For data scientists, researchers, and analysts who want AI help within their analysis workflow, Lotas offers Erdos, an IDE designed for working with data rather than only general-purpose software development. It supports R, Python, SQL, and Julia workflows, with built-in language consoles, a plots pane, documentation search, database connections, and environment management. Its AI assistant can work with project context and help write or edit code as you explore data and review results. Erdos is suited to people working across scripts, notebooks, and other data-science files in one environment. Lotas also built Rao, an AI assistant integrated into RStudio. Rao can search project context, read and edit files, run code and commands, and interpret outputs such as errors and plots. It is aimed at R users who want coding assistance without leaving RStudio.
