I built A4 Editor because I couldn't find a truly distraction-free writing tool that also respected my privacy. As an interior designer, I needed a clean digital page for notes — no toolbars, no cloud lock-in. I added BYOK AI so everyone can use their own API key. My wife uses it for her books. It's free, offline-first, and your data stays yours. Would love your feedback!
