| Spec score · AI Detection Software | 9.1 (#3) | 7.1 (#28) |
| Audio detection | Audio checks use spectral and prosody analysis and can process voice memos. | Audio and video elements are checked for spectral flatness, silence regularity, and pitch jitter. |
| Image detection | Image analysis uses vision-transformer based detection and can identify flagged regions. | Image detection uses pixel-level heuristics and checks known AI image sources including Midjourney, DALL·E, Stable Diffusion, Leonardo, and Ideogram. |
| Privacy | The site says the extension runs locally, the API is opt-in, and the product uses on-device processing with zero retention by default. | The maker says detection runs on-device, data is not uploaded, and there are no accounts or tracking. |
| Text detection | The service uses language-model detector heads to analyze text. | Text checks use signals including burstiness, common-word ratio, phrase fingerprints, and syntactic uniformity. |

In their own words
Heynotai
Heynotai detects whether text, images, audio, video, essays, headshots, voice notes, and deepfakes are likely AI-generated. Users can paste text, drag in images, attach a voice memo, or link a YouTube video. Results are labeled likely human, likely AI, or uncertain with a probability rather than a binary answer. Reports can show model breakdowns, flagged regions, confidence intervals, PDF export, and an audit trail. One API lists detectors for text, image, audio, video, deepfake, voice clone, watermark, and paraphrase. The extension supports Chrome MV3, Edge, and Brave, and can add a colored trust border to YouTube players. The Check plan costs nothing with 100 tokens per month for text and image detection. Verify costs $8 a month billed annually, and Certify costs $25 a month billed annually. Text and image checks can run locally; audio and video use the opt-in API.
