when Circleboom is actually the better choice
Circleboom's audience-quality tools — bulk-unfollowing inactive or fake accounts, surfacing non-followers, and auditing who you follow — are genuinely more purpose-built than anything PostAI offers, since we don't do follower auditing at all. If your immediate problem is cleaning up a bloated or bot-heavy X following list rather than growing new reach, Circleboom's Pro or Plus tier is the better fit for that specific job.
