PolyMind AI Memory
Your personal AI memory engine. Silently indexes every page you read, surfaces related content when you need it, and generates AI-powered insights from your browsing history.
How it works
From reading to knowledge — automatically
Silent Indexation
Every page you visit is chunked, embedded, and stored locally in IndexedDB. No manual effort.
Semantic Search
Find any page you've ever read using natural language. Vector search returns results in under 500ms.
Proactive Context
When you visit a page related to something you've read before, PolyMind shows a badge with linked memories.
AI Synthesis
Generate reports, timelines, gap analyses, and comparisons from your reading history using Claude Sonnet.
E2E Encrypted Sync
Pro users get cross-device sync with AES-256-GCM encryption. Your data never leaves your devices in plaintext.
Team Knowledge Base
Share memories with your team. Search across everyone's reading history in a shared workspace.
Not just another bookmark manager. True AI memory.
