记住 · Projects 钉的，Memory 学的Remember · What Projects Pin, What Memory Learns.
每开一个新对话，你都把同一段背景再贴一遍。Claude 用两种方式替你记住：一种你亲手钉（Projects 的知识库加自定义指令），一种它自己从对话里学（Memory，截至 2026-07 连 Free 都有）。这章讲两者怎么分工，以及什么时候该用隐身对话把记忆关掉。Every new chat, you paste the same background again. Claude remembers it two ways: one you pin by hand (a Project's knowledge base plus custom instructions), one it learns on its own from your chats (Memory, on every tier as of 2026-07). This chapter covers how the two split the work — and when to switch it off with an Incognito chat.
每开一个新对话，你都把同一段背景再贴一遍 —— 我是谁、这个项目怎么回事、希望你用什么口吻。Claude 其实在用两种方式替你记住这些：一种你亲手钉住，一种它自己学。Every new chat, you paste the same background again — who I am, what this project is, the tone I want. Claude already remembers all this two ways: one you pin by hand, one it learns on its own.一种是 Projects：你把固定的文件和一段指令钉在一个工作区里。另一种是 Memory：它从你历次对话里归纳你的偏好和习惯。这章讲这两者的分工，和它们各自的边界 —— 包括什么时候该把记忆关掉。One is Projects: you pin a fixed set of files and an instruction into a workspace. The other is Memory: it distills your preferences and habits from past chats. This chapter covers how the two divide the work, and where each one's edge is — including when to switch memory off.在分头讲之前，先认一下 Claude 替你记东西的几层 —— 普通对话是默认那层，聊完就散；真正会留下来的是下面这几样，各管各的事，别混着用：Before splitting them apart, name the layers Claude remembers you on — a plain chat is the default and disperses when you're done; what actually persists are the few below, each minding its own job, and they shouldn't be mixed:

Project 钉的是约定A Project Pins Conventions.
Project 钉的是你不想再说第二遍的话。A Project pins what you don't want to say twice.一个 Project 把两样东西钉在一个工作区里：一组固定文件（知识库），和一段自定义指令（口吻、角色、规则），作用于该项目内的每一次对话。1注 1Note 1Claude 帮助中心 · 什么是 Projects —— 把文档、代码、文字上传到项目知识库，并写一段项目指令，作用于该项目内的所有对话。Claude Help Center · What are projects — upload docs, code, and text to a project's knowledge base and write project instructions that apply to every chat inside it.每个项目带 200K 上下文，约一本 500 页的书；付费档在知识接近上限时自动转成检索（RAG），把可用容量扩到约 10 倍。2注 2Note 2Claude 帮助中心 · 创建与管理 Projects —— 每个项目带 200K 上下文（约一本 500 页的书）；付费档在知识接近上限时自动启用检索（RAG），把容量扩到约 10 倍。Claude Help Center · Create and manage projects — each project carries a 200K window (about a 500-page book); on paid plans it switches to retrieval (RAG) as knowledge nears the limit, expanding capacity ~10x.A Project pins two things into one workspace: a fixed set of files (the knowledge base) and a custom instruction (tone, role, rules) that applies to every chat inside it.1注 1Note 1Claude 帮助中心 · 什么是 Projects —— 把文档、代码、文字上传到项目知识库，并写一段项目指令，作用于该项目内的所有对话。Claude Help Center · What are projects — upload docs, code, and text to a project's knowledge base and write project instructions that apply to every chat inside it. Each project carries a 200K window, roughly a 500-page book; on paid plans it shifts to retrieval (RAG) as knowledge nears the limit, expanding usable capacity ~10x.2注 2Note 2Claude 帮助中心 · 创建与管理 Projects —— 每个项目带 200K 上下文（约一本 500 页的书）；付费档在知识接近上限时自动启用检索（RAG），把容量扩到约 10 倍。Claude Help Center · Create and manage projects — each project carries a 200K window (about a 500-page book); on paid plans it switches to retrieval (RAG) as knowledge nears the limit, expanding capacity ~10x.什么该进知识库？反复要引用、且大半年不变的东西：你的写作风格样本、团队术语表、某个长期客户的背景、一份你天天对照的规范。什么不该进：一次性的探索、还没定型的草稿、隔周就过期的数据 —— 这些塞进去，只会让检索时多翻几页噪音。What belongs in the knowledge base? Things you cite repeatedly and that hold for half a year: samples of your writing voice, a team glossary, a long-term client's background, a spec you check against daily. What doesn't: one-off exploration, drafts not yet settled, data that expires in a fortnight — put those in and you only add noise for retrieval to wade through.边界在「这个对话还属不属于这件长期的事」。属于，就在 Project 里开，让它继承知识库和指令；不属于，开个普通对话，别把临时的东西倒进这个工作区 —— Project 放错了会越用越钝。The line is whether this chat still belongs to that long-term thing. If it does, open it inside the Project so it inherits the knowledge base and instruction; if it doesn't, use a plain chat and don't pour throwaway material into the workspace — a Project filled wrong gets duller the more you use it.

