His Letters sends you one letter a day from Dominic, a fictional character. It is one story told across 30 letters, and every letter is written by AI. It is free, with nothing to buy.
The first letter arrives immediately. After that you get one letter a day, at a time that varies, between 9 am and 11 pm in your time zone.
You can write back to a letter, up to 300 characters, until his next one is written (usually the next morning). Writing back is always optional. Your reply shapes the letters that follow.
If you leave two letters unopened, the next one waits until you open one.
The story ends with its last letter, the 30th. A copy of your letters and replies is kept on your phone, so you can read them offline.
Each letter is written for one reader, so we can only write for a limited number of readers each month. A letter may arrive late, and the app will tell you when that happens.
Every letter is written by an AI model (Anthropic's Claude) for you. The character is fictional and is not a real person. His Letters is for adults 18 and older. It is not a crisis service.
