Introduction to Inspra

Build AI voice agents that make and receive phone calls, help customers, and take action in your business systems.

What is Inspra?

Inspra is an AI voice agent management platform. You create agents, give them instructions and approved knowledge, choose how they speak, and connect them to phone numbers. Your team can run outbound campaigns, review conversations and measure results from one workspace.

Agencies can manage separate client workspaces and offer the platform under their own branding and domain. Each workspace keeps its agents, calls, campaigns, knowledge and team configuration together.

How voice agents work

Listen: speech-to-text turns a caller's speech into text.
Understand and act: a language model follows the prompt, consults approved knowledge and uses configured tools.
Speak: text-to-speech turns the response into the selected voice.
Review: Calls brings together the transcript, recording and configured analysis after the conversation.

Provider settings determine the available models, voices and tools. You can create an agent on Inspra Agent, Vapi or Retell; its provider is fixed after creation.

Knowledge: create documents, upload files or import website content, then attach approved information to an agent.
Campaigns and messaging: call recipient lists with scheduling controls, manage SMS and WhatsApp, and build automation flows when enabled for your workspace.
Quality and reporting: run agent tests, review recordings and transcripts, and configure outcomes, scorecards and structured outputs.

Your workspace's plan, permissions and connected services determine which controls are available.
