Flow Designer
In September 2025, SynthFlow released Advanced Flow Designer, introducing several improvements over the original version:
- Deterministic conversation flow: Conversations now move through each node in a predictable, step-by-step sequence. This makes outcomes more reliable and easier to debug.
- Variable collection: Collect and store variables directly from users during calls, enabling more dynamic and personalized interactions.
- Deterministic branching logic: Define concrete rules—for example, if the user asks for Sales, route them to the Sales flow.
When creating a new agent, you can choose between the Original Flow Designer and the Advanced Flow Designer.
- Use the Original Flow Designer if you want a balance of flexibility and structure.
- Use the Advanced Flow Designer if you need strict, deterministic business logic.
⚠️ Note: The Advanced Flow Designer is currently in beta, and we’re rapidly adding new features.
