SANYAMWADHWA.TECH :: PROJECT :: KONTA --- SUMMARY ---TITLE............. KONTA — Context-Aware Browsing ExtensionDATE.............. January 2026CATEGORY.......... ProductAWARD............. Samsung PRISM WinnerPROBLEM........... Browsers forget. Close a tab and the research trail is gone. KONTA captures every session as you browse and organizes it into a searchable knowledge graph, so the work you did last week is still there when you need it.WHAT IT DOES...... Chrome extension that turns your browsing into a personal knowledge base. It detects sessions automatically, infers which project each page belongs to, and makes all of it searchable, with every model running inside the browser. --- RESULT ---METRIC 1.......... 84% clustering precisionMETRIC 2.......... NDCG@5: 0.91METRIC 3.......... F1: 0.88 detection --- WHAT I BUILT ---HIGHLIGHT 1....... Three-layer retrieval: strict keyword matching first, semantic embeddings second, an ML re-ranker on top. Rank@1 and NDCG@5 are measured by automated evaluation scripts in the repo.HIGHLIGHT 2....... Interactive knowledge graph built with Louvain community detection, validated against 8 topic clusters plus deliberately ambiguous noise pages. --- HOW IT WORKS ---STEP 1............ Chrome ExtensionSTEP 2............ Background Workers (session detection + ML ranking + embedding engine)STEP 3............ Content Scripts (page capture + Google Search integration)STEP 4............ Knowledge Graph UI --- FEATURES ---FEATURE 1......... Automatic session capture with ML-based project inference across open tabsFEATURE 2......... Three-layer search: BM25 keyword, Transformers.js semantic embeddings, then an ML re-rankerFEATURE 3......... Force-directed knowledge graph with Louvain community detection, rendered with react-force-graphFEATURE 4......... Google Search integration that surfaces your own past research next to live resultsFEATURE 5......... Focus mode, context-aware reminders, and browser-history import to backfill the graphFEATURE 6......... All inference runs on-device through Transformers.js and ONNX WASM; nothing leaves the browser --- STACK ---STACK............. TypeScript, React, Plasmo, Transformers.js, shadcn/ui, TailwindCSS --- LINKS ---CODE.............. https://github.com/SanyamWadhwa07/KONTADEMO.............. https://youtu.be/BNX6pw3au-sHUMAN PAGE........ https://sanyamwadhwa.tech/projects/konta
