ZetaMarker is a Canada-based company focused on enhancing online research. Our intuitive workspace helps you manage reading, annotate important information, and highlight key insights across the web and PDFs.
What we build
- A browser extension for highlighting and note-taking on web pages and PDFs
- A web dashboard for organizing, searching, and syncing your library (Pro)
- Tools designed for privacy-first workflows — local storage by default, cloud sync when you choose it
Who it's for
Researchers, students, journalists, and anyone who reads seriously on the web and wants to keep what matters without losing context.
Our principles
- Minimal permissions — we ask only for what highlighting requires
- Your data, your control — local-first by default; cloud is optional
- Continuous improvement — we ship features based on real reading workflows
