Overview

Heynotai is an AI-detection service for text, images, audio and video, with web, browser-extension, API and self-hosted options. It suits teams that need to check several media types and preserve a record of results. Its range of inputs and deployment choices is a strength, but the low free quota and split between on-device and API checks make plan limits and data handling central to the decision.

Key features

Users can paste text, attach images or voice memos, and submit YouTube links. Results classify content as likely human, likely AI or uncertain, with a probability rather than a forced binary verdict. That is a more cautious format for review workflows, though a probability is not proof of authorship.

Reports include model breakdowns, flagged regions and confidence intervals, with PDF export and an audit trail on Certify. The API brings together eight detectors for text, image, audio, video, deepfakes, voice clones, watermarks and paraphrase. That breadth can simplify integration for teams working across formats; the service does not describe the detectors as a substitute for human judgment.

The Chrome MV3 extension also supports Edge and Brave, and can add a colored trust border to YouTube players. Heynotai reports internal benchmark accuracy of 96.3% for text, 94.1% for images, 91.7% for audio and 89.4% for video. Those figures indicate the company’s reported results, not a guarantee for an individual scan.

Heynotai says the extension runs locally, uses on-device processing with zero retention by default, and sends scan content securely to its API when needed. Text and image checks can run in the extension; audio and video use the opt-in API. The API can be self-hosted for air-gapped deployments, a useful option for teams with strict isolation needs. The extension does not execute remotely hosted code, and the privacy policy says it does not collect general browsing history or log clicks, scrolling or keystrokes.

Education customers get flat per-seat licensing, and student essays are shown with regional flags rather than scores. Users can appeal verdicts in-product; Team customers also get a private retrieval index for their content style. These are targeted safeguards for educational and team review, rather than a general answer to the risk of false positives.

Pricing

Check is free at 0.00 USD per free and includes 100 tokens per month, AI text and image detection, confidence scores and sentence-level highlights. It is suitable for occasional checks, but 100 monthly tokens sharply limits regular use and excludes the broader paid-plan features.

Verify costs 8.00 USD per month, billed annually at $100 / yr. Its 10K monthly tokens, browser extension, paraphrase and tone forensics, and priority support suit individuals or small-scale workflows that need the extension but not shareable reports or API access. The annual billing commitment matters if usage is uncertain.

Certify costs 25.00 USD per month, billed annually at $300 / yr. It raises the allowance to 50K tokens per month and adds shareable reports, a 12-month audit trail and API access. This is the clearer fit for teams integrating checks or documenting decisions; it still carries an annual commitment and a fixed monthly quota.

Team has custom pricing, custom monthly tokens, shared collections and monitors, SSO, role-based access and a dedicated success manager. It is aimed at organizations needing administration and shared workflows; teams should confirm the token allowance and price before choosing it. Education licensing is flat per seat.

Platforms

Heynotai runs on the web and through an extension, and offers API and self-hosted deployment. The local extension path covers text and image checks, while audio and video depend on the opt-in API. Self-hosting the API supports air-gapped deployments, but does not make every check local in the browser.

Who it's for

Heynotai is a strong candidate for teams checking multiple media formats, educators who want regional rather than numerical essay flags, and organizations that need audit trails or isolated API deployment. It is a weaker fit for high-volume users who need a generous free allowance, or anyone expecting every media check to run offline.

Pros and cons

Pros: One API spans eight detector types, reducing the need to assemble separate integrations for the listed media and checks.
Pros: Local text and image checks, zero retention by default and an air-gapped self-hosted API give privacy-conscious teams deployment choices.
Pros: Confidence intervals, flagged regions, PDF reports and audit history support review and documentation rather than a bare label.
Cons: The free plan’s 100 tokens per month is too small for sustained use.
Cons: Audio and video checks rely on the opt-in API, so those formats do not share the extension’s local processing path.
Cons: Verify and Certify are billed annually, and Team’s custom pricing requires a separate purchasing decision.

Alternatives

For a broader comparison, see AI Detection Software.

GPTZero is worth considering if a larger free text allowance matters: its free plan includes 10,000 words per month and 50,000 characters, compared with Heynotai’s 100-token monthly allowance.

Trinka is an alternative when its broader platform availability, including macOS and Windows alongside API, extension, self-hosted and web access, better matches the stack.

Polygraf AI Detector may fit users who want a free allowance of 2.5K monthly tokens, or about 2K words, rather than Heynotai’s 100 tokens.

Sapling is another option for teams comparing API, extension, self-hosted, web and Windows access.

ScribeLens may suit users prioritizing a free 35,000-token monthly allowance and seven PDF report exports per month.

Winston AI is an alternative to evaluate if its free 14-day trial and 2,000-credit allowance suit an evaluation period.

Airno offers a free tier with 100 API requests per month for text and image detection, making it a relevant comparison for API-led workflows.

Originality.ai may suit occasional users who prefer a free option with three scans per day, up to 2,000 words per scan, and document uploads.

Verdict

Choose Heynotai if your team needs one service for several media types, useful reporting and a choice between local checks and self-hosted API deployment. Its best case is a team or education workflow where evidence, privacy controls and deployment flexibility matter. Look elsewhere if you need a meaningful free volume or expect audio and video checks to run locally.
