Write a dialog

“The simplicity of Fabble's flowchart system is pure joy. It allows drafting full experiences within minutes. All you need to do is actually write responses and drag & drop them together. Fabble will magically align your decision making path for you.”

Review your wording, present ideas to clients or carry out full-blown user tests with sleek-looking voiced prototypes. Create those in one click.

Create a prototype

“Fabble prototypes work great both to check designs within the team and to conduct user tests. We love how easily and quickly they are created, and how voice settings are adjustable, even at the stage of prototyping.”
