A story partner is a different use of chat: less small talk, more construction. Anime AI is built to hold a long thread.
Start with a place
Places are easier to agree on than plots. Describe a room, a coastline or a station, and let the first scene grow from it.
Trade turns, not paragraphs
Short turns keep momentum. Save the long passages for moments that earn them.
Keep a one-line summary
End each session with a sentence about where the story stands. On Anime AI that line is the fastest way back in.
Let the character disagree
A partner who always agrees writes a flat story. The best chapters come from friction.
