Recently I tried MinerU 3.1, and it’s a game changer!
- One-click conversion with perfect format preservation
- Automatic recognition of tables, formulas, and images
- Three modes available (choose Pipeline for speed, VLM for accuracy)
- Even Excel and PPT can be parsed directly
Most importantly: it’s under the Apache 2.0 license, fully commercial-friendly! The video includes a complete installation and deployment tutorial — a must-watch for anyone building a knowledge base!
