Meridian is an open-source, local-first AI work journal that automatically tracks every app, task, and time block throughout your workday without sending any data to the cloud. It quietly observes your activity and writes up a plain-English summary of what you worked on and what you finished, giving you a complete, searchable record by end of day. Meridian also auto-drafts status updates and worklogs matched to your tasks in project management tools like Jira, Linear, GitHub Projects, and Azure DevOps, ready to post with one click after your review. It is MIT-licensed, completely free, and requires no account or setup.
