About

TiddlyWiki is a free, open-source non-linear notebook and personal wiki that stores notes in a highly flexible, hackable format.

TiddlyWiki is one of the oldest and most distinctive note-native products in the space, and it still belongs in a serious PKM catalog. It is built around modular note units, personal wiki linking, extreme customizability, and portable file-based usage. It is less polished than newer commercial apps, but that is beside the point: it remains a foundational personal-knowledge and notebook tool for users who value flexibility, ownership, and the ability to shape the system itself.
