Strengthen everything, replace nothing.
An AI that belongs to you: thinks locally, remembers you, runs on hardware you already own.
A system qualifies as a PCE only if it meets all six:
The agent is yours; it exists without any vendor account
Core reasoning runs on the user's own device
It remembers you across days, months, years
Enforced by design, not by promise
Not locked to any vendor's ecosystem
No new phone required
A mirror does not speak over you.
It shows you to yourself, clearer.
镜子不会替你说话，
它只把你照得更清楚。
An exoskeleton has no heartbeat of its own.
It moves when you move —
and all its strength counts as yours.
外骨骼没有自己的心跳。
你动，它才动——
它的全部力气，都算你的。
Many are building a new center for the phone.
We looked, and saw the seat was never empty:
it has always been you.
许多人在为手机建造新的中心。
我们看了看，发现那个位置从来不曾空着——
一直坐在那里的，是你。
| An Agent OS | A PCE |
|---|---|
| Ships with a new phone | Runs on the phone you already own |
| Your assistant lives inside a vendor account | Your assistant exists without any account |
| Memory feeds the platform's user profile | Memory stays yours — stored locally, exportable anytime |
| Privacy is a clause in the terms | Privacy is a gate in the architecture |
| Locks into one ecosystem | Ecosystem-neutral — even other agents become resources it calls for you |
| Replaces your apps with its own flows | Strengthens everything, replaces nothing |
A promise can be broken. An architecture cannot.
承诺会被打破，架构不会。
Sovereignty and memory belong to the user.
主权与记忆，归于用户。

“Born only to carry you across into the AI era”（只为渡你入AI新时代）
Kawagebo is the sacred peak of the Meili range that no one may summit; we borrow the name in tribute.
The mountain is not there to be climbed. It is there to watch over the valley.
神山不供攀登，只作守望。
PCE——个人认知外骨骼（Personal Cognitive Exoskeleton）：一个属于你的AI。它在本地思考、长期记得你、隐私由架构保证而非承诺保证、跨生态中立、跑在你已经拥有的硬件上。
站位：我们不是操作系统，也不是又一个Agent平台。PCE不与OS争位、不与Agent争位、不与云争位——它只站在用户身边。你想用什么，它就替你去用。强化一切，取代无物。 判据只有一条：主权和记忆归用户。
①用户拥有 ②本地思考 ③长期记忆 ④架构级隐私 ⑤跨生态中立 ⑥跑在你已有的硬件上——不需要为AI换一台新手机。
参考实现镜-初将于2026年9月发布：可跑的、源码公开的教学级PCE（Android）。卡瓦格博是梅里雪山无人可登顶的神山，我们以此名致敬——一位守护者，只为渡你入AI新时代。
| Agent OS | PCE |
|---|---|
| 随新手机出厂 | 跑在你已有的手机上 |
| 助理住在厂商账号里 | 助理不依赖任何账号而存在 |
| 记忆喂给平台的用户画像 | 记忆归你：本地存放、随时导出 |
| 隐私是条款里的一句承诺 | 隐私是架构里的一道闸门 |
| 锁进一家生态 | 跨生态中立——连别家Agent都成为它替你调用的资源 |
| 用自己的流程取代你的App | 强化一切，取代无物 |
承诺会被打破，架构不会。
主权与记忆，归于用户。
