Free AI writing tools
Tools that help you see your writing the way a reader, or a detector, sees it. All free, no sign-up.
- AI Detector Check any text for AI writing. Get an AI score, the exact phrases that give it away, your sentence rhythm and your most repeated words. Open the tool →
- Word Counter Count words and characters as you type, and see at a glance whether your post fits X, Instagram, TikTok, LinkedIn and more. Open the tool →
Tools are most useful next to the lessons that explain what they measure. Start with perplexity and burstiness, then try the 10-minute de-robot edit on a real draft.
