It comes down to whether you want trained human agents on every call, or a flat-rate, multilingual AI that's live fast.
Smith.ai built its reputation on putting trained humans on the line, and for firms that need that, it's a genuinely strong choice. But many service businesses don't need a human on every call — they need every call answered, instantly, at a price they can plan around. That's where iSada fits: flat pricing from CA$69/month, no per-minute surprises, and a pure-AI receptionist that answers 24/7.
iSada is a flat CA$69 (Business) or CA$139 (Pro) per month — not per-call or per-minute. You get predictable costs whether you take 20 calls a month or 2,000. See the full breakdown on our pricing page.
iSada detects and responds in 40+ languages automatically mid-call, so multilingual customers get the same seamless experience without you staffing for it — a key advantage if your callers don't all speak English.
iSada doesn't just take a message — it checks your calendar, books the appointment, and sends an SMS confirmation. It's trained on the bookings, questions, and edge cases specific to your business.
