Since we are talking about Python type-checkers: we've built a (non-AI based) type assistant for Python called RightTyper (https://github.com/RightTyper/RightTyper https://github.com/RightTyper/RightTyper). Below is a brief description; a technical paper describing RightTyper is here: https://arxiv.org/abs/2507.16051 https://arxiv.org/abs/2507.16051, "Getting Python Types Right with RightTyper" RightTyper is a Python tool that automatically generates type annotations for your code. It monitors your program as it runs and records the types of function arguments, return values, local variables, and class fields — with only about 25% runtime overhead. This makes it easy to integrate into your existing tests and development workflow, and lets a type checker like mypy catch type mismatches in your code.
