Linkit R* Browser Bookmarks Local-first storage ✅ ❌ ✅ AI summaries & tags ✅ ❌ ❌ Semantic search ✅ ❌ ❌ Duplicate detection ✅ ✅ ❌ Knowledge graph ✅ ❌ ❌ Insights report ✅ ❌ ❌ Import from browsers / Raindrop ✅ ✅ — Cross-device sync ✅ ✅ ✅ Offline-first ✅ ❌ ✅ Pricing (No Paywall) ✅ 100% Free ❌ Paid Subscription ($3+/mo) ✅ Free ✨ 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. ❤ Link Health Check Background scans detect broken links (404) and silently changed pages. Filter, review, and clean up stale bookmarks before they pile up. 🌐 Knowledge Graph Visualize your entire library as an interactive network. Nodes connect via shared tags, collections, and AI semantic similarity. Click any node to jump directly to that bookmark. 📸 Interface Showcase 📊 Main Workspace (Dashboard) Three-column layout with collapsible sidebars, six view modes (grid, list, waterfall, timeline, tag-cluster, collections), and a rich detail panel. 🔍 Spotlight Search (Cmd/Ctrl + K) Instant multi-attribute and semantic search, or paste a URL to capture and analyze it on the spot. 🤖 AI Insights & Smart Summaries One-click page analysis: core takeaways, auto-tags, and a concise summary — all generated locally or via your chosen API. 🎨 AI-Curated Collections & Smart Aggregation Generate curated collections from natural language goals, with real-time similarity-based bookmark suggestions inside each collection view. 📥 Adding Bookmarks & Quick Capture Drag-and-drop or clipboard detection. AI fetches metadata and suggests tags in real time. ☁ Local vs Cloud Storage Modes Seamlessly choose between an account-free, offline local-first mode or a free cloud account with multi-device synchronization. 🤖 LLM Configuration 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 cloud API or local LLM (such as Ollama, LocalAI, vLLM). API keys are encrypted in your local OS keychain (macOS Keychain / Windows Credential Manager) and never uploaded. 💔 Link Health Check Scan for broken or changed links and filter results by status. ⚙ Preferences & Themes Twelve elegant themes (Midnight, Ocean, Graphite, Sunset, Obsidian, Aurora, Daylight, Paper, Cupertino, Cappuccino, Provence, Monet) and full English / 简体中文 localization. 🛠 Technology Stack Desktop Framework: Wails (Go) Frontend: React + Vite + TypeScript UI: Tailwind CSS + Glassmorphism design system Local DB: SQLite (via GORM) Cloud Sync: Supabase (PostgreSQL + RLS) AI: OpenAI / DeepSeek-compatible APIs or local LLMs (Ollama) 🔑 Security & Privacy Local by default: No account, no telemetry, no cloud dependency to get started. RLS-enforced sync: Cloud data is row-level secured — only you can access your records. Keychain-stored credentials: AI API keys are stored in your OS keystore (go-keyring → macOS Keychain / Windows Credential Manager). Never hardcoded, never uploaded.
