About Flexnote

Flexnote is a local-first visual note-taking application. Notes, PDFs, videos, and web pages can each become a card. Arrange, group, and connect those cards on an infinite canvas to show the structure of a topic. The product serves individuals who want to study, research, and manage projects over time, using cards, links, and AI to organize complex content without forcing collaboration in real-time.

Flexnote centers on a local-first philosophy. By default, notes stay on the user’s device, and editing remains available offline. Synchronization across devices is optional and relies on the user’s chosen cloud storage services, such as Baidu Netdisk, OneDrive, S3, or WebDAV. The system supports publishing boards as shareable links, with view-only access.

Flexnote provides a structured canvas workflow with features like PDFs and videos annotations, bidirectional linking, and a knowledge-base AI that answers from indexed notes and media. Users create highlights, timestamps, and cards that serve as reference points, while the interface maintains a left-side menu of persistent entries and a top tab bar for navigation.

Flexnote lists its platform availability and pricing on the pricing page, with details about plans, cloud sync, and multi-device support. It also mentions iOS development and a roadmap for a full web app, indicating ongoing platform expansion and feature development.
