AI TRPG · BunCho Play
Play a tabletop RPG alone, with an AI as your GM
You want to play, but your group can't find a date, or nobody wants to run the game. In BunCho Play the AI takes on the GM and the characters, so you can start a session on your own whenever you like.

Real BunCho Play screens (captured October 30, 2026)
Why it works for solo play
No scheduling
Open it when you have a few minutes, play a couple of turns, close it, and resume later.
No prep
No scenario or character sheet needed. Pick a world and the first scene begins.
Take your time
Nobody is waiting on you. Think it over and write your action in your own words.
Talk to characters
Use Talk on a character to speak with just them. Each conversation counts as half a standard turn.
How one turn plays
Every screen here is the real BunCho Play, played in the isekai world without logging in.
-
Pick a world, or write one sentence
Choose a ready-made world, or describe the world you want in one line under “What kind of world do you want to play in?”
-
The first scene opens
The game master (GM) sets the scene and characters speak to you. Three suggested actions appear as A, B and C.
-
Act in your own words
Tap a suggestion, or type whatever you want to do. Actions that aren't on the list work too.
-
The GM tells you what happens
The GM narrates the result, characters react and what you've learned is updated. The next suggestions change with it.
It remembers what happened
Your adventure log sits beside the story and feeds the next turn's narration. Below: the screen after two turns.
- What you know: each fact is kept with where you learned it
- People: trust and closeness change with what you do
- Promises, items and techniques: decisions and things you picked up stay on record
- Autosave: stop any time and pick up where you left off
Worlds you can play now
Six worlds are ready. The art shows each world's backdrop and characters.

Before you play
- The story text and art are generated by AI. They may contain things that aren't true or take turns you didn't expect
- Sexual content involving minors cannot be created. In worlds with high-school characters, romantic actions are restricted
- Content that harms real people or helps with illegal acts cannot be created
- Mature settings are available only to users who have completed age verification
- If you build a world from someone else's characters or setting, mind the rights to that work
FAQ
How is this different from chatting with an AI?
There are world rules and a goal, and the story moves forward as a result of your actions. What you learn and promise is recorded and used in later narration.
Can several people play together?
Not yet; it's single-player for now.
Can I stop anywhere?
Yes, any time. Your adventure is saved automatically.
Does it cost anything?
Regular turns use no credits. You get about 30 turns without an account, and on the free plan your first 40 turns followed by 10 a day.