Memory 学的是习惯Memory Learns Your Habits.
Memory 不用你钉，它从对话里自己学。Memory isn't pinned — it learns from your chats.Project 要你主动放文件、写指令；Memory 不用。它默认开着，覆盖所有档位，连 Free 都有；4注 4Note 4Anthropic · Claude 套餐与价格 —— 记忆（memory）列在 Free 档功能内，即对所有档位开放。截至 2026-07。Anthropic · Claude Plans & Pricing — memory is listed under the Free tier, i.e. available on every plan. As of 2026-07.每 24 小时把你的对话归纳一次，记的是职业层面的东西：你的角色、在做的项目、沟通风格、技术偏好。而且按项目分隔 —— 每个 Project 有自己独立的记忆空间，不和别的项目或普通对话混。3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory.

It's on by default, on every plan, Free included;4注 4Note 4Anthropic · Claude 套餐与价格 —— 记忆（memory）列在 Free 档功能内，即对所有档位开放。截至 2026-07。Anthropic · Claude Plans & Pricing — memory is listed under the Free tier, i.e. available on every plan. As of 2026-07. every 24 hours it synthesizes your conversations, capturing the professional layer: your role, the projects you're on, your communication style, your technical preferences. And it's partitioned by project — each one has its own memory space that doesn't mix with other projects or ordinary chats.3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory. As of 2026-07.它不是黑箱。去「设置 > Capabilities」点开查看与编辑记忆，你能读到它归纳出的那段话，错的当场改；也能在对话里直接说「记住我以后都要 X」。3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory. As of 2026-07.这点比你想的重要：它替你记住的东西，会悄悄影响之后每一次回答。It isn't a black box. Under Settings > Capabilities you can open and edit the memory, read the summary it has formed about you, and fix what's wrong on the spot; you can also just tell it in a chat, 'remember that from now on I want X.'3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory. As of 2026-07. This matters more than it sounds: what it remembers quietly shapes every answer that follows.边界：值得让它记的，是稳定的偏好 —— 你要的格式、语气、长期约束；不值得的，是会变的状态 —— 你这周在忙的临时项目，记下来下个月反而误导它。Memory 记的该是习惯，不是近况。它最隐蔽的成本不是记错，是它还记着三个月前的你，而你已经变了 —— 所以隔段时间该去翻一翻、删一删。The line: what's worth remembering is stable preference — the format you want, the tone, long-term constraints; what isn't is changing state — the temporary project you're busy with this week, which next month only misleads it. Memory should hold habits, not your latest status. Its most hidden cost isn't getting you wrong — it's still remembering the you of three months ago, after you've changed; so it's worth reopening and pruning every so often.
提示词Prompt教 Memory 记什么、忘什么Teach Memory what to keep
记住这些（稳定的偏好）：<我的角色 / 长期约束 / 固定的格式与语气>。
别记这些（会变的近况）：<这周的临时项目 / 一次性的数字 / 还没定的探索>。

