Proofreading · Free · In your browser
Have your draft read aloud in your browser to catch the run-ons, missing words, and clumsy phrasing your eyes glide right past.
A read-aloud proofreader uses your browser’s speech synthesis to voice your text so you can hear errors instead of only seeing them.
Your browser can't read text aloud here.
This browser doesn't support the Web Speech API (Firefox on Android is the usual culprit). You can still use the pre-scan below to spot long sentences and repeated words, or try the other cleaning tools in Chrome, Edge or Safari.
Your ear catches what your eyes skim. Try a flawed sample:
0 words · 0 sentences
Things to listen for
How to use: pick a voice → press Play → as you hear an off line, tap 🚩 Flag (or press F) → fix the whole list at the end. Space plays/pauses · ←/→ jump sentences · R re-hears.
🔒 With a local voice this runs entirely on your device - nothing is uploaded. Works offline.
The short version
There is no server and no upload. Everything runs with plain JavaScript on your device, so you can safely work with confidential or unpublished text. Open your browser's DevTools Network tab while you use it and you'll see zero requests - and it keeps working with your connection turned off.
In the margin
Your eyes autocorrect familiar text, so you read what you meant to write. Hearing it forces every word to register, which surfaces missing words, doubled words, and sentences that run on too long.
It uses your browser’s built-in speech synthesis, which runs on your device. Availability of voices depends on your browser and OS, but no text is sent anywhere.
No. Everything runs in your browser with plain JavaScript - your text is never uploaded, stored, or logged. Open your browser’s DevTools Network tab while you use it and you’ll see zero requests. The tool also works offline.
Margin note
Every tool here runs 100% in your browser. Open DevTools → Network while you use one and you'll see zero requests - your text never leaves your device. Prefer the deep dives? Read the writing on Penluma.
