What is it?

AiNiee is a translation tool focused on AI-driven translation of long and structured text. It handles RPG and SLG game text exported by extraction tools such as Mtool, Translator++, ParaTranz and RenPy, as well as EPUB and TXT novels, SRT, ASS, VTT and LRC subtitles, and Word, PDF, Markdown and PowerPoint documents.

Users drop a folder of source files into the interface, and the tool detects file types and languages automatically before translating. It is designed for long texts, using techniques such as a lightweight translation format, chain-of-thought prompting, an AI glossary and context linking to keep terminology and tone consistent across a whole work. Prompts can be adjusted with base instructions, character introductions, background settings and translation style, and there are one-click polishing and term extraction functions.

AiNiee works with online LLM APIs and with local models run through tools such as LM Studio, Ollama and Sakura Launcher. It supports multi-key rotation, where several API keys are separated by commas to spread load and speed up translation.
