Ease of Setup and Deployment
Thoughtly prioritises speed. A small dental clinic, for example, could launch Thoughtly in a single afternoon, setting up a virtual receptionist to book appointments and handle common patient questions. No IT team required. Vapi requires coding. A startup building a telehealth SaaS platform might choose Vapi, but they’d need developers to connect it to scheduling software, patient records (EHR/EMR), and custom call flows before it becomes usable for medical triage or emergency routing. If you want something running by tomorrow, Thoughtly is the clear winner. If you want to build a tailored solution over weeks or months, Vapi gives you the flexibility.
Customization and Voice Quality
Thoughtly offers a curated set of professional, multilingual voices that are ready to go through their voice library. You can also clone your own voice via Cartesia. A boutique salon could set it up to sound friendly and professional without worrying about scripting every detail. Vapi allows full customization. You can also select from their list of voices. For example, a luxury hotel chain might use Vapi to create a branded AI voice agent that greets callers with a specific accent, incorporates signature phrases, and adapts tone depending on the type of guest. Both platforms provide access to polished, natural-sounding voices and allow for a degree of customisation. The difference lies in how much control you want.
Integration Capabilities
Thoughtly focuses on prebuilt integrations with tools like Zapier and Pabbly, CRMs, calendars, and messaging apps, which can be synced without a developer. For example, a law office could sync Thoughtly with its CRM to log new client calls automatically, without needing a developer. Vapi provides the APIs to connect to almost anything, but you have to build it. A SaaS company could use Vapi to integrate with a proprietary customer portal, but only if they have developers to stitch the systems together. If you’re already using standard business tools and want plug-and-play connectivity, Thoughtly works well. If you’re running custom infrastructure or want AI voice deeply embedded into your product, Vapi is the better choice.
Performance: Latency and Reliability
Thoughtly designed for real-time responsiveness. A small retail shop using Thoughtly won’t have to worry about customers waiting awkwardly between responses. Vapi can perform just as well, but depends heavily on how it’s implemented. A SaaS platform could fine-tune Vapi for speed, but that requires engineering work. If you want low latency without tweaking, Thoughtly is ready-made. If you’re comfortable optimising, Vapi gives you the tools.
