| Platform | Limit | What works |

| 5 per post or Reel (since December 18, 2025) | 3–5 specific tags in the caption | |
| TikTok | Counts toward the caption length | 3–5 relevant tags |
| YouTube | Over 60 and all are ignored | The first 3 show above the title |
| No hard limit | 3–5 | |
| X | Counts toward 280 characters | 1–2 |
| Twitch | 10 tags per stream | Game, language and style tags |
Hashtags mostly help a platform understand and file your post; they don't add reach on their own. Mix one broad tag for the topic, two niche community tags and two that describe this exact post.
How it works
Describe the post in plain words. An AI model suggests about 30 tags in three groups, and the best mix for your platform is pre-selected. Tap to add or remove, then copy. Suggestions are cached, so popular topics come back instantly. Check that each tag actually fits your post before you use it.
Check your caption length with the caption length checker, and research a video's keywords with the YouTube tag extractor.
Frequently asked questions
How many hashtags can you use on Instagram?
Five per post or Reel. Instagram cut the limit from 30 to 5 on December 18, 2025, and the limit counts tags in the caption and comments together.
Do hashtags still work?
They help platforms categorize and surface posts in search and topic pages, but they don't boost reach by themselves. A few relevant tags beat many generic ones.
What are the best hashtags for Reels or TikTok?
Specific ones that describe the video and its community, such as #homeworkout or #budgettravel, rather than generic tags like #fyp or #explore.
