What Heynotai is

Heynotai analyzes text, images, audio and video for signs of AI generation, including essays, headshots, voice notes and deepfakes. Users can paste text, provide an image, attach a voice memo or link a YouTube video. Results can indicate likely human, likely AI or uncertain, with a probability rather than only a yes-or-no label. Reports can include model breakdowns, flagged regions and confidence intervals, plus PDF export and an audit trail. Its API lists eight detector types: text, image, audio, video, deepfake, voice clone, watermark and paraphrase. The browser extension supports Chrome MV3, Edge and Brave, and can add a colored trust border around YouTube players. The site says text and image checks can run on-device in the extension; audio and video use the opt-in API, which can be self-hosted for air-gapped deployment. The free Check plan includes 100 tokens per month for text and image detection. Verify costs $8 a month billed annually, and Certify costs $25 a month billed annually.

Who it suits
