Frequently Asked Questions

Is Half Bold really free?

Yes! Half Bold is 100% free with all features included. No hidden costs, no premium version, no subscriptions.

How do I use it with Google Play Books?

Open Google Play Books in Chrome, upload your EPUB file, open the book, then enable Half Bold from the side panel.

Does it work with Google Docs?

Yes! Two methods: 1) Use the built-in Converter to open downloaded .docx files, or 2) Go to File → Share → Publish to web, then enable Half Bold on the published page.

What is the difference between Modern and Classic mode?

Modern Mode is the new standard: it paints highlights over the text without touching the website code, ensuring 100% stability on complex sites like Gmail. Classic Mode physically wraps words in bold tags, useful for older static websites.

Can I use it on PDFs?

PDFs need conversion first. Use our built-in Converter for DOCX/EPUB. For PDFs, check our eBook Reader page for recommended tools to convert PDF to EPUB/DOCX.

How can I improve my reading speed?

Half Bold is the best tool to improve reading speed. By bolding the first part of words (fixation points), it guides your eyes smoothly, reducing regression and sub-vocalization.

Is this good for ADHD Reading?

Yes! Many users consider it one of the best apps for ADHD. The visual anchoring points help maintain focus and prevent the 'drift' often experienced when reading with ADHD.

Can I customize the formatting?

Yes! Adjust intensity (1-5), customize Ink & Fade colors, and chose from 5 styles. Use the Advanced Preset Manager to save configurations for different reading environments.

Is my data private?

Absolutely. Half Bold works entirely locally in your browser. We don't collect any reading data or personal information.

Can I change the keyboard shortcut?

Yes! Open chrome://extensions/shortcuts in your browser URL bar. Look for 'Half Bold' and click the pencil icon to set your own custom hotkey (Default is Alt+B).

What browsers are supported?

Chrome, Edge, Brave, Opera, and any Chromium-based browser. Safari version is coming soon!
