Architecture
Argus connects to WhatsApp via Evolution API webhooks, processes messages through Google Gemini 3 Flash Preview for entity extraction, and indexes into SQLite FTS5. A Chrome extension monitors your browser and surfaces memories proactively — no searching required.
Technology Stack
Full-text search engine with BM25-style relevance scoring, fuzzy matching and real-time indexing. Queries across 50k+ messages in under 10ms. Two-step pipeline: FTS5 retrieves candidates, Gemini validates context — no vectors, no FAISS, no embeddings needed.
Gemini 3 Flash Preview parses unstructured WhatsApp messages and extracts structured events, commitments, locations, products and recommendations in a single call — classify and extract simultaneously. Each extraction includes confidence scoring, entity tagging and full Hinglish support.
Real-time message ingestion via Evolution API webhooks. Every message is captured, processed and indexed in under 500ms. Supports individual chats, group conversations and your own sent messages. Docker-native — four containers spin up with a single command.
Proactive Chrome extension monitors your current URL and matches it against your indexed WhatsApp history using FTS5 keyword extraction. Surfaces contextually relevant memories as non-intrusive popup overlays — and watches DOM form fields to catch data mismatches in real time.
