Show HN: Drune – Personalize your AI and use it anywhere

Drune launched a personalization layer that teaches AI assistants a user's rules, style and decision-making, and works inside ChatGPT, Claude, Cursor, VS Code, Claude Code, Grok and any MCP app. The free plan includes three Drunes for a limited time, and Drune Plus costs $2.99 a month for additional profiles; the company says shared Drunes give others advice without exposing the owner's files or notes.

Your AI should know you, not just your files. Uploading documents gives an AI your facts. A Drune also teaches it your judgment: what you care about, how you decide, and what you would never do. So it makes the calls you would make. What you know Pulled from your documents, notes, code, and talks. How you work Your steps, in the order you take them. What you believe The rules you stick to, and why they matter. Your style Your favorite tools, defaults, and tone. How you decide When this happens, you choose that, for this reason. Where you draw the line What you would never recommend, and when to ask a person. Ready in four steps 01 Teach it Upload documents, links, code, or recordings, and answer a few quick questions. 02 Review it See what Drune learned about you. Keep what is right and fix what is not. 03 Test it Ask the same question with and without your Drune. Correct it until it sounds like you. 04 Use it anywhere Connect once, then use it in ChatGPT, Claude, Cursor, and more. A Drune for every part of your life Make one for money, one for travel, one for writing, and one for code. Each stays focused, so each gives sharper answers. Share it, or earn from it Keep a Drune to yourself, share it with your team, or let others license it. They get your expertise, never your files or notes. Questions - What is a Drune? - A Drune is a personal profile of how you think and work. Your AI reads it before it answers, so its answers follow your rules instead of generic advice. - Do I have to switch AI apps? - No. Drune works inside the AI tools you already use, like ChatGPT, Claude, Cursor, and VS Code. - Can other people see my files? - No. People you share with get advice for their task. They never see your documents, notes, or the details of your Drune. - What does it cost? - The free plan includes three Drunes as an introductory offer. That number will come down later. Drune Plus lets you create more for $2.99 a month. A private installation for an organization is a separate request. Need a private installation for your organization?
