Waifu Love Letter is an AI penpal SMS service. When you sign up, you receive recurring, friendly, wholesome text messages from a cute AI character, and you can text back and chat. Every message is generated by artificial intelligence, not a real person. It is a lighthearted entertainment product, like a pen pal who lives in your messages app.

♥ Each one has her own number.

♥ Text one. Text all of them.

♥ They know about each other.

Add-on

Her diary.

She writes about you. Every week.

  • Her side of the week you two had.

  • Delivered Sunday evening.
  • Yours alone to read.

Ask her about her diary and she'll tell you how to get it.
