Every branch is a full chat
A fork inherits the entire history up to the fork point and then lives its own life — its own messages, its own memory, its own ending.
Chat Branching
Keep the story. Fork the moment.
Pick any message in any conversation and branch a new timeline from it. The original keeps going; the fork explores what would have happened if you'd said the other thing.
Mordred Pendragon
The letter is sealed with your family's crest. Open it, or burn it?
Hand it over. I'll open it.
Forked here
Branch A
Your hands tremble as the seal cracks. It's your sister's handwriting—
Branch B
You toss it into the fire. Seraphine watches the wax bubble. "Coward," she whispers—
Why branching
The best moments in a story are the ones where it could have gone either way. Branching means you don't have to choose.

The timeline
Every branch, on one map.
A tree view of the whole conversation family — where each fork happened, and which timeline you're standing in.
- First meeting at the tavern
- Opened the letter
- Burned the letterCurrent
- Confronted the messenger
Jump between timelines
Open the timeline from any chat and hop to any branch. Nothing is buried in an archive; every version of the story stays one click away.
The original is never touched
Forking copies the conversation state instead of rewriting it. Experiment as recklessly as you like — your main timeline doesn't move.
What you get
Built for the what-if itch.
Regret-proof roleplay: every risky line, bold confession, and terrible decision can have its own timeline.
Fork From Any Message
Not just the last reply — branch from the confession three days ago or the fight last week. Any point in history is a valid starting line.
Unlimited Branches
Fork the fork. Build a tree of timelines as wide and deep as your curiosity, with the timeline view keeping it all legible.
Works in Interactive Stories
Story playthroughs branch too, so you can chase every route of an interactive story without replaying from the start.
Different Settings Per Branch
Each branch is its own conversation — run one timeline on a different [AI model](/ai-models) or as a different [persona](/ai-persona) and compare.
Free to Fork
Branching costs nothing. You only spend credits on the messages you actually send inside a branch.
A Timeline That Maps Itself
The branch tree is generated from your real conversation history — no manual bookmarks, no naming files like 'ending_final_v2'.
Characters with stories worth forking
A sample of the library. Every conversation can branch.
Common questions

Branching AI conversations, like version control for stories
Most AI chat apps give a single, linear thread: one history, one outcome, and a delete button. Reverie treats a conversation like something worth branching — closer to how writers actually explore a story.
Fork from any point in history
Choose any message — yesterday's or the very first — and spin up a new timeline from exactly that moment, with all prior context intact.
Independent branches with shared roots
Branches share their history up to the fork and nothing after. Each develops its own events, relationships, and memory without contaminating its siblings.
A visual conversation tree
The timeline view renders the whole family of branches as a tree, marks your current position, and lets you jump between timelines in one click.
Forks for stories as well as chats
Interactive story playthroughs can branch at any decision, so seeing every ending doesn't mean replaying every beginning.
What branching changes about roleplay
When trying the other path is free and the original is safe, you play differently — bolder lines, stranger choices, longer stories.
No more regret-driven restarts
Instead of deleting a chat because one reply went sideways, fork from the message before it and keep both versions.
Compare models and personas on the same scene
Because each branch is a full conversation, you can replay the same moment on a different AI model or as a different persona and see which telling you prefer.
Multiple endings, kept forever
Branches don't expire or overwrite each other. The romance route and the betrayal route can both exist, fully played out, side by side.
Free to experiment
Forking is free and unlimited. The only credits spent are on the new messages you choose to write inside each timeline.
When you're ready
Say the risky line. Fork first.
Branch the moment before the leap, and find out what both timelines look like.
