How Pictiny picks a thumbnail formula for each niche
Every niche has a different CTR signature. Minecraft viewers reward high-saturation 3D text; podcast viewers reward clean guest headshots; finance viewers reward professional chart overlays. Pictiny tunes its AI prompts and scoring model per niche using the top 1,000 performing videos from the last 90 days.
That means the AI applies the right color palette, the right text length (3 words for gaming, 5–7 for tutorials), and the right composition rules — without you having to know design theory.
