Highlyt
You highlight. You forget. Highlyt connects the dots.
Color-code ideas by meaning. Link highlights across books and papers. Every reader knows the pain: thousands of highlights across PDFs and books, all orphaned, never connected. Highlyt makes every highlight a node and every connection a typed edge (supports, contradicts, expands, questions). The result: a knowledge graph of your actual thinking.
Hey Product Hunt 👋
I'm Mayank, the builder behind Highlyt.
The frustrating moment that started this: I had 200-300 highlights spread across Readwise, Kindle, and PDFs, completely useless. Every tool I tried had solved capture beautifully. None had solved connection.
When I tried to write or think deeply on a topic, I couldn't see how my reading from one book touched what I'd highlighted in a paper three months ago. The insight existed. I just couldn't find it.
Highlyt's core thesis: capture without judgment is just noise. When you highlight something, you have a split second of clarity, you know what kind of idea this is. That judgment is what Highlyt forces you to record.
What makes it different:
— Semantic highlight types: core idea, disagreement, open question, action item
— Typed cross-document links: supports, contradicts, expands, questions
— AI auto-suggests connections between your highlights, you confirm or reject. Graph density grows without removing your judgment from the loop.
— MCP server that plug your reading graph directly into Claude or ChatGPT
Live on web, and Chrome extension.
If you're a researcher, a heavy reader, or someone building with AI, I'd genuinely love to know where your current reading workflow breaks down. What's the moment the tool fails you?
