Hi Product Hunt! 👋 I’m thrilled to introduce WriteFlow. What inspired me & the problem I was trying to solve: As a student and a developer, I spend hours staring at screens reading heavy documentation, PDFs, and long-form text. I found myself constantly losing focus, rereading the same lines, or dealing with eye strain. I wanted a tool that forced me into a state of deep work, but existing solutions were either bloated with features I didn't need, required expensive monthly subscriptions, or processed my private documents on their servers. I built WriteFlow to solve my own focus problem. What it is: WriteFlow is a distraction-free reading and text-to-speech (TTS) engine. It uses kinetic text highlighting and a custom typography system to guide your eyes and anchor your attention, making it incredibly easy to consume long documents without losing your place. How the approach evolved: What started as a simple local coding experiment evolved into a strict "privacy-first" challenge. I decided to build the entire engine using pure, vanilla HTML/CSS/JS. No heavy frameworks and no backend servers reading your data. Local-First: Your documents and text never leave your browser. Bring Your Own Keys (BYOK): If you want premium AI voices via the "Perfect Sync" TTS feature, your API keys are stored strictly in your local storage. Offline Ready: It is structured as a PWA, so you can install it and use it entirely offline. I would love to hear your feedback on the kinetic highlighting feel, the typography, and the overall UI. Drop your thoughts, bug reports, or feature requests for v1.1 in the comments below! Thank you so much for checking it out! 🚀
