Check an Instagram caption (free)

How Instagram's feed shows a caption (the first ~125 characters before "… more") and what to fix before posting: at most 5 hashtags (Instagram's limit since 18.12.2025 — POST /v1/social/publish keeps the first 5), the first line, an opening greeting or emoji, links (not clickable in a caption), more than one ask, emoji density, tags that describe nothing and, with keywords, the search terms missing from the text. Hebrew and English. Free; nothing is sent anywhere.
