Inbound lead qualification has never been smoother!
Great voice quality, though occasional lag on complex prompts.
Automated outbound reminders cut our no-show rate by half.
Pricing gets expensive once call volume scales up.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Agents answer calls around the clock, capture lead details, qualify enquiries and route callers to the right person or department.
Run follow-up calls, collect missing documents or payment reminders at scale, with multi-channel SMS and email alongside the voice call.
Agents book, cancel and reschedule appointments in real time, tying the booking step directly to the call that generated it.
Every conversation produces a transcript, summary and analytics so managers can review what was asked and how it was handled.
Support customers in the language they choose, choose from a library of premium voices, and plug into existing CRM and call-centre systems.
Curious Thing provides plug-and-play voice AI agents built for organisations that live on the phone. The platform ships with named assistants for different jobs: Lucy answers inbound calls and summarises them by text, Alex handles FAQs and qualifies inbound leads while booking, cancelling or rescheduling appointments and routing calls to the right person, and Sam and Lou run outbound campaigns for follow-ups, document retrieval and payment reminders. A custom agent option lets teams tailor the persona and workflow to their own industry.
Beyond the agents, the platform focuses on operational scale: it can handle anything from 100 to 100,000 calls, sends SMS and email before, during or after a conversation, supports multilingual voices, integrates with existing CRM and call-centre stack, and produces call transcripts, summaries and insights in real time. Curious Thing reports having processed millions of minutes of AI-human conversations and publishes customer stories in fintech, financial services and non-profit counselling.
Pricing follows a freemium structure: businesses can start on a free tier and move to paid plans as call volume and feature needs grow. The vendor emphasises global privacy and security standards, citing ISO 27001, SOC 2, GDPR and HIPAA compliance, which matters for regulated sectors such as finance and healthcare. As always with voice AI, call quality and latency depend on the deployment and the telephony setup you connect.
Cover overflow and after-hours enquiries so callers get an answer immediately instead of waiting for a human or dropping off.
Capture lead details, answer common questions and book qualified prospects directly into the calendar during the first call.
Reach customers about upcoming payments, missing documents or incomplete applications without adding headcount.
Deploy in finance, healthcare or counselling settings where ISO 27001, SOC 2, GDPR and HIPAA alignment is a procurement requirement.
