In their own words
Originality.ai
Originality.ai provides tools for checking AI-generated text, plagiarism, facts, readability, grammar, spelling and content quality. Its free Basic plan costs $0.00 per free and provides three AI scans per day, with up to 2,000 words per scan. The AI detector offers configurable allowances of 0%, 5%, 15%, 25% or 40%. A website scanner can crawl a site, identify pages likely to contain AI-generated content and run scheduled scans. The browser extension scans Google Docs, web pages or selected text, and includes writing replay, typing behavior insights and shareable reports. A REST-based API submits text for AI and plagiarism scans and returns detailed results; the maker says AI detection supports 30 languages. API AI scans require at least 50 words, and the help page says accuracy decreases below 100 words. Originality.ai describes detection results as probabilistic estimates that may produce false positives or false negatives, not conclusive proof. Pro costs $12.95 per month billed yearly, with a monthly option at $14.95 per month. The service is available through web, API and extension.
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.
