Operate Windows apps with AI, from chat to API to SDK
Pig Chat connects your machines and lets you prototype automations through a conversational interface, no code required.
The Agent API exposes the same computer-use AI behind Pig Chat so you can launch tasks from your own services.
A low-level SDK provides the base toolkit for building custom agents, using natural tools like click(), type(), and screenshot().
Agents control the screen the way a person would, transferring control to a human operator for critical steps and picking it back up afterwards.
Build, test, and deploy production-grade voice AI agents over API
Configure speech recognition, an LLM reasoning layer and text-to-speech through one API instead of integrating several vendors separately.
The platform handles real-time audio streaming, interruption handling and call state so conversations feel natural and responsive.
Provision Vapi phone numbers or bring Twilio, Vonage or Telnyx, and support both inbound and outbound calling from the same agent.
Simulate calls before launch, then track transcripts, effectiveness metrics and compliance signals across every production call.
