CHAINFUN · SHENZHEN · SINCE 2018

We turn AI into products people actually use.

Seven years of software delivery underneath. On top of it, our own AI products — a keyboard that helps you say the right thing, GEO that gets your brand named by AI, and a dubbing engine that carries your voice across languages.

AI Keyboard

Say the right thing, in your own voice.

An AI communication assistant that lives inside your system keyboard. Summon it in WeChat, TikTok, WhatsApp or any chat app — it reads the room, remembers the relationship, and helps you reply just right.

How is GEO different from SEO?

SEO competes for a ranking in search results. GEO competes for the sentence inside an AI answer — whether the model mentions you, and whether it gets you right.

Can you get me "indexed" by ChatGPT?

No — nobody can. Large language models have no submission mechanism. What we can do is make sure AI finds you and describes you correctly when it searches the web.

How long does GEO take, and how is it proven?

The core package usually shows clear change in about four weeks. We re-run the same prompts and hand over before/after data, screenshots and reproducible prompts, so you can verify it yourself.
