Drune lets users personalize AI across the tools they already use

Summary

Drune is a product for creating personal profiles that tell AI how a user thinks, works, decides, and communicates. The profile can include rules about tone, priorities, workflows, constraints, and when to ask a person for help. Drune says these instructions can be used across AI tools people already use, including ChatGPT, Claude, Cursor, VS Code, Claude Code, Grok, and other MCP applications. Its examples show the same approach applied to emails, studying, meal planning, exercise, and job searches, with responses shaped by user-specific requirements such as a writing style, a budget, an injury, or a salary floor. Users create a Drune by uploading documents, links, code, or recordings, answering questions, reviewing what the system learned, and testing the results before connecting it to other tools. The product distinguishes personal judgment from ordinary document retrieval by representing what users know, how they work, what they believe, and where they draw a line. Users can keep a Drune private, share it with a team, or let others license the expertise without exposing the underlying files, notes, or Drune details. The page says the introductory free plan includes up to three Drunes, although that limit may later decrease; Drune Plus costs $2.99 per month, and private organizational installations require a separate request.
