Community Teaser thumbnail style

Square teaser with a short line — tease the next upload.

What this style looks like

When you pick the Community Teaser style in Thumby, the AI agent assembles every render around these visual rules — the same prompt scaffolding our system uses to build a CTR-tuned thumbnail in roughly 60 seconds:

square teaser image, single intriguing subject, warm and conversational

Color, lighting, and mood

on-brand palette, soft contrast, inviting and authentic

Composition rules

On top of the look itself, every render in this style follows these layout principles — tuned to keep the thumbnail readable at mobile-feed size and to maximise CTR on YouTube’s 2026 algorithm:

centred square subject, one short conversational line with clear space around it, comfortably inside the edges

Who this style is for

Pick the Community Teaserstyle when your video lives in the niche this look was tuned for. Most users pair it with a one-line topic — the AI agent writes the full prompt, applies the style on top, and ships a 16:9 thumbnail you can download or upscale to 2K / 4K straight away. If you’ve got a face or product photo to anchor the render, drop it in as a reference and the style renders your subject in the look above instead of a generic stock figure.
