Scheduling and meetings decision

Setter AI LLC

A technical user can build a useful self-hosted flow that auto-responds to leads and books Calendly meetings (minimal replacement), but replicating Setter AI's claimed conversion performance, language coverage, operational reliability, and onboarding/managed services is costly and time-consuming.

No open-source build does this yet

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.

What a replacement has to do

  • Receive lead → send instant message via WhatsApp/SMS → qualify via LLM-based dialog → create booking in Calendly → store lead and conversation

What it still won’t have

  • Proprietary prompt engineering and any internal training that optimizes their quoted 15–52% booking rates
  • Enterprise onboarding, account-management, and done-for-you integration services
  • 24/7 support, uptime and operational monitoring offered by the vendor's hosted service
  • Wide-language production support and claimed 113+ language coverage out of the box
  • Any built-in phone/WhatsApp number provisioning or regional exclusivity features

What remains hard

  • Product polish and ongoing maintenance

Runnable build prompt

Not run yet
Build a minimal self-hosted AI appointment setter using Node.js (Express) backend, Postgres DB, a background worker (BullMQ), OpenAI (chat completions) for conversational qualification, Twilio (or Meta/WhatsApp Business API) for WhatsApp/SMS messaging, and Calendly API for booking. In scope: webhook endpoints to receive leads, connectors to send/receive chat messages, LLM-powered dialog flow with templated prompts and fallbacks, Calendly booking creation and confirmation messages, Postgres storage for leads/conversations/bookings, a simple admin UI to view leads and booking status, and a worker to send scheduled follow-ups/reminders. Out of scope: multi-tenant billing, advanced analytics dashboards, custom enterprise regional exclusivity, and language model training. Include error handling for provider failures, rate limits, retries, exponential backoff, and unit/integration tests for webhooks, message flows, and booking operations.
