The story behind iolys
Find your bearings in a changing AI world.
AI moves fast. Your workspace can remain familiar. iolys helps you explore models and providers while keeping your code, your tools, and your workflow in Visual Studio.
A name inspired by iolite
The name iolys takes its inspiration from iolite, a blue-violet stone associated with the story of the Viking sunstone. The idea is compelling: a stone that could help a navigator find the sun, even when clouds obscured it. Whether Vikings actually used iolite this way remains uncertain. For iolys, that image of finding a direction is the inspiration.
A guide through the AI chaos
New models, new providers, new ways to work: the choices keep multiplying. iolys brings them into a familiar workspace so you can focus on what you want to build. Like the stone that inspired its name, it is a point of reference when the landscape is hard to read.
Your bearings stay in Visual Studio
Your solution, editor, debugger, and everyday C# and .NET workflow stay in Visual Studio 2026. You can change the AI you work with without changing your development environment. That continuity is the idea behind iolys: let AI evolve around a workspace you already know.
Choose your provider. Keep your course.
Use the supported provider and model that fit the task: an eligible subscription, a cloud API, an enterprise connection, or a local model. iolys gives you a common place to work with those choices, with visible tool activity and permission controls. Let iolys guide you through the options. You decide the direction.
