SubFly AI

About this project

SubFly AI is a localization SaaS designed to solve the critical flaws in current AI translation wrappers: context loss and formatting destruction. Built specifically for Anime, Donghua, and OTT localization, it leverages advanced chunking, translation memory, and a "Bring Your Own Key" (BYOK) architecture to deliver fast, highly accurate .srt, .vtt, and .ass translations.

The system features an automated parsing engine that converts subtitles into strictly enforced JSON payloads, processes them in rolling contextual chunks, injects custom glossary terms, and re-compiles the exact file format seamlessly via asynchronous Celery/Redis tasks.

Highlights

  • Advanced parsing for .srt, .vtt, and .ass preserving exact formatting
  • Rolling contextual translation memory via 50-line chunks
  • "Bring Your Own Key" (BYOK) architecture for LLM providers (Gemini)
  • Custom Glossary Engine with targeted term injection
  • High-performance asynchronous background processing using Celery
  • Modern responsive dashboard built with Next.js, Tailwind, and TanStack Query
