Harvey is valued at $11B. Legora just raised at $5.5B. I built their entire web application in two weeks and I'm making it open-source and free for everyone to use. Say hi to Mike: mikeoss.com.

When I got the chance to try Harvey and Legora, I was surprised by how simple they were. A thought came to mind: I could probably build something similar in no time at all with Claude. And so I did.

Features:

Mike has feature parity with the Harvey and Legora web applications: 1. An assistant that can create, edit, or review documents, powered by Claude or Gemini 2. A projects vault where you can upload your files and share them with colleagues 3. Tabular review for bulk-reviewing documents 4. Workflows containing instructions for the assistant or presets for tabular review

On top of that, I added a few features unique to Mike: 1. Version control: you can save documents as new versions, and edits by the assistant are automatically saved as a new version too. So Mike can work as a full DMS like iManage. 2. A coding IDE-like interface for assistants that you can run within a project. This lets you work with the assistant while keeping full visibility of the files and documents.
