Bionic reading bolds the first part of every word, on the theory that your eye completes the rest without reading each letter. This free bionic reading converter applies it to any text, with the emphasis and size adjustable so you can find what suits you.\n\nBeing straight about the evidence: it is thin. The studies are small, their results mixed, and the stronger speed-reading claims are not well supported. What a lot of readers do report — and what seems to be the genuine benefit — is that it makes holding your place on a line easier, particularly in long unfamiliar text. That is a modest claim, and a defensible one.\n\nThe emphasis slider controls how much of each word is bolded, defaulting to about half. Short words always get at least one bold character so the rhythm stays consistent. Punctuation is deliberately excluded, so a leading quotation mark or a trailing full stop never ends up bold — a small detail that keeps the result readable rather than visually noisy.\n\nCopy with formatting places rich text on your clipboard, so the bold survives a paste into Word, Google Docs or an email, and you can export a standalone HTML file for reading later. Everything runs in your browser. Pair it with the Readability Checker to see how difficult the text is to begin with, or the Reading Time Calculator to gauge how long it will take.

Does it work? Honestly, the evidence is thin. The studies are small and their results mixed, and there is no good support for the stronger speed-reading claims. What plenty of readers do report is that it makes it easier to hold their place on a line, which is a reasonable enough reason to use it — just not a scientifically established one.
Bold is applied to the letters only, so leading quotes and trailing punctuation stay unemphasised. Copying with formatting preserves the bold in Word, Docs, and email.
