BYOI: bring your own intelligence.

Your editor has an AI. Ours doesn't. The one you already pay for does the work.

Every AI app builder is in the token-resale business.

Lovable, Bolt, Replit, Softgen. They buy tokens from Anthropic and OpenAI, mark them up, and sell them back to you as credits. You pay your AI subscription. Then you pay theirs.

That's not a product. That's a middleman.

"Bring your own" is how tech got flexibility.

Your key. Your device. Your drinks. The pattern is thirty years old. We just extended it to the thing that matters most now.

How it works.

Mistflow is an MCP server that runs inside the chat app you already use: Claude Desktop, ChatGPT, Cursor, Codex. When you describe what to build, your subscription's AI does the reasoning. Mistflow supplies the tools: plan the app, write the files, deploy to a real URL.

We never touch a token. The code lives on your machine. The infrastructure lives on ours. Clean layers.

What falls out of the architecture.

• Flat price. $19 per app, per month. We charge for infrastructure because that's all we provide. No credits, no top-ups, no meter.
• Any model. Claude Sonnet, GPT-5, whatever ships next week. When your editor's AI gets smarter, Mistflow gets smarter for free.
• Your code, your exit. Standard Next.js, Postgres, Better Auth. Runs on Vercel, Fly, your own box, your laptop. There is no Mistflow runtime to migrate off.

Why this is the future.

AI subscriptions are consolidating. A year from now, almost everyone who builds software will already pay for Claude or ChatGPT. Builders that charge a second time for the same tokens, with margin on top, will look like long-distance phone companies.

The clean layer is: intelligence on your subscription, tools on ours. One price, one exit, one stack.
