| Description | KeepFlash is an AI bookmark and personal knowledge manager that lets individuals save webpages, PDFs, YouTube videos, files, and notes into one library they can search, annotate, and question with AI. It's aimed at researchers, students, and writers who want scattered material reconnected into an askable knowledge base, with the original source, body, tags, and context preserved so answers come back with citations. Its standout is Auto Wiki, which groups related saves into compiled Topic Pages, plus read-only MCP access that lets AI coding agents like Codex, Claude Code, and Cursor search your saved library. | Capacities is a note-taking and personal knowledge management app that structures everything you capture—people, books, projects, ideas—as connected objects with properties rather than flat pages in folders. Objects link to each other to form a knowledge graph, with backlinks and automatically surfaced related content revealing connections between notes. It also includes an AI assistant that writes, summarizes, and surfaces links between objects, and centers daily notes as a low-friction inbox for capturing thoughts. |
