When "FSRS" is first used it's a clickable link, and the first sentence on that link is:

> FSRS (Free Spaced Repetition Scheduler) is a modern spaced repetition algorithm that was developed by Jarrett Ye.

If I do a search of "flexible spaced repetition software" I get no results, which strongly suggests the dumb guesser you're using guessed something plausible to placate its user. This is common behaviour for this type of software.

In summary, I politely suggest you critically review how you interact with knowledge on the internet.
