ChatSim lets you script a mobile chat conversation and play it back like a real iOS or Android messaging app, in light or dark mode. Add typing delays, quick replies, voice notes and link previews, mirror it on a phone, and import or export the flow as JSON. It is useful for prototypes, demos and user testing.

How to use ChatSim

  1. Add messages, choices and delays in the builder.
  2. Pick an iOS or Android theme and press play.
  3. Open the mobile view to demo it on a phone, or export the JSON.

Frequently asked questions

Yes. ChatSim lets you toggle both the mobile OS skin (iOS or Android) and Light/Dark appearance dynamically.
How can I save or share a ChatSim conversation flow?
Use Export JSON to download your complete conversation configuration and Import JSON to reload it on any device.
