Generates 6 punchy 3-5 word thumbnail TEXT OVERLAY options. The big text on a YouTube thumbnail accounts for ~60% of the click decision (the rest is image + face). Pick a curiosity style (shock value / number-led / question / VS comparison / hidden-secret / warning / result-payoff) and channel niche. Live preview renders each variant against a black thumbnail backdrop in 4 high-CTR colors (yellow / red / white / cyan).
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. TubeBuddy ($7-49/month) does thumbnail A/B testing but you still write the text yourself. Free.ai writes the text overlay; pair with Canva or our /design/youtube-thumbnail/ for the visual composite.
Yes — Qwen 2.5 7B on our GPUs, ~150 tokens for 6 overlays. Free signup gets 10,000 tokens — ~60+ batches of 6.
Mobile YouTube thumbnails are tiny — usually 320x180 pixels in the recommended-feed sidebar. Text past 5 words becomes unreadable at that size. The 3-word sweet spot maximizes legibility + impact. Mr Beast, Marques Brownlee, and Veritasium all average 2-4 words on their thumbnails per analysis of their top 100 videos.
Shock value (bold claim + surprise), Number-led (digit-first), Question, VS / comparison, Hidden / secret, Warning / mistake, Result / payoff. Each has a dedicated system prompt.
The preview shows 4 high-CTR colors: yellow (proven highest CTR in 2024 Mr Beast analysis), red (urgency), white (clean / educational), cyan (tech / gaming). The TEXT itself does not depend on color — pick whatever color matches your channel branding when you composite the final thumbnail in Canva/Photoshop.
No — first batch free. Sign up for 10K tokens.
The system prompt bans clickbait misdirection — the overlay must reflect what the video actually delivers. Bold language is fine; LYING is not. YouTube's algorithm punishes thumbnails that do not match content (high click-then-bounce kills CTR rank).
Yes — that is the design. YouTube Studio's Test & Compare feature lets you serve 3 different thumbnails to different viewers and pick the winner after 14 days. Generate 6 variants, pick your top 3, A/B test them in Studio.
The generator does not include emojis (you cannot reliably color them in graphic editors and they look small at thumbnail size). Add them yourself in Canva if you want them. Most top creators stick to text + face + bold visual element.
Yes — type your niche in the niche field. Tech channels lean on number-led + hidden-secret styles. Gaming channels use shock + result. Fitness uses transformation. Education uses question + warning. The system prompt adjusts examples per niche.
Yes — POST to /v1/chat/ with the thumbnail-text system prompt (inspect template source). Useful for thumbnail-design pipelines or bulk-A/B-test generation for content studios. Bearer auth, monthly limits. Docs at /api/.
