What teams add voiceovers to

Product walkthroughs and demos

A silent screen recording becomes a narrated walkthrough your sales team can send. Record it once with the screen recorder and write the words afterwards.

Training and onboarding videos

Subject-matter experts record the workflow and Clueso writes and reads the narration, so nobody books a quiet room. Pair it with a written procedure from the SOP generator.

Release and feature announcements

Ship a narrated clip for each release, and edit the script when the UI changes instead of recording again. The same project gives you a step-by-step guide for the changelog.

Videos for other languages

Translate the script and auto-translate generates the voiceover in the new language. On Enterprise, your translation glossary keeps product terms intact.
