The problem
Every time you open a different AI tool, you start from scratch. Here's what a typical day looks like:
"I'm building a REST API for a climate analytics platform called Carbon Dashboard. The launch client is GreenTech Corp, going live in May..."
"I'm working on Carbon Dashboard at Reefline, it's middleware for environmental data. I need to build auth routes for enterprise SSO..."
"So I have this data pipeline for Carbon Dashboard, it uses priority-based scheduling with time windows..."
"I'm Head of Product at Reefline, building Carbon Dashboard. Can you help me draft a client update for GreenTech Corp..."
You spend 30–60 minutes a day re-explaining your context to AI tools. What if they already knew?
The solution
PROMPT
"Help me plan the API for my project"
"Sure! I'll need some context. What kind of project? What's your tech stack? What endpoints do you need? Who's the target audience?"
Generic. Asks 5 questions before doing anything.
Same prompt. Same developer. The only difference is Concentration.
How it works
Paste one URL into Claude, Cursor, ChatGPT — any tool that supports MCP. One URL works everywhere.
30 secondsYour AI asks a few friendly questions about your work, skills, and preferences. Two minutes, done.
2 minutesEvery AI tool now knows your context. Your profile grows automatically as you work. No maintenance, no thinking about it.
Works foreverCross-tool intelligence
Your work follows you across every tool. Nothing is lost. Nothing needs re-explaining.
"Design the REST API for Carbon Dashboard's data ingestion"
Cursor creates a detailed API design using your project context, tech stack, and team structure.
"Save this to my vault"
Document appears in your Concentration vault — searchable, structured, and accessible from any tool.
"Review my Carbon Dashboard API design from the vault"
Claude retrieves the document and reviews it with full context about your project, standards, and timeline.
What it learns
Concentration captures structured signals from your conversations — topics, skills, project references, preferences. Never your actual messages. Everything goes to your dashboard for you to approve or dismiss. Nothing changes without your say.

Questions
No. We capture structured signals — topics, skills, project references — never your actual messages. Think of it like a meeting summary: we note that you discussed React architecture, not what you said about it.
Yes, but ChatGPT works best when you mention Concentration in your prompt. Claude and Cursor provide a more automatic experience. We recommend starting with Claude for the best first experience.
Cursor works great with the @concentration tag. Your profile, vault, and learning all sync across Cursor and your other tools.
Claude's memory only works in Claude. Concentration works across every AI tool you connect. Design an API in Cursor, review it in Claude, draft a client update in ChatGPT — they all share the same context about you and your work.
It's gone. Permanently. Not archived, not retained for 30 days, not backed up somewhere hidden. We run a real delete — every row, every file, every signal.
No. Not ours, not OpenAI's, not Anthropic's. Your data exists solely to personalise your own experience.
No. No browser extension, no desktop app. You paste one URL into your AI tool's settings. That's the entire setup.
Your AI tools should know you by now. Two minutes to set up, works across every tool, grows automatically.
