Start with the expected course

Try the complete ten-lesson example, or select your UTF-8 SRT/VTT captions. Expected paths come from your explicit manifest.

Caption filesCaption folder

Folder selection removes only the selected root folder. Individual selections use basenames; identical basenames are ambiguous. Maximum 200 files, 2 MiB each, 20 MiB total.

Expected manifest, glossary & policy

Changing these JSON inputs clears earlier decisions. Every lesson needs a unique ID/path and an explicit required boolean. Glossary matches are literal hints.

Know the limits

Plain-text SRT and a documented WebVTT subset. STYLE, REGION, cue settings and markup are flagged for external review. Valid WebVTT can overlap; the overlap check is your selected policy.

Glossary matches can be wrong in context. Missing terms are not errors. Review the source video yourself.

Read README.md and LIMITATIONS.md in your download. The app can run without a server; optional localhost instructions are included.

REVIEW WORKSPACE

Ready when you are

Select files and run review. Nothing is uploaded.

Keep the review record

Exports retain unresolved findings. File/settings hashes identify what was reviewed; they do not prove correctness. No source caption files are rewritten.
