Flexnote is a visual note-taking and research app built around cards on an infinite canvas. Users can arrange ideas freely, switch boards to mind-map views, connect notes with bidirectional links, and annotate PDFs or videos with timestamped references.
Notes are stored on the device by default and can be synchronized using a user's own WebDAV, S3, OneDrive, or Baidu Netdisk storage. Flexnote also supports interactive web sharing and AI indexing for semantic search and knowledge-base questions. Its free plan includes three whiteboards, 100 cards, core canvas features, and local storage; AI quotas and expanded limits are part of paid plans.
