Thank You card · New
Sealed with Thanks
Messages, an envelope to open, then your letter.
Add your messages and letter, then share it as a private link. It takes about a minute.

Your messages arrive as chat bubbles, a sealed envelope waits for a tap, and a letter in your words opens on the screen before a little gift-box finale. Four colours, each with its own mood.

What they’ll see
Your messages, one by one
The card opens like a chat. Your short messages pop in as bubbles, the way a real conversation would, so they read each line before the next one lands.
A sealed envelope
Then an envelope waits in the middle of the screen with their name on it. Nothing happens until they tap it, which is the best bit to watch if you are sitting next to them.
Your letter
The envelope opens into a letter in your words, set in a handwritten-style font. Write the specific thing you are thankful for. That is the part they will screenshot.
A small finale
It closes with a little gift box. They can replay the whole card whenever they like, and send one back.
How it works

Love, Friend, Family or Mentor — each sets the mood of the whole card.
