Marginalia Labs builds local-first tools for writers and researchers. Your words live on your machine, not our servers. No subscriptions, no cloud lock-in — just thoughtful software that stays out of your way.
Whether you're writing a novel or annotating research papers, we believe your tools should respect your work, your data, and your focus.
Professional writing software for authors who care about craft. Write, analyse readability, compare your style to the masters, and publish — all from one app.
PDF research and annotation built for tablets. Highlight with your pen, organise notes by category, and build your research library — designed for the Surface.
We make opinionated software for people who take their work seriously.
Your files live on your machine. No cloud dependency, no accounts required to get started. Your data is yours — full stop.
One-time purchase. No subscriptions, no recurring fees. We think charging writers every month to access their own work is wrong.
Every feature earns its place. We'd rather do six things brilliantly than sixty things adequately. No bloat, no feature creep.
Built for Windows tablets from the ground up. Real pen pressure, real touch gestures — not a desktop app with touch bolted on.
Markdown, PDF, EPUB, DOCX. We use standard formats so you're never locked in. Take your work anywhere, any time.
Built with WinUI 3 for proper Windows integration. Fast startup, native feel, respects your system theme. No Electron here.
No credit card required. No account needed.
Just download and start working.
Available on the Microsoft Store for Windows 10 & 11
