Editor-first study vault

Notes, flashcards, and review in a filesystem you actually want to use.

Kernel is a minimal study workspace: vaults for structure, markdown for control and embedded flashcards for recall.
Everything all in one place, so you can focus on the work that matters.

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.

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.

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.

Create a vault

Start a workspace for a class, exam, or topic and keep related notes grouped together.

Write notes naturally

Use rich editing when you want it, or stay in markdown when you want tighter control.

Review what matters

Embedded cards flow into the scheduler, so the next session always starts with the right material.
