Kalos.art vs Retune

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.

Retune lets you build custom AI chatbots without writing code, train them on crawled website pages or uploaded files, and embed a branded chat widget on your site. You can spin up bots for customer support, sales qualification, or internal knowledge lookup, then publish them when you move beyond personal testing. It covers bot building, data training, deployment, and widget styling in one workflow rather than stitching together separate tools.

Where Retune stands out from generic chatbot builders is how it packages training and publishing limits across clearly separated tiers. Personal bots can run with unlimited messages on the Launch plan, but publishing to the web caps at 5 bots on Grow and scales up to unlimited on Max with whitelabeling. That tiered split matters if you are comparing it to tools that charge per message or per seat instead of per published bot.

Retune fits agencies, SaaS teams, and small businesses that want branded AI assistants trained on proprietary docs or crawled site pages. The homepage now opens with a short growth diagnostic that routes visitors toward the bottleneck they care about, whether that is booking calls, closing sales, or reducing churn, before they sign in to build bots.
