About

Quick TTS exists because every other free text-to-speech tool either caps you at 1,000 words, makes you sign up, or tries to upsell you into a subscription. This doesn't.

What it is

Quick TTS is a single-page web app that takes whatever text you paste and reads it aloud in your browser. No account. No character cap. No watermark. No "upgrade to continue." Just a text box, a play button, and a voice.

Under the hood there are two speech engines:

• Your browser's built-in voice (the Web Speech API), which works everywhere — desktop, mobile, even in a pinch on older systems.
• AI Voice, an optional neural TTS model called Kokoro that runs on your GPU via WebGPU for a dramatically more natural read. Desktop Chrome/Edge only for now.

Why it's free

Running the site costs roughly the price of a coffee per month (static hosting on Firebase, a domain registration, nothing else). Display ads from Google AdSense cover that cost and — if this takes off — eventually some of the time that goes into building and maintaining it.

There is no paid tier planned. There is no "premium voice" locked behind a paywall. The AI Voice feature is free for the same reason the default is free: it runs on your machine, not ours, so it doesn't cost us anything to offer it.

Design principles

A few rules we're trying to hold to:

• Your text stays on your device. All synthesis happens client-side. We never receive your text and we never will.
• No sign-up. The moment a tool demands an account for a 30-second interaction, it has failed.
• No dark patterns. Ads are display ads in fixed slots. No pop-unders, no interstitials, no "wait 15 seconds before your audio plays," no fake download buttons.
• Transparent about limits. The only thing that can't be synthesized is text too long for your browser to hold in memory. If something doesn't work, the reason is in the FAQ.

Built on open tech

Quick TTS wouldn't exist without a few brilliant pieces of open-source work:

• Kokoro-82M — the neural TTS model powering the Kokoro HQ option (Apache 2.0).
• Piper by rhasspy — the universal neural TTS that powers the Piper option (MIT). Voice models from rhasspy/piper-voices: we ship a curated set under CC-BY 4.0 (LibriTTS-R, VCTK) and CC0 / public domain (Joe). License details are listed in each voice's MODEL_CARD on the piper-voices repo.
• Transformers.js — the library that lets ML models run in the browser.
• vits-web — the WASM bindings for VITS-family models that make Piper run in browsers.
• The Web Speech API — quietly shipped in browsers for over a decade, still the unsung workhorse.

Who built this

Quick TTS was built by a small team at Next Now Agency as a sister project to WSBSynth, a real-time r/wallstreetbets comment reader. Most of the TTS architecture is shared between the two — WSBSynth was the proving ground, Quick TTS is the consumer-friendly version.
