Frequently Asked Questions (FAQ)

What does Caption Analyzer check?

It checks your caption's total characters, word counts, line break density (for mobile scanability), hashtag counts, emoji counts, and specific emotional cue keywords (such as curiosity, urgency, and proof words).

Can I use it for Instagram, YouTube, TikTok, or community posts?

Yes. You can toggle between different platform presets (Instagram, TikTok, YouTube Shorts, Bluesky, LinkedIn) to adjust target lengths and hashtag bounds.

Does it write the caption for me?

No. This tool is an analyzer, not an AI generator. It reviews your text copy and flags potential readability and formatting issues so you can refine it manually.

Is my caption uploaded to a server?

No. The analysis is performed fully locally inside your web browser. Your text drafts are not stored or transmitted.
