OMCS-Original Mermaid Creation Support-

This is a Mermaid Editor-type application that can directly convert Mermaid into flowcharts and mind maps. Compared to existing editors, it allows you to freely customize the appearance and styling. As a trial, we've equipped it with Google's Built-in AI functionality, so you can output code in Mermaid format within the app. However, since this requires various setup procedures, if it's too much trouble, you can simply paste code that you've generated from ChatGPT, Gemini, or similar services directly into the app.

AAUI Designer Pro

AA (ASCII art) is convenient when conveying UI images to LLMs (AI). While you could try to convey images visually, that only works with multimodal-capable models. However, with AA, even LLMs with very low parameters can read and understand it. You can convey UI images without being limited by the model type. Plus, with AA, you can make edits in a text editor. No specialized tools are needed. However, creating AA is difficult. That's why I created a tool that makes it easy to generate AA by arranging parts in a PowerPoint-like interface. It supports .md, .txt, and .png output. It has layer separation functionality, real-time preview, and the ability to load and reference images while creating, so I believe it has sufficient performance for practical use.
