AI tag generator
Generate tags, keywords or GitHub topics for an article, README or post, in the case style you need.
Your key stays in your browser.It goes straight to the provider, never to our servers, and we neither log nor keep it. Use a dedicated key with a spending cap, and delete it in the provider's dashboard when you are done.
Input
Result
The result will appear here.Tags decide whether a post appears under the right filter, whether a repository shows up on GitHub's topic pages, and whether a note can be found six months later. Choosing them is a chore people rush, which is how you end up with 'tech' and 'misc'. Paste the article, README or post, choose how many tags you want and the format — GitHub-style kebab-case, snake_case, lowercase, Title Case or #Hashtags — and you get a single line, most central tag first, ready to paste. The prompt prefers specific tags to vague ones ('vector-database' over 'technology'), keeps names in the form people search for, such as kubernetes or pytorch, and folds plurals and spelling variants into one.
How it works
- Adapted from Fabric's create_tags pattern, written for tagging notes in mind-mapping tools: its single-line output, its no-duplicates rule and its instruction to include an author or any tags the text already lists all carry over.
- Kebab-case follows GitHub's topic rules — lowercase letters, digits and hyphens, 50 characters at most — so the result can go straight into a repository's About settings.
- Case styles touch Latin letters only: a Chinese tag keeps its characters and drops its spaces, and technical terms stay in the English form people type into a search box.
- Tagging costs very few tokens, so a small, cheap model does the job; the text and the key still go straight from your browser to the provider, and a restricted key you delete later is the sensible one to use.
Where your data goes
With your own key, what you type and the key go from your browser straight to the provider you choose; neither passes through Hysen Labs. In hosted mode, your text goes through our server to our provider (DeepSeek) and is billed in credits; we keep the token counts and cost of each run for billing, never the text itself or the answer. How the provider handles the text is governed by its own privacy policy.
This tool handles keys and credentials, so nothing about a run is saved, not even to your own history.
About your API key
We do not collect, store or leak your key: it lives only in this page's memory (unless you tick “remember in this tab”) and is gone when you close it. Still, treat any key you have pasted into a web page with care — create a dedicated key with a spending cap for use here, and delete or rotate it in your provider's dashboard when you are done.
What it costs
This tool is free, with no sign-in and no points.
Common questions
- How many tags should I use?
- It depends on where they go. GitHub accepts up to 20 topics per repository; most blogs look cluttered beyond six to ten; a note-taking app needs only enough to find the note again. Generate a few more than you need and delete the weakest.
- Are these SEO keywords?
- They are topic tags drawn from the text, which overlap with keywords but are not the same thing. They describe what the content is about in searchable terms; they say nothing about search volume or competition. Use them as seed terms for a keyword tool, not as a replacement for one.
- Why did some tags come back in English when my text is Chinese?
- Deliberately, for names and technical terms: people search for 'kubernetes' and 'rag', not a translation of them. General topics are written in the language of your text. If you want every tag in Chinese, add a line such as '标签全部用中文' at the top of the input.
The open-source behind it
