Private, free text-to-speech that reads along with you
Read Aloud turns any text into natural spoken audio right inside your browser. It is built for the everyday jobs a good reader should handle: proofreading your own writing by ear, following along with an article while you do something else, learning how unfamiliar words sound, or making written material accessible. Because the speech is generated on your device, the text you paste is never uploaded, there is no account to create, and there is no per-character cost — read as much as you like.
Two voice engines, one simple reader
System voices use the speech engine already built into your operating system, so they start instantly and cover dozens of languages — pick a language to filter the list, then choose a voice. As they speak, each word is highlighted in the read-along panel and the view scrolls to keep up, so it is easy to follow on screen. You can click any sentence to start reading from exactly that point. The second engine is an on-device AI neural voice: it downloads a small model once and then runs offline, giving a consistent sound across devices and — crucially — letting you save the result as an audio file.
Control the delivery
Speed, pitch and volume are all adjustable, with live values so you can dial in a comfortable pace. Three one-tap presets cover the common cases — Normal for general listening, Proofread for a slow, careful pass over your own draft, and Speed-listen for getting through long text quickly. Pro lets you save your own named presets, so a “study” pace or a “bedtime” voice is always one tap away.
Built for longer reading and accessibility
For names, brands and acronyms that text-to-speech engines mispronounce, the Pro pronunciation dictionary applies “read as” replacements automatically, right before the text is spoken, without altering your original copy. Pro file import opens .txt and .pdf documents straight into the reader, the document library keeps the texts you return to, and MP3 plus whole-document export let you turn a long article into an audio file you can keep. Everything still runs on your device — a genuinely private alternative to cloud readers that meter characters or stamp watermarks.
Yes — the reader is free and unlimited. Type or paste any text and hear it in dozens of voices with read-along highlighting and speed control, no signup and no character cap.
Does my text get uploaded to a server?
No. System voices use your browser's built-in speech engine and the optional AI voice runs on your device, so the text you read is never sent anywhere.
Why are there two voice engines?
System voices are instant and cover many languages with word-by-word highlighting. The on-device AI voice downloads once, sounds consistent across devices, and lets you export the speech as an audio file.
Can I download the audio?
Yes. The AI voice saves as a WAV for free. Pro adds MP3 export and a whole-document mode that reads and exports a long piece in one go.
Can it read PDF or text files aloud?
Yes — Pro file import opens .txt and .pdf files and loads their text into the reader so you can listen to documents.
Can I change how a name or acronym is pronounced?
Yes. The Pro pronunciation dictionary lets you set “read as” replacements applied automatically right before speaking, without changing your original text.
Which browsers work best?
Recent Chrome, Edge and Safari expose the most system voices; the list depends on your operating system. Highlighting follows the word boundaries your browser reports, with a timing-based fallback where those aren't available.
Note: The number and quality of system voices depend on your browser and operating system. The optional AI neural voice loads a model from a CDN on first use and is then cached for offline use; all speech is generated in this browser and nothing you read is uploaded.
