AI 分析
痛点：求职者和职场人在面试、会议、电话中需要实时、隐蔽的AI辅助，以便在对方察觉不到的情况下快速获得回答提示。
目标用户：求职者、销售、咨询顾问、需要频繁参加英文会议或高压面试的人
证据：Marrow is an AI that hides on your screen during interviews, meetings and calls, listens in real time and has answers ready before you even ask. Nobody in the room sees anything. ... they'd shown it to someone they knew who was struggling to break into an industry ... Last week they sent someone my way directly.
变现：订阅制SaaS，按周/月收费；可分层：基础实时转写+提示、高级行业题库+个性化回答、团队版会议辅助。
MVP：2周内用桌面悬浮窗或浏览器扩展做MVP：系统音频采集+Whisper实时转写+LLM生成简短回答，支持热键隐藏、透明背景、低延迟输出；先用自带API key的本地模式规避成本。
竞品：Final Round AI、Interview Copilot、Cluely、Otter.ai、Poised
摘要：原帖分享Marrow构建8个月后，最初最强烈反对的人反而主动推荐了用户。Marrow是在面试、会议和通话中隐藏于屏幕的实时AI，能旁听并提前给出答案。帖子没有披露收入或定价，需求验证仅为单次推荐，且该赛道竞品已较多。
