What is Hevolve AI?
Hevolve AI is a platform for building and talking to multimodal AI agents, with a strong focus on education and language learning. You can browse ready-made agents for speech therapy, spoken English practice, tutoring, and casual conversation, or create your own digital agent that runs around the clock.
The product comes from HertzAI, which builds real-time NLP and computer vision modules for teaching. Hevolve pairs conversational avatars with autonomous curriculum building, assessments, and revision support. It also offers a Mindstory SDK with an OpenAI-compatible API, plus local-first desktop software through Nunba for running agents on your own machine.
It fits educators, therapists, language learners, and professionals who want to package their expertise into an agent. Learners get on-demand help in dozens of languages without booking appointments, while creators can offer pay-per-use access to the agents they build.
Kalos.art

What is Kalos.art?
lib.KALOS.art is a browsable style reference library for AI image generation. It catalogs artist names and art genres organized for Midjourney v5.2, Midjourney v4, SDXL, Stable Diffusion 2.1, and Stable Diffusion 1.5. Each model gets its own library slice so you can see which prompts and references work on the engine you actually run.
Most prompt libraries dump the same artist list for every model. lib.KALOS.art sizes each library to what that model recognizes, from 767 artists on SD 2.1 up to 1,340 on MJ v5.2 and SDXL, with 292 genre and medium categories alongside the artist index. Every artist and genre entry ships with 8 to 11 themed example galleries so you compare outcomes before copying a prompt.
AI art hobbyists and working prompt engineers use it to look up a style, copy a tuned prompt through the built-in copier, and save favorites once they log in. It sits beside the broader Kalos.art marketplace but stays focused on reference browsing rather than selling artwork.
