renga: Claude Code Multiplexer

Get notified with sound + voice reading when Claude Code or Codex finishes. You can tell which one finished just by listening. With VOICEVOX integration, you can even have Zundamon speak.

A custom terminal emulator for Windows (made with Rust + egui). Arrange multiple shells such as PowerShell and Command Prompt in vertical tabs, with color-coding available for each tab. Save frequently-used tab configurations as "presets" and call them up at startup or when creating new tabs. Supports Japanese input and display, opening via right-click from Explorer, and scrollback functionality.

I created a macOS app that lets you select and bring up open windows from a thumbnail list.

Share text and hand-drawn pictures in real time! It's a real-time online whiteboard. With no time lag, you can share what you want to convey visually while having conversations with people in remote locations. No troublesome member registration required. You can use it by simply deciding on any whiteboard ID and sharing that ID and URL. Try opening two windows to see if it's reflected!

A whiteboard that can be shared with family (friends??). Easy to use even for children who don't understand the concept of messages, and I want it to be used like a bulletin board where they can leave notes for their parents when they want to tell them something!

It's a game of Agents skills that you can play during breaks from AI coding. If you type $mine in Claude code or similar, a dwarf will go out mining for you on the CLI.

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.
