Give your AI an operating system. Persistent context that compounds session over session.
$ curl -sSL contextium.ai/install | bash A genuine multiplier across everything you do. But every session starts from zero. You re-explain who you are, what you're working on, what you already decided. The gap between AI's promise and your reality never closes.
A flat list of facts in a black box. No structure. No rules. No routing. No compounding. Your AI has the same IQ on day 1,000 as day 1.
A sticky note.
A structured operating system with persistent context, behavioral rules, multi-agent delegation, and session compounding. Every session builds on the last.
An operating system.
Your goals. Your relationships. Your communication style. Your decision history. Your health data. Your business metrics.
It's not a generic assistant anymore — it's your assistant. The experience deepens every single day.
Every other AI tool locks your context inside their platform. If they shut down, raise prices, or pivot — months of accumulated intelligence vanishes.
With Contextium, you own everything. Plain markdown in a git repo. Switch providers anytime. Your context comes with you.
Companies have wikis, CRMs, and project management tools. Individuals have nothing.
Your career knowledge, health decisions, financial strategy, relationship context — it all lives in your head or scattered across 20 apps. Contextium gives you what organizations have had for decades.
Why burn expensive tokens on web research? Route it to Gemini. Bulk file edits? Codex. Browser automation? Playwright.
Your primary AI stays focused on strategy and decisions. You get more leverage for less money. The system optimizes your AI spend automatically.
Six months from now, you can git log any decision and see exactly what you chose, what you rejected, and why.
No more "why did I do it that way?" No more re-exploring dead ends. Your journal entries capture the reasoning. Git preserves it forever.
Most AI "frameworks" are just prompts. Contextium has actual enforcement — git hooks that catch drift before it happens.
Delegation thresholds. Context efficiency limits. Session discipline. Credential handling. Not documentation — infrastructure.
Your AI knows your name and what you do.
It knows your goals, your team, your decisions, your patterns.
It's the most informed collaborator you've ever had.
Journal entries capture decisions. Knowledge domains accumulate reference data. People cards deepen. Projects build history. The compounding never stops.
The installer handles everything — your name, your AI agent, your integrations. Five minutes from now, your AI has an operating system.
$ curl -sSL contextium.ai/install | bash Your name, which AI agent you use, which services to connect. It sets up your personalized repo and installs the CLI.
The installer launches your AI agent inside your new Contextium. It already knows your name and has the right instruction file configured.
Every session from now on builds on the last. Decisions persist. Context accumulates. Day 30 is dramatically more powerful than day 1.
A structured git repo with six layers that your AI navigates automatically.
The brain. Lazy-loads only the files relevant to the current session. No token bloat, no preloading.
Goals, health tracking, news digest, daily briefing, error remediation, shared utilities. Add your own.
Google Workspace, Todoist, Home Assistant, QuickBooks, Windmill, and 22 more. Configure only what you need.
People cards, health data, goals, finance — domain-organized reference data that grows richer over time.
Behavioral rules, delegation policies, session discipline. Not just documented — actually enforced via hooks.
Every session ends with a structured log. Next session, your AI knows what you decided and why. No repetition.
Contextium is Apache 2.0 licensed. No premium tier. No hosted service. No data collection. Just a git repo of markdown files that you own completely.
This isn't a weekend project. Contextium was refined through months of daily production use before being open-sourced.
One command. Five minutes. Then every session compounds.
