50 books read, zero frameworks forgotten
You've read dozens of non-fiction books. You've highlighted key passages, frameworks, and ideas. But three months later, all you remember is "that book was good." Highlyt turns your reading into a searchable, connected knowledge base that compounds over time.
Start Free TrialHow book readers use Highlyt
Color-code mental models and frameworks
Yellow for frameworks, blue for questions you want to explore, green for evidence. After 50 books, search 'all frameworks about decision-making' and see every mental model you've collected.
Connect ideas across books
The compounding concept from Atomic Habits links to the second-order thinking in The Most Important Thing. Draw that line. Your knowledge graph shows how your reading connects over years.
Ask AI about your reading history
Connect ChatGPT via MCP. Ask: "What have I learned about leadership across all my books?" It searches your color-coded highlights and linked frameworks, not the internet.
Keep your reader, use Highlyt for synthesis
If BookFusion, Kindle, Apple Books, or Readwise already handles reading and capture, keep it. Bring highlights to Highlyt when you need search, meaning, graph links, and AI context.
Frequently asked questions
What is the best app for organizing book highlights?+
It depends on the job. Readwise is stronger for mature imports and spaced repetition. BookFusion is stronger for ebook library management. Highlyt is built for readers who want semantic color-coding, a knowledge graph linking ideas across books, and graph-aware AI context.
Can I use Highlyt with eBooks (EPUB)?+
Yes. Upload any DRM-free EPUB file and highlight it with the same semantic colors you use for PDFs. EPUB highlights appear in the same search results and can link into your knowledge graph alongside PDF highlights.
Does Highlyt import existing Apple Books highlights?+
Not today. Highlyt supports direct PDF and DRM-free EPUB reading, plus supported Kindle import paths. If your main pain is Apple Books history sync, do not treat Highlyt as a replacement yet. Use it for future reading or for files you upload directly.
How is this different from Kindle highlights?+
Native Kindle highlights are hard to search across books, color-code by meaning, link into a graph, or export as structured AI context. Highlyt focuses on those post-capture workflows after supported Kindle imports land in your library.
