AI Call Prompt Generator (Retell AI, VAPI)
I built a free AI Call Prompt Generator for voice agents
Hey everyone 👋
I’ve been working on AI voice automation tools for a while now, and one problem kept coming up:
Writing good call scripts for AI agents is surprisingly hard.
Most people either:
overcomplicate prompts
or end up with robotic conversations
So I built a simple tool:

It helps you generate optimized prompts for:
AI cold calling
appointment booking
customer support
inbound/outbound agents

Make AI calls sound more human and actually convert.
Tech stack: Next.js + OpenAI + Redis
Right now it’s completely free.
Would love feedback from other builders here 🙌
What kind of AI workflows are you guys building?

Quick question — how long did it take you to build your UI?
I’m building Nexora to help founders skip that part (ready landing + dashboard).
Would love your thoughts on it 🙌
