Konta
Privacy-first browser intelligence
🏆 Winner — Samsung PRISM Web Agent Hackathon
A Chrome extension that turns browsing into a private, on-device knowledge base.
What it does
- Built the Chrome MV3 extension that organises browsing into sessions, projects, semantic search and a visual knowledge graph — local-first, so nothing leaves the machine.
- Developed the interactive 2D knowledge graph with `react-force-graph-2d` and `d3-force`: zoom and pan, clustering, filtering, similarity thresholds, and semantic and project views.
- Built the user-facing surfaces in React and TypeScript across the side panel, popup, onboarding, settings and the full-page graph.
- Integrated on-device semantic embeddings with Transformers.js, `all-MiniLM-L6-v2` and ONNX Runtime Web on WASM.
- Connected the React interfaces to the extension’s background service worker through typed runtime messaging and the storage APIs.
- Built the in-page experiences via content scripts, including the Konta hub and add-to-project interactions.
