| What makes it different | - Honest "I don't know" instead of hallucinated answers
- Proven improvements: 31 out of 32 correct on sealed test set
- Drops in after your existing RAG: one API call only
| - Uses multiple independent AI models to check each answer, preventing any single model from having the final word
- Shows all model disagreements and corrections visibly rather than hiding them behind a confidence score
- Transparent about limitations and does not claim to eliminate hallucinations
- Built in the EU with data processing in customer-isolated environments
