Frequently asked questions

Does TextoLab upload the text I enter?

No. The current text tools process your input locally in the browser and do not send it to TextoLab servers or AI providers.

Does the AI Text Detector connect to an external AI service?

No. The current detector runs deterministic statistical and structural analysis in your browser. Its score describes detected writing patterns and is not proof of authorship.

Is TextoLab free to use?

Yes. The tools currently available on TextoLab can be used free of charge.

Do I need an account?

No. The currently available browser-based tools work without registration or login.

Which languages does TextoLab support?

The interface and localized tool guidance are available in English, Brazilian Portuguese, and Spanish.

Are all results exact?

Word and character counts are deterministic. Readability, reading time, similarity, and AI-pattern analysis are estimates that should be interpreted in context.
