What is KeepFlash, and how does it work?

KeepFlash is a personal knowledge library for saved research. Users clip webpages with a Chrome extension, upload PDFs, save YouTube videos with transcripts, and write block-editor notes with backlinks. Saved content is searchable by keyword on the free plan and by meaning (semantic search) on paid plans. AI features include automatic tagging, Auto Wiki Topic Pages that compile related notes with sources attached, PDF annotation, translation of selected text, and question answering with citations back to the source. Coding agents such as Codex, Claude Code and Cursor can be connected read-only via MCP to search the library.
