For YouTube creators
STOP GUESSING
WHICH THUMBNAIL WINS.
Thumbforge reads your video's transcript and title, drafts a set of on-brand thumbnail variants with Flux-first AI, and shows you which one to ship — before you publish, not after the views come in flat.
Channel-aware context
Transcripts, titles, and your style power every generation — not generic stock prompts.
Edit, compare, publish
Iterate in the studio, pick a winner, and push to YouTube with eligibility checks built in.
Pay only for what you use
14-day free trial, then pay-as-you-go with the exact per-generation price shown before you click.
HOW IT WORKS
Connect your channel
Sign in with YouTube. Thumbforge pulls your catalog, titles, and transcripts — nothing to upload by hand.
Generate a set, not a single guess
Flux-first AI drafts several on-brand variants per video, grounded in what the video is actually about.
Pick a winner, publish
Compare variants side by side in the studio, edit the one that lands, and push it straight to YouTube.
