About YouTube Title, Description & Tags Studio

The YouTube Title, Description & Tags Studio is a free, browser-based workspace for writing a video's upload metadata with YouTube's real platform limits checked live as you type. The title field counts against the 100-character hard cap and marks the ~70-character point where search results truncate, with ALL-CAPS and repeated-word warnings. The description shows exactly what viewers see above the fold before 'Show more' (about the first 157 characters or 3 lines) and detects links and hashtags. Tags are built as chips with a per-tag 100-character check and a live meter for the ~500-character total budget, and the hashtag field enforces the 15-hashtag rule (over 15, YouTube ignores them all). A mock search-result card previews how your listing will render, your draft auto-saves to this device, and an optional local-AI layer (desktop only) can generate title options, a description draft, tags, and hashtags — all without anything ever leaving your browser.

How to use YouTube Title, Description & Tags Studio

  1. Type your title and watch the counter — the bar marks ~70 characters where search results cut it off, and warnings flag ALL-CAPS or repeated words.
  2. Write the description; the 'above the fold' box shows exactly what viewers see before clicking 'Show more', and detected links and hashtags are counted for you.
  3. Add tags with Enter or commas — each chip is checked against the 100-character per-tag limit, and the meter tracks the ~500-character total budget.
  4. Add hashtags; the tool reminds you the first 3 in your description show above the title, and warns before you cross 15 (when YouTube ignores them all).
  5. Check the search-result preview card to see the truncated title and 2-line snippet the way YouTube renders them, then copy each field — or 'Copy all' for one paste-ready block.
  6. Optionally, on desktop, paste your topic or script into the AI box to generate 8 title options, a description draft, tags, and hashtag suggestions from a local model — click any suggestion to apply it.

Frequently asked questions

Are my titles, descriptions, or drafts uploaded to a server?
No. Everything runs in your browser — every counter and check is computed locally, drafts auto-save to your device's localStorage, and even the optional AI generation runs on a local model (in-browser or your own Ollama/LM Studio server). Nothing you type ever leaves the tab.
What is the 100-character title limit, and why the ~70-character marker?
YouTube hard-caps titles at 100 characters — the tool won't let you go past it. But search results and most surfaces truncate titles around 70 characters, so the counter bar marks that point; keeping your hook in the first ~70 characters ensures it survives truncation.
How does the 500-character tag budget work?
YouTube limits the entire tags field to roughly 500 characters total (commas between tags count), with each individual tag capped at 100 characters. The chip builder sums your tags live, refuses a tag that would blow either limit, flags duplicates, and lets you copy the whole comma-separated list in one click.
Do tags still matter for YouTube SEO?
Honestly, only a little. YouTube has said tags play a minimal role in discovery — title, description, thumbnail, and watch time matter far more. Tags mainly help with common misspellings of your topic. Fill them in since the field exists, but spend your effort on the title and the first lines of the description.
Does the AI part need an internet connection?
Only once, and only on desktop: the in-browser model downloads a single time (a few hundred MB, then it's cached), or you can connect your own local server like Ollama or LM Studio. After that, generation runs entirely on your machine — your topic, script, and drafts are never sent to any cloud service.
