Logseq

Productivity & Knowledge Management active ★ 4.6 freemium · $5/month Free tier available

Logseq is an open-source, privacy-first knowledge base that works on top of local plain-text files. It is primarily an outliner, where every piece of information is a block that can be referenced and embedded elsewhere. This block-based approach, combined with its powerful querying and whiteboards, makes it excellent for non-linear thinking and organizing complex projects.
