Branch any conversation. Keep both paths.
Fork at any point to test a different approach. The original stays intact. No copy-pasting, no rebuilding context, no losing what works.
How forking works in Aisle
Branch at any point, keep the original
Click Fork on any message. Everything up to that moment is cloned into a new thread. The original conversation stays exactly as it was. Try a different approach, compare results, and keep whichever path works better -- or keep both.
Test variations without rebuilding context
Want to try five different angles from the same starting point? Fork five times. Each branch inherits the full conversation history up to that moment. No copy-paste gymnastics, no context loss, no starting from scratch.
Go back when things go wrong
Conversation derailed three messages ago? Fork from before the wrong turn. Fix the path without discarding everything you built. Your work is never trapped in a linear timeline.
Fork lives inside Multi-Model Chat
One interface for every model, with forking, conversation history, team sharing, and version control built in.
