Call Copilot. Tell it what you want. A real Retell agent — with a real voice, a real phone number, real tools — gets provisioned live on the call. Or skip the phone and fill out the form. Same backend.
Pick up your phone. Tell Copilot what your agent should do, what voice, what to ask callers. It reads back a short URL while you're still on the line.
Answers instantly. Talk like you'd talk to a person. It's fast.
Same backend, same latency, no phone needed. You get a "Test my agent" URL the moment it's live.
By voice or by form, tell Copilot the agent's job, name, voice, greeting, and the questions it should ask.
A Lambda behind the Copilot tool hits Retell's REST API, creates a real LLM + Agent tuned to your spec, and mints a web-call access token.
Copilot reads back a short URL like /t/abxjm. Visit it, hit the call button, talk to your brand-new agent in-browser. No signup, no phone number purchase.
The Copilot itself is a Retell agent with a custom provision_agent tool. When you describe the agent you want, the tool calls the Lambda, which calls Retell's /create-retell-llm and /create-agent, stores a short-code mapping in DynamoDB, and returns a memorable URL the Copilot reads back to you. Same pipeline serves the web form. Every piece is something a Retell FDE would touch in their first month.
I'm Shanto Mathew — 12+ years of production Python, and for the last 2 years I've been shipping real voice + agentic-AI systems (Retell, OpenAI Realtime, LangGraph, function calling, sub-250 ms latency).
When I saw the Retell AI Forward-Deployed Engineer role I didn't want to send a resume and hope. I wanted to ship the kind of thing an FDE actually ships in the field — a working, production-lean Retell deployment that a customer could start using the moment I left the call.
So I built Retell Copilot: a voice agent (on Retell) whose one tool creates new voice agents (on Retell) on demand. Same developer experience I'd want a Retell customer to have. The whole system — voice prompt, Lambda, API Gateway, DynamoDB short-codes, the web companion, the Netlify edge — is in the public repo below. That's my cover letter.
