AFFiNE is redefining the digital workspace by combining the strengths of tools like Notion, Trello, and Miro into a privacy-first, open-source platform. Rather than being just a note-taking app or a whiteboard tool, it functions as an operating system for your knowledge, a unified space where writing, planning, sketching, and organizing live together on an edgeless canvas.

Its approach is block-based but without rigid constraints, enabling users to build wikis, timelines, mind maps, and prototypes in a single seamless environment. Creativity is further accelerated by deeply integrated AI, helping users brainstorm, structure content, and even generate visual artifacts like slide decks or wireframes with simple prompts.

Designed with a local-first philosophy but built for real-time collaboration, AFFiNE gives users full control over their data while enabling team-based workflows. It’s also self-hostable and customizable, with plans to support plugins and third-party blocks, making it ideal for developers and organizations seeking autonomy.

Built on inspirations like Notion’s flexibility, Miro’s canvas, and Airtable’s structure, AFFiNE embraces the best ideas while remaining open and community-driven. It's a space where freelancers, teams, designers, students, and thinkers of all kinds find the freedom to work without tool-induced friction.

If you're looking to replace Miro with a fully open, extensible, and empowering alternative, AFFiNE is a compelling place to start.
