute. ✨ Features 🔍 Semantic Search Find relevant bookmarks even when exact words do not match. 📎 Cited Answers Every response links back to the original saved sources. 🤖 Auto Scroll Sync Hands free indexing of your saved pages. 💡 Insight Mode Optionally surface the Top 3 Opportunities and Risks in every answer. 📤 Export Download answers as Markdown or CSV. ⭐ Saved Prompts One click chips for your most used queries. 🎨 Themes and Customization Make the interface feel like your own workspace.
