Ship realistic text-to-speech
inside your app.

Wfloat makes speech AI that runs on-device instead of in a data center.

Pay by user count, not usage fees.

    What is it for?

    Wfloat is for businesses that want to give their AI a voice at scale. It's made for AI powered games, assistants, agents, tutors, and more.

    We train and distribute lightweight, lifelike speech models that are small enough run on consumer devices. Rather than chasing frontier model capability, we are zeroing the cost of speech AI at inference time.

    In doing so, we will help power this next generation of immersive AI driven apps and products.

    AI Powered Games

    You
    I push open the stone door and step into the flooded hall. What do I see?
    Guide

    Cold water ripples around your boots. Broken banners sway overhead, and something heavy shifts in the dark beyond your lantern.

    Scout

    Left passage. Fresh mud on the stone, and whatever dragged it there is still close.

    Keeper

    Then keep your voice down. This hall listens, and the idol below wakes for frightened guests.

    Warden

    Then the surface splits. A brass eye rolls open below you and fixes itself on your lantern flame.

    How does it work?

    It's easy, just install the Wfloat package into your frontend app ( takes 5 minutes ).

    From there, Wfloat automatically serves the correct speech model assets directly to your end users.

    Pricing is different and competitive compared to other speech AI platforms. We don't charge you anything for how much speech audio your users generate. In other words, inference is free.

    We charge a small monthly fee for each active user of text-to-speech. For details on cost or how we define an active user, see the pricing page .

    What hardware do my users need to run it?

    It runs on basically any phone, laptop, PC, or tablet from the last decade.

    • Expect near real-time performance on modern phones, tablets, and laptops.
    • Expect about a 2 second time-to-first-audio delay on a 2017 iPhone 8 or Galaxy S8.

    If a user can comfortably run a modern website or mobile app, they will be in good shape here too.
