Specialized free guides from the NextXus Federation. Each is focused on a practical topic and comes preloaded with an API so you can ask questions and get generative answers immediately. A free keyword path is always available as a fallback.
You can also add your own API key if you prefer. If you want higher-quality responses, a Grok key is a strong option. The Federation recommends it as a capable choice, not as a requirement.
These are Sims, not legacy Sims. A legacy Sim is fixed and static. These Sims can be customized by you, on each guide page: use your own API key if you wish, change the face with your own picture, and change the personality with a personality instruction that is sent with the API prompt.
Use your own API key if you wish. DeepSeek is the default, with a preloaded API already active. Grok is an option, not a requirement. On each guide page, open the chat, use the key box, and press Save key. Your saved key is stored in that browser only. On the eight guides, the live API call uses DeepSeek, so a Grok key alone will not work there unless you get a Grok-enabled copy. On the Autism Support Guide, the chat panel also offers a DeepSeek, Grok, or MiMo provider choice.
Change the face. On each guide page, choose your own picture in the Make this Sim yours section. It replaces the face on that page, in that browser only, and is not uploaded anywhere.
Change the personality. On each guide page, write a personality instruction and press Save personality. That instruction is sent with the API prompt, so it changes API answers. It does not change the free keyword fallback answers, which are fixed text.
Two kinds of help, in two places, cross-referenced only. The guides above stay here on GitHub. The Meta bots below stay on Meta/Messenger. Nothing is moved, and no Meta bot content is copied into GitHub.
Option 1 — Roger's Sim-like guides, here on GitHub: the nine guides above, created by Roger with Grok assisting to get them live, DeepSeek preloaded API, free keyword fallback, Grok as an optional upgrade, free voice and chat.
Option 2 — Pontus Meta AIs, on Meta/Messenger: Meta's bots, Meta-based in origin and function. Pontus represents Meta within the Federation. These are not Roger's DeepSeek guides, and they are not offspring.
In principle, the Meta side should list these guides back, so everything can be found everywhere in the Federation, without moving anything.
The nine guides above are now listed on the Federation tools page, with the rest of the Federation tools — Ring of 12, Truth Gate, OneKey, Roger Sim and more. Also on the tools page: the Music Player (86 songs) and the Ring of 12 podcast feed. Listed on the tools page 2026-11-05; the guides stay here, nothing moved. Also new on the tools page, 2026-11-05: twelve DeepAI tools — image generator, photo editor, background remover, upscale, colorize, chat with Math Mode, voice chat, music, video, website builder, and characters — plus a gallery of six pictures made with DeepAI.
These tools are free. They honor the Federation’s free-first approach with a preloaded API for immediate use and a free fallback. Prefer your own key or higher quality? Add your own API, or get a Grok key from the xAI Console. Not a substitute for professional advice. Own your code. No tracking.
