⚡ An AI thumbnail agent for high-CTR YouTube covers.
This agent turns your video description into YouTube-ready thumbnails. Choose style, aspect, and quantity, or use 10+ one-click starters. Upload a portrait to blend in; safe zones stay intact. Made for creators who need fast, consistent covers.
🟣 10+ one-click starters: users who don’t know what to write can begin with common scenarios instantly.
🧠 Multiple generation modes: built-in styles, AI creative mode, and user-defined channel style.
🧑🎤 Portrait-ready: upload yourself or a guest; auto cutout + outline + style matching.
📐 Safe-zone first: headline and subject are placed inside visible areas for TV/mobile.
⚡ 30-second multi-variants: generate 1–3 options at once for A/B testing.
✨ Even if you can’t write prompts, you can still get thumbnails that look like your channel and actually get clicked.
Task: Draft a description for a new thumbnail about “AI Excel automation in 10 minutes,” highlighting one striking visual hook and the promised transformation.
Constraints: use one sentence; include the value number “10 minutes” and one emotional adjective; avoid mentioning colors or layout keywords.
Example: “Teach 5 AI-driven Excel tricks that automate spreadsheets for beginners and promise a 10-minute glow-up for their workflow.”
Task: Describe a volcano expedition thumbnail that emphasizes AI-guided navigation and a dramatic reveal moment.
Constraints: mention time pressure, the environment, and an AI element; keep it under 25 words; no technical parameters.
Example: “Race a stormy midnight trek to the lava rim as an AI map glows in-frame, promising viewers the exact moment the crater erupts.”
Task: Write a thumbnail description that teases a shocking stock drop and the secret chart pattern decoded on-camera.
Constraints: must include a number (like -12%), one question cue (“how/why”), and an action verb; avoid style jargon.
Example: “Expose why the Nasdaq plunged 12% overnight and show how our AI dashboard caught the warning signal before anyone else.”
