One keyboard.
Every language.
No switching.
一个键盘,
所有语言,
不用切换。

Chinese pinyin, an English term, a Spanish phrase: type them as one stream. SpaceFreeIME offers one mixed-language sentence. The local engine responds first; your own ChatGPT account can refine longer sentences. 中文拼音、英文术语、西语短句,想到什么就接着打。SpaceFreeIME 给出一条混合语言的候选句:本地先响应,长句再由你自己的 ChatGPT 账号补正。

macOS 13 or later · Apple Silicon · The local engine works offline. AI mode needs a beta code from us plus your own ChatGPT sign-in. macOS 13 及以上 · Apple Silicon · 本地引擎离线可用。AI 模式需要我们发的内测码,加上你自己的 ChatGPT 登录。

Mock-up. Inputs and outputs are demonstration examples, not a recording of the shipping engine.示意图。输入与输出均为演示用例,不是实际引擎的录制。
The problem问题

Every keyboard switch breaks a thought.每切一次输入法,思路就断一次。

People who type in one Western language just type. Everyone else switches modes, converts, picks words one by one, then switches back. The switching is the tax.只打一种西文的人,打完就完了。其他人要切模式、转换、逐字选词、再切回来。切换本身就是那笔税。

Classroom课堂

Lecture in English, notes in Chinese, terms kept in English.英文授课,中文记笔记,术语还得保留英文。

By the time the keyboard is in the right mode, the lecturer is two points ahead.等键盘切到对的模式,老师已经讲到下两个知识点了。

Chinese-speaking supervisor. English- and Spanish-speaking crew. Coordination by text.中文主管,英语和西语的班组,靠文字协调。

Wrong mode means retyping the whole message. This is the plant where the product was first felt as a need, not an idea.模式一错,整条消息重打。这个产品最先是在那个车间里被“需要”出来的,不是想出来的。

How it works怎么工作

You type naturally. SpaceFreeIME resolves the language.你照常输入,语言交给 SpaceFreeIME 处理。

One input stream becomes one mixed-language sentence. The example below illustrates the experience, not a recorded engine result.一条输入流,得到一条混合语言的候选句。下面是体验示意,并非实际引擎录屏。

One input stream你只输入一条流 jintian de meeting gaidao mingtian, porfavor
One candidate sentence一条候选句 今天的 meeting 改到明天,por favor。
No mode switching不切输入法 No word-by-word selection不逐词选字 No mandatory spaces不强制空格
Local engine本地引擎

A candidate appears first, even offline.先给候选,断网也能输入。

On-device dictionaries segment and rank the stream without sending ordinary typing to SpaceFree. The exact release data and long-run speed are still being checked.设备上的词典负责分段与排序,普通输入不发送给 SpaceFree。最终词库和长时间速度仍在验收中。

AI layer · your accountAI 层 · 你的账号

Longer sentences can be refined later.长句随后补正,不挡住继续打字。

If you enable AI, the necessary text goes directly to the provider you connect with your own account. SpaceFree's invite service does not process that text.启用 AI 后,必要文字直达你用自己账号连接的服务商;SpaceFree 的邀请服务不处理这些正文。

Leave the text alone when unsure.拿不准就不动。

Plain ASCII passes through untouched, and when the engine cannot decide it prefers your text as typed over its own guess.纯 ASCII 原样通过;引擎判断不了时,宁可保留你敲的原文,也不硬猜。

Password fields are off-limits.密码框不碰。

Secure text fields get the plain system keyboard. Nothing is composed, nothing is sent.安全输入框只用系统原生键盘。不组词,不发送。

Measure before release.先验证,再发布。

Candidate changes are compared on pinned accuracy and runtime checks. The public installer opens only after its release gates and Mac installation checks pass.候选改动会经过固定的准确率与运行检查。正式安装包要等发布门槛和 Mac 装机检查通过后才开放。

By the numbers数据

Measured, not promised.量出来的,不是许诺的。

Field notes现场记录

Tested where the switching hurts most.在最需要切换的地方试过。

May 27, 2026, an auto-glass plant in Ohio: an informal on-site session with six people, Spanish-, English- and Chinese-speaking, typing on a laptop prototype. Bilingual users typed mixed sentences without touching a mode key and kept suggesting features. English-only users felt much less difference, which is exactly what we expected.2026 年 5 月 27 日,俄亥俄一家汽车玻璃厂:六个人的非正式现场试用,说西语、英语和中文,在笔记本原型上打字。会两种语言的人不碰切换键就打出了混合句子,还不停提建议。只说英语的人感觉差别小得多,这正是我们预期的。

“This system is excellent. It separates words, corrects spelling, and inserts punctuation.” “这个系统很出色。它会分词、纠正拼写、插入标点。” Spanish-speaking user, translated. On-site session, Ohio, May 27, 2026.西语用户,译文。俄亥俄现场试用,2026 年 5 月 27 日。

FAQ常见问题

Straight answers.直接回答。

Which languages and platforms?支持哪些语言和平台?

