Subtitle File Translator for Malay, English and Chinese
Upload an .srt or .vtt file and get a translated subtitle file with timings kept intact, plus a side-by-side editor to fix lines before export.
Economics
- Pricing example
- $9 for 120 subtitle minutes (first 10 minutes free)
- Daily math
- 2-3 packs a day x $9 = $18-27/day.
- Target if you hit the daily math
- Target: $550 - $800 / month if the daily math is hit
Audience and urgency
Audience: YouTubers, course creators, corporate trainers and video agencies in Malaysia and Southeast Asia publishing for audiences that read different languages.
Urgency: Auto-generated captions usually come in one language, and translating subtitle files by hand easily breaks the timing codes. Creators want a second-language version without re-timing every line.

One-shot master prompt
Build a "Subtitle Translator" web app in React with Tailwind CSS and a serverless LLM endpoint. Core requirements: 1. Upload .srt or .vtt; parse into cues (index, start, end, text) in the browser. Show total duration and credits needed (1 credit = 1 subtitle minute). 2. Translate in batches of 30 cues, sending 3 cues of context before and after; the model must return exactly one translation per cue ID (validate with a JSON schema and retry mismatches). Languages: English, Malay, Simplified Chinese, Indonesian. 3. Glossary: user-defined terms that are kept as-is or mapped to a fixed translation; applied in the prompt and checked after. 4. Side-by-side editor with original and translated text, warnings for lines over 42 characters or more than 17 characters per second, and inline editing. 5. Export SRT and VTT with original timestamps. 10 free minutes, then Stripe Checkout ($9 for 120 minutes). Files are not stored after export.
