Editor-first study vault
Notes, flashcards, and review in a filesystem you actually want to use.
Kernel is a minimal study workspace inspired by GitHub's clarity: vaults for structure, markdown for control, embedded cards for recall, and a review loop that stays out of your way.
- Markdown-first notes with inline flashcards
- Vaults, folders, and documents in one tree
- Review queue powered by spaced repetition
Markdown sample
A note surface that keeps cards embedded beside the content.
# Glycolysis ```flashcard id: card-pfk front: What enzyme commits glucose to glycolysis? back: Phosphofructokinase-1 tags: metabolism, core ``` Use rich text when you need it. Keep markdown when you want exact control.
Vault workspace
Create study vaults, organize nested notes, and keep everything in a simple filesystem layout.
Embedded flashcards
Write cards directly in your notes, keep markdown as the source of truth, and sync review data automatically.
Focused review
Pull due cards into a clean queue so study stays lightweight and easy to return to every day.
How it works
The workflow stays simple from capture to review.
1
Create a vault
Start a workspace for a class, exam, or topic and keep related notes grouped together.
2
Write notes naturally
Use rich editing when you want it, or stay in markdown when you want tighter control.
3
Review what matters
Embedded cards flow into the scheduler, so the next session always starts with the right material.
Built for focus
A restrained layout that keeps the important actions visible.
Clear hierarchy, strong contrast, and minimal motion make the interface easy to scan on desktop and mobile.
The same visual language carries into the workspace and review screens so the app feels like one system, not a collection of pages.