Today: macOS 13 or later on Apple Silicon. Chinese pinyin, English, Spanish, French, German and Japanese romaji can be mixed in one sentence. iOS, Android and Windows ports run the same engine and are in development; there is no date yet.目前:macOS 13 及以上,Apple Silicon。中文拼音、英语、西班牙语、法语、德语、日语罗马字可以混在一句里。iOS、Android 和 Windows 版跑同一套引擎,正在开发,还没有日期。

Does it need the internet?必须联网吗?

No. The local engine does everything offline. A beta activation code plus your ChatGPT sign-in adds the AI sentence mode for longer, mixed sentences.不用。本地引擎离线完成全部工作。有内测激活码并登录 ChatGPT 后,长句和混合句会多一个 AI 整句模式。

Can you read what I type?你们能看到我打的内容吗?

Ordinary local typing stays on your Mac. If you enable AI, the necessary input and context go directly to the AI provider you choose through your own account; SpaceFree does not proxy those model calls. Our invite service receives license requests, not typed text. Optional coarse product analytics will require separate consent and are not enabled for this public waitlist.普通本地输入留在你的 Mac 上。若启用 AI,必要输入和上下文会通过你自己的账号直接发给所选 AI 服务商;SpaceFree 不转发模型请求。我们的邀请服务只接收资格请求,不接收输入正文。可选的粗粒度产品统计需要单独同意,在这个公开等候页面上尚未启用。

Why sign in with my own AI account?为什么要用我自己的 AI 账号?

You keep control of your provider account, model access and limits. AI requests go directly from your Mac to that provider instead of through a SpaceFree text server. The invite only controls eligibility for the AI feature.服务商账号、可用模型和额度仍由你自己掌控。AI 请求从你的 Mac 直达服务商,不经过 SpaceFree 的文字服务器;邀请码只用来核对 AI 功能的测试资格。

Intel Macs?Intel 的 Mac 能用吗?

Not yet. The beta ships for Apple Silicon only.暂时不能。内测版只提供 Apple Silicon 版本。

Is it patented?有专利吗?

Three U.S. provisional applications were filed pro se between September 2025 and May 2026, covering space-free whole-sentence decoding, provider-agnostic BYO-AI routing, and hardware-key-position layout decoding. The first has lapsed; two remain on file. Provisional applications are not granted patents and confer no enforceable rights.2025 年 9 月到 2026 年 5 月间自行递交了三项美国临时专利申请,涵盖无空格整句解码、不绑定服务商的 BYO-AI 路由、按键物理位置的键盘布局解码。第一项已失效,两项仍在案。临时申请不是授权专利,不产生可执行的权利。

Who makes it谁在做

One person, on the floor and in the code.一个人,在车间里,也在代码里。

SpaceFreeIME is built by Jerry (Jinyu) Liu. He worked at Fuyao Glass America, first as a production intern in summer 2025 and later as a shift supervisor in 2026, where a Chinese-speaking supervisor and an English- and Spanish-speaking crew coordinated by text all day. He wrote the first prototype in September 2025 to stop switching keyboards himself. He is now a Master of Quantitative Management student at Duke University's Fuqua School of Business.SpaceFreeIME 由 Jerry(刘谨瑜)开发。他在 Fuyao Glass America 工作过,2025 年夏天是生产实习生,2026 年做轮班主管;那里的中文主管和英语、西语班组整天靠文字协调。2025 年 9 月他为了自己不再切键盘写了第一版原型。他现在是杜克大学 Fuqua 商学院量化管理硕士(MQM)在读。

The product is built with written specifications, tests and release gates. I use coding agents to implement ideas, then verify the result against fixed accuracy, performance and installation checks.产品从书面规格、测试和发布门槛开始。我用编程代理实现想法,再用固定的准确率、性能和装机检查核对结果。
