About
MemFree is an open-source hybrid AI search engine that combines the breadth of internet search with the depth of personal knowledge base search. Unlike conventional search that treats the internet and your personal content as separate silos, MemFree indexes both simultaneously — surfacing the most relevant results whether they come from the web, your saved bookmarks, or your uploaded documents.
The platform uses semantic search to understand query intent rather than just matching keywords, and AI synthesis to compose comprehensive answers from multiple sources. For researchers, analysts, and knowledge workers who maintain collections of curated resources alongside accessing the web, this unified search dramatically improves research efficiency.
As an open-source project, MemFree can be self-hosted for complete privacy — personal documents and search history never leave the user's infrastructure. The hybrid approach makes it particularly powerful as a personal knowledge management tool that evolves with the user's growing collection of curated web content.
