Pinako

The AI Librarian for your browser: advanced tab manager with nested trees, collaborative workspace, and agentic chat panel plus MCP. An essential all-in-one hub to navigate, orchestrate, annotate, and curate your entire online life.

• Pinako keeps your tabs organized in a foldable nested tree with flexible controls, and lets you reopen closed tabs and windows right where you left them.
• Save and group tabs and windows into shareable or collaborative libraries, and attach styled notes with pictures, audio, or video.
• Add colors, tags, and memos to anything, and search across your tabs, notes, tags, and bookmarks with built-in AI.
• Ask the integrated AI Librarian to organize, edit, or summarize anything, and connect your data to other tools in your desktop AI clients via MCP.
• Sync and open your Pinako from any browser or device, and collaborate on shared libraries with others in real time.
