02Why Inspra
What you can do with Inspra.
Start with an idea, not code
Describe what you want your Inspra Agent to do in plain language. Inspra Copilot prepares a starting configuration for you to review, helping non-technical teams get started quickly. Test the agent before launch; custom tools and integrations may need technical help.
Inspra — CopilotMake your dispositions visible
Add the dispositions your team uses and see them on the dashboard. For example, define business outcomes such as “Appointment booked”, “Follow-up required” or “Not interested” to match your operation. These are illustrative labels, not a claim about default categories.

Inspra — automation flows
Give your team a shared view of the outcomes that matter
A useful comparison goes beyond whether a platform can extract a value from a call. In Inspra, you can add your own dispositions and make them visible on the dashboard, alongside the client operations your team manages. Vapi and Retell also provide analysis capabilities, so evaluate the complete setup: how an outcome is defined, where it appears, who can access it and how the team acts on it. These are Inspra capabilities, not a claim that every feature is exclusive.
