Paste a caption and see how many hashtags it carries, which ones repeat or won't link, and whether it clears each network's rules — including Instagram's five-hashtag cap introduced in December 2025. Free, instant, and runs entirely in your browser.
Paste the whole caption, hashtags included. The counter separates unique tags from repeats, flags tags that won't become links, and checks the total against each platform's published limit.
Within the cap — hard limit on posts and Reels since December 2025
Instagram capped posts and Reels at five hashtags in December 2025, down from thirty. Its own framing: tags help search, not reach — a few precise ones beat a long generic list.
Threads
Within the cap — one topic tag per post
Threads uses topic tags rather than hashtags, and allows exactly one per post.
YouTube
Within the cap — above 60, every hashtag on the video is ignored
Up to three hashtags show above the title; past 60 in the description YouTube ignores all of them.
TikTok
2,200 characters left
No published hashtag cap — they share the 2,200-character caption budget with your copy.
X / Twitter
280 characters left
No published cap, but every hashtag spends part of the 280-character post.
3,000 characters left
No published cap. LinkedIn's own guidance favours a small, specific set over a long list.
Bluesky
300 characters left
No published cap; hashtags count against the 300-character post like any other text.
A thirty-hashtag block that was standard on Instagram until December 2025 now breaks its five-tag cap, is twenty-nine tags past what Threads accepts, and can spend more characters than a Bluesky post has in total. Oxhype writes a per-platform tag set sized to each network from a single upload, so one caption doesn't have to satisfy seven sets of rules.
Drop in the full caption with its tags. Nothing is uploaded — the parsing runs entirely in your browser.
Unique tags, repeats, digits-only tags that won't link, stray hash symbols, and the characters the block spends.
Instagram's five, Threads' one topic tag, YouTube's sixty-hashtag cutoff — plus the character budgets that act as the real limit elsewhere.
This counter tells you where a caption breaks a rule. Oxhype writes a caption that never does.
Oxhype generates a tag set sized to each network from one upload, instead of pasting the same block everywhere.
Captions are generated to fit each platform's current limits, so posts don't get truncated or tags silently ignored.
Brand voice and workspace settings shape the copy, so the tags read as part of the caption rather than a block bolted on the end.
