Hashtag generator for every network
Free tool, no sign-up
Use a few relevant hashtags, sized to the network: up to 5 on Instagram, 1 on Threads, 1 or 2 on X, 3 in a YouTube description. Pick a niche and add your topic to get a ready set for each network, inside its limits.
TallyReel makes the video, writes the caption and hashtags for each network, and posts it.
Make the video from thisHow to use the sets
- Pick the niche closest to your channel, and type what this one video is about. That becomes the first tag.
- Copy the set for each network you post to. Each one is already cut to what that network takes.
- Swap in one tag of your own if a tag does not fit the video. Relevant beats popular.
- Press New mix for the next post, so you are not pasting the same block every time.
Questions
How many hashtags should I use?
Fewer than most people think. Instagram now takes up to 5 a post, Threads takes 1, and on X one or two is the norm. This tool sizes each set to the network for you.
Where do these hashtags come from?
A bank we picked by hand for 20 niches: a few broad tags for reach and more specific ones where the real audience is. Your own topic goes first, as the most specific tag you have.
Does the hashtag generator use AI?
No. It runs in your browser from a fixed bank, so it is free and nothing you type is sent anywhere.
Do hashtags still matter on YouTube?
A little. Put them in the description: the first three can show next to the title. If a video has more than 60, YouTube ignores all of them.
Should I use the same hashtags on every post?
No. Networks can treat the same block on every post as spam. Press New mix for a fresh set, and always add a tag about the video itself.
