About Lihai La

A Delaware software company with a short list of products and a long memory for the details.

Lihai La LLC builds and ships its own software. There is no client work and no roadmap dictated from outside — every app here exists because we wanted it to and could not find a version of it we liked.

That shapes what the apps are. They do one thing, they open fast, and they ask for as little as they can get away with: no account where an account is not needed, no cloud where the phone will do, no subscription for something you use in bursts. Three of the six have no networking code at all.

We build natively for each platform rather than wrapping one codebase six ways, which is why SuiSui feels like a Mac app on a Mac and a HarmonyOS app on HarmonyOS.

Founded: Delaware, United States
Products: Six, shipping
Platforms: iPhone · iPad · Android · Mac · HarmonyOS · Chrome & Edge
Business model: Paid apps, one-off unlocks and credits — no ads, no data sold

Questions

What is Lihai La?

Lihai La LLC is a software company based in Delaware, United States. It builds and ships its own apps: Ultimate Book Writer (AI book writing), LiveTranslate (live translated captions in Chrome and Edge), Parrovo (live translated captions on the Mac), SuiSui (countdowns and anniversaries), Annua (subscription tracking) and Rungs (ranking anything by comparison) — plus KiteGEO, a web tool that checks whether AI assistants recommend your brand.

Which platforms do Lihai La apps run on?

iPhone, iPad, Android, Mac, HarmonyOS, and the Chrome and Edge browsers. Each app is built natively for its platform rather than wrapped from one shared codebase.

What is KiteGEO?

KiteGEO (lihaila.com/geo) checks how visible a brand is in AI assistants. It asks ChatGPT and Grok — or DeepSeek and Qwen for Chinese users — the questions real buyers ask, scores how often the brand is mentioned and recommended, and gives an action plan to improve it. The first check is free.

How do Lihai La apps make money?

Paid apps, one-off unlocks and credits. There are no ads, and no user data is sold.

Do I need an account to use the apps?

Only where an account is genuinely needed. Three of the six apps have no networking code at all and keep everything on your device.
