Featured image prompts
Copy, paste, generate. Each prompt is tested on the model it targets, with the parameters that make it sing.
Cinematic golden hour portrait
A warm, atmospheric portrait with soft rim lighting and shallow depth of field. Reliable for character shots that feel like film stills.
Editorial illustration with integrated headline
A flat, modern editorial illustration with a real headline rendered legibly inside the image. DALL·E 3's text rendering is its standout strength.
Minimalist logotype with custom mark
A clean, geometric logo with a custom mark and legible wordmark. Ideogram is unmatched for logo work because of its text rendering and sharp shape control.
Painterly concept art landscape
A wide, painterly landscape in the style of a feature animation background. Stable Diffusion XL with the right LoRA gives you control Midjourney won't.
Studio product shot on textured concrete
Clean, commercial-grade product photography with soft studio lighting and a quietly luxurious concrete surface. Works for skincare, electronics, or any premium SKU.
Curated, not crawled.
Every agent and prompt on Kritak is hand-reviewed before it ships. Each agent comes with a curator note covering what it does well, where it falls short, and who should use it. No surprises.
