Copyleaks AI Detector vs UncovAI AI Detector Extension

Copyleaks AI Detector identifies AI-written text, including writing that mixes AI and human passages. It supports more than 30 languages and names GPT-5, GPT-4, ChatGPT, Claude, Gemini, DeepSeek, Llama, Bloom, Rytr, and Jasper among the sources it detects. AI Logic explains flagged results, displays AI phrase frequency, and can identify text appearing in published content elsewhere. The web detector scans up to 25,000 characters without login; the website platform requires at least 255 characters and accepts up to 2,000 pages. A Chrome and Edge extension accepts 350 to 25,000 characters, and a Google Docs add-on and education LMS integrations connect it to other workflows. Personal costs $13.99 a year with annual billing or $16.99 a month; Pro costs $74.99 a year with annual billing or $99.99 a month. A free plan and free trial are listed. Copyleaks says data is encrypted at rest with AES-256, reports SOC 2 and SOC 3 certifications, and supports GDPR compliance.

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.
