XICO is an AI and software company in Guangzhou. We build and run Xico Clean, XICO Store and Machi, and we develop AI applications and custom software for clients. Your project gets the same care as our own products.
Xico Clean, XICO Store and Machi are built and run by XICO — a desktop app, a commerce platform and a mobile app. The most direct way to judge our work is to use them.

New practice · In preparation
We are bringing what we have learned in native development, graphics and interaction into games. The work is still in preparation — follow along, or get in touch about partnerships.
Every capability here is proven in our own products before it goes into client work.
We bring large language models into real work — assistants, knowledge-base search, content processing and automation — and own everything from solution design to evaluation. Machi AI and Xico Clean's similar-photo detection are the same skills at work in our own products.
LLM apps · RAG · On-device AI · Evaluation
macOS and iOS apps in Swift 6 and SwiftUI, deeply integrated with the system and tuned for performance. We take Xico Clean through every step ourselves: development, signing, Apple notarization and automatic updates.
Swift 6 · SwiftUI · macOS · iOS
Multi-platform development with Next.js, iOS and Android, covering admin consoles, payments, memberships and localization. XICO Store, Machi and this site all run on this stack.
Next.js · iOS · Android · Payments
Deployment, monitoring, data security and a steady release rhythm are part of every delivery. After launch, we stay responsible for how it runs.
Deployment · Monitoring · Data security · Maintenance
These principles come from building products every day, and they apply to every project we take on.
Before writing code, we pin down the goal, the users and the boundaries. A clear problem is what makes a timeline and a budget honest.
Interfaces, copy, error messages, loading speed — users feel all of it. We don't settle on any of these.
Data that can be processed locally stays local, and client data has clear permission boundaries. There is no compromise here.
Our own products keep getting updates; client projects get long-term maintenance. Handover is not the end of the relationship.
Our own products follow the same process, and every stage ends with something you can see.
We learn the background, goals and constraints, judge the scope and technical route, and give honest advice — including what not to build.
Information architecture, interactive prototypes and the technical plan come first, so risks surface before any code is written.
Work moves in versions with transparent progress, and each stage ends with something you can try and sign off.
Deployment, monitoring, fixes and iteration. After launch, we are still here.
Our products and our client projects follow one standard: clear structure, solid performance and long-term maintainability. That is what lets software hold up over time.
AI is changing how software is made and what it can be. We use it in our own products first, and bring it to clients once it has proven its worth.
