- Bionic emphasis across page content

Read Flow is private by design. Page content, PDF content, reading activity, and settings are processed locally in your browser and are not transmitted to ScholarSail or third parties. The extension contains no analytics, advertising, tracking, or account requirement.
Some protected browser pages and scanned PDFs without extractable text cannot be reformatted.
