# Localize App Tutorials

App tutorials are the first experience new users have with your product, and a tutorial in a language they do not fully understand creates friction at the worst possible moment -- right when they are deciding whether your app is worth their time. Localizing tutorial videos into your users' native languages dramatically improves activation rates and reduces time-to-value.

AI dubbing makes tutorial localization fast and affordable. You take your existing English tutorials -- screen recordings with voiceover, animated walkthroughs, feature explanations -- and dub them into any target language. The AI matches the pacing of the original narration to the on-screen actions, so the dubbed version stays in sync with the visual tutorial.

This is particularly impactful for mobile apps expanding into new markets. App Store listings with localized preview videos see higher conversion rates, and in-app tutorials in the local language reduce early churn. The cost of dubbing a tutorial library is a fraction of the customer acquisition cost saved by better international onboarding.
