Originality.ai vs UncovAI AI Detector Extension

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.

UncovAI AI Detector Extension checks text, images, and links on web pages for AI-generated content, manipulated images, and phishing risks. Users can scan an item with one click and see the result in the browser without leaving the page. The extension is available for Google Chrome and Mozilla Firefox, with the same core detection features in both. UncovAI describes its text detector as distinguishing human writing from text generated by models such as ChatGPT or Gemini. Image checks are intended to identify generative AI and deepfake or manipulated images; link scans flag dangerous or scam sites before a click. Checks are on demand, and UncovAI says it does not continuously log browsing activity. Its privacy policy says it may collect account, contact, transaction, device, usage, and location data, and may share personal information with service providers where needed. Plans include Freebie at €0/Month, Plus at €9.99/Month, and Pro at €19.99/month after the first month free. Zoom and Teams audio detection and WhatsApp and Telegram scam or deepfake detection are also offered.
