Using the calculator
You may use the calculator for personal, educational, and workplace planning. The current tool is free and requires no account. Do not disrupt the site, attempt unauthorized access, or use it for unlawful activity.
Estimates, not guarantees
Results are mathematical estimates based on your input and selected speaking rate. They do not guarantee the length of a real presentation. Pauses, pronunciation, language, emphasis, demonstrations, and audience interaction can change the outcome. Verify important timings through rehearsal.
You are responsible for the accuracy of your inputs and how you use the results. The informational content is general guidance, not professional advice.
Your text and privacy
You retain your rights to the text you enter. Using the calculator does not transfer ownership of your script. Pasted text is processed locally; analytics and technical request data are handled as described in our Privacy Policy.
Availability and changes
Features and content may change, and access may be interrupted. We do not promise uninterrupted availability or that the tool will meet every user's requirements.
Disclaimer and limitations
To the extent permitted by applicable law, the site is provided as available without warranties about accuracy, availability, or fitness for a particular purpose. To that same extent, the site's operators are not responsible for losses caused by reliance on estimates or interruptions to the service.
Nothing in these terms excludes rights or liabilities that cannot lawfully be excluded.
Updates to these terms
Revised terms will be published here with an updated date. Review this page when using the service after significant changes.
