Smith.ai vs AgentClara: Which Fits a UK Business?
The short answer: Smith.ai is a strong US-based service combining AI with North American human receptionists, priced in dollars with per-call billing — excellent for US firms, especially law practices. AgentClara is UK-built, AI-first, priced in pounds, and self-serve: live in minutes with a free number and £100 of credit. For a UK service business, the practical differences are currency, accents, setup and billing model.
What Smith.ai does well
Credit where due: Smith.ai is one of the most established names in the category, pairing an AI receptionist with a large team of trained human receptionists, and it's particularly strong for law firms thanks to deep integrations with legal practice-management tools. Credit where it's due on pricing too: as of 20 August 2026 their AI Receptionist has a genuinely free tier — $0/month for 25 calls, with AI scheduling and native integrations included — so you can test it without talking to anyone. If you're a US practice that wants humans in the loop, it's a serious option.
