Generate punchy 3-5 word thumbnail text overlays. The big text on a YouTube thumbnail accounts for ~60% of the click decision (the rest is image + face). Pick a curiosity style and channel niche, get 6 A/B-ready variants - each fits the 3-5 word sweet spot, all-caps, no full sentences. Live preview shows roughly how each renders against a black thumbnail backdrop.

Canva ($15/month) and Adobe Express ($9.99/month) are visual editors - they do not generate the TEXT, they help you LAY OUT text you wrote.
