Flow Builder
Flow Builder
Design AI voice conversations visually with a drag-and-drop node editor.
The Flow Builder is Talkif's visual conversation designer. You build voice agent logic by placing nodes on a canvas, connecting them, and configuring each node's behavior — no code required for most use cases.
What you can build
- Customer support agents — route callers to the right topic, collect information, resolve issues
- Sales agents — run outbound campaigns with structured pitches and objection handling
- Appointment bookers — check availability, schedule meetings, send confirmations
- Survey bots — conduct phone surveys, collect and score responses
Key capabilities
| Capability | Description |
|---|---|
| Visual node editor | Drag-and-drop canvas with Agent, Provider, and Action nodes |
| Real-time testing | Make test calls directly from the editor before going live |
| Version control | Every publish creates an immutable snapshot. Roll back anytime. |
| Template library | Start from pre-built templates for common use cases |
| Prompt library | Write prompts once, reuse across multiple flows |
How it works
- Add nodes — place Agent nodes for conversation handling, Provider nodes for AI services, and Action nodes for side effects
- Connect nodes — draw edges to define how data and conversation flow between nodes
- Configure — set prompts, select models, define transitions between agents
- Test — run test calls to validate behavior
- Publish — lock the flow and assign it to phone numbers
