Copyleaks detects both AI-generated content and plagiarism in a single scan for text, plus AI-only detection for images. It's aimed at freelance writers, editors, publishers and educators who need to verify originality before delivering or accepting work, with flat, predictable monthly or annual tiers rather than a pay-as-you-go credit system.

Gemini is Google's flagship AI assistant, integrated across Search, Workspace and Android. Its two big advantages are a massive context window that handles enormous prompts, and native access to Gmail, Docs and Calendar — meaning it can act on your actual work instead of asking you to paste it in. The reasoning model has closed the gap with the top of the class in 2026. If you already live inside Google Workspace, Gemini is the AI that meets you where you are.
