Frequently Asked Questions

Quick answers to common questions

What is bionic reading?+

It bolds the first portion of each word so your eyes can fixate faster while skimming. The rest of the word is filled in by your brain.

Is the preview safe for user HTML?+

Yes. Preview is rendered as React text nodes with <strong> — your input is never injected as raw HTML.

What do Light / Medium / Strong change?+

They control what fraction of each word is bolded (roughly 30%, 50%, and 65%).

Is my text uploaded?+

No. Conversion runs entirely in your browser. Your inputs are not sent to our servers.
