Meet Kehai

A little moment, shared.

Nothing much happened.Except this lovely sky.

You don’t have to find the right words. Just a photo from your walk home. “That’s beautiful!” And an ordinary day feels a little warmer.

For someone you love, a little further away.

It starts with one photo.

A little of today, in three steps.

  1. Notice a moment.

    Your everyday sky. A half-finished coffee. Something small that made you feel something.

  2. Take one photo.

    Kehai draws five colors from your photo and turns the moment into a mood card. No long caption needed.

  3. Share it with them.

    Share a little of your day with your partner, family, or friends. Or keep it just for your own diary.

We’re preparing Kehai for release. Available sharing features will be explained at launch.

Q & A

A few things you might wonder.

When can I use Kehai?

The release date is not yet decided. Pre-register to be among the first to hear by email when Kehai launches.

Will it work on iPhone and Android?

We’re preparing the iPhone version first. Android is being considered, but its timing is not yet decided. Kehai is not available to download yet.

Is it free?

Preregistration is free. We plan to offer free app features and are considering optional paid features. Final features and pricing will be announced at release and shown before any purchase.

Can I use it on my own?

Yes. Turn photos into cards for your own diary. We’re making Kehai for both quiet moments to yourself and little moments shared with someone you love.

Who sees my photos? Are they sent to AI?

Your private record stays on your phone and is not posted to a public feed. When you share a card, you choose where to send it and who to share it with. Colors are extracted on your device without sending photos to an external AI service.

How will I share with someone I care about?

We’re preparing a way to share everyday cards with a small group of people you invite, such as your partner, family, or friends. At launch, we’ll explain which sharing features are available and how many people can join.

Can I leave the waitlist?

Yes. Contact kehai-support@onemu-lab.com. Your email address will not be used for advertising unrelated to the notice you signed up for.
