About Telltale Proof
Built by Colin at Web Thrive
Why we built this
AI writing tools have become part of everyday work. That's not inherently a problem — but it has created a real need for transparency. Teachers want to know if a student wrote their own essay. Editors want to know if a pitch is authentic. Publishers want to know if the voice they're buying is real.
Most AI detectors give you a single score and a verdict with no explanation. We thought that wasn't good enough. Telltale Proof was built to go deeper — to show you why something scores the way it does, not just what the verdict is.
We also wanted it to be free. Content creators, students, and small publishers shouldn't need a subscription to understand their own writing.
How it works
Telltale Proof analyzes text across 8 sections and 32 individual signals — from sentence structure and word choice to cognitive fingerprinting and emotional texture. Each factor is scored independently and explained in plain language, so you can understand exactly what's driving the result.
The analysis is powered by Claude, Anthropic's AI model, which evaluates writing the way a trained human editor would — looking for the subtle patterns that distinguish authentic human prose from generated text.
The Human Score
Rather than labeling text as "AI" or "human" with false confidence, Telltale Proof gives you a Human Score out of 100. Higher scores indicate stronger human writing signals. Lower scores indicate patterns more consistent with AI generation.
These are probabilistic signals, not verdicts. A score of 72 doesn't mean a text is definitely human-written — it means it exhibits strong human writing characteristics across the 32 signals we measure.
