Question 4

Which checks work on which files?

Accepted Answer

A Fact check takes a video, an audio recording or an image. The other reports look at video. You can ask questions about any file, documents and spreadsheets included.

Question 5

Does it read the post, or only the video?

Accepted Answer

The post too, when the site shows it: who posted it, when, what it said, its views, likes, comments and shares, the sound and the place.

Question 6

Does it work in other languages?

Accepted Answer

Yes. It transcribes and checks recordings in many languages and shows a translation beside the original transcript. The app itself is available in English, French, German, Romanian and Russian.

Question 7

What if my source is not on the list?

Accepted Answer

Upload the file itself. Any video, recording, photo or document in the formats above works, wherever it came from.

Who can see what I upload?
