AI YouTube Thumbnail Generator
Give it a video title and a hook. The canvas drafts thumbnail concepts, renders a batch of variants, and lays in the text so you can pick a winner.
- A batch of thumbnail variants per title
- Concept, key art, and text composed in one pass
- A/B a few looks without opening an image editor
One canvas
for the whole craft
Image, video, audio, and text on a single node-based canvas — with the editing tools you rely on wired in right next to the model calls.

Edit where you generate
Mask, retouch, extend, relight, upscale, layer, and composite. The editing tools you reach for, wired into the same canvas as the model calls.
Watch every node render
Outputs stream in as nodes finish. Inspect any frame, swap a model, re-run from that node down.
Your keys, provider prices
Bring your own keys for FAL, KIE, OpenAI, Anthropic, Gemini, Replicate, and the rest. The bill comes from the provider, not from us.
Image, video, audio, text
Flux, Seedance, Wan, ControlNet, Whisper, ElevenLabs, Suno — all of it on one canvas, under their real names. No renamed mystery models.
Frequently asked questions
Can it match my channel's style?
Yes — describe the style in the prompt node, or feed a reference image, and the batch follows it.
How many variants do I get?
As many as you set on the batch node. Render a handful, compare them on the canvas, and export the best.
Is it free?
NodeTool Studio is free and open source. You bring your own image-model key and pay that provider directly.
