Why teams choose Keres over Ruby
Ruby offers friendly human virtual receptionists, but coverage is tied to staffed hours and minutes you pay for. Keres answers every call 24/7 with AI, books the appointment during the call, and runs at a flat monthly rate — so nights, weekends, and call spikes are covered without per-minute charges.
Keres AI is an alternative to Ruby for businesses that need a done-for-you AI receptionist: it answers every call 24/7, books appointments on your calendar, integrates with field-service software, and charges flat-rate pricing — rather than per-call or per-minute fees.

The key difference
The difference isn't just features — it's the model. Keres is built as a done-for-you AI receptionist: we map your call flows, integrate your calendar and field-service stack, train the AI on your business, and launch in five business days. You don't build a bot; you get a front desk. The AI answers every call, books every job, and escalates every emergency — without you touching the configuration after go-live.
