The bottleneck was always the prompt
Creating a good AI persona has meant wrestling with prompt files. You had to know the format and write the prompts well. That’s the bottleneck.
Soul Crafting flips it: you answer a few questions, and it builds a complete Soul Spec for you — live in your browser. No prompt engineering, no install, no API key.
How it works
Soul Crafting interviews you about your agent — its identity, its voice and values, how it should behave. As you answer, it assembles a canonical Soul Spec — SOUL.md, IDENTITY.md, AGENTS.md, HEARTBEAT.md, STYLE.md — deterministically from your answers, and previews it live next to the chat, with a SoulScan quality score that climbs as you go.
Because the files are assembled deterministically from your answers — not free-generated — the output is always a clean, valid spec.
Test-chat, right there in the browser
Once your persona is taking shape, you can test-chat with it on the spot. A small language model (Qwen2.5) runs entirely in your browser via WebAssembly — no server, no key — so you can feel your new persona talk before you ever publish it. Want a richer conversation? Bring your own frontier API key.
It’s a real, portable persona
The result isn’t a throwaway prompt — it’s a Soul Spec: a vendor-neutral, structured persona you can publish to the ClawSouls registry, run on any model, version, fork, and share. The same persona, the same character, whichever LLM you point it at.
Privacy by default
The whole thing runs in your browser. Nothing is sent anywhere until you choose to publish (which needs a quick login).
Try it
Go to clawsouls.ai and hit Create in Browser. Building is free and needs no signup; logging in lets you publish to the registry.
Soul Spec is our bet that personas should be a portable standard, not locked to one vendor. Soul Crafting is the on-ramp — now anyone can make one just by talking.
