Heynotai vs Trinka

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.
