I built an MCP memory that never turns a project into one summary

I kept losing small but important project details after long AI chats got summarized, so I built SkyOS. It keeps a project as separate, dated notes for facts and decisions. A pricing decision, deadline, or change of mind stays visible as its own note instead of being folded into one growing project summary. You can use projects' memory in a new chats like "continue <memory>", for example: continue Northwind pricing and pick that project back up from its saved notes. I built it as

AI 分析

痛点：长时间 AI 对话被自动总结后，项目里的关键小细节（定价决策、截止日期、需求变更）被折叠进一段摘要里永久丢失，新开对话无法续接。

目标用户：用 Claude/ChatGPT/Codex 长期推进同一项目的开发者、独立开发者、小型产品团队，以及同时维护多个项目的人。

证据：I kept losing small but important project details after long AI chats got summarized, so I built SkyOS. / A pricing decision, deadline, or change of mind stays visible as its own note instead of being folded into one growing project summary. / It is free to try during the beta / what would you need to see before trusting one with a long-running project?

变现：订阅制 SaaS：免费档限制项目数与记忆条数，付费档按 $8–15/月提供无限项目、跨设备同步、团队共享记忆与导出；后续可按 API 调用量计费或卖团队版席位。

MVP：两周内可做：远程 MCP server（封装 tools：add_note / list_notes / continue_project）+ SQLite 存结构化笔记（时间戳、类型标签：事实/决策/变更/承诺）+ 关键词与 embedding 混合检索，按项目名召回最近 N 条相关笔记注入上下文；再加一个极简 Web 页用于浏览与删除记忆。差异化点是“绝不总结、逐条保留 + 时间线视图 + 变更对照（同一决策的版本历史）”。

竞品：Mem0、basic-memory、Cline Memory Bank、官方 MCP memory server、Letta (MemGPT)、Zep

摘要：开发者因长 AI 对话被总结后丢失项目细节，自建 SkyOS：一个远程 MCP 服务器，把项目记忆拆成带日期的独立笔记（事实/决策/变更），支持用 "continue Northwind pricing" 在新对话中续接，兼容 Codex、ChatGPT、Claude。目前 beta 完全免费，帖子只征集反馈，没有任何付费、用户量或收入数据；MCP 记忆类竞品已相当密集。
