AI forgets you.
Your hardest problems can't afford that.
MindrianOS is the thinking partner that remembers every decision you made, pushes back when your reasoning has gaps, and reaches back into your own evidence the moment it matters again. You talk. It builds the room. Every session is sharper than the last.
Built for hard problems that span weeks and cross domains, not single answers.
Free plugin. Requires a paid Claude plan (Claude Pro, $20/mo, or higher). See pricing.
The grid is your room. The line is what it remembers.
Install in three steps.
No terminal experience needed. The full guide walks you through every screen.

Larry wakes up and the Data Room starts taking shape underneath the conversation.
Connect the Brain

Your venture is a wicked problem. Every other tool was built for a tame one.
Notion, Jira, a folder of docs: they assume the problem holds still while you work on it, and they treat every file as an island. A real venture is none of that. A change in one corner quietly breaks an assumption in three others. MindrianOS is built for that shape on purpose, which is why it keeps the whole body of work connected instead of filed away.Read the long version.
Watch it reach back.
Two sessions, days apart. You never re-explain a thing. The decision you made on Monday is the decision Larry brings back on Thursday, unprompted, because the new problem touches the old one. That is the whole product.
every decision, still connected
Find the problem. Show what you missed. Defend what you decided.
Find the problem.
Not 'solve my problem', but 'help me figure out which problem is worth solving'.
Show what you missed.
Cross-domain connections and directions that emerge from your accumulated evidence.
Build what you couldn't alone.
Analysis, strategy, and deliverables at a depth that would otherwise eat weeks.
Defend what you decided.
Every claim traces to evidence. When someone asks why, the answer is in the room.
One graph teaches. One graph remembers you.
Think of a teacher and your notebook. The teacher knows the method and writes into your notebook. The notebook is yours and never leaves your desk. A pattern you wrote in one project can light up in another, without your files ever changing hands. That cross-room reach is the part nobody can copy, because it is built from decades of real teaching.
How the Brain worksNot intuition. Backed by research.
People who connect information across domains beat deep specialists, even specialists with better access. The edge is not knowing more, it is connecting more. MindrianOS makes those cross-domain connections on purpose.
When researchers compared thinking harder against finding better information, better retrieval won by a wide margin. Reach beats raw horsepower. The persistent room and its graph exist for exactly that reason.
And in studies of people alone, AI alone, and people-plus-AI, the AI alone converged fast and its ideas went stale, while the human-AI pair kept exploring. That is why this gets better with sustained use instead of flattening out.
Anyone working a hard problem across time.
Researchers
Arrive with a hypothesis, use it to validate and stress-test toward rigorous analysis.
Founders
Arrive with a direction but no destination, use it to find the real problem and build.
Innovation courses
Students explore unfamiliar domains and build opportunity portfolios across a term.
Tech transfer
Triage large portfolios of disclosures, frame problems, and test commercial viability fast.
Deep-tech ventures
Competitive positioning and strategic paths, with claims checked against the record.
Creative and corporate
Product lines, curricula, procurement, and regulatory work that span many sessions.
Who built this.
Lawrence Aronhime
Creator of the PWS (Problems Worth Solving) methodology. 20+ years developing it through direct application with students, startups, corporations, and government: the codified, tested practice MindrianOS runs on.
Jonathan Sagir
Co-founder and builder. Architected MindrianOS: the persistent Data Room, the methodology engine, the knowledge graph, the proactive intelligence layer, and the deployment infrastructure.
A few minutes, and one honest heads-up.
Claude Code asks you to approve each step the first time it runs. Ten or more prompts is normal, not a problem. Pick “always allow” on the ones you are happy with and you will not see them again. Theinstall guidewalks you through every screen, built for people who have never opened a terminal.
