The Future of Knowledge Workers

A great annotation tool should disappear into the page and let you capture ideas the moment they land. That's the bar we're setting.

The tools we use to read, think, and remember have barely changed in a decade. Most knowledge still lives in browser tabs that get closed before we can act on it.

By layering highlights, notes, and drawings directly on the web, MarklyKit turns every page into a workspace you can come back to — organized in folders, searchable by tag, and synced to your dashboard.

Watch how it works

The Workflow

01

Capture

Highlight text or draw on any page element. Your highlights stay exactly where you placed them, even when the page updates.

02

Synthesize

Add sticky notes and connect ideas across multiple pages. Turn scattered highlights into clear, structured insights.

03

Connect

Plug your research into Claude, ChatGPT, or Grok via MarklyKit's built-in MCP server. Let the AI search, summarize, and reason over what you've saved.

04

Archive

Export your annotated workspace as a searchable, citation-ready PDF for archiving, review, or sharing.

Core Capabilities

Everything for the expert.

Semantic Highlighting

Your highlights stay pinned to the exact text you selected — even when a website updates its layout or redesigns its pages.
