Titles, tags, captions

Don't sound like a caption bot.

Paste what the clip is about — a script, a transcript, a one-line brief. You get a YouTube title (100 characters), a description that spends the first 150 characters on the search phrase, tags under 500 characters, and TikTok / Instagram / X copies that do not sound like a model wrote them. Character counts are checked. Rank data is not invented.

How it works

Three moves.

Paste the clip

Script, transcript, or three sentences on who, where, and what moves.

Name the search phrase

Optional. If you skip it, the title is written from the footage, not from a guessed keyword.

Take the fields

Copy into YouTube / TikTok / Instagram. Counts are already under the limits.

Limits

What each field can hold.

These are the platform caps. The tool stays under them. It does not invent YouTube search volume.

YouTube title — 100 characters. Front-load the search phrase; the rest is a hook, not a slogan.
YouTube description — 5,000 characters. The first 150 show above the fold — that is the SEO paragraph.
YouTube tags — 500 characters total. Specific phrases beat a dump of every related word.
TikTok caption — 4,000 characters. Three to five hashtags; the first line is the hook.
Instagram caption — 2,200 characters. First line before the fold; hashtags can sit at the end.
X post — 280 characters. One line plus two hashtags, or none.

FAQ

Short answers.

Is this TubeBuddy or vidIQ?

No. Those tools read live YouTube search volume and rank. This page writes the listing from your clip. It does not scrape autocomplete or invent a search-volume number.

Where do the tags come from?

From the footage you described, plus the search phrase if you gave one. They are not a live YouTube tag API. If a tag is generic (“video”, “viral”), it is dropped.

Will it sound like ChatGPT?

The brief is to match how you already write, keep sentences short, and avoid filler (“unlock”, “dive in”, “in this video”). You can ask it to match a past caption.

Shorts, Reels, TikTok — same fields?

Same job, different limits. Pick the platform in the panel. YouTube Shorts still uses a title and description; TikTok and Instagram are caption-first.

Does it make the thumbnail?

Not this page. Generate the still with the first-frames tool, then come back and write the listing to match it.
