Why SMS replies should feel like texts
Vibeside on iMessage and SMS should sound like a person in your messages, not a chatbot essay. Here’s what we’re optimizing for.
Making images inside the chat
Ask for a new image in the thread, or pull one the character already has. Here’s when each path makes sense.
Chat formats: different ways a conversation can run
Formats change the shape of a chat. Same character, different framing. Here’s how to think about them.

Reply styles control how someone texts back. Build from a sample, or set the traits by hand, then reuse the voice.
