Master
anything faster.
The voice-first thinking partner for people who go deep.
Why it matters
The more you understand, the more AI gives you back.
This isn’t about competing with AI — it’s about getting more out of it. The clearer you understand a problem, the sharper you can direct the tools that execute it: you think straight, you carry fewer unknowns, and you know exactly which unknowns are worth an experiment. Delegating execution pays off in proportion to how well you grasp what you’re delegating. Kustom is where you build that understanding — so everything you point at the work returns more, and the depth you keep building is what keeps you in demand.
What it does
A thinking partner, not a prompt box.
Voice keeps the effort low; the screen keeps it precise. You go deeper than you would alone — and the understanding is yours to keep.
Talk it through.
A real spoken conversation, not a prompt box. Think out loud, bring half-formed questions, follow a tangent. Interrupt it when it’s off track and it stops and listens. Speech runs on Kustom’s own infrastructure, so it stays low-latency and your words don’t go to an outside AI vendor.
See it take shape.
The point isn’t just to hear an answer — it’s to grasp it. As you talk, the structure of the topic appears on screen as readable cards, formatted text, and reports. Voice does the low-effort part; the screen does the precise part.
Go as deep as the topic demands.
When you need to master something, Kustom reads the live web for you — searching real sources, reading the pages, and pulling back a cited briefing you can interrogate further. You’re building a mental model, not collecting links.
Your understanding compounds.
Every conversation is saved, searchable, and titled automatically. Pick a thread back up a week later and continue building on it instead of starting cold.
Private by design.
Kustom runs its own AI models on its own infrastructure, in the EU. Your questions and your research aren’t sent to an outside model provider or used to train one.
Runs where you work.
iPhone, iPad, and Mac today — sign in with Apple or Google and continue on any of them. More Apple platforms are in progress.
Who it’s for
Built for people whose work is thinking.
The people who constantly have to master a new, complex topic before they can do their best work.
Consultants & advisors
Build genuine command of a new domain fast, between billable hours, so you speak about it with real understanding.
Founders & executives
Get to the bottom of a decision yourself, with sources, instead of waiting on someone to brief you.
Researchers & analysts
Go deep on a question and keep the thread, instead of losing your understanding across twenty tabs.
“The most dangerous way to use AI is to turn your brain off. Kustom keeps it on — and the deeper you understand, the more you get out of every model, agent, and tool you point at the work.”
FAQ
The short, honest version.
How is this different from a chatbot?
A chatbot answers and moves on. Kustom is built for understanding: you talk a topic through by voice while its structure builds up on screen, so you leave with a mental model instead of a transcript.
Is my data used to train AI models?
No. Kustom runs its own models on its own EU infrastructure. Your conversations and research aren’t sent to an outside model provider and aren’t used for training.
What devices does it run on?
iPhone, iPad, and Mac. Sign in once and continue on any of them. More platforms are coming.
What languages does it work in?
English and French today.
Can it actually do research, or is it just talk?
Real research. It searches the live web, reads the pages, and returns a cited briefing — not a summary of what a model happened to remember.
