Building in Public
From the Butter AI team
We built Butter AI because we were frustrated with existing voice AI platforms that lock you into one provider and charge absurd markups on top of already expensive API costs.
Butter is different: true multi-provider flexibility (mix GPT-4, Claude, ElevenLabs, Deepgram—whatever works for you), transparent pass-through pricing, and powerful enterprise features like vector-based knowledge bases and custom API tools. We're in early access right now, working closely with our first users to make this platform exactly what businesses need.
Want to be part of the journey? Early adopters get preferential pricing, direct access to our team for feature requests, and the chance to shape where Butter goes next.
