PalmVellum is an open-source platform that gives the native apps on a 1996–2003 Palm Pilot AI-assist and cloud sync — while leaving the Palm itself completely alone.

You write on the Palm because it's quiet. Two AAA batteries. 160×160 monochrome screen. No always-on radio. No camera. No infinite scroll. You hold it, you note things down, you put it away. The platform watches the cloud copy and helps when called.

Not low quality. Not retro for retro's sake. Low-fi = low fidelity, deliberately. Fewer pixels, fewer notifications, fewer pretexts to pick up the device. The platform brings AI and cloud in where they're genuinely useful — natural-language input parsing, transcription of handwritten sketches, daily research digests, agentic event / task creation — and stops there. We don't profile you. We don't show ads. We don't notify because someone you don't know looked at your profile. There is no profile.

Both sides — Palm and platform — share one dataset per user. Multiple Palms in the same household read and write the same set of records.

Help you accumulate a slow, deliberate body of personal records — calendar, contacts, notes, sketches, research digests, expenses — without being interrupted by your own tools. The Palm holds them in cold storage on AAA batteries. The platform holds the duplicate cloud copy and runs the AI assist whenever called.

• Apache 2.0. Code on this GitHub.
• BYOK (Bring Your Own Key) for AI providers — OpenAI, Anthropic, or Google Gemini. Your usage is your own bill. A platform-credits option (via Airwallex) is opt-in.
• No social, no analytics, no email marketing. You write the records, you own them.
• AAA-battery Palms (1996–2003) are our reference target and design focus. That's the device we believe in and test on. The platform itself just speaks HotSync, so other Palm OS devices outside our target are welcome to use it too; we just won't be testing those.
• The Palm stays Palm. We will never push a custom firmware. The platform speaks the existing HotSync protocol to the existing PalmOS apps. If a conduit doesn't work on your model we fix the conduit — the model itself never changes.

A native Android companion called Palm Organizers is in preparation under packages/android/ — wrapping the SvelteKit Organizers shell via Capacitor so the same UI runs on phones for users who want the AI assist without sitting at a desk. Status: scaffold only.

PalmVellum 是一個開源平台，為 1996-2003 年那批 Palm Pilot 的原生 app 加入 AI 輔助同雲端同步 — Palm 機本身一點都唔需要改。

你揀 Palm 是因為佢靜。兩粒 AAA 電池。160×160 黑白屏。冇恆常通訊。冇鏡頭。冇無限滾動。攞上手寫嘢，寫完放低。平台就喺後台守住雲端副本，要用 AI 嗰陣先攞出嚟。

唔係指品質低。唔係懷舊 for 懷舊。Low-fi = 低保真，有意嘅。 像素少啲、通知少啲、令你拎機嘅藉口少啲。平台只係喺 AI 同雲端真係有用嘅地方介入 — 自然語言輸入解析、手稿辨識、每日新聞摘要、自動執行任務／日程 — 然後止步。我哋唔追蹤你嘅閱讀習慣，唔賣廣告，唔會因為「有人睇過你嘅 profile」推 push notification 畀你。根本冇 profile。

兩邊（Palm 同平台）每個 user 共用一個資料集。同一個家庭幾部 Palm，讀寫同一組 records。

幫你慢慢累積一份有意識嘅個人紀錄 — 日程、聯絡人、記事、手稿、研究摘要、開支 — 又唔會俾自己嘅工具不斷打斷。Palm 機係 AAA 電池支撐嘅冷儲存，平台保存雲端副本同負責 AI 輔助。

• Apache 2.0，code 喺呢個 GitHub。
• BYOK（自帶 API key）AI 供應商 — OpenAI、Anthropic 或 Google Gemini。消費由你自己 control。平台 credits（Airwallex 付款）係 opt-in。
• 冇 social、冇 analytics、冇 email marketing。Records 由你寫，亦由你擁有。
• AAA 電池 Palm (1996-2003) 係我哋嘅參考目標同設計重點 — 嗰個係我哋相信、會親自測試嘅機型。但平台本身只講 HotSync，所以其他唔係我哋 target 嘅 Palm OS 機都一樣可以用 — 我哋只係唔會替佢哋做測試。
• Palm 機保持 Palm 機。 我哋不會推 custom firmware。平台講嘅係現有 HotSync 協議，對住現有 PalmOS app。如果某個 model conduit 唔通，我哋會修 conduit — 唔會改 Palm 嘅 app。

packages/android/ 入面正在準備一隻叫 Palm Organizers 嘅 Android 原生 app — 用 Capacitor 包住 SvelteKit Organizers shell，等同一個介面可以喺手機上跑。狀態：scaffold 階段。

PalmVellum 是一个开源平台，为 1996-2003 年那批 Palm Pilot 的原生 app 加入 AI 辅助和云端同步 — Palm 机本身完全不需要改动。

你选 Palm 是因为它安静。两节 AAA 电池。160×160 黑白屏。没有常驻通讯。没有摄像头。没有无限滚动。拿上手写东西，写完放下。平台在后台保存云端副本，要用 AI 时才取出来。

不是说品质低。不是为复古而复古。Low-fi = 低保真，有意为之。 像素少一些、通知少一些、让你拿起设备的理由少一些。平台只在 AI 和云端真正有用的地方介入 — 自然语言输入解析、手稿识别、每日新闻摘要、自动执行任务／日程 — 然后止步。我们不追踪你的阅读习惯，不卖广告，不会因为「有人看过你的 profile」推送通知。根本没有 profile。

两边（Palm 和平台）每个用户共享一个数据集。同一个家庭几部 Palm，读写同一组 records。

帮你慢慢累积一份有意识的个人记录 — 日程、联系人、记事、手稿、研究摘要、开支 — 又不会被自己的工具不断打断。Palm 机是 AAA 电池支撑的冷存储，平台保存云端副本和负责 AI 辅助。

• AAA 电池 Palm (1996-2003) 是我们的参考目标和设计重点 — 那是我们相信、会亲自测试的机型。但平台本身只讲 HotSync，所以其他不是我们 target 的 Palm OS 机都一样可以用 — 我们只是不会替它们做测试。
• Palm 机保持 Palm 机。 我们不会推 custom firmware。平台讲的是现有 HotSync 协议，对着现有 PalmOS app。如果某个 model conduit 不通，我们会修 conduit — 不会改 Palm 上的 app。

packages/android/ 中正在准备一款叫 Palm Organizers 的 Android 原生 app — 用 Capacitor 包装 SvelteKit Organizers shell，让同一个界面可以在手机上运行。状态：scaffold 阶段。
