Thumbo is an AI thumbnail maker built for YouTube creators who post consistently. Upload 3 photos once and every thumbnail features your face. Paste any channel's link to match its style, or start from 50+ proven style packs. Then fix anything by typing it: "make my face bigger", "punchier title". No layers, no prompts, no designer to wait on.
Paste your channel link for a free audit: a report card on your thumbnails, your outlier videos, and ideas for your niche.
Thumbo also maintains a free toolkit with no account needed: a YouTube thumbnail downloader, a 1280x720 resizer with safe-zone crop, a compress-to-2MB tool and a thumbnail font previewer. They run in your browser, so your images never leave your machine.
Free to try, paid plans from $19/month. Built by a solo founder.
