Fragment

An AI-native notebook that treats your thoughts as structure

Visit Website
November 19, 2025 Hi everyone — I just launched the product page for Fragment.

I’m building Fragment because modern tools still treat thinking as flat text.

But real thinking has structure: assumptions, context, flows, goals, and boundaries.

Fragment is an AI-native notebook that lets you write:

  • normal Markdown for your main thoughts

  • YAML for assumptions, intentions, and “thinking settings”

  • small Scene/Flow diagrams for relationships and processes

All in one place — readable by both humans and AI.

I’m building this solo (design, backend, frontend, protocol design, everything).

If you’re curious about structured thinking, AI-compatible notes, or DSL-based tools,

I’d love your feedback.

👉 Happy to answer any questions!

Thanks for having me here — excited to share more as the product grows.

Modern tools treat thinking as flat text. Real thinking has structure — context, assumptions, flows. Fragment is my attempt to build an AI-native notebook that preserves that structure.
