YouTube tag generator
Specific first, general last
You get ten to fifteen tags, lowercase, one to four words each, ordered from the ones that describe this video exactly to the ones that only place it in a category. The order is the useful part: if you have more than you want, cut from the end, and what is left still says what the video is.
One list against one budget
YouTube's tag field takes a comma separated list with 500 characters across all of the tags together, not per tag. So the answer is one row to copy rather than fifteen, with the number of tags and the characters used shown beside it.
What tags can and cannot do
Tags are a weak signal on YouTube now. A specific title and a description that says what the video is do far more, so write those first and treat tags as the last step. No hashtags, no punctuation, no duplicates, and nothing that is not about the video you described.

This tool also runs over MCP, so Claude, Cursor or another MCP client can use it against your own channel. See the MCP page.
Questions about this tool
Can it add to the tags a video already has?
Yes. List the existing tags in the box and it is told to suggest only ones that are missing, rather than handing back the ones you have. Inside Runsheet the video editor does this for you and adds the suggestions to the end of the field without touching the tags already there.
Does it need an account?
Yes, and only because each generation costs real money to run. A free account gets 3 drafting runs a day, shared across the drafting tools, and needs no card. The character counter, the line break tool and the bold text tool need no account at all, because they run entirely in your browser.
Will it make things up about my video?
It is instructed not to, in every case: no invented statistic, no claim about how the video will do, no timestamp or sponsor you did not mention. It only has what you type, so the more specific you are the less room there is for it to guess.
Does this decide anything about my channel?
No, and that line is deliberate. Runsheet uses a model to write copy and never to produce a finding. Every number it reports about your channel is measured, uses medians rather than means, and refuses to answer when the sample is too small. Nothing generated here touches that.
Can I run YouTube tag generator automatically?
Yes. Every tool here is also exposed as an MCP tool, so Claude, Cursor or anything else that speaks MCP can run it against your own channel. How to connect one is on the MCP page, https://runsheet.buildifyapp.in/mcp.
Do you keep what I type?
The text you enter is sent to Google's Gemini API to produce the answer and is not stored by Runsheet. What is recorded is that a generation happened, so the daily allowance can be counted.
