Flexnote is a local-first visual note-taking app for deep learning and research. Capture ideas as cards, arrange them on an infinite canvas, and connect them with mind maps and bidirectional links. Annotate PDFs and YouTube videos, then use Flexnote AI to search, summarize, and organize your own knowledge base. Notes stay on your device by default, with optional sync through OneDrive, S3, or WebDAV. Free to start on Windows, macOS, and Android. Flexnote is built for students, researchers, and anyone who learns from papers, courses, and long videos. Notes are cards, not long documents. You place them on an infinite canvas, link them, and turn a board into a mind map when you need the structure. Flexnote AI works on that same library. Ask a question and answers come back with citations from your notes. On a card you can summarize, translate, or generate a mind map without opening a long chat. The agent can also add sticky notes, links, and groups on the whiteboard, and write a conclusion into a new card. Chat uses your own model API key (DeepSeek, Tongyi, and other providers). Flexnote does not use your notes to train models. The desktop apps run on Windows 10 or later and macOS 11 or later. An Android app is available. The website currently only lets you view a published whiteboard. iOS is still in development.
