Questions & Answers

If you have any other questions, please get in touch

Is CaptureLab really free to use?

Yes. You can open the web studio and start recording without paying or creating an account.

Does CaptureLab only work in Google Chrome?

The web studio uses modern browser recording APIs. Chrome offers the best-supported experience, and the optional extension adds a shortcut from the current tab.

Can I record tab audio and microphone at the same time?

Yes. You can capture browser tab audio and your microphone together for guided demos.

Do I need an account before I can start recording?

No. Recording, editing, and exporting happen locally in your browser without an account or cloud upload.

How long can a recording be?

Most users can record complete walkthroughs without issues. For very long sessions, we recommend splitting content into shorter chapters.

Can I trim or polish clips before sharing?

Yes. You can quickly trim recordings and clean up the final result before sending it.

How do I share my recordings with my team or clients?

Export the finished recording as a local video file, then share it through the channel of your choice.

Is CaptureLab suitable for sales demos and support videos?

Absolutely. CaptureLab is made for short, clear product demos, onboarding clips, and support explanations.
