A little more than a message.

Some things deserve a letter.

The thank-you you never sent. The memory you both still laugh about. The words you haven’t quite found. Kept helps you put them into a letter they can hold onto.

Example letter · not a real user

Dear Priya,

Jo

Your words, beautifully kept.

A little guidance when you need it. A quiet space when you don’t. Always your voice.

  1. 1.

    Choose a prompt

    Pick a feeling to start from, or a blank page, if you know already.

  2. 2.

    Answer a few gentle questions

    One at a time. Optional help arranging your words, never inventing them.

  3. 3.

    Choose your paper and seal it

    Ivory, sage, ink or rose. Add a photo. Send a private link only they can open.

The loveliest part? They can write back.

One letter might begin a whole new conversation. Not a chat thread. A correspondence.

Stuck? Ask Elsie.

Elsie has written a letter a day since 1902, give or take a war. She’ll nudge you past a blank page, suggest a sign-off, or remind you that it’s never too late to write.

She’s an AI character, she never writes your letter for you, and she can’t see what you’ve written. Find her in the corner of every page.

Coming soon

From your screen to their letterbox.

Soon, we’ll take care of the paper, envelope and post too. You write the words. We’ll make them real.
