Scale thumbnail output per client — without scaling headcount
Agency thumbnail production lives or dies on the face-consistency problem. FatThumb solves it: one Person profile per creator client, separate workspaces, and sub-60-second generation that lets you deliver more without hiring more.
How it works
Three steps from zero to upload-ready.
Set up a Person profile per creator client
Create a workspace (or a distinct Person profile) for each client. Their face reference is isolated so you never mix one creator's likeness into another's thumbnail.
Maintain a client's style reference in Inspiration Library
Save the client's best-performing thumbnail as an Inspiration reference. Every new generation references the same proven style — no client briefing required per video.
Generate at scale and deliver
Run multiple prompts back to back, each producing up to 4 variations. Review, star the best, and deliver the 1280×720 PNGs — no Photoshop, no designer time.
Features
Everything you need for the click.
One Person profile per creator
Each client's face reference lives in a distinct Person profile. Face likenesses never bleed between client accounts — a critical quality guarantee for an agency.
More thumbnails, same team
FatThumb's sub-60-second generation changes the economics of thumbnail delivery. A designer can spend a fraction of the time per thumbnail and handle significantly more volume without proportionally more hours.
Client style reference, always available
Save each client's on-brand thumbnail as an Inspiration reference. The AI carries that style into every new generation without requiring a client briefing for each video.
Team workspaces per client
Separate workspaces allow you to grant access to specific team members per client account. Each workspace has its own Persons, Inspirations, and generation history.
Every generation version saved per client
Version history gives you a full audit trail of every thumbnail generated for a client. Go back to a previous direction without regenerating from scratch.
Client-funded generation at cost
With the Lifetime plan and BYO API keys, pass generation costs through to clients at actual API cost with no markup on platform credits.
FAQ
Questions & answers
How does FatThumb handle face consistency across multiple creator clients?
Each creator client gets a dedicated Person profile. Face references are isolated per profile — there is no cross-contamination between clients. When generating for a client, you select their specific profile and the generation uses only that face reference.
Can a team member access a specific client's workspace only?
Workspace-level access control is the intended model. Team members with access to a workspace see only that client's Persons, Inspirations, and history. Granular role-based permissions are on the roadmap for agency-tier.
How do I maintain a client's visual identity without re-briefing per video?
Save the client's best-performing thumbnail as a permanent Inspiration Library entry. Reference it in every generation for that client. The AI maintains their colour, composition, and mood signature — no re-briefing required.
What is the most cost-effective plan for high-volume agency work?
The Lifetime plan with BYO API keys offers the best economics for agencies with consistent high volume. You generate on your own Gemini and OpenAI quota at near-zero marginal cost. Monthly plan subscribers can use credit top-ups for occasional volume spikes.
Can I deliver thumbnails to clients in the right format directly from FatThumb?
Yes. Every download is a 1280×720 PNG — the exact format YouTube Studio expects. Download and deliver directly without post-processing or format conversion.
