DeepRead.Tech

AI-native OCR platform, 95%+ accuracy, zero prompt engineering, flags uncertain fields.

OCR

Open

We are a team of founders who worked before in data extraction, with traditional manual review of each document to check accuracy / errors. We are so excited about AI and the new LLM models because we have created DeepRead using those and the accuracy is 95% and we flag uncertain fields so no one has to manually review entire documents (whew), only the exceptions! We hope you try it out and please share your review, comments and feedback. Looking forward to hearing from users!
