How to make an AI video with sound on your phone

Open cirrela.com in your phone's browser, sign up with your email, and write one sentence about what you want to see. In about a minute you get a 5-second video with sound, made for your phone's screen in 9:16. No app to install, and the first video is free.

Make a free video

Your video with sound, from your phone

Open cirrela.com in Safari or Chrome and sign up with your email.
Pick Vertical (9:16) for TikTok, Reels or Shorts.
Write one sentence: who, where, what happens. “A street food cook flipping bread over a fire at night”.
Press “Make my free video”. You can lock your phone: the video keeps rendering.

Is the sound really included?

Yes. Every video level makes sound by default: ambient noise, effects, and voices when your sentence asks for them. You don't add an audio track afterwards.

Do I need an app?

No. Cirrela works in the phone's browser. To open it like an app, add it to your home screen from the browser's Share or menu button.

How to write a sentence that works

A model films what it can see: a subject, a place and one action. Add the light or the mood at the end: “at sunset”, “in slow motion”, “neon reflections”. Long lists of adjectives help less than one clear action.

Common questions

How long does it take?

The free video is usually ready in under a minute. Longer and higher quality videos take a few minutes; you get an email when one is ready.

Can I start from a photo on my phone?

Yes, from the studio: add a photo and it becomes the first frame. Only use photos you have the right to use, with the agreement of the people in them.

How do I post it on TikTok or Instagram?

Download the file, then share it from your phone's gallery or files. Make it in 9:16 so it fills the screen.
