Open the companion tool →Why context checking comes before clone detection
A genuine sentence can be misleading when its question, preceding qualifier, date, or translation is removed.
The earliest upload, full program, transcript, and independent reporting can resolve many claims without pretending visual inspection proves authenticity.
The protocol
- Save the clip URL, uploader, caption, and viewing date.
- Search for the full interview from the broadcaster, speaker, or event organizer.
- Compare the preceding question and following answer.
- Check subtitles against an official transcript or a qualified translation.
- Describe unresolved uncertainty when sharing, or do not share the clip.
