Caption & Hashtag Checker
Paste your caption and hashtags to catch cut-off risk, weak hooks and spammy tag mixes before you post.
What this checks
- Caption length against Instagram's visible-before-"more" cutoff (~125 characters)
- Hook strength — does your first line grab attention?
- Hashtag count against the recommended 3-8 range
- Duplicate or banned-pattern hashtags
Example
A caption starting with "Just wanted to share..." scores a weak hook warning — swapping the opener to a question or bold statement ("Nobody tells you this about home workouts...") passes the check and is far more likely to stop the scroll.
Why caption structure matters
Instagram truncates captions after roughly 125 characters with a "more" link — if your hook and CTA are buried past that point, most viewers never see them. The first line has to do the work of stopping the scroll on its own, before anyone taps to expand.
How to use this tool

Use cases

- Agency and freelancer workflows: run every client caption through the same checklist for consistency.
- New creators: learn the caption and hashtag rules by seeing exactly what gets flagged and why.
- Repurposing content: check a caption written for one platform before reusing it on another.
Frequently asked questions
How many hashtags should I actually use?
Instagram's own guidance is 3-5 relevant tags. This tool flags anything under 3 (too few for discovery) or over 30 (spam risk), with a sweet-spot recommendation of 5-15 for most accounts still building reach.
What counts as a "weak hook"?
Openers like "Just wanted to..." or "So..." that delay getting to the point. A strong hook leads with the payoff, a question, or a bold claim in the first 5-8 words.
Does this tool post or save my caption anywhere?
