Free AI-powered tools for developers and content creators — improve your prompts, check content for AI tells, audit pages for AI-search readiness, and generate structured data. The detector, humanizer, schema and link tools run on heuristics in your browser; the generators optionally use a language model.
Tools for the AI-search era
Search and content workflows are being reshaped by AI. These tools help on both sides: the Prompt Optimizer gets better output from ChatGPT, Claude, Gemini and Perplexity; the AI Citation Checker scores how likely your page is to be cited by AI search engines; and the Schema Generator and Internal Link Generator strengthen the technical signals those engines rely on.
Privacy and honesty first
The AI Text Detector & Humanizer and the analysis tools run entirely in your browser using heuristics — no account, no uploads. We're upfront that AI detection is an estimate, not a guarantee, and the humanizer is built to improve clarity and natural tone, not to deceive any detector.
Frequently asked questions
Are these AI tools free?
Yes. All AI tools are free with no signup. The detector, humanizer, schema generator and link generator run in your browser; the AI generators optionally use a free language model when configured.
Is AI text detection accurate?
It's an estimate, not a guarantee. No tool can prove whether text was written by a human or an AI. Use the score as writing feedback rather than proof.
Which models do the prompt tools support?
The Prompt Optimizer tailors prompts for ChatGPT, Claude, Gemini and Perplexity, applying each model's preferred structure (for example, XML tags for Claude).
