Transcript Keyword Index- Deterministic keyword index with timestamps
Build a deterministic keyword + phrase index from transcripts or subtitles. The tool maps exact-match tokens and phrases to timestamped occurrences with bounded context.
How it works
- 1
Provide Transcript Text, Subtitle Cues (optional), Artifact JSON (optional).
- 2
Run the tool to generate the output.
- 3
Copy or download the result for immediate use.

}Configuration
Transcript-only inputs emit null timestamps. Add subtitles for cue-based timing.
When provided, subtitle cues supply timestamp ranges per segment.
If provided, the tool re-emits the artifact without re-indexing.

Frequently Asked Questions
What does the index include?
Each token and phrase key includes all occurrences with timestamps (when available) and context snippets. The output is deterministic and offline-friendly.
Do I need subtitles?
No. If you only provide a transcript, all occurrences will carry null timestamps and a warning is emitted.
Does this perform semantic search?
No. The search is exact-match on normalized keys. Stemming and fuzzy matching are intentionally out of scope.
