Daily vlogs, daily thumbnails — without burning out on design
Publishing a vlog every day means producing a thumbnail every day. FatThumb keeps your face consistent and your visual identity sharp without adding a design task to your already full publishing schedule.
How it works
Three steps from zero to upload-ready.
Set up your Person profile once
Upload 1–5 photos and create your vlog's face reference. From then on, every thumbnail uses your face automatically — no per-video setup.
Describe the day's thumbnail
Write a short prompt describing the shot — the expression, the location, the mood of the vlog. Specificity takes seconds and drives quality.
Generate, star, upload
Get up to 4 variations, pick the winner, download the 1280×720 PNG and upload directly in YouTube Studio. Done before the upload completes.
Features
Everything you need for the click.
Thumbnail in under a minute
Daily vloggers cannot afford a 30-minute Photoshop session per thumbnail. FatThumb produces a finished, correctly sized output in under 60 seconds.
Recognisable across the whole channel
A vlog channel's brand IS the host's face. Person profiles keep your exact likeness the constant — viewers scrolling your channel page always see a cohesive face.
Visual coherence across hundreds of videos
Use the same template or Inspiration reference across your vlog series. Even as topics change, the visual brand stays intact and builds channel recognition.
Near-zero cost for volume publishers
If you publish every day, the Lifetime plan with your own API keys means thumbnail generation costs almost nothing per video — the economics of scale work in your favour.
Compare before committing
Even on a tight schedule, getting 2–4 options and picking the strongest one is better than shipping the first attempt. A/B variations take the same time as a single run.
Every past thumbnail saved
Version history keeps all your past generations so you can go back to a style that worked during a high-performing week and replicate it for similar content.
FAQ
Questions & answers
How do daily vloggers use FatThumb efficiently?
Set up your Person profile once, then treat thumbnail creation as a 60-second step in your publishing workflow: write the prompt while the upload processes, generate, pick the winner, upload to YouTube Studio. The face reference is always ready — you just describe each day's shot.
Can I maintain a consistent thumbnail style across 200+ vlog videos?
Yes. Using the same Person profile, Inspiration reference, and/or template across every vlog ensures visual consistency at any volume. The face stays identical; the specific composition varies per video.
What is the most cost-effective plan for daily publishing?
The Lifetime plan with BYO API keys gives the best economics for daily publishers. You generate on your own Gemini and OpenAI quota at near-zero marginal cost. The one-time fee pays off quickly for a daily publishing schedule.
Can I reference a thumbnail from a good-performing week?
Yes. Upload the thumbnail from your best-performing week to the Inspiration Library and reference it when generating for similar content. The style analysis extracts what made it work so you can replicate that direction.
Does face accuracy improve over time?
The generation quality is determined by the quality of your Person profile photos and your prompt specificity. Adding high-quality, varied-angle photos to your profile and writing detailed prompts gives the best results from day one.
