AI Thumbnail Maker

Upload a video, get four scroll-stopping thumbnails — you, cut out and dropped into cinematic AI scenes with a headline built to get the click. No template picking, no caption editing.

  • 4 in one go
  • Your face in the scene
  • AI headlines
  • YouTube · Shorts · Square

Made from your actual video

Not clip art — you, in the scene.

Most thumbnail tools hand you a template. This one reads your video, cuts you out of it, and builds a grid of finished thumbnails around you.

You, in the scene

We find the best frames of you in the video, cut you out cleanly, and composite you into each generated scene — so the thumbnail is unmistakably your video, not stock art.

A grid of looks, one click

Every batch spans a balanced mix of realistic cinematic shots and bold themed styles — 3D, anime, comic, neon cyber, watercolor — each with its own camera angle and colour palette.

Headlines that get clicks

The AI reads your video and writes punchy, curiosity-driving headlines — or bakes in the exact line you type. Big, legible, and built to stop the scroll.

Wide, vertical, or square

Render 16:9 for YouTube, 9:16 for Shorts and Reels, or 1:1 for feeds. Same video, the shape you need.

From video to thumbnail in three steps

1

Upload your video

Drop in an MP4, MOV, or WebM. We read the clip and quietly transcribe it so the AI knows what your video is actually about — no template picking, no caption editor.

2

Add a headline (or don't)

Type the headline you want on every thumbnail, or leave it blank and let the AI write a scroll-stopping variation for every tile tuned to your video.

3

Pick & download

Four fully-rendered thumbnails stream in — your face cut out and dropped into cinematic, 3D, comic, and neon scenes. Select the ones you love and download in one click.

One video · a grid of thumbnails

Give it a video. Get the click.

Frequently asked questions

How does the AI thumbnail maker work?+

Upload a video and it's transcribed so the AI understands the topic. It then extracts the best frames of you, cuts you out, and composites you into four fully-rendered scenes, each with its own style, camera angle, colour palette, and a bold headline. You pick the ones you like and download them.

Do I have to edit captions or pick a template first?+

No. This is the thumbnail maker on its own — no template selection and no caption editor. Upload, optionally type a headline, and generate. (If you also want captions, one click opens the same video in the full Moonshot editor afterwards.)

Is there an option that doesn't use AI image generation?+

Yes. On Creator and Pro, Key frame mode pulls strong real frames from your video and lets you place a bold headline on top. It does not spend an AI thumbnail generation credit.

Can I use my own headline?+

Yes. Type a headline and it's baked into every thumbnail. Leave it blank and the AI writes a different headline for each tile tuned to your video. It works on clips with no speech too — just add a short headline so the AI knows what it's about.

What aspect ratios can I make?+

16:9 for YouTube, 9:16 for YouTube Shorts / TikTok / Instagram Reels, and 1:1 for square feeds. Switch shape and regenerate any time.

Is it free?+

AI and key-frame thumbnails require an active Creator or Pro plan. Each paid account gets one lifetime AI thumbnail preview with four options. After that, a $6.99 pack — or ₹599 in India — adds 5 non-expiring generations.

Are my videos kept private?+

Yes. Uploads are processed privately, never shared or used to train models. Only upload content you have the rights to.
