Questions
Intervals and Retell AI, answered
What can start an automation from Intervals?
Any of Intervals's 6 triggers in the catalog, including New client, New invoice, New milestone and New person. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Retell AI when something happens in Intervals?
Any of Retell AI's 27 actions, including Create Knowledge Base, Create Retell LLM, Update Agent and Update Call. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Retell AI to Intervals?
Retell AI has no triggers in the catalog today, so automations start in Intervals. If you need the other direction, ask: your agent reads Retell AI's API documentation and adds it.
Do I have to build a connector for Intervals or Retell AI?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
