Great videos lose to forgettable thumbnails.
It’s not the algorithm and it’s not your content — if people don’t click, they never watch.
Lost in the feed.
A flat, busy thumbnail blends into the wall of videos around it. Viewers scroll past in under a second.
Hours per design.
Every upload means another evening in an editor, cutting out faces and nudging text. Time you could spend on the video.
Off-brand and inconsistent.
Colours, fonts and faces drift from video to video. Subscribers never learn to spot your uploads.
Everything you need for thumbnails that get clicked
From idea to thumbnail in one chat.
Tell the AI agent what the video is about. It asks the right questions, proposes a design, and generates it once you approve.
Prompt to thumbnail.
Describe the video in plain words — get a finished, on-brand design. No blank canvas, no templates to fight.
Edit by asking.
“Make the text bigger, swap to yellow.” Every change lands as a new version — the original is never lost.
Video to thumbnail.
Paste a YouTube link and import the transcript. The agent finds the strongest hook and builds the thumbnail around it.
Your face. Your brand. Every time.
Save who you are and how your channel looks once — every thumbnail follows it.
Characters.
Upload a few photos once and feature yourself — or your whole cast — in any thumbnail, with any expression.
AI agents for your channel.
Train an agent on your niche, audience and brand colours. Every new project starts on-brand.
Recreate any style.
Grab any YouTube thumbnail and use it as a style reference for layout, colour and type — the design is yours.
Reference library.
Keep logos, products and backgrounds in buckets and @mention them in any project.

An AI YouTube thumbnail maker. You chat with an AI agent that knows your channel, your face and your style — it proposes a thumbnail, you approve it, and you refine it just by asking.
No. Describe the video in your own words — the agent handles layout, text, colour and lighting. You ask for changes the same way.
Yes. Add yourself once under Characters with a few photos, then feature yourself in any thumbnail with any expression.
Monthly plans include credits, and each AI action uses credits based on its real cost (1 credit = $0.01). Not ready to subscribe? Try it with a small one-time trial pack. Or bring your own API keys with Lifetime access.
Plan credits refresh at each renewal and don’t roll over. Subscribers can add extra credit packs anytime.
