Our Products
Aiyo.app is an AI chatbot built on a LINE Official Account. It is completely free to use and allows you to choose from online models such as gpt-5 and Gemini, or self-hosted models such as gpt-oss and gemma-3. It supports multiple input types, including text, images, voice, and GPS location. It also comes with built-in tools for real-time web search, up-to-date Taiwan local arts and cultural events, real-time news summarization, and more.
“utunote e-Invoice Management System” has been reviewed and approved by the Ministry of Finance’s e-Invoice Center and supports the latest e-invoice “M.I.G 4.1” transmission format, providing fully automated, end‑to‑end e-invoice processing. Unlike typical providers that only support issuing B2B (business-to-business) invoices, the “utunote e-Invoice Management System” can issue and manage the full range of B2B and B2C invoices, and it supports all e-invoice Turnkey transmission methods, including exchange e-invoice and storage e-invoice, enabling seamless integration with your existing systems.
AiyoDesk is an integrated toolkit built around llama.cpp, released as free and open-source under GPL 3.0, enabling quick installation and automatic setup of software such as conda, Open WebUI, and ComfyUI to rapidly establish a local AI environment on a home PC. It is an experimental project distilling our hands-on experience with on-prem AI integration, and a new, improved version is being planned to deliver a better user experience.
