The fastest way to build
on Retell AI.
Stop stitching Retell with n8n, ElevenLabs, and custom APIs. Describe your receptionist and Tendo AI delivers a fully configured Retell agent — voices, tools, and integrations included.
Functions wired automatically
Every tool your receptionist needs — booking, pricing lookups, CRM logging — is created and attached to your Retell agent without manual JSON or webhook setup.
Prompts tuned for voice
Tendo AI writes receptionist prompts optimized for phone conversations: concise answers, natural turn-taking, and guardrails that keep agents on-script.
Your account, your agent
The finished agent lives in your Retell AI dashboard. You own the phone numbers, call logs, and billing relationship with Retell — Tendo just eliminates the build work.
How it works
Four steps from idea to live AI receptionist.
Describe your receptionist
Tell Tendo AI what the agent should do — book appointments, answer FAQs, route calls.
Connect your tools
Pick integrations like Square, Calendly, or HubSpot. Tendo wires the APIs and functions automatically.
Deploy to Retell AI
Tendo selects a natural voice, writes the prompt, and places the finished agent in your Retell account.
Start taking calls
Attach a phone number in Retell and your AI receptionist is live — no debugging workflows required.
