@Gargron I meant the app, you don't need an account to start browsing on the app or web.
Regarding video editing, they have a separate app called CapCut. IG has pretty advanced video editing too, but their Reels feature is full of TikToks, so IMO its more than just that.
@dansup Sure, I agree that's beneficial. Though I doubt they would allow browsing anonymously if they didn't have a good algorithm for showing popular content.
