This comes up enough that it’s worth addressing directly. Someone hears about an AI that answers phone calls for small businesses and their first reaction is: doesn’t my phone already do something like this?
It’s a reasonable question. The short answer is no, but the confusion makes sense because both Siri and Clara involve phones and AI, and the overlap ends there.
What Siri does
Siri is a personal assistant that lives on your phone. It can set reminders, send texts, play music, and answer questions. When it comes to phone calls, Siri can screen calls, read out who’s calling, and let you send a canned response like “I’ll call you back.” On newer iPhones, it can transcribe voicemails in real time so you can see what someone’s saying without answering.
These are genuinely useful features. But they’re designed for the phone’s owner, not the caller. If a plumber’s phone uses Siri to screen a call, the caller still gets voicemail. The experience on their end hasn’t changed at all.
What’s different
Clara answers the call and has a conversation with the person on the other end. It asks questions that the business owner has configured — what’s the problem, where’s the property, is it urgent, what’s your contact number. The caller speaks, Clara responds, and by the end of the exchange the caller has described what they need and given their details. The business owner gets a summary.
The difference isn’t technical sophistication. It’s which side of the call is being served. Siri helps the business owner manage their phone. Clara helps the caller get a useful response when the business owner can’t pick up.
Why this matters
Invoca’s research shows that less than 3% of callers leave a voicemail. That number doesn’t change if the voicemail is transcribed by AI or delivered by a smarter notification. The caller’s experience is still: I called, nobody answered, I’m talking to a machine that isn’t talking back. Whether that machine is slightly cleverer on the business owner’s end doesn’t affect their decision to hang up and try somewhere else.
Mark, a plumber we’ve spoken to, described his old setup: iPhone with voicemail transcription turned on. He could see what people were saying without listening to the messages, which saved time. But the callers still weren’t leaving messages. “The transcription was great for the ones who left a voicemail,” he said. “The problem was that hardly anyone did.”
The actual comparison
A fairer comparison for Clara isn’t Siri. It’s a human receptionist. Both answer the phone, both have a conversation with the caller, both capture details and pass them along. The difference is cost, availability, and consistency. A receptionist costs money, works limited hours, and has good days and bad days. Clara answers every call the same way, at any time, for a fraction of the price.
Whether that’s the right trade-off depends on the business. Some people genuinely prefer having a human answer their phone, and that’s a legitimate choice. But the comparison with Siri is a category error. Siri makes your phone smarter. Clara makes your phone line available.
