The problem

You use five AI tools and explain yourself in all of them.

You use 5 AI tools a day and explain yourself in all of them.

Claude for strategy, ChatGPT for content, Perplexity for research, Cursor for code, Midjourney for graphics. Three different strangers. You re-explain your product, your target audience, your positioning to each one. Context burns. Time burns. Energy burns.

Good decisions get made and then forgotten.

You decided on your positioning three months ago. You decided not to pivot. You decided which market to focus on. But you switched tools or closed the tab and the decision disappeared. You find yourself re-arguing the same decision with Claude again.

Your AI outputs sound generic because the AI doesn't know your voice.

Every piece of content needs heavy editing because Claude doesn't know your brand. The copy sounds like it was written by a bot. Your email sounds like everyone else's email. You spend more time editing than creating.

The solution

One /ctx URL works in every tool you use.

One /ctx URL works in every tool you use—paste or MCP.

Save your business context once. Paste your /ctx URL in Claude, ChatGPT, Cursor, Perplexity. Or connect it as an MCP server. Every AI tool knows your product, your positioning, your decisions before you start.

PROJECTS layer saves decisions with dates—never decide the same thing twice.

You decided to focus on product-market fit before growth. You decided on a pricing model. You decided against pivoting. These decisions stick. Claude sees what you've chosen and why. No wasted context re-arguing old decisions.

SELF layer holds your voice, tone, and brand constraints—outputs sound like you.

Save your brand voice once: your tone, your vocabulary, what you never say, your communication style. Every AI tool uses the same voice. Content from Claude, ChatGPT, and Perplexity all sound like your brand.
