Linkit — Your Smart Knowledge Curation Space
Linkit is a desktop bookmark manager built for knowledge workers. AI summaries, semantic search, and a knowledge graph turn saved links into real assets. Collections let you group ideas across categories; link health checks and duplicate detection keep your library clean; one-click import from Chrome, Firefox, Raindrop and more gets you started in seconds. Twelve beautiful themes, dual-track local-first storage and cloud sync — completely free with no paywalls, your data is always yours. Connect any OpenAI-compatible API or a local model (Ollama, etc.) for full AI features. Available on macOS, Windows, and Linux.

✨ Key Features
🗄️ Local-First Storage, Absolute Privacy (100% Free)
- Zero setup, no account required: All bookmarks are stored in a local SQLite database on your machine by default. Works seamlessly offline with lightning-fast sub-millisecond lookups.
- Uncapped library size: No limits on how many bookmarks, tags, or collections you can store. No hidden caps, trial periods, or functional paywalls.
- 100% data sovereignty: Your data stays on your machine. No telemetry, no ads, and zero third-party data sharing.
☁️ Free & Secure Cloud Sync (Supabase RLS)
- Real-time multi-device sync: Sign in anytime to keep bookmarks, collections, categories, and tags synchronized across all your devices.
- Enterprise-grade Row-Level Security (RLS): Powered by Supabase (PostgreSQL), each record is cryptographically bound to your
auth.uid(). Nobody else (not even the developers) can access your bookmarks. - Conflict resolution & draft protection: Built-in revision tracking and automatic merging prevent multi-device race conditions; dirty draft caching ensures zero data loss during network disruptions.
- Completely free, forever: Unlike competing tools that gate cross-device sync, full-text search, or backups behind monthly subscriptions, Linkit's cloud sync is 100% free with zero paywalls.
📥 One-Click Import
Migrate your existing bookmarks in seconds:
- Browser HTML export — Chrome, Firefox, Safari, Edge
- Raindrop.io CSV/JSON export
- Clipboard URL — paste any link directly via Spotlight (
Cmd/Ctrl + K)
💡 Knowledge Assets, Not Just Links
Every bookmark is a rich knowledge card: custom tags, star ratings, pinning, personal notes, and reading status (unread → reading → read → archived). Stop losing links you meant to revisit.
📁 Multi-Level Categories + Dynamic Collections
Build a stable category tree with drag-and-drop. Then create Collections — cross-category themed spaces with custom emojis and colors — for projects, research, or inspiration boards. Organize items manually or let AI structure them around your curation goals.
🎨 AI-Curated Collections
Break free from rigid hierarchies. Provide a natural language prompt (e.g., "Collect modern frontend tooling and design resources"), and the built-in AI will match relevant bookmarks across your library, generate a collection title and description, and recommend contextual tags. Inside any collection, a dynamic recommendation banner continuously surfaces relevant bookmarks based on content and tag similarity for one-click addition. All suggestions remain editable previews until you explicitly confirm.
🤖 Built-in AI Copilot
Note: Linkit does not provide built-in LLM services or API keys by default; users need to configure their own model.
Connect any OpenAI / DeepSeek-compatible API or a local LLM (Ollama, etc.) and unlock:
- Auto page fetch, summarization, and key takeaways
- Smart tag and category recommendations
- AI-curated collections from natural language prompts
- Semantic search across your entire library
- Duplicate detection and merge suggestions
🔍 Spotlight Search (Cmd/Ctrl + K)
Instant full-text and semantic vector search across titles, notes, tags, and AI-generated content. Also doubles as a quick-capture bar — paste a URL and save it without leaving your current tab.
📊 Curation Insights Report
Linkit periodically generates an Insights Report summarizing your curation habits: most-used tags, reading progress, content patterns, and AI-surfaced highlights from your unread pile. Turn your bookmark graveyard into an active knowledge base.
🔁 Duplicate Bookmark Detection
Automatically surface exact-URL duplicates and AI-detected near-duplicates (same content, different URLs). Review and merge with one click to keep your library clean.
