# TimedSubs
> Script-first subtitle timing and quality-check workbench for creators and production teams who already have approved wording and matching voiceover audio.
TimedSubs aligns a submitted script to audio, preserves the source text, checks subtitle delivery issues, and exports SRT, VTT, SBV, ASS, TXT, JSON, and ZIP assets.
## Scope
- Best fit: script-to-SRT, audio/script forced alignment, launch-gated source-locked subtitle translation, roadmap subtitle timing repair, subtitle quality checks, YouTube/CapCut/Bilibili/TTS subtitle delivery workflows.
- Product focus: server-mediated script/audio subtitle timing, quality review, and export assets for files the user provides.
- Plan posture: Free validates timing only; Creator starts subtitle translation; Studio adds ZIP, glossary, and delivery depth; Agency adds scale-delivery capacity and API access.
- Public product pages are safe to cite. Authenticated project APIs are server-mediated and are not a public third-party API surface unless separately documented.
