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.
Synthflow is the better choice for a company that runs phone lines at scale and wants to design its own agents: a BPO, a contact centre, an agency with sub-accounts for its clients. It offers a visual flow designer, its own telephony, AI on WhatsApp voice calls and a choice of US or EU data region, and its engineers take part in enterprise rollouts.
Solwees is the better choice for a salon, clinic or restaurant that wants calls and chats answered and bookings made without a project. The prices are published, from €99 a month per location, and the trial is free for 7 days. The assistant also answers in Instagram, Telegram, Messenger and by email, and works with salon and restaurant booking systems.
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.
Synthflow is a platform for building voice and chat agents: an enterprise team designs the call flows in a no-code builder and connects its own systems. Solwees is a finished AI receptionist and booking software for service businesses: one assistant answers calls, WhatsApp, Instagram, Telegram, Messenger, website chat and email, and books into the booking system the business already uses.
Synthflow shows no per-minute price on its pricing page. As of October 2026 that page says enterprise contracts start at $30,000 a year and that the final price is agreed with sales. Solwees publishes its plans: €99 a month per location for the assistant in chats and €249 a month with phone answering, 100 call minutes and outbound calls. The trial is free for 7 days.
Synthflow works with WhatsApp in two ways, according to its site and documentation. AI answers WhatsApp voice calls, and chat agents can reply to WhatsApp and SMS text through the customer’s own telephony provider account, on US-region workspaces only. Its channel documentation does not list Instagram, Messenger or Telegram. Solwees answers WhatsApp, Instagram, Telegram and Messenger messages with the same assistant that answers phone calls.
The Synthflow documentation describes a real-time booking action for Cal.com and GoHighLevel calendars, and its integrations page lists Google Calendar, Jobber, Housecall Pro and ServiceTitan among 200+ tools. That page lists no salon software or restaurant reservation systems. Solwees works with Altegio, Booksy and Fresha for salons and with SevenRooms, OpenTable and CoverManager for restaurants.
Synthflow suits an enterprise, a BPO or an agency that wants to build and run its own voice agents on many phone lines, with a visual flow designer, in-house telephony, sub-accounts and a US or EU data region. A single service business that wants bookings taken on the phone and in messengers, at a published monthly price, is the case Solwees is made for.
