Linkly AI is a local-first document search engine purpose-built for AI agents. It indexes local files — including PDFs, DOCX, Markdown, EPUB, images via OCR, and audio/video via transcription — creating full-text, semantic, and outline-based indexes on the user's device. AI agents such as Claude, ChatGPT, and Codex connect via MCP or CLI to search, outline, and read documents without files ever leaving the machine unless the user opts into cloud sync. A built-in chatbot also allows users to query their document library directly within the app.
