Autonomous tutorial videos for mobile apps.One sentence in.
A tutorial video out.

Kodwyn installs your app on a real device, works out where to tap, performs the walkthrough on camera and hands back a narrated, subtitled video. Nobody has to record a thing.

Launching soon. Early access opens to the waitlist first.

You write the sentence. The agent does the rest.

No screen recorder, no script, no editing timeline. You approve a plan before anything is filmed, so the video shows exactly what you meant.

The details a screen recording misses.

The gap between a screen recording and a video worth putting on your store page is all in the details. Kodwyn gets them right every run, because it made the taps itself.

1
A clean status bar

12:00, full battery, full signal, no notifications. The most obvious tell of an amateur recording, gone.

2
Real touches

Every tap and swipe is logged as it happens and drawn back as a ripple. Impossible to fake convincingly in post.

Word-by-word subtitles

Each word lights up as the narrator says it.

One recording. Every shape you need.

Switch format, backdrop, frame and subtitles as often as you like. The footage stays the same, so re-rendering takes about a minute.

Change the words. Keep the footage.

Reword a line and only that line is voiced again, on the recording you already have. No device, no new recording. Iterate until the video is exactly right.

Your login never reaches the AI.

Apps behind a login work too. The agent plans with placeholders; the real values are opened only on the device, for the moment they’re typed.

What the agent sees
{
"type": "type",
"selector": { "text": "Password" },
"value": "{{PASSWORD}}"
}
Storyboards, logs, prompts and anything you share only ever contain the placeholder.

Use a dedicated demo account: whatever is typed into a visible field, like the email address, can be seen in the video.

Sealed in your browser

Encrypted before it leaves the page. Our servers and database only hold the sealed form.

Opened on the device only

At the moment it’s typed. That device is destroyed after every run.

Never shown again

Nobody can view a stored value, including you. Replace or remove it any time.

The short answers.

Does it work with iOS apps?

Not yet. Kodwyn records on Android today. iOS is on the roadmap; join the waitlist and you’ll hear first.

My app needs a login. Is that a problem?

No. Store the sign-in details of a demo account and the agent types them in when it gets to the login screen. It only ever works with placeholders. One-time codes and captchas aren’t supported yet.

APK or Play Store link?

Either. A Play Store link works for free, public apps. Upload an APK for paid, region-locked, test or unreleased builds, and to be sure we run the exact version you expect.

What kinds of apps does it handle?

All kinds. We test on apps built with native views, Jetpack Compose, Flutter and React Native, from games and social to finance and productivity.

When can I use it?

Soon. We’re onboarding a small group of design partners first, then opening up in waves. Everyone on the waitlist gets an invite before the public launch.

What will it cost?

We’ll share pricing before launch, and the waitlist hears first. Getting a storyboard for your app will be free.

Which languages can it narrate in?

English for now. More languages are on the roadmap; join the waitlist to hear when yours is ready.

Can I be a design partner?

Yes, we’re looking for a few. Join the waitlist, then email contact@kodwyn.com with a line about your app.

Be the first to try it on your app.

No spam. One email when your invite is ready.
