What is Liii STEM?
Liii STEM is a STEM writing platform designed specifically for formula-intensive fields like mathematics, physics, statistics, and computer science. It is built on a deeply optimized GNU TeXmacs core, integrating AI, large language model computing, and code execution environments. This significantly improves the editing efficiency of mathematical formulas, achieving speeds up to a hundred times faster than traditional . It also supports seamless export to standard format, meeting publication requirements.
Liii STEM features one-click typesetting, automatic formula proving, and algorithm explanation capabilities. These tools enable rapid construction of personal knowledge bases. Through visual language models (VLM), it efficiently recognizes handwritten formulas and note content. This fundamentally solves the time-consuming problems of formula derivation and typesetting. Liii STEM achieves a complete closed loop from research investigation and experimental verification to paper writing. It helps users focus on innovation while freeing them from formatting details, truly realizing "painless" STEM writing.
In addition to Liii STEM, we also maintain Mogan, a free community-oriented STEM writing platform that includes many of Liii STEM's features, except for large language model (LLM) integration and optical character recognition (OCR).
