Identity · Memory · Portability
One engine. Every product that remembers.
SoulPrint Engine is the platform underneath SoulPrint Passport, KidSprint and Foundry. Same identity, same memory, same portability — each product just points it at a different job.
The family
Built on one engine
Every product starts from the same place: a memory that belongs to the person using it. Different audiences, different jobs, one thing underneath.
Live in betaSoulPrint Passport
soulprintpassport.ai
Your AI, remembering you. One memory that follows you across ChatGPT, Claude and every agent tool you use, so switching tools never resets the thread.
What is Passport?
In developmentKidSprint

foundryagents.ai
A crew of 169 specialist AI agents for your team. Brief them once on your mission, tone and people, then work in direct or group chat.
What is Foundry?Underneath
What the engine actually does
Six systems, shared by every product. Build them once and each new product starts with the hard part already done.
SoulPrint PassportKidSprintFoundryMemory engine
Holds what matters, with provenance. Every memory keeps where it came from and what changed when you corrected it.
Assessment engine
Patent pendingBuilds the first real picture of you, so a product is useful on day one instead of week three.
Portability layer
Moves that memory between tools. A browser extension for chat, an MCP server for agents and dev tools. Same memory, either door.
Identity layer
Tone, format and depth follow the person, not a settings menu. The product adapts to you, not the other way around.
Imprint system
Portable personas that change how the AI shows up — voice, tone, priorities. Your profile stays constant underneath.
Dynamic Intelligence
Reads the question and picks the model. Different tasks go to the AI that handles them best, and it tells you which one it chose.
Imprints
One you. Every mode you need.
Your profile is the constant. An imprint changes how the AI shows up for the moment — the voice, the tone, the priorities, how hard it pushes back. Swap it per conversation, or set one for a whole project.
Professional
Business Coach
Leads with questions before answers. Challenges the idea, not the person.
Professional
Career Advisor
Maps the path, names the tradeoffs, tells you what the move actually costs.
Creative
Creative Writer
Finds the voice already in the draft and cuts everything that isn't it.
Creative
Storyteller
Turns a flat account of events into something with a shape and a turn.
Education
Study Buddy
Goes at your pace and checks you understood before moving on.
Education
Math Tutor
Shows you the step you missed instead of doing the problem for you.
Personality
Tough Love Coach
Says the thing your friends are too polite to say.
Personality
Zen Master
Slows the question down until the answer is obvious.
Project imprint
Scoped to one project. Applies only inside it.
Default imprint
Applies everywhere, unless a project overrides it.
Your SoulPrint
Who you are. Never replaced, never flattened.
Fifty imprints ship with the engine, across five categories, and SoulPrint Passport uses them today. Anything you don’t see, you describe in a sentence and build.
Dynamic Intelligence
You don’t pick the model. The engine does.
Every question gets read before it gets answered. The engine works out what you’re actually asking for and routes it to whichever AI handles it best — then tells you which one answered, and why. Every product in the family routes through it.
| You ask | Routes to | Because |
|---|---|---|
| Explain quantum physics to me | GPT-5.2 | Reasoning-heavy question |
| Write me a love poem | Claude Opus | Writing and voice |
| What's the weather today? | Sonar Pro | Needs live web search |
| Design a logo for my brand | Seedream | Accurate text rendering |
| A photorealistic sunset over water | Nano Banana | Photoreal image generation |
| A person talking to camera | Wan 2.6 | Lip sync |
| Cinematic drone shot over a coastline | Sora 2 | Cinematic video quality |
The confidence score and the reason come back with every routed question. Routing stays visible on purpose — you can always see where an answer came from.
Coverage
Runs across the tools you already use
We sit across the AI tools, not above them. Keep the ones you like and carry your memory between them. SoulPrint Passport is the product that connects to them today.
Anything that speaks MCP can connect. There is no SoulPrint mobile app — the platforms you already have on your phone are the mobile experience.
The engine is ours. The memory is yours.
Straight answers
Questions people actually ask
The engineIs SoulPrint Engine something I can buy?
No. The engine is the platform, not a product. SoulPrint Passport, KidSprint and Foundry are the products built on it — those are what you sign up for.
The engineWhat do the three products actually share?
One memory, one identity and one routing layer. Your profile is stored once, and each product points that same engine at a different job.
SoulPrint PassportWhat is SoulPrint Passport?
Your AI, remembering you. It carries one memory across ChatGPT, Claude and every agent tool you use, so switching tools never resets the thread.
SoulPrint PassportWhat does Passport cost?
It is free during beta — no card and no limits. After beta it is $9 a month or $90 a year, and the first fifty founding members keep lifetime access.
SoulPrint PassportWhich AI tools does Passport work with?
ChatGPT and Claude are connected today. Gemini and Perplexity are coming. Hermes, Claude Code, Codex and Cursor connect through MCP right now.
KidSprintWhat is KidSprint?
A safe AI learning sidekick for kids. It adapts to how your child thinks and works at their pace, encourages curiosity instead of handing over answers, and keeps parents in the loop. There is a page about it here on this site.
KidSprintWhen can I use KidSprint?
Not yet. KidSprint is still in development, so there is no signup and no waitlist. When it is ready, this site will say so.
KidSprintWhat keeps KidSprint safe for kids?
Guardrails are built in from the start rather than bolted on later, and parents get useful insight into what their child is working on without having to read every conversation.
FoundryWhat is Foundry?
A crew of 169 specialist AI agents for a team, across 14 divisions. You brief them once on your mission, your tone and your people, then work with them in direct or group chat. Foundry is live now at foundryagents.ai.
FoundryHow is Foundry different from SoulPrint Passport?
Passport is built for one person moving between AI tools. Foundry is built for a team working alongside a set of agents. Both run on the same engine, so context does not have to be rebuilt for either.
FoundryHow do I get into Foundry?
Foundry is invite-only — signup needs an access code. You can request one, or try a Signal Audit, which includes a free 24-hour trial. Both are linked from the Foundry page on this site.
All productsDo I need all three?
No. They are built for different people and run independently — they simply share the same engine underneath.
All productsIs there a mobile app?
No, and there does not need to be. MCP covers mobile through the apps you already have installed.
Start here
Pick the product. The engine is already running.
All three run on the same platform, so none of them is a bet on the others.
