A thread here is meant to run for months. The cast remembers, world files (.wrl) and behavioural mods (.dll) attach to the same scene, a thread can be pinned to a specific version of a kyn, and the story keeps its shape as it grows past anything a single context window could hold.

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.
Bring up to seven more kyns into the thread. Each has their own skills, their own personality and their own opinion of the rest of the party.
An RPG persona is a whole setting in one entry: NPCs, factions, stats and commands, all written in plain language with no code. Attach a .wrl world file and the rules of the place travel with it.
THE MODEL
Long campaigns are where cheap models fall apart. This is what keeps yours coherent.
Gwem, our fast in-house model: quick, solid, great for everyday roleplay. Messages are unlimited on every paid tier.
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.
Yes! You can create completely custom scenarios with your own world lore characters and rules. Our AI adapts to any setting you imagine.
Yes. Energy, Trust, Affection, Arousal, Mood and Pain track from 0 to 100% and shift as the scene shifts, and they feed back into how your kyn responds — push too hard while Trust is low and you find out. Add Auto D20 on top and a roll can genuinely derail a plan, which is what makes it a game rather than a wish-granting machine.
Not with other humans — but you are not alone in the scene either. A thread holds one lead kyn plus up to seven more, each with their own memory, their own voice and their own agenda, and a director pass decides who speaks and when. Party dynamics, arguments, someone sulking in the corner: all of that happens between the kyns, not just at you.
Yes all your adventures are automatically saved. You can pause and continue your campaigns anytime picking up exactly where you left off.
The memory is real and the mechanics are real. Past messages come back by meaning rather than recency, each with the exchange around it, while rolling summaries chain forward so a months-old campaign still knows its own history. On top of that: Auto D20, a live 0-100% stat block that steers behaviour, inner thoughts you can show or hide, up to eight kyns in one scene, and RPG personas that run whole worlds of NPCs and rules from one entry.
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.
