关于念匣About Nianbox
念，是一闪而过的念头，也是放在心上的惦念。匣，是用来收好珍重之物的小盒子。念匣，就是把转瞬即逝的念头，放进一个可靠的小匣子。
念匣起于一个很具体的愿望：想到事情的时候，掏出手机就能说；说完之后，声音和文字都还在。很多闪念工具要先登录、先付费，或者把录音交给云端才肯干活。念匣反过来做：不需要账号，按下就录，录完先把声音存好，再在 iPhone 上把它变成可以编辑、搜索和整理的文字。
它也会慢慢学会你的说话方式。工作里的品牌名、家里人的称呼，各自放在自己的项目里；你明确确认过的纠正，下次才会被记住，而且不会串到别的场景。
AI 怎么工作
在支持 Apple Intelligence 的 iPhone 上，标题、摘要、整理和问答由设备端模型完成，内容不离开手机。设备端 AI 不可用时（例如设备或地区不支持），录音、转写和搜索照常可用；你也可以添加自己的 AI 服务，例如通义千问、DeepSeek、OpenAI 或自建服务。内容由你的 iPhone 直接发给你选择的服务，不经过我们。

In Chinese, niàn (念) is a passing thought, and also someone you keep in mind. Xiá (匣) is a small box for things worth keeping. Nianbox is a dependable little box for thoughts that would otherwise slip away.
It started with a simple wish: when something comes to mind, take out your phone and say it, and afterwards the audio and the text are both still there. Many quick-capture apps ask you to sign in, pay, or upload your recordings before they do anything. Nianbox works the other way round: no account, tap and talk, the audio is saved first, and then your iPhone turns it into text you can edit, search and organize.
It also learns how you speak. Brand names from work and the names you use at home stay in their own projects. A correction is remembered only after you confirm it, and it never leaks into another context.
How the AI works
On iPhones that support Apple Intelligence, titles, summaries, templates and answers are produced by the on-device model, and your content stays on your phone. When on-device AI isn’t available (for example, on unsupported devices or in unsupported regions), recording, transcription and search still work, and you can add your own AI service, such as Qwen, DeepSeek, OpenAI or a self-hosted server. Your iPhone sends content directly to the service you choose, never through us.
The icon
The outer stroke of the character 匣, “匚”, is itself an open box. Inside it sits a sound wave.
