Smart Text & AI Tools
Tools that analyze writing: pull the key sentences out of a long article, find the main keywords, estimate the tone of a review, count AI tokens for prompts, and build better prompts.
To be clear: the live tools here use proven statistical language techniques that run on your device. They do not send your text to a large language model. Generative tools that need a server-side AI model are listed as “Coming soon” until we can offer them properly.

Smart Text tools: common questions
Do these tools use ChatGPT or another AI model?
No. The live tools use local, statistical methods (sentence scoring, word frequency, sentiment lexicons). They're fast and private, but they don't rewrite or generate text.
Will you add generative AI tools?
Yes, when we can run them properly on a server. Until then they're listed as coming soon instead of being faked.
