为什么需要它 · Why

用 Claude 聊产品思路、创业方向、个人决策时，对话结束后思路往往还是散的。CaptureMind 让 Claude 在对话结束后直接把想法、目标、卡点、行动项结构化到一张导图里——尤其是卡点（Blocker），会被高亮显示，帮你看清自己真正卡在哪。

When you finish a deep conversation with Claude about product ideas, business strategy, or personal decisions, your thoughts are often still scattered. CaptureMind lets Claude structure them into a visual mind map — highlighting Blockers so you can finally see where you're stuck.
