Features for Modern Research
A suite of professional tools designed to help you capture, organize, and export your digital discoveries.
Web Annotation
Highlight text, leave comments, and sketch directly on any live webpage. Your notes stay pinned exactly where you left them, even when you refresh the page.

Precision Drawing
Use our vector-based ink engine to circle, point, and sketch ideas with zero latency across any browser window. Perfect for design critiques and technical diagrams.
PDF Export
Archive your research forever. Export full-page annotations into high-quality, searchable PDFs with embedded links and metadata.

Cloud Sync
Your thoughts shouldn't be trapped on one machine. MarklyKit syncs every highlight and sketch across all your devices in real-time.
API & Integrations
Connect your research to Notion, Obsidian, or your own custom CMS via our robust REST API. Data portability is our priority.
