Contextium gives your team a shared AI context library. Your standards, decisions, and docs load automatically into Claude, Cursor, and ChatGPT — in every conversation, for every teammate, forever.

Without shared AI context, teams waste hours every week on repetitive prompting
Every new conversation starts from zero. Your brand voice, code standards, and architecture decisions vanish the moment you close a chat. Teams re-explain the same context dozens of times a day across dozens of conversations.
One developer writes a perfect context prompt. Their colleague writes something different. A third person forgets entirely. The result: wildly inconsistent AI outputs from the same underlying tool — all from the same team.
Your best AI prompts and context documents are scattered across notes apps, Slack messages, and personal system prompts. When that person is on holiday — or leaves — the knowledge disappears with them.
You need Claude to know X, Cursor to know Y, ChatGPT to know Z. Managing separate context for five AI tools across ten teammates is a full-time job — or a guarantee that it just doesn't happen.
One shared library. Every AI tool. Zero manual prompting.
Write your team's knowledge once — coding standards, brand guidelines, architecture decisions, SOPs, playbooks. Organise with tags and projects. Contextium auto-saves every 10 seconds with full version history.
Run one command and your entire AI context library is live inside every AI tool your team uses. No configuration files to maintain. No per-tool setup.
From the first message of every session, your AI assistant searches your Contextium library and loads the relevant docs. Your team members get consistent, high-quality responses because they're all drawing from the same source of truth.
Any knowledge your AI tools should always know
Naming conventions, error handling patterns, API response formats, testing requirements
Why you chose your stack, database patterns, microservices boundaries, security policies
Writing style, messaging guidelines, product terminology, approved language
Feature specs, user personas, roadmap context, competitive positioning
Incident response, onboarding checklists, deployment procedures, runbooks
Git workflow, PR process, meeting templates, communication patterns
Industry-standard Model Context Protocol delivers your docs into Claude, Cursor, and other AI tools automatically.
One library, every teammate. Everyone's AI assistant draws from the same context — consistent responses guaranteed.
Edit a doc and it's live everywhere immediately. No cache to clear, no teammates to notify.
Every change tracked with visual diffs. Roll back any doc to any previous version in one click.
Semantic search finds the right context docs for each query, not just keyword matches.
One context library connects to Claude, Cursor, VS Code, Windsurf, ChatGPT, and any MCP-compatible assistant.
AI context management is the practice of storing, organising, and automatically delivering the background information your AI tools need to give accurate, consistent responses. Instead of copy-pasting context into every conversation, Contextium connects your documentation directly to AI assistants via MCP.
Without shared AI context, every teammate prompts their AI differently and gets inconsistent results. Shared AI context means everyone draws from the same knowledge library, producing consistent, high-quality outputs across the whole team.
Contextium uses MCP (Model Context Protocol) — an open standard supported by Claude, Cursor, and other AI assistants. Once set up, your AI tool automatically searches your Contextium library and loads relevant docs into every conversation.
Yes. Because your context lives in Contextium rather than in a chat window, it persists forever. Every new conversation has access to your full library. When you update a doc, the change is live for every teammate's AI session instantly.
Contextium works with Claude Desktop, Claude Code, Cursor, VS Code (via MCP extension), Windsurf, and any assistant that supports MCP. Remote MCP is available for tools that support SSE connections.
System prompts are per-tool, per-user, and easy to forget. Contextium's context library is centralised, version-controlled, and shared across your whole team. Update it once and every teammate's AI sessions get the new context automatically.
