Why we built these tools

The internet is full of guides telling you what to do. We wanted utilities that actually do the work. Each tool encodes specific Team AIGN editorial positions:

  • Prompt Generator teaches the 5 structural patterns we’ve found produce best output across models.
  • VRAM Calculator reflects our hands-on findings: RTX 3060 12GB is the floor, 24GB is the comfort threshold.
  • Negative Prompt Builder always includes the safety baseline (child, minor, underage, loli, shota) regardless of positive prompt content.
  • Model Recommendation Quiz reflects our test results: Pony for anime, Flux + LoRAs for realism, Realistic Vision V6 for budget realism.

Free generator (the main attraction)

If you just want to generate now, skip the tools and use our free browser-based NSFW AI generator. No login, no email, EU-hosted. Pony Diffusion, Illustrious, Flux Schnell, and SDXL Lustify on the same widget.
