TikTok Caption & Hashtag Formatter

TikTok currently allows up to 4,000 characters in a caption, but only about the first 150 characters are visible before the “…more” truncation on the For You page. This means the first 150 characters are the ones that matter most for engagement. This tool tracks that 150-character visible budget so you can optimise what viewers actually see without tapping “more.”

Yes. On TikTok, hashtags are part of the caption text itself — there is no separate hashtag field like on some other platforms. Every character in your hashtags, including the # symbol, counts against your visible character budget. This tool tracks caption and hashtag characters together so you can see exactly how much visible space you have left.

TikTok’s own creator guidance suggests 3–5 targeted hashtags per post. Fewer than 3 limits discoverability, while more than 5–10 can dilute your reach and eat into your visible caption space. The key is relevance: each hashtag should describe your specific content rather than being a generic popularity tag. This tool gives you a real-time count and status indicator so you can stay in the optimal range.

Generic FYP hashtags like #fyp, #foryou, and #foryoupage were widely used in TikTok’s early days, but TikTok’s own creators liaison has confirmed that these tags do not help your video reach the For You page. The algorithm surfaces content based on watch time, engagement, and relevance — not because a specific hashtag is present. Using FYP tags wastes valuable character space that could be used for targeted, niche hashtags that actually help the algorithm categorise your content.

A TikTok caption hook is the text visible in the first line before the viewer taps “more.” It needs to work in roughly 60 characters because that’s where TikTok truncates the first visible line in the feed overlay. The best hooks create curiosity (“The one thing nobody tells you about…”), use specific numbers (“This $3 hack saved me $200”), or directly address the viewer (“You’re doing this wrong”). This tool scores your first line across five factors and gives you specific tips to improve it.
