OnCallClerk is an AI phone answering platform for small and medium businesses. When someone calls, an AI agent picks up, answers questions about the business, captures the caller's details, books appointments, and sends the owner a transcript and summary.
The company says it built the product because many small businesses lost calls and revenue without a full-time receptionist or a traditional answering service. It positions itself against voice AI tools it considers too expensive or aimed at developers, and says it needs no code, no API integration, and no onboarding calls.
Setup runs through a guided wizard. You pick your industry, and the template pre-fills pricing and common answers. You then choose one of 30+ voices, set hours, escalation, and forwarding rules, and claim a local or toll-free number or forward your existing line.
After you go live, the agent answers each call, holds a conversation, and records details such as caller name, issue, and urgency. Every call is transcribed and summarized, then sent to your inbox or CRM. Urgent callers can trigger instant alerts so the right person is reached.
The core feature is 24/7 answering that handles many calls at once, so callers do not wait on hold. The agent books appointments in a connected calendar, captures leads, triages urgent calls, and produces searchable transcripts with short summaries. It works in English and Spanish without extra setup.
Industry tuning is a second focus. Scripts, vocabulary, and urgency rules cover 18 industries, from plumbing and HVAC to real estate and property management. For technical teams, the platform exposes a REST API and a TypeScript SDK, and agencies can resell agents under their own brand.
