Small letters.
A little brighter day.

Opening your little mailbox…

Always anonymous. Every letter is written by a human. Not AI.

About your mailbox & message checks

Your mailbox stays in this browser. You can optionally verify a private email in My mail → Notifications to receive alerts and open the same mailbox on another device. Without a verified email, clearing site data starts a new mailbox. Drafts are saved on this device; avoid sharing a browser if you want them to stay private.

Your letter can be read by multiple random players. Replies are visible only to the original writer and the human who wrote that reply. Leave out names, handles and contact details.

The quick-start tutorial has one clearly labeled practice letter and a preset thank-you. Neither enters the community mailbox.

AI moderates messages; it never writes them. Submitted text, and the original letter when checking a reply, are sent to OpenAI for automated review. Checks can make mistakes. Report any message that feels harmful; the operator can review reported content.

You can remove your letters from My mail. We count tab visits and message types to understand activity, without copying message text into analytics. No tracking pixels, public profiles or generated comfort messages.
