My workpalce uses Glean and since it was connected to Slack it has become significantly worse. It routinely gives incorrect or VERY incomplete information, misattributes work to developers who may have casually mentioned a project at some time and worst of all presents jokes or sarcastic responses as fact.

Not only is it an extremely poor source of information, it has ruined the company's Slack culture as people are no longer willing to (for lack of a better term) shitpost knowing that their goofy sarcasm will now be presented to Glean users as fact.
