Reading without eye movement
Words appear in one place, aligned on the point where the eye recognises them. The pace adapts to word length and punctuation, so sentences never run away from you.
Read it twice as fast.
Paste text or drop a PDF and read it one word at a time in a fixed spot, with no eye movement. Readio remembers every document and the exact word you stopped on.
PDF, TXT, MD, EPUB
Everything stays in your browser. No file is ever uploaded.
It remembers where you are
Every document keeps its position, progress and time left. Close the tab mid-sentence and you resume three words back, with context.
Read aloud
Your device's own voice reads the text while Readio highlights the exact word being spoken. Free, offline, no limits.
Common questions
- Where are my documents stored?
- In your browser. Readio has no server that could receive them. PDFs are parsed on your device and never uploaded.
- How fast can I read?
- An average adult reads around 240 words per minute. With this method 400 to 600 is normal. Start at 350 and raise it in steps of 25.
- Does it work on scanned PDFs?
- No. Readio reads a PDF's text layer. A scan is an image, and we do not do text recognition yet.
- What does it cost?
- Nothing. Readio is free and needs no account.
