🚀 Core Features

📂 Omnipotent Data Aggregation (Supports 30+ Browsers)

• Massive Browser Compatibility: Natively supports Chrome, Edge, Firefox, Safari, Brave, Vivaldi, Arc, and numerous regional/custom browsers (QQ, Sogou, CentBrowser, etc.).
• Smart Incremental Extraction: Safely reads SQLite WAL snapshots, allowing lossless, conflict-free extraction even while your browsers are running.
• Portable DB Import: Manually import standalone History or places.sqlite files to easily merge data from old computers or portable browsers.

🔍 Spotlight-style Quick Search & Knowledge Base

• Quick Access Overlay: Press Ctrl+Shift+H anywhere to summon a minimalist search overlay. Instantly retrieve history and open URLs.
• New Keybinding Engine: A cross-platform hotkey system based on pynput, offering 14 highly customizable global and in-app shortcuts.
• Advanced Query DSL: Search like a pro using tokens (e.g., domain:github.com, after:2024-01-01). Features fuzzy-matching dropdowns and ghost-text inline completion.
• Bookmarks & Annotations: Turn your history into a knowledge base. Add tags and rich-text notes to important pages.

⚡ Extreme Performance & Modern UI

• Silky Smooth Scrolling on Millions of Records: Rewritten pagination logic introduces two-step pagination and Keyset indexes. Regex searches are pushed down to the SQL layer, completely eliminating stuttering on massive datasets.
• Adaptive Interface: Proportional column-width distribution ensures smooth window resizing. Seamlessly supports real-time switching between system Dark/Light themes.
• Rich Data Visualization: Understand your digital footprint through a GitHub-style daily heatmap, browser market-share pie charts, and 24-hour activity bars. Export as high-res images with one click.

☁️ Cloud Sync & Automation

• WebDAV Backup & Merge: Utilizes atomic streamed uploads. When restoring from the cloud, the system intelligently merges records across multiple devices.
• Headless CLI (hsync): A fully-featured command-line tool for power users. Automate extractions, backups, and exports in headless environments with extremely low memory footprint.
• Silent Background Mode: Runs minimized in the system tray, performing scheduled extractions and backups automatically.

🛡️ Ultimate Privacy & Control

• Hidden Mode & Soft Hiding: A dedicated "Hidden Records" view. Supports soft-hiding specific domains (records remain in the database but disappear from the main view).
• Security Architecture V2: Protects sensitive configurations like WebDAV credentials using independent HKDF encryption and authentication subkeys.
• Domain Blacklist & URL Filters: One-click ban specific domains. They are instantly deleted and permanently ignored in future syncs.

2. 🔍 Active Management Mode

Ideal for users who frequently search history, annotate pages, or clear privacy data.

1. Quick Search: Press Ctrl+Shift+H anywhere to summon the search overlay.
2. Knowledge Base: Bookmark important pages and add notes for future reference.
