YouTube Thumbnail Text Generator

Describe your video and get 8 short thumbnail overlay text ideas — the big bold words on the image itself, separate from your video title.

This tool calls an AI model to generate suggestions, so it's rate-limited to keep it free for everyone.

How it works

  1. 1Describe your video topic in a sentence or two.
  2. 2Optionally add your niche for more tailored options.
  3. 3Click Generate and pick the phrase that reads clearly at thumbnail size.

When to use this

  • You've picked a thumbnail image but it feels empty without a short text callout.
  • You're stuck rewording the same 2-3 words fifteen different ways and want fresh angles.
  • You want text that adds new information rather than repeating your title.

A worked example

Describe "I tried living on $1 a day for a week" and you might get back options like "$1 A DAY", "I SURVIVED?", "$7 TOTAL", and "WORST IDEA EVER" — short, punchy fragments rather than full sentences, each one testing a different angle: the constraint, the outcome, the cost, or the regret.

Frequently asked questions

How much text should a thumbnail actually have?+

As little as possible — 2-4 words is the practical ceiling for something a viewer can read at a glance on a phone screen. More than that and it just becomes noise.

Should this text repeat my title?+

No — thumbnail text works best when it adds a different angle or emphasis than the title, not a shortened copy of it. Together they should tell slightly more of the story than either alone.

What font and size should I actually use?+

A heavy, bold weight (not a thin or script font) at roughly 60pt+ relative to a 1280px-wide canvas holds up best once shrunk to feed size — check it with the Thumbnail Preview Tester before finalizing.

Can I use this for Shorts covers too?+

Yes — the same short, punchy phrasing works for a vertical Shorts cover; just compose the text within the vertical frame rather than the horizontal one.
