| What makes it different | - Completely free for single-track checks with no signup or account required
- Publishes full methodology, per-track results, and failures transparently
- No storage of user audio or use of uploads for training
- Withholds inconclusive verdicts when evidence is weak rather than guessing
- One-time paid credit packs with no subscription or auto-renewal
| - Measures attention directly from the model's computation rather than asking the model to cite itself, providing verifiable attribution
- Achieves frontier-grade citation quality at 7x lower cost and 5-6x faster than alternatives
- Never confused by duplicate facts—identifies the exact occurrence the answer used even when values appear multiple times
- Lands on exact tokens down to character level, not just document chunks
- Works on any model's output post-generation without modifying inference pipeline
