Overview

The useful distinction is breadth: one service covers five kinds of content, and its results pair an overall probability with supporting signals. That gives journalists, platform-integrity teams, and developers clues to investigate, rather than a verdict to accept. The output is evidence, not proof of who made something or why.

Key features

Review signals and limits

Highlighted text regions and timestamps can help direct a human reviewer to material worth checking. Confidence can fall when samples are short, content has been edited, compressed, translated or re-recorded, when human and AI material is mixed, or when a generator is new. Multilingual coverage is useful for broader review, but does not eliminate those weaknesses. ZeroTrue explicitly cautions against using detector output as the sole basis for high-impact decisions.

API and integrations

A shared API request pattern across all five modalities reduces the need to build separate interfaces for each content type. Batch processing and asynchronous webhooks support larger or less immediate workflows. Python, TypeScript, and Go SDKs, Android and iOS apps, a Telegram bot and Mini App, MCP connectivity, and an agent skill provide multiple routes into a workflow. This range is most valuable to developer products and review teams with an integration need; readers seeking only a quick text check may not benefit from it.

The free web image checker accepts JPG and PNG files up to 10 MB. The public website and application endpoints are served over HTTPS, but organizations considering production use should confirm data location, retention, deletion, access controls, and deployment requirements. HTTPS is a transport safeguard, not a complete answer to those operational questions.

Pricing

ZeroTrue has a free plan and paid plans with custom or usage-based terms. The Free plan costs 0.00 USD per free and includes 100 detections per month, API access, a web dashboard, and community support. Its monthly cap makes it suitable for limited evaluation or light use, not an unrestricted production workload.

The Developer plan has custom pricing, billed pay-as-you-go by modality: $0.01 per image, $0.05 per audio minute, and $0.10 per video minute. It includes unlimited detections and priority support. This is the clearest fit for developers who need metered access rather than the Free plan's 100 monthly detections; the stated rates apply to the named modalities, so buyers should confirm terms for their intended mix.

The Growth plan has custom pricing billed by volume, with volume discounts, batch processing API, asynchronous webhooks, and a dedicated Slack channel. It fits teams whose throughput and workflow needs call for those capabilities. Enterprise also has custom pricing and adds on-premise deployment, SSO and SAML, a custom SLA, and a dedicated account manager, making it the relevant option for organizations requiring those deployment or support provisions.

Platforms

ZeroTrue supports Android, iOS, web, API, and self-hosted deployment. That range spans direct checking and integration, although the specific self-hosting terms and deployment requirements should be confirmed before adoption.

Who it's for

ZeroTrue is aimed at enterprise review, journalism and OSINT, platform integrity, and developer products. It makes sense where multiple media types must be screened and people can assess the supporting signals. It is not an appropriate standalone judge for consequential decisions, especially when content has undergone transformations that can weaken confidence.

Pros and cons

Pro: Five media types share one detection service and API pattern, useful for teams handling mixed content.
Pro: Probabilities plus highlighted regions or timestamps give human reviewers more to examine than a score alone.
Pro: SDKs, apps, messaging integrations, and API workflow features offer several integration routes.
Con: Results are probabilistic, and common transformations or mixed-origin content can reduce confidence.
Con: The Free plan is capped at 100 detections per month, while Growth and Enterprise require custom pricing.
Con: Production buyers must resolve data handling and deployment requirements before relying on the service.

Alternatives

Trinka is a freemium alternative with web, API, desktop, extension, and self-hosted platforms. Grammarly is a freemium option for Android and iOS users; its Free plan includes 100 AI prompts per month, while Pro is 12.00 USD per month for 2,000 AI prompts per member per month. Sapling may suit users who want detector quotas stated in characters and files: its Free plan allows 2,000 detector characters per check, five files per batch, and 20 snippets, and it offers a free trial.

SlopProx is a freemium option for extension and desktop platforms, credited as a personal project by Ross Walpole. AI Detect is worth considering for local use: it is free, supports Linux, macOS, Windows, and self-hosting, and has no API key or usage limits. GPTZero is another freemium web, API, and extension option; its Free plan includes 10,000 words per month and 50,000 characters, and it offers a free trial. IA Checker pairs AI text detection with paraphrasing, grammar checking, translation, and summaries on web and iOS. Polygraf AI Detector is a freemium web, API, and extension alternative with a free trial; its Free plan includes 2.5K monthly tokens, roughly 2K words.

Verdict

Choose ZeroTrue if your team needs AI-content screening across text, images, audio, video, and code, and can treat its signals as prompts for human review. Its breadth and integration options are the main reasons to choose it. Look elsewhere if you need a definitive authorship judgment, or if your workflow cannot accommodate the uncertainty and operational checks that responsible use requires.
