I built an AI receptionist for plumbers. Call the demo line and try to break it

I’m a CS student and since August I’ve been building CallsIn by myself. It’s for small home service businesses, the 1 to 10 truck plumbers and HVAC shops where the owner is also the guy under the sink. When they miss a call, the caller gets a text from the business within seconds. On the bigger plans an AI answers the phone 24/7, asks what’s wrong, and books the job on their calendar. Real emergencies get transferred to the owner live. You can call the demo line right now: (447) 225-5746.

AI 分析

痛点:小型水管/暖通维修商漏接电话会直接丢单,老板常亲自上门干活,无法兼顾接听和预约。

目标用户:1到10辆车的家庭服务小企业主,尤其是水管工和HVAC店主,老板本人也是一线技师。

证据:When they miss a call, the caller gets a text from the business within seconds. On the bigger plans an AI answers the phone 24/7, asks what’s wrong, and books the job on their calendar. Real emergencies get transferred to the owner live. / 1 to 10 truck plumbers and HVAC shops where the owner is also the guy under the sink.

变现:按月订阅分层收费:基础套餐漏接短信,高级套餐AI接听、预约、紧急转接;可按通话分钟数或坐席数加收费用。

MVP:2周内用Twilio/Vapi或Retell加OpenAI Realtime,再接入Google Calendar API,做出漏接触发短信、AI接听问故障、查可约时段并预约、紧急关键词转接老板的最小闭环,先找本地水管工试用。

竞品:Avoca、Goodcall、Smith.ai、Rosie、Slang.ai

摘要:CS学生独自开发CallsIn,面向1-10台车的水管和HVAC小企业,漏接电话几秒内发短信,高级套餐用AI 24/7接听、问故障、预约并转接紧急情况。帖子提供演示电话和网站,但未披露客户数、收入或用户付费证据。该赛道已有多个AI接线员竞品。
