Free tools / Caption generator
Turn one idea into 3 ready-to-post captions — hook first (the feed only shows the first line), one clear CTA, hashtags sized to the platform.
Caption rules the algorithm cares about: Instagram cuts the feed preview at ~125 characters, LinkedIn at ~210, TikTok at ~80 — so the first line has to carry the hook alone. This tool writes for the cut-off first, then the platform's hashtag sweet spot (3–5 on Instagram and TikTok, 1–2 on X, usually none on Facebook).
