Build interactive onboarding flows and forms that capture and convert leads
Assemble multi-step flows with a drag-and-drop editor, adding question types, content blocks, and branching rules without writing code.
Use conditional logic to route each visitor down the path that fits their answers, so the experience feels tailored rather than one-size-fits-all.
Embed flows as website widgets or run them as standalone pages to capture leads, run qualification quizzes, and gather feedback.
Add progress indicators and interactive touches that keep respondents engaged through longer onboarding journeys and improve completion rates.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
