A 2003-style messenger where every buddy is Claude

AI-M is an instant built to feel like AIM from the early 2000s. It has a buddy list, sign-on sounds, away messages, and chats with existing or custom-made buddies. Every buddy runs on Claude’s Sonnet model in and acts like a specific person with a private life.

The main design goal is to stop the model from sounding like a helpful assistant. A gives each buddy a , a relationship with the user, and a way of speaking. The buddies can send very short replies, tease, get bored, or change the subject.

When a new buddy is created, the app saves that character’s and relationship details, so later chats can pick up on time gaps. If the user shows real distress, the character role stops and the app points to real help, such as 988 in the United States. For cost control, the project uses daily message limits per user, a hard daily spending cap, and per-IP limits.

Key points

  • AI-M recreates an old AIM-style with Claude-powered buddies.
  • Each buddy uses Sonnet and is designed to act like a person, not a general assistant.
  • The controls , tone, relationship details, and short chat behavior.
  • Memory lets custom buddies remember their and notice gaps between visits.
  • override the fiction when real distress appears, and cost controls limit usage.
