AIXtal is an accessible refinement platform designed specifically for first-time users. It includes a simplified user interface with reduced complexity, tutorials, tooltips and AI helpers for assistance. Currently, AIXtal supports GSAS-II and Fullprof (undergoing a refactoring) refinement of powder X-ray diffraction data.

AIXtal v2 is currently being developed based on the experience from AIXtal v1 and in order to broaden the use case scenarios. With multiple modes of operation, adding an expert mode with full refinement control to the simplified interface, it opens up for future developments of a more universal GUI for Rietveld programs also addressing other common, related crystallographic issues, e.g., a space group prediction. Furthermore, the web interface now runs on WebAssembly, which promises performance gains, and moreover now runs not only in the WebBrowser but also natively on Windows and Linux to allow a local installation as well. The GSAS-II implementation has also been extended to support refinement and visualization of multi-dimensional (angular and wavelength dispersive) data sets.
