All three of Marcus's points are right, and the tool is built assuming you'll do them.
Worth being explicit about the philosophy: automation should remove the *labor* of posting, not the *judgment* behind it. The system handles cadence, distribution, dedupe, and rendering. What to say and who you're saying it to stays yours. The accounts that look robotic are usually the ones that handed over judgment too, not just labor.
Concretely, the features that support Marcus's list: multiple caption variants per pool, the 48-hour per-account guard so nothing repeats too close, category templates for varying content type, and hashtag rotation. Use them and the "on rails" feel mostly goes away.