记住这些：我是独立开发者，做 iOS 工具类 app；回答一律中文、先结论后细节；代码用 Swift，别用 force-unwrap。
别记这些：我这周在赶的「报税 app」是临时外包，下个月就结束，别当成我的长期方向。
这条只用这一次、别写进记忆：这是某客户的真实姓名和合同金额。
（想确认它记了什么，去「设置 > Capabilities」翻记忆摘要，错的当场改。）Remember these: I'm a solo developer building iOS utility apps; answer in Chinese, conclusion before detail; code in Swift, no force-unwraps.
Don't remember these: the 'tax-filing app' I'm rushing this week is temporary contract work that ends next month — don't treat it as my long-term direction.
Use this once, don't write it to memory: this is a client's real name and contract amount.
(To check what it kept, open the memory summary under Settings > Capabilities and fix what's wrong on the spot.)

什么时候关掉记忆When to Switch Memory Off.
记得太多，有时是负担。Remembering too much is sometimes a burden.你钉的（Project 指令）是显性约定，你说了算；它攒的（Memory）是隐性习惯，它替你归纳 —— 两者冲突时，以 Project 指令为准。但有些活你压根不想被它记：一次性的敏感数据、和日常无关的临时问题、还没定型怕被它学歪的探索。What you pin (a Project's instruction) is an explicit convention — you decide; what it accumulates (Memory) is an implicit habit — it infers; when the two conflict, the Project instruction wins. But some work you simply don't want it to remember: one-off sensitive data, a stray question unrelated to your routine, exploration that hasn't settled and you'd rather it not learn crooked.这时开一个隐身对话（Incognito，新开对话时选幽灵图标）—— 它是临时的，不写入记忆。3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory. As of 2026-07.想更彻底，可以在设置里暂停记忆（保留旧的、不再新增）或重置（清空重来）。关掉记忆不是退步，是把它的注意力还给真正该记的事。For those, open an Incognito chat (the ghost icon when you start a new one) — it's temporary and writes nothing to memory.3注 3Note 3Claude 帮助中心 · 用对话搜索与记忆延续上下文 —— 记忆默认开启、每 24 小时归纳一次、按项目分隔；在「设置 > Capabilities」查看与编辑，也能暂停或重置；隐身对话（Incognito）不写入记忆。截至 2026-07。Claude Help Center · Use chat search and memory to build on context — memory is on by default, synthesized every 24 hours, kept separate per project; view and edit it under Settings > Capabilities, where you can also pause or reset it; an Incognito chat writes nothing to memory. As of 2026-07. To go further, pause memory in Settings (keep the old, add no new) or reset it (wipe and start over). Switching it off isn't a step back — it returns its attention to what actually deserves remembering.和 Skills 的分工记一句就够：Project 钉上下文，Skill 钉方法 —— 一个管「这件事的背景」，一个管「这类事怎么做」。下一章就是 Skills。One line settles the division with Skills: Projects pin context, Skills pin method — one holds 'the background of this thing,' the other holds 'how this kind of thing is done.' The next chapter is Skills.把这章用到一件你这月重复做过的事上：Apply this to something you've repeated this month:
01
挑一件每次都重贴背景的事，建成 ProjectPick a re-paste task and build a Project
找一件你这月做过 3 次以上、每次开头都要交代同一段背景的活；建一个 Project，放进固定文件，写一段自定义指令把它钉住。Find a task you've done 3+ times this month where you re-explain the same background each time; build a Project, add the fixed files, and write a custom instruction to pin it.
02
聊几轮后，去设置里看 Memory 记了什么After a few chats, check what Memory captured
在这个 Project 里聊几轮，隔天再去「设置 > Capabilities」翻它的记忆摘要 —— 看它归纳得对不对，错的当场改掉。Chat a few rounds inside the Project, then the next day open its memory summary under Settings > Capabilities — check whether it got you right, and fix what's wrong on the spot.
03
拿一件一次性的事开隐身对话Take a one-off into an Incognito chat
挑一件你不想被记住的临时问题，用隐身对话问，确认它没进任何记忆。记下：哪些该钉、哪些该忘。Pick a one-off question you don't want remembered, ask it in an Incognito chat, and confirm it entered no memory. Note which to pin and which to forget.
你钉的是约定，
它攒的是习惯.
What you pin is conventions,
what it accumulates is habits.
