Keep every idea
in one place.
Write, draw, present, and create video without scattering your work across separate apps. Your files stay local; managed encrypted sync is available as an experiment during beta.
macOS 14+ on Apple Silicon · v0.2.0
Drawing
An infinite canvas powered by WebGPU compute shaders. Pressure-sensitive brushes, stamps, glow effects, and lasso selection for fluid, direct canvas work.
Notes
Markdown files on your filesystem with a full rich text editor on top. Wikilinks, backlinks, graph view, slash commands, and code blocks with syntax highlighting.
Presentations
Create slides without leaving your vault. Drawing overlay with favorite pens, fullscreen presenter mode with speaker notes, and templates for quick creation.
Video Editor
Multi-track timeline with 20+ transitions, keyframe animation, color correction, audio mixer, speed ramping, and voice-over recording. All inside your vault.
AI that reads your vault
Your files are markdown and YAML -- the most AI-friendly format that exists. Rewrite, summarize, translate, and ask questions with context from your notes. Run models locally in your browser with WebLLM, or connect Anthropic, OpenAI, and Google.
Create anything from your workspace
Generate presentations, drawings, images, animations, voiceovers, and video without managing separate AI provider APIs. Use Creative Credits, or connect supported subscriptions like ChatGPT or Grok. Notidian will route each task to the best model for quality and cost.
Local by default
Canonical work is stored as files on your filesystem, including Markdown, scene data, and original assets. No cloud account is required for local use. The client is proprietary; its documented file formats and future protocol components are distinct from the application source.
Managed encrypted Sync is experimental. The current beta server cap is the configured quota (1 GiB when no override is set), not the future Pro allowance.
One place for your creative work.
A useful local core stays free.
Your drawing becomes a slide. Your notes reference your videos. Your calendar connects to your projects. Everything flows together because it was built to work as one. No jumping between tools. No scattered files. No friction.

AI can't do the push-ups for you.
It can't build your understanding of a book.
It can't develop your drawing hand.
It can't grow your ideas.
Skills grow when you use them. They fade when you don't.
Notidian gives you AI as a coach, not a replacement.
Write your own words. Draw your own ideas. Build your own mind.

Portable canonical files on your filesystem. The client remains proprietary
