What problem does it solve?

brother.skill turns scattered memories, clips, screenshots, and chat logs into a reusable assistant that speaks in your bro’s voice, humor style, catchphrases, and group vibe.

Core Features & Use Cases

  • Bro distillation from real sources: Feed it YouTube/TikTok/Twitch/Twitter/Discord/WeChat/group-chat exports or your own description to capture how the bro talks and what makes them funny.
  • Voice, comedy, energy, content personality, and relationship modeling: Builds a structured profile across the bro’s speaking patterns, humor style, energy triggers, online content traits, and your inside-joke context.
  • Bro interaction & group-chat simulation prompts: Generates prompts that keep the bro in character, match energy levels, and simulate how multiple bros would interact.
  • Self-learning profiles with local persistence: Appends new inputs to a living profile and logs interactions locally so accuracy improves over time.

Quick Start

Tell the skill to distill your bro from a group chat export by providing the exported file path and the bro’s name, then use the resulting profile to ask questions in their voice.
