Sullenvex is the new name for aipornhub, a web-based AI image generator built around anime and hentai art, and I have to open with the bit that matters most: when we went to check the site, it wasn’t loading. The server timed out behind its Cloudflare wall, so none of the public pages (plans, features, examples) could be read. Maybe it’s a blip, maybe it’s gone for good. Either way, what follows is what the tool offered going by what we knew about it beforehand, plus where I’d point you if you want to start generating today rather than refreshing a dead tab.
What aipornhub was before it became Sullenvex
The tool started life as APH, better known to most people as aipornhub (you’ll still see aipornhub.net floating around in old links), and later rebranded to Sullenvex. The pitch was straightforward: an AI porn art generator with a heavy lean towards anime, hentai and waifu-style images. You typed a text prompt, and it gave you back an image. No chat girlfriend, no video, no voice, no Telegram bot. Just pictures.
That narrow focus was honestly its charm. A lot of tools in this corner try to be everything at once, a companion app, a video generator and an image studio stapled together. Sullenvex was one of the ones that just did the one thing, and for anime fans that’s often exactly what you want. It ran in the browser, so there was nothing to install, and it sat in the middle of the pack in our Best Hentai AI Generators list: not a headline act, but a solid enough option that earned its spot.
How the generator was meant to work
Going by what it described, the flow was the classic prompt-box setup. You’d describe the character and the scene in text, the generator would render it as an image, and the output leaned anime and hentai rather than photoreal. The site’s own description went big on “endless possibilities” and “the most advanced AI technology”, which is the standard hype in this category and tells you nothing about how the images actually looked.
That’s the real gap here. Whether the anime faces held up, how fast it rendered, and how well it followed a detailed prompt are the things that would decide whether it’s worth a subscription, and with the pages not loading there’s simply nothing to go on. I’m not going to guess.
Bottom line
Sullenvex costs $15.99/mo and has no free plan; it runs on Web. Where it lands in our rankings: lower half in Anime AI, AI Generators, Image, Generators and Images. Best for: Anime and hentai image fans, once the site is reliably back online. Score 5.1/10 across six weighted criteria; how we rank.
