YN Translation Workshop is a local Electron CAT workbench for literary and game text. A real Pi Agent harness, not a prompt pack: optional AI first-pass translation and proofreading, then human-first line-aligned review with staging and completion gates. Glossary, character bible, style guide, and translation memory stay on your machine. Connect ChatGPT, Claude, Grok OAuth, or any OpenAI-compatible API. Windows installer + portable exe, EPUB/TXT, LAN remote with PIN. MIT. v2.0.7.
