Principle
PSI can analyze one YouTube video or follow an author. The technical precheck always happens before payment: valid URL, likely usable transcript, requested mode, and volume estimate.
Author modes
- standard: videos since January 1 of the current year, then future videos.
- past: available past videos until today, with no future tracking.
- all: all available past videos, then future videos.
- all/YYYY: videos since January 1 of the selected year, then future videos.
Stored data
PSI stores no client data. For a request, the system keeps only the video or author URL, requested mode, amount, and a hash of the accepted payment reference.
Limits
A video without a transcript is not published at first. Reliable external sources may be absent: in that case, the tuit may show zero external references rather than cite a weak or invented source.
Status
The public request page will be connected progressively to the API. Until then, precheck remains manual or reserved for internal tests.
