A developer has successfully reverse-engineered the Viktor file format, a proprietary system used by the popular note-taking app, Notion. The project, named OpenViktor, has been released as open-source software, providing transparency and potential for third-party tools. This effort is significant for data portability and interoperability within the developer and productivity communities.
Background
Notion is a widely-used all-in-one workspace app that relies on a proprietary file format, which can create vendor lock-in and limit user control over their data.
