What it does

Callstack.ai Code Reviewer reviews pull requests with the aim of cutting review time and the risk of problems reaching production. It is built on its DeepCode engine, which the site describes as a code-focused retrieval approach that maps the hierarchies, structures and relationships inside your codebase. For each change it generates a summary and description of the changed files so a reviewer gets context quickly. It looks for bugs, breaking changes, slow code and departures from code conventions, and proposes fixes that can be committed as they are. Each issue is ranked by severity so the critical ones can be handled first. The home page gives a call to book a conversation or get a first review, and links to a pricing page, a demo and documentation, but it does not state prices or supported platforms.
