Build voice and chat agents that answer calls, make calls and reply to chats in Indian languages. Run them on-premise for full data control, or on VEXYL Cloud. Use any AI provider, plug into your own phone lines, and never get locked in.
Most voice AI platforms only run in their own cloud, on their own models. VEXYL gives you the choice.
Run the whole stack in your data centre or VPC. Air-gapped installs are supported with the standalone binary.
Sarvam, Google, Gemini, OpenAI, Groq, ElevenLabs, Azure, Deepgram, Ollama and more. Pick the best per language and per agent.
Prefer not to run servers? VEXYL Cloud runs it for you. Same platform, so you can move between the two.
Keep personal data in India or on your premises, with tenant isolation, role-based access and records you control.
Answer every call on your DIDs or PBX in the caller's language. Look things up, book, and hand over to a human with context.

VEXYL AI is an AI voice agent platform built in India. Agents answer and place phone calls and handle text chat, connected to your SIP trunk, Asterisk, FreePBX or business PBX. You can run it on-premise on your own servers or use VEXYL Cloud.
Yes. The VEXYL Voice Gateway and LiteBot run on your own servers. With the self-hosted VEXYL-STT speech recognition and a local model through Ollama, a call can be handled without audio or transcripts leaving your network.
VEXYL is built for the Digital Personal Data Protection Act, 2023: self-host it in India so personal data stays on infrastructure you control, choose India-region or fully local AI providers, isolate customers by tenant, restrict access by role, and keep conversation records in your own database so you decide retention and deletion. DPDP compliance also depends on your own consent, notice and grievance processes.
You are not locked in. Language models: Groq, OpenAI, Gemini, Vertex AI, OpenRouter, Sarvam and Ollama. Speech recognition: Sarvam, Google, Deepgram, Groq, Gemini and VEXYL-STT. Voices: Sarvam, ElevenLabs, Google, Gemini, Azure, Deepgram and Smallest. Switch per agent or per call.
Malayalam, Hindi, Tamil, Telugu, Kannada, Bengali, Marathi, Gujarati and more through providers such as Sarvam and Google, and 14 Indian languages on the fully self-hosted VEXYL-STT server.
Yes. Connect a SIP trunk from your carrier, Asterisk or FreePBX through AudioSocket or SIP, or an IP PBX such as Panasonic KX-NS, Avaya IP Office, Grandstream UCM or Bitvoice. There is no need to change numbers or carriers.
You pay AI providers directly at their rates, with no per-minute platform markup on self-hosted deployments. A live hospital deployment in Kerala runs Malayalam calls at about Rs 0.83 per minute all-in. The self-hosted Developer edition is free for up to 4 concurrent calls.
