    Frequently noticed differences

    "My TikTok reply got cut off." TikTok caps replies at 150 characters including emoji. ReplyZen's reply editor shows a live counter so you can rewrite before publishing.

    "I tried to @mention someone in a TikTok reply and it disappeared." TikTok doesn't let third-party apps add mentions to replies, so they're stripped. Facebook and Instagram both support mentions.

    "Why can't I like an Instagram comment?" Instagram doesn't offer a way for third-party tools to like comments. Facebook and TikTok do.

    "How accurate is TikTok's Ads vs Organic split?" ReplyZen separates TikTok ads and organic posts when it can, but TikTok doesn't expose a single reliable ad flag. The split is best effort, so some posts may remain unclassified or land in the wrong bucket.

    "When will TikTok comments arrive in my inbox?" Usually within a few minutes — noticeably slower than Facebook and Instagram, which deliver them instantly. This is TikTok's platform behavior and the same everywhere.
