Pros
  • Fully open source under MIT, including code, prompts, docs, and original assets
  • Runs as a single standalone HTML file with offline PWA support and local-storage auto-save
  • Ships a rigorous structured format (NDM v10 / OMNY YAML) so storyboards are diffable and pipeline-friendly
  • Includes ready-made LLM prompts that convert prose manuscripts into typed manga-name YAML
  • Model-agnostic — works with any LLM the creator prefers (ChatGPT, Claude, Gemini, local)
  • Pattern-template library (layouts A–Q) speeds up common page compositions
  • No account, no cloud, no telemetry — usable behind studio firewalls
  • Eliminates the worst part of SRS: hand-authoring cards
  • Native MCP hooks into Claude and ChatGPT for inline capture
  • Modern FSRS scheduling, not legacy SM-2
  • Offline PWA with cross-device sync
  • Cheap Pro tier at $8/mo
Cons
  • Japanese-only UI and documentation; non-Japanese users will need to translate the interface
  • No built-in AI — you must copy prompts into an external LLM and paste OMNY back
  • Small solo project (single maintainer, ~10 GitHub stars) with limited support and roadmap visibility
  • Not a drawing tool — outputs storyboards and structured data, not finished art or pages
  • Local-storage-only persistence means clearing browser data can lose work if not exported
  • Anki sync is one-way only
  • Free tier capped at 30 AI notes per month
  • AI-generated cards still need human review for accuracy
  • Smaller ecosystem than Anki's plugin world
