Shuangpin Layout Comparator

Help Chinese input users pick the right shuangpin layout with real data

Problem

Users want to learn shuangpin but find that promotion of each layout is heavily biased—mainstream LLMs give completely different conclusions once a bias-limiting prompt is added—and there is almost no objective side-by-side comparison. They also struggle with too many candidates and don't know which layout to switch to or how fast they really need to type for coding/research.

Solution

Run each major shuangpin layout against the same real-world corpora (code, technical docs, daily chat) to compute key-position stats, collision rate, candidate count, and left/right hand load, then generate an interactive comparison report. Include a unified typing-speed test and practice dashboard to track the learning curve of each layout.

Users

Chinese programmers, researchers, and writers migrating from full pinyin to shuangpin, plus heavy keyboard users who care about input efficiency.

MVP

Built-in keymaps for 5–8 mainstream shuangpin layouts; import user's own corpus to compute collisions and candidate counts; shareable side-by-side comparison charts; simple typing speed and accuracy test; local practice history.

Revenue

Free basic comparison + paid personalized layout recommendation report and long-term practice analytics subscription (~$3/mo); optional one-time purchase for advanced layout packs.

Why now

Shuangpin discussion is rising in Chinese developer communities, but data-driven evaluations are scarce and most existing content is promotional. An indie developer can build a credible comparison tool in two weeks using public corpora and simple scripts.
