Stop managing prompts in personal notes, Slack threads, and scattered text files. Contextium gives your team a shared, versioned AI prompt and skills library — live in Claude, Cursor, and ChatGPT automatically via MCP.

The best prompts in your team live in DMs, channels, and threads. They're impossible to find, impossible to update, and invisible to anyone who wasn't in the original conversation.
Each developer maintains their own collection of Cursor rules, Claude instructions, and ChatGPT system prompts. No consistency. No sharing. When they leave, the prompts go with them.
.cursorrules files live in individual projects but rarely get standardised across the team. One repo has great AI context. The next has nothing. Results vary wildly.
You improved a prompt last month. Now it's worse. What changed? No idea — there's no history. You're rewriting from memory, losing the iteration work your team has already done.
In Contextium, skills are named, versioned AI instruction documents — connected to your tools via MCP
Write system prompts, Cursor rules, brand guidelines, code review checklists, content templates, or any reusable AI instruction. Name and tag them for easy discovery.
Add teammates to your workspace. Every skill you create is instantly available to their AI tools. No sharing links. No copy-pasting. The library is the single source of truth.
Connect your AI tools once. From then on, skills load automatically into every conversation — no prompting, no copy-pasting, no forgetting.
