What our research says

Betula Assistant

Betula answers a specific small-business pain point, missed calls and unfiltered spam eating into a workday, by putting an AI receptionist on its own number that also remembers prior conversations. Per-minute billing on top of a small base fee makes the real monthly cost hard to predict until you know actual call volume.

Pros

  • Gives the business a dedicated phone number rather than routing an existing line
  • Filters spam calls before they reach a person
  • Joins meetings to take notes in addition to handling calls
  • Remembers prior conversations and commitments across calls

Cons

  • Per-minute pricing makes total monthly cost hard to predict upfront
  • Service area is currently limited to the US and Canada
  • Higher-volume Growth tier requires contacting sales rather than self-serve signup

Rosie

Rosie fits small businesses that lose real revenue to missed calls and want a receptionist that never sleeps, without hiring one. It's self-funded and priced per-minute-bucket, so a business with unpredictable call volume needs to watch which tier they land in.

Pros

  • Trains itself from the business website and Google Business Profile
  • Direct calendar booking and call transfers on higher tiers
  • Every call comes with a recording, transcript, and summary
  • Free website chat widget included on all plans

Cons

  • Minutes are capped per tier; heavy call volume forces an upgrade
  • Only bilingual (English/Spanish), not broader multilingual support
  • Higher-tier features like priority transfers and white-glove onboarding are gated to the $299 plan
