AI Utilities covers 14 tools split into two groups. Four run entirely in your browser: Word Counter and Token Counter analyze text locally with no server involved, while AI Model Comparison and AI Cost Calculator are reference tables you can browse offline. The other ten — Prompt Optimizer, Shortener, Expander, Translator and Generator, AI Image Prompt Generator, SEO Title Generator, Meta Description Generator, Email Writer and Rewrite Tool — send your input to a shared AI model over our own API to generate a response, then discard it.
The most-used tools here tend to be the Prompt Optimizer for sharpening a rough prompt before sending it to any AI model, and the Rewrite Tool for quickly adjusting a passage's tone or length. Token Counter is popular for estimating cost before calling a paid API elsewhere.
Everything in this category is free, with no signup, and works with GPT, Claude, Gemini and other AI models rather than being tied to one provider. Word Counter and Token Counter never send text anywhere; the ten generation tools send input to the shared AI model only long enough to produce a response, then discard it — nothing is stored afterward.
