penguinAI - Realistic AI Chat | Product Hunt
penguinAI v2 has officially released!

Built for lively chats

penguin-1.1 keeps conversations moving with playful timing, character-specific humor, and responses that feel made for the moment — from quick jokes to immersive scenes.

More than one mood

An integrated Finite State Machine tracks the emotional arc and intent of every conversation. Characters can be curious, excited, awkward, sarcastic, thoughtful, nervous, amused, or dramatic instead of replying the same way every time.

Fun that follows the scene

Characters pick up on jokes, tension, curiosity, chaos, and softer moments without turning every chat into a lecture. The FSM guides the model toward responses that fit the scene, not just the prompt.
