AgentTune generates personality-based tuning files for AI assistants like Claude, ChatGPT, Cursor, and Gemini. You complete a short personality assessment, and the tool outputs a ready-to-paste Markdown prompt file calibrated to your psychological profile. It draws on five frameworks — MBTI, Big Five, Enneagram, DISC, and Attachment Theory — covering 43 distinct tuning configurations. The free tier gives you framework-specific files; a one-time $9 upgrade produces a synthesized master file that reconciles conflicts across all five systems (for instance, when your MBTI and Big Five results point in different directions). Useful for anyone who finds generic AI responses feel off or impersonal — developers, writers, researchers, or power users who want their assistant to communicate in a style that actually fits them. All tuning files are MIT-licensed.
