Updated
Calculator inputs and pasted text
The calculators in this release run in your browser. They do not upload your inputs or pasted text to a model provider or calculation server. The token counter loads its tokenizer from this site's own files.
Storage and tracking
The application does not set analytics cookies, use local storage or include third-party tracking scripts. A CSV download is generated locally when you request it. The hosting provider may process ordinary request metadata such as IP addresses, request times and user-agent strings to serve and protect the site.
External links
Following a source or related-resource link opens another website under that site's own privacy practices. Browser extensions and shared devices can have access outside this application's control.
Questions
For questions about this resource, use the operator's website. Avoid sending sensitive prompts or customer records when reporting an issue.
