On WhatsApp, hashtags behave very differently from Instagram or Twitter: they are inert in chats and only useful on Channels, where a small, focused set helps subscribers find your topic. This helper counts the hashtags in your update, flags malformed or duplicate tags, and totals their character cost so your post stays clean and credible rather than spammy.
How it works
The tool scans your text with a pattern that matches each token starting with a hash symbol and running until the next space or hash. For every tag it checks the body against the rule “letters, numbers, and underscores only” — anything with a space, punctuation, or symbol is malformed, and an all-number tag does not group content. It also remembers tags it has already seen to flag duplicates, and it sums the character length of every tag so you can see how much of your caption budget they use. The status line maps your count to a 1 to 3 recommended range.
Tips and example
Treat hashtags as a Channel-only tool. Pick one broad topic tag and one or two
specific ones — for a local news Channel that might be #news, #yerevan, and
#update. Avoid punctuation inside tags: #back-to-school breaks at the hyphen,
so write #backtoschool instead. If the helper flags duplicates or shows red on
the count, trim back to three clean tags and spend the saved characters on a
clearer caption.
