| Spec score · AI Detection Software | 9.1 (#3) | 8.2 (#17) |
| Audio detection | Audio checks use spectral and prosody analysis and can process voice memos. | The audio detector examines voice-cloning and synthetic-speech signals including timing, spectral and speaker-consistency evidence. |
| Image detection | Image analysis uses vision-transformer based detection and can identify flagged regions. | The image detector checks diffusion artifacts, GAN output, face swaps, metadata and other manipulation indicators. |
| Integrations | The privacy policy states that Google receives information when a user chooses Google sign-in and that Google API use follows Chrome Web Store Limited Use requirements. | The product site advertises Android and iOS apps, a Telegram bot and Mini App, MCP connectivity, an agent skill and SDK integrations. |
| Security statement | The privacy policy says scan content is sent securely to the API, the extension does not execute remotely hosted code, and reasonable safeguards are used without guaranteeing absolute security. | ZeroTrue says it uses technical and organizational measures to protect the service and user data, while acknowledging that no service is completely secure. |
| Self-hosting | The maker says the API can be self-hosted for air-gapped deployments. | On-premise deployment is offered as an Enterprise-plan capability. |
| Text detection | The service uses language-model detector heads to analyze text. | The text detector highlights passages and explains writing patterns that merit review. |
| Video detection | Users can submit video, including YouTube links, for AI-generation analysis. | The video detector evaluates face swaps, lip-sync manipulation and temporal inconsistencies. |
| What it does | Heynotai checks text, images, audio and video for signs of AI generation, including essays, headshots, voice notes and deepfakes. | ZeroTrue detects signals associated with AI-generated or manipulated text, images, audio, video and source code. |

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.
ZeroTrue
ZeroTrue checks text, images, audio, video, and code for signs that content may be AI-generated, through a web checker and API. Results give an overall probability and supporting details, such as highlighted regions or timestamps, for a person to assess; they are not proof of authorship or intent. The API uses one request pattern across the listed media types, with batch processing and asynchronous webhooks among its capabilities. Python, TypeScript, and Go SDKs are listed, along with Android and iOS apps, a Telegram bot and Mini App, MCP connectivity, and an agent skill. Detection confidence can be reduced by short samples, editing, compression, translation, re-recording, mixed human and AI content, or new generators. The free web image checker accepts JPG and PNG files up to 10 MB. The free plan is free and includes 100 detections per month, API access, a web dashboard, and community support. Enterprise features include on-premise deployment, SSO and SAML, a custom SLA, and a dedicated account manager. ZeroTrue advises human review rather than relying on detector results alone for high-impact decisions.
