Short summary
Off Grid AI Desktop is a free, open-source app that automatically turns your desktop screen captures into a searchable personal knowledge base using local AI processing. The system runs a self-filling five-stage pipeline (capture→OCR→distill→store→reflect) requiring no cloud sync, API keys, or data leaving your machine. Minimum requirements: M1+ Mac with 16GB RAM, or Windows with NVIDIA GPU and 16GB RAM.
- •Runs entirely offline with no cloud sync, accounts, or API keys required
- •Automatically captures, reads (OCR), and summarizes screen content into organized views (Day, Entities, Replay, Reflect)
- •Open-source (AGPL-3.0) with transparent data storage on your local disk
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
