A voice AI platform and a finished receptionist solve different problems. Three questions show which one a business needs.
A platform gives you the parts: voices, a flow builder, an API. Someone has to design the conversation, connect the booking system and keep it working. Solwees is a finished receptionist that you set up in a dashboard.
On a platform, writing a booking into your system is an integration you build or configure. Solwees connects to the booking systems it works with, and books there.
Platforms usually charge by usage, per minute of a call. Solwees charges per location per month; phone minutes come with the Studio plan or in packs that do not expire.
Solwees answers phone calls, WhatsApp, Instagram, Telegram, Messenger, website chat and email around the clock, in 50+ languages. Every conversation lands in one inbox that the team opens on the web or in the mobile app.
The assistant books appointments and reservations into your booking system and sends reminders. Solwees works on top of the system you have and does not replace it. A business without a supported system can take bookings into the calendar of Solwees itself.
Vapi is the better choice for a developer or a product team that wants full control of a voice agent: which transcriber, which language model, which voice, what happens at each step. It offers an API, SDKs for web and mobile, outbound campaigns and a separate EU region. The calculator on its pricing page shows $82 to $129 for 1,000 minutes with its default providers.
Solwees is the better choice for a business owner who wants calls and chats answered without writing code. The assistant is set up in a dashboard: the booking system, the channels, the knowledge base. It answers in WhatsApp, Instagram, Telegram and Messenger as well as on the phone, and books into salon and restaurant systems through ready connectors.
7 days, no card. The whole platform is open, with up to 100 active clients and 20 call minutes.
Choose it in the list of integrations. From then on the assistant books into the system your team already works in.
WhatsApp, Instagram, Telegram, Messenger, website chat and email, plus a phone number if the assistant should answer calls. Fill the knowledge base with your services, prices and rules.
Try the assistant on one channel or one location first. Move the rest when you are satisfied, and cancel what you no longer need.
Vapi is a developer platform: you assemble a voice agent from a transcriber, a language model and a voice, configure its tools and connect it to your systems. Solwees is a finished AI receptionist and booking software: one assistant answers calls, WhatsApp, Instagram, Telegram, Messenger, website chat and email for a service business and books into the booking system it already uses.
Vapi, as of October 2026, charges $0.05 per minute for the platform itself plus speech-to-text, the language model and text-to-speech at the providers’ prices; the calculator on its pricing page shows $82 to $129 for 1,000 minutes with its default providers. Solwees charges per location per month: €99 for the assistant in chats, €249 with phone answering and 100 call minutes, and minute packs from €39 for 100.
Vapi says it focuses on developers. A first agent can be made in its dashboard without code. Its documentation says that more advanced features, such as calling your own functions, need a server on your side. A service without a prebuilt tool is connected through an API request, MCP or function tool that you configure. Solwees is set up in a dashboard: you connect the booking system and the channels and fill in the knowledge base.
The Vapi documentation lists phone calls, a web widget with text chat and voice, a chat API and SMS on US numbers as its channels. WhatsApp, Instagram, Messenger and Telegram are not among them. Solwees answers in all four with the same assistant that answers the phone, and keeps the conversations in one inbox.
Vapi has prebuilt tools for Google Calendar and GoHighLevel that check availability and create bookings. For any other system its documentation describes an API request, MCP or function tool that you configure yourself. Solwees works with Altegio, Booksy and Fresha for salons and with SevenRooms, OpenTable and CoverManager for restaurants, with nothing for you to develop.
