About
Highlyt is a PDF and document annotation tool that lets readers assign semantic meaning to highlights using color codes, link related ideas across multiple documents into a knowledge graph, and connect that structured context directly to AI assistants like Claude and ChatGPT via MCP. It targets serious readers who want their captured highlights to be immediately useful rather than buried in folders. The product bridges the gap between passive capture tools like Readwise and AI-ready, structured thinking context.
Problem
Readers accumulate valuable highlights across many documents but have no structured way to make that context usable for AI tools or quick retrieval.
For
Researchers, students, and avid readers who use AI assistants for synthesis and analysis
How it works
Users upload PDFs or EPUBs, annotate highlights with semantic color meanings, link ideas across documents into a knowledge graph, and expose that structured data to Claude or ChatGPT via an MCP server.
