What this tool does

Type a topic, a niche, or a handful of keywords and get a ready-to-paste hashtag pack for five platforms at once: Instagram (full 30-tag cap), TikTok (10–15 with native trending tags like #fyp and #foryou), Twitter (the 2–3 strongest — anything more hurts engagement), Xiaohongshu (5–10 Chinese long-tail), and Weibo (#…# format). The internal dictionary ships 1,100+ real popular tags hand-curated from public sources — top-hashtags.com Instagram leaderboards, TikTok Creative Center discovery, Xiaohongshu explore-page trending, and Weibo's 热门话题榜 — split across 14 niches: food, travel, fitness, fashion, tech, lifestyle, pets, parenting, beauty, business, photography, art, music, gaming. The matcher reads your topic, scores the 14 niches in parallel (3 pts per exact keyword hit, 1 pt per fuzzy/substring), and merges the top-3 pools so a "cozy autumn coffee shop, latte art" prompt blends food and lifestyle tags instead of guessing one. Per-platform copy button, copy-all bundle with platform headers, and a localStorage favorites drawer so you can reuse last week's set. 100% client-side — your topics never leave the browser. No LLM-fabricated tags: every entry below was scraped from public trending data.

Real-world use cases

  • Cross-posting one reel to five platforms before lunch

    You filmed a 20-second latte-art reel and want it live on Instagram, TikTok, Twitter, Xiaohongshu, and Weibo in one go. Type "latte art coffee shop cozy" and you get 30 IG tags, 12 TikTok tags with #fyp, 2 strong Twitter tags, 8 Chinese 小红书 tags, and a #咖啡# Weibo block. Copy-all bundles them with platform headers so each paste lands native, no reformatting between apps.

  • A new fitness coach who has no idea which tags actually work

    You just started posting workout clips and #fitness alone buries you under 500M posts. Type "home dumbbell HIIT beginner" and the matcher scores the fitness niche, merges in lifestyle, and hands back a mix of broad reach tags (#fitnessmotivation) and findable mid-size ones (#dumbbellworkout). The score next to each niche tells you it locked onto fitness at 9 points, not a random guess.

  • Recycling last month's best-performing tag pack

    Your "autumn travel Kyoto" post hit 40k views in October, so you saved that exact pack. A month later you shoot a similar trip and open the Saved drawer, find the set newest-first, and hit its Copy button. No re-running the matcher, no hunting for which 30 tags worked. Saves live in localStorage capped at 50, so a season of winners stays one click away on the same browser.

  • A small brand testing Twitter restraint vs Instagram saturation

    Your social manager keeps dumping 15 hashtags on every tweet and engagement is flat. Type your product topic once and the tool shows Twitter capped at 2 to 3 tags on purpose, citing the Buffer finding that 3-plus tags cost 17% engagement, while Instagram fills all 30. One input, two opposite strategies, so you stop copy-pasting the same tag wall everywhere.

Common pitfalls

  • Pasting all 30 Instagram tags onto a tweet. Twitter punishes that with -17% engagement past 3 tags. Use the Twitter card's 2 to 3 picks instead.

  • Copying the Weibo block into TikTok without stripping the trailing

  • Trusting the tag pack blindly for a sensitive account. Instagram's shadow-ban list shifts weekly, so spot-check two or three tags via Instagram search before posting a high-stakes campaign.

Privacy

Everything runs in your browser. The topic you type is matched against a local dictionary in JavaScript and never sent to any server, and it is not written into the URL. Saved tag packs live only in this browser's localStorage, capped at 50 and removable anytime by clearing site data. Nothing about your topics, niches, or saved sets leaves your device.
