About PostTTS
A simple, honest text-to-speech service for publishers who want to give readers the choice to listen.
What we do
PostTTS turns article text into natural-sounding audio. Publishers add one script tag (or install our WordPress plugin, or call our REST API), and every article on their site gets a play button. Readers can listen while they commute, exercise, or multitask.
Why we built it
Audio is the fastest-growing content format on the web, but most tools require publishers to copy each article into a separate tool, manage audio files manually, and maintain a custom player. We wanted something that just works: paste a script tag, and your articles become listenable.
We also wanted to keep pricing honest and predictable. The free plan covers personal blogs. Paid plans scale with real usage, not arbitrary "seats" or locked features.
How it works under the hood
- Your article text is converted to audio using a text-to-speech engine and stored as an .m4a file.
- The embed script is plain JavaScript (~10 KB gzipped, zero dependencies) and loads with
deferso it never blocks your page. - Audio files are served from Cloudflare's global CDN so playback is fast anywhere.
- The WordPress plugin is open source (GPLv2) and ~14 KB. You can read every line of it.
Our commitments
- No tracking. We use a single session cookie for login. No third-party analytics or ad pixels.
- No AI training on your content. We process your text only to generate the audio you asked for.
- Transparent billing. Clear usage limits, no surprise overages, cancel anytime.
- Open source where we can. Embed script (MIT) and WordPress plugin (GPLv2) are open for you to read, audit, and self-host.
