Tab Management
Reimagined
Tabvana tracks every tab you visit, lets you tag and search them, and uses ML embeddings to surface semantically similar pages — all without sending your data anywhere.
Features
Smart Tagging
Attach human tags to any page. System tags like #stash, #flag, and #archive help you organise your browsing at a glance.
Semantic Search
Every page gets a 384-dimensional ML embedding (all-MiniLM-L6-v2, fully on-device). Find tabs by meaning, not just keywords.
Instant Full-Text Search
MiniSearch index built at startup keeps keystroke-latency search fast even with thousands of tracked pages.
Access History
Access times are stored with varying precision — second-level for recent visits, day-level for old ones — so history stays compact forever.
URL Graph
Tabvana records opener/opened/adjacent URL relationships, powering similarity suggestions based on your actual browsing flow.
Fully Private
Everything lives in IndexedDB on your machine. No telemetry, no cloud sync, no external network requests beyond the pages you browse.
