## Accurate captions, the right way

The Subtitles app turns any video into accurate, editable captions. You transcribe with AI, correct the text and fine-tune every timestamp in a player-synced editor, and export clean WebVTT, SRT, or plain text.
### The building blocks

- **Project** — one video to caption. Its video comes from a Digital Asset, a direct upload, or a URL.
- **Track** — one language's captions for a project. A project can have many.
- **Cue** — a single caption: an in/out time plus text. Cues are the source of truth; exports are generated from them.
- **Standard** — the QA rules (characters per line, reading speed, durations, gaps…) checked as you edit.
