Everything in one place
Every block you need: code with syntax highlighting, math (KaTeX), Mermaid diagrams, callouts, and wiki-links. AI assist on any selection. Version history with diffs.
Generate flashcards from any page in one click. Review with a scientifically-proven SM-2 engine. Track streaks, heatmaps, and card-level progress.
Build prompt templates with {{variables}}. Run on any page or selection. Bring your own OpenAI, Anthropic, or Gemini API keys. Sync your library to GitHub.
Infinite canvas for sketching, diagramming, and visual thinking — embedded directly in your notebook. Shared, versioned, and searchable alongside your notes.
Dictate notes hands-free. Your transcript lands in the editor as structured text, not a wall of audio. Works in every browser with optional Deepgram for accuracy.
Chat with your notes, ask questions about a page, or run multi-step AI prompts. Every AI action auto-snapshots a version so you can always roll back.
The full knowledge loop
Write, dictate, or import. Every idea lands in one searchable, wiki-linked workspace — no copy-paste between apps.
One click turns any page into flashcards. Spaced repetition schedules your reviews so nothing slips through.
Reusable AI prompts with variables. Run on your notes, get AI to rewrite, summarize, or synthesize — then sync your library to GitHub.
