Hi Product Hunt! 👋 Hi, Accordian here, the maker of Bionic Font Converter. The inspiration for this came directly from my own screen fatigue. Between grinding through dense CSE course materials and binging massive translated web novels late into the night, my eyes were constantly burning out. I loved the concept of artificial fixation points to guide my focus and increase my reading speed, but I kept running into a huge roadblock with the current market leaders. The official Bionic Reading app and tools like Jiffy Reader are great, but they require you to upload your personal PDFs and EPUBs to their remote servers. That felt like a massive privacy risk for personal documents, so I decided to build a purely local alternative. Here is what makes it stand out: 100% Client-Side: Everything—from parsing 1000-page EPUBs to formatting DOCX files—happens locally right inside your browser. Your data never leaves your device. Total Control: Real-time adjustment sliders let you tweak the Fixation Strength and Boldness Weight to match your exact visual preference. Zero Friction: It's completely free, with zero ads and no sign-ups required. I built this to be the fastest, most private reading tool out there. I would absolutely love to hear your feedback on the UI and how the conversion feels for you! Let me know if you have any questions!
