Stay invisible to others.
Lexa restyles the page in place. Same site, same URL, same layout. If someone glances at your screen, they can't tell a reading tool is running. There's a keyboard shortcut to turn it on too, so you don't even have to open a popup. No separate reader tab, no banner across the top, nothing that says "this person needs help reading".
No account. Just download and go.
No signup, no email, no profile. You install it from the chrome store, you press the shortcut, and the page changes. Nothing about you leaves your browser. It's a tool for reading, not another app to log into.
Good defaults. Tunable.
Font, weight, line height, letter spacing, word spacing, column width, themes. Every slider is yours to move until the page reads the way you want it to. Change anything and it stays that way the next time you open a page.
Know when not to act.
On code editors, video sites, social feeds, search results, and maps, restyling the page just breaks it. So Lexa stays off there. The popup doesn't even show a toggle on those sites. There's no "enable anyway" button to fight with. And if there's a site that isn't on that list but you'd still rather Lexa skipped, you can add it yourself.
