AFFiNE

What it does

AFFiNE is an open-source knowledge base that combines docs, whiteboards, databases and AI in one local-first workspace. It is built for teams and creators who want to write, draw and plan without switching tools. The editor is MIT licensed, and the company offers self-hosted and cloud options.

AFFiNE is a workspace that merges docs, whiteboards and databases, with AI features available as an add-on. The homepage describes it as an open-source knowledge base and a Notion and Miro alternative. You can write in blocks, switch to an edgeless canvas for visual work, and use templates for planning. The editor is MIT licensed, and the pricing page lists a free tier for personal use with 10 GB of cloud storage and up to 3 members per workspace. Paid plans add more storage, members and support. AFFiNE AI costs $8.9 per month billed annually and includes writing, drawing and planning help, though some features are marked Beta or Coming soon. Self-hosting is available, and the company says the backend is source-available. Before choosing a plan, check the member limits, storage caps and which AI features are still in development.
