Fill out the letter here. When you create the share link, we will ask you to sign in so the letter can be saved to your account.

How it works

How to create an Open When Letter

The creator stays intentionally small: one scene, one letter, one future unlock time, one share link.

1

Choose the moment

Start with a familiar scene such as missing someone, a birthday, a hard day, or a future date.

2

Write one personal note

Keep it direct and specific. A few honest paragraphs usually feel more intimate than a long template.

3

Set the unlock time

The letter stays sealed until the selected time. Before that moment, the body is not sent to the browser.

4

Send the sealed link

Share the generated link with your partner, friend, or family member. They do not need an account to read it.

For encouragement

For family and friends

Send a memory, thank-you note, apology, or quiet reminder that they are loved and not alone.

FAQ

Open When Letters FAQ

Do I need to sign in to create a letter?

Yes. Creating a letter requires signing in so the letter has an owner. The recipient does not need to sign in to open the shared link.

Does the recipient need an account?

No. The recipient can open the shared link directly. If the unlock time has not arrived, they will see the sealed countdown page.

Can someone read the letter before the unlock time?

No. Before the unlock time, the public page does not receive the letter body from the server.

Can I edit a letter after creating it?

Not in this first version. The product is kept simple: write once, seal it, and share the link.

Is this meant for public publishing?

No. Open When Letters are private shared-link experiences. The letter pages are marked noindex for search engines.
