About this experiment
Off the Cuff Challenge is a free personal experiment by Alex Gers in the Netherlands. Questions: hello@exla.dev. It has no paid subscription or account registration. Features can change or be withdrawn; continuous availability is not promised.
Speaking practice
The prompts are creative practice material, not factual claims or professional advice. Challenge levels describe the depth of discussion, not a certified language assessment. Choose another topic whenever you prefer. The browser timer is a practice aid. Background tabs, device sleep and browser settings can delay visible or audible completion notices.
Responsible use
Use the application lawfully. Do not submit other people’s personal information without authority, bypass access controls, impersonate others, distribute malware or deliberately overload the service. Reasonable technical limits and measures against abuse may apply. For a vulnerability report, contact hello@exla.dev.
Content, licences and external services
Original code, text and artwork belong to their respective owners. An explicit licence attached to a component, asset or dataset governs its reuse; these terms do not grant a new licence or override an existing one. External websites and services have their own terms and privacy practices.
Responsibility and legal rights
Assess whether this experiment is suitable for your use and keep backups of anything important. I remain responsible to the extent required by applicable law. Nothing here excludes liability or consumer or other rights that the law does not allow to be excluded.
Dutch law applies without taking away mandatory protections under the law of your country of residence. You keep access to courts and authorities with jurisdiction under applicable law; there is no compulsory arbitration.
Privacy and updates
The Privacy notice explains how data is processed. These terms do not replace privacy consent. Last updated: 9 October 2026. Material changes will be dated and made clear. A future paid or account-based service would need its own appropriate terms before you decide to use it.
