MemexNG — Semantic History Search

Find anything you've ever read. MemexNG brings AI-powered semantic search to your browsing history — completely private and fully local. Instead of searching with exact keywords, simply describe what you remember.

🔍 Semantic Search

Find pages by meaning, not exact words:
- "that article about AI privacy risks"
- "React authentication tutorial"
- "video about local LLMs"
- "CSS animation performance guide"
Uses on-device AI embeddings to understand the meaning behind your searches.



🧠 Ask Questions About What You've Read

Use natural language to search and summarize information from your browsing history:
- Retrieve relevant pages
- Surface matching excerpts
- Provide cited answers with clickable source references
- Rediscover forgotten research
Every answer includes clickable source references.
