The simple version
When someone calls a business number, Nixflex answers. It listens to the caller, understands what they need, replies in a natural voice, and takes action - all in about a second, in a real back-and-forth conversation. The same number can also reply to texts. You control what the agent says and does with a simple prompt; the engine handles everything else.Who it’s for
Businesses
Get a phone agent that answers calls, books appointments, and takes messages - without building anything. Ideal for clinics, salons, restaurants, and service businesses.
Developers
A voice AI API to embed phone agents into your own product. Bring your own Twilio, create agents, and go live with a few API calls.
Agencies
Run one agent template across many client numbers, each with its own bookings, CRM, and settings - all under one account.
Your own apps
Full control and the lowest cost, since you own the engine and the numbers.
What makes it different
- Real-time and natural - fast enough for a genuine conversation, not a clunky IVR.
- Bring your own Twilio - you own your numbers and carrier billing; Nixflex never marks them up.
- One number, voice and SMS - the same number answers calls and replies to texts, no separate chat bot.
- Live Monitor - listen to a live call from your phone or tablet.
- Integrations - book into calendars, push to CRMs, and connect thousands of apps, all per phone number.
