Auto D20 on every message
Turn it on and a twenty-sided die is rolled into every exchange. Your kyn plays the result — a fumble derails the seduction, a crit changes the night.

Tag Fields and World Architecture
Structure your RPG personas with specialized tag fields: Physical traits for image generation, Clothes for thematic outfits, Location for setting context, and Identity for universe logic. Each field builds coherent roleplay experiences with consistent world rules.

Factions, Stats, and Inner Monologues
Design complex character interactions with faction systems, custom stat tracking, and inner monologue mechanics. Create competing groups, progression systems, and psychological depth through behavioral patterns the AI maintains throughout roleplay.

Chat Examples as Pattern Engines
Train your AI systems through carefully crafted chat examples that demonstrate format, tone, and behavior patterns. These examples teach the AI how to handle commands, display stats, manage multiple characters, and maintain consistent world rules throughout roleplay.
.dll behaviour mods and .wrl worlds
A .dll is a behavioural mod you can attach to any kyn; a .wrl is a world file. Both are first-class citizens of a thread's Context tab, sitting alongside the kyns themselves — so a system you build once can be dropped onto somebody else's character without rewriting either of them. This is the modding layer, and it is the part of Soulkyn nobody else has.

Mechanics, not adjectives
The engine your system runs on top of, all of it already there.
Live character stats
Energy, Trust, Affection, Arousal, Mood and Pain track from 0 to 100% and move as the scene moves. They are not decoration — they steer how your kyn answers next.
Inner thoughts, on your terms
Your kyn's reasoning renders inline as inner thoughts, with a three-way switch: collapsed, always open, or hidden. Any single reply can also be regenerated with deeper reasoning when it matters.
Your roleplay format
Asterisks for actions, or Discord-style italics. Pick the convention you already write in and the kyn writes back the same way.
Unlimited versions
Every edit makes a version and nothing is lost. Threads pin the version they were started on, and you can move a thread to another one.
Up to 8 in a scene
One lead plus up to seven additional kyns in the same thread, each with their own memory and their own agenda.
THE MODEL
Two tiers, one honest answer
A persona that runs a world has to hold rules, factions and a dozen NPCs in its head at once.
Standard chats
Gwem, our fast in-house model: quick, solid, great for everyday roleplay. Messages are unlimited on every paid tier.
Deluxe chats — GLM 5.3
Deluxe runs on GLM 5.3, an Opus-class model — the size class of the biggest frontier assistants. Soulkyn self-hosts a 753B-class frontier model on private clusters, which is exactly why it can be unlimited. Deeper memory, sharper dialogue, characters that keep track of the story.
Deluxe and Deluxe Backer text chat switches to GLM 5.3 automatically — there is nothing to enable. It does not apply to voice calls, which stay on the standard model.

RPG Character Creation FAQ
What makes RPG personas different from regular characters?
RPG personas are behavioral systems that can represent multiple characters, factions, game mechanics, and world rules within a single AI entity. Unlike individual characters, they manage complex interactions, stats, and narrative systems through language-based design.
How do I create effective chat examples?
Chat examples should demonstrate specific formats, behavior patterns, and system mechanics you want the AI to follow. Include examples for stat displays, multi-character interactions, faction dynamics, and special commands. Each example teaches the AI functional logic rather than just dialogue style.
Can I build mini-games within personas?
Yes! You can create any game mechanic through language description and chat examples. Build magic systems, combat mechanics, progression systems, economy simulations, or social dynamics. The AI follows patterns you establish through clear rules and consistent demonstration.
What are .dll and .wrl files?
A .dll is a behavioural mod — a rule set, a mechanic, a way of speaking — that attaches to any kyn without changing that kyn. A .wrl is a world file that sets the rules of the place a scene happens in. You link them from a thread's Context tab, next to the kyns and scenarios already in the room, and you can stack them. It means a mechanic you designed is portable: build it once, apply it to any character, share it.
How do tag fields work in RPG personas?
Tag fields structure your persona data: Physical describes traits for image generation across multiple characters, Clothes defines thematic outfits, Location sets the world context, and Identity establishes universe logic that all NPCs understand and follow consistently.
What are some example RPG persona types I can create?
You can create magical academies with curriculum systems, prison complexes with hierarchy dynamics, taverns with social mechanics, post-apocalyptic bases with survival elements, fantasy kingdoms with political intrigue, or even abstract systems like Linux terminals or spell-casting frameworks.
Are there real dice rolls in the roleplay?
Yes. Auto D20 rolls a twenty-sided die into every message when you enable it, and the kyn plays whatever comes up. Combined with the live stat block — Energy, Trust, Affection, Arousal, Mood, Pain — a scene can genuinely go wrong, which is the whole point.
