Hi Hacker News! I'm Prateek - I’ve been working on Bolna, an open-source platform for building end-to-end conversational voice agents.
With Bolna, developers can plug in their own LLMs, telephony systems, transcription models, and voice synthesis tools - and rapidly build apps that talk to users over phone calls or browser voice.
Why we built this
We originally set out to build an AI interviewer for practicing coding interviews - think Leetcode with voice. But we quickly realized that the orchestration layer (LLM ↔ telephony ↔ TTS ↔ ASR ↔ prompts ↔ logic) was the real challenge.
If this sounds interesting to you, please check us out! You can check us out our open source github repository at Github - https://github.com/bolna-ai or our hosted no-code/low-code dashboard at - https://platform.bolna.ai.
We’re inspired by open ecosystems like the Elastic stack and trying to follow a similar path: open by default, but easy to extend or host as needed.
