AI Concierge — Comparison
Smith.ai vs FilterMyCalls: Per-Call AI vs Flat-Fee AI Concierge
Both are AI-first answering services with strong reputations. The real difference is the pricing model — per call versus flat fee — and it flips the winner depending on how much your phone rings.
Smith.ai's AI Receptionist starts at $95/month for roughly two calls a day, with $2.40 per call beyond your plan. FilterMyCalls charges a flat $349–$699/month for unlimited inbound. So the math is simple: light volume favors Smith.ai's low entry price; steady volume favors FilterMyCalls' flat fee.
Beyond price, the difference is shape: Smith.ai pairs AI with live-agent backup and bills per call; FilterMyCalls is a flat-rate platform with a multi-line dashboard and audit log built for practices that want one predictable number.

Our pick
If your phone rings steadily, FilterMyCalls' flat fee almost always costs less than Smith.ai's per-call model once you clear roughly a handful of calls a day — and the bill never moves.
Best for: Multi-line practices and any business with consistent daily call volume that wants one predictable price.
Not for you if: Your call volume is genuinely low or spiky — Smith.ai's $95 entry plan will likely cost less, and you only pay for the calls you get.
