[ case study ]
Built end to end by PixnMind
Yuum is our AI video editor: on-device speech AI, a full video and photo engine, an editor you talk to, and native apps on iPhone and Android, all designed and built in-house. The same team and playbook are available for your product.
One app, two platforms
A native Android app and a native iPhone app that behave the same way, sharing one Kotlin core for the logic with no screen.
Speech AI on the phone
On-device speech recognition with word-level timing, then each word moved to where the sound shows it, so captions light up exactly on time.
Preview equals export
One renderer draws the captions for the preview, the export and the style thumbnails, so what you see at 1080p is what you get in 4K.
An editor you talk to
Yuum Live plans an edit with a frontier LLM in the cloud, the phone checks every step before it runs, and an on-phone Yuum takes over offline.
Private by default
Videos stay on the phone. Only the data an AI task needs is sent, and only when the creator picks that task.
Plans, credits & ads
Subscriptions on both stores, credit packs, and rewarded ads that take the mark off one export, all tied to one account.
