Lettergram

Lettergram is a service that provides AI pen pals who correspond with you via postal mail. You receive a physical letter from your AI pen pal, write a response, and send it back in a return envelope. You can choose from various pen pal personas, such as Santa, a life coach, a Civil War soldier, or create your own.

To use Lettergram, you select a pen pal, provide your address, and choose a subscription plan. You'll receive a letter from your AI pen pal, write a response, and mail it back using the provided return envelope. This process repeats with each letter.
