A startup from Switzerland.
This page is designed to help you find out whether Culma is good and if it is the right choice for you.
Culma is an end-to-end encrypted knowledge base for notes, whiteboards and PDFs. Several people write in the same note at the same time, with live cursors and history per note, and the server holds only ciphertext: text, titles, folder names and membership included.
Notes are Markdown, the vault works offline, and search and dictation run on your device. Wikilinks and backlinks, tasks collected from every note, PDF import with the text in your search, and an infinite whiteboard. Folder roles and groups; a removed person loses access and the key moves. You can run the server yourself.
Free on one device, forever, with no account. Paid plans add sync and sharing. Built in Switzerland by ZNIPP GmbH; the default server is in Germany.
What Culma does not do yet: no inline comments or @mentions, no Confluence or Notion importer, no tables or database views, no single sign-on. The key model and protocol are published; the client source is not, so it is not open source.
