Dear friend is a correspondence app, not a chat app.

Pick a pen pal — Theo, a retired lighthouse keeper; Marguerite, a botanical
illustrator; Juno, a nineteen-year-old zine-maker; or Aldo, a wandering cook —
write them a real letter on ruled paper, seal it, and wait. Your pal writes
back in a few days, the way letters used to work.

The wait is not a trick. Every reply is composed entirely on your device by a
small AI that works only while your phone charges: it outlines, drafts,
critiques its own writing, checks that it still sounds like your pal, and
rewrites — again and again — until the letter is worth posting. When it's
ready, it arrives quietly in your drawer, in an envelope you open.

YOUR PALS REMEMBER

Pals keep long-term memories of what you tell them. Mention your sister in
March and Theo may ask after her in June. Over many letters a pal can even
change a little — slowly, and each in their own stubborn way.

EVERYTHING STAYS ON YOUR PHONE

There is no account, no cloud, and no server reading your mail. Your letters
never leave your device. The only things the app downloads are the AI model
itself and fonts. Delete the app and everything goes with it.

SLOW ON PURPOSE. QUIET BY DESIGN.

• No chat, no typing indicator, no streaks, no notifications begging you back
• One gentle notification when a letter arrives — never during quiet hours
• Letters live in a drawer, tied in bundles with string
• Replies are written only while your phone charges, so your battery is safe
• Works completely offline once your pen pal's model is downloaded

Dear friend is for people who miss having something to look forward to. Write
a letter tonight. In a few days, someone will have thought carefully about
what you said — and written back
