# Meridian > Meridian is a 100% local, open-source productivity tool built by Meridiona. It gives you full visibility into your work — nothing goes unnoticed, everything is logged, entirely on your own device. Meridian captures the apps and windows you work in, turns that into a private daily journal, and drafts logs you review and approve before anything is ever posted to a project-management tool (Jira, Linear, GitHub Projects, Azure DevOps, or Trello). Nothing leaves your device without your explicit approval. It's not limited to developers — anyone who wants a complete, private record of their workday can use it. The app is MIT-licensed and fully auditable — free, no account required to try it. ## Product - [Homepage](https://meridiona.com/): Overview, how it works, FAQ, and download - [Product demo](https://meridiona.com/demo): Interactive walkthrough of the app ## Writing - [Writing index](https://meridiona.com/writing): Essays on AI, engineering, and work - [Your velocity went up.
