Most voice AI platforms sell you a voice API. OpenVoiceUI gives you an entire AI workspace — voice, canvas, skills, agents, media generation — open source and self-hosted.
Voice AI platforms like Vapi, PlayAI, Bland, and ElevenLabs are great at what they do — voice synthesis and phone call automation. But if you need an AI that does real work beyond talking, you hit their walls fast. OpenVoiceUI was built for the full picture: voice conversation plus a visual workspace where your AI builds dashboards, generates images, writes reports, and remembers everything.

Key Differentiators
The features that make OpenVoiceUI a different category entirely.
Other platforms give you a voice API. OpenVoiceUI gives you voice, a visual canvas, file management, media generation, scheduled tasks, and a memory system — all in one interface your users actually interact with.
Self-host on your own infrastructure. No API calls routed through third-party servers, no vendor lock-in, no surprise billing. Connect any LLM, TTS, and STT provider you choose.
The skill system lets you add capabilities without touching core code. 35+ built-in skills cover social media, SEO, email, reports, and more. Build custom skills for any workflow.
MIT licensed. No per-minute charges, no seat fees, no usage caps. Pay only for the LLM and TTS providers you choose to use — at their direct pricing, not a markup.
