Local AI

Measure a prompt or try a model in the browser. Local chat and text classification need model downloads and compatible hardware.

Local AI chat

Try an on-device language model in your browser.

AI text checker

Inspect experimental text-classifier scores.

Token counter

Count tokens, characters, and words in a prompt.

Prompt cost estimator

Estimate usage with editable model pricing.

Estimate with your own rates

Token counts depend on the selected tokenizer. Enter the provider rates and expected usage you actually plan to use; the estimator is not a live pricing feed.

Treat model output as uncertain

Chat responses can be incorrect. A text-classifier score cannot establish authorship and should not be used as evidence in an academic, employment, or disciplinary decision.
