Comparing two different implementations

[klonuo]

In branch-1 I have one implementation of a problem and in branch-2 another implementation of the same problem. Both branch from dev branch

Ocr provides review for specific commit or between two branches (i.e. main and branch-1)
How to compare 2 different implementations in branch-1 and branch-2?

Hi @klonuo, thanks for the question!

OCR doesn't currently have dedicated support for this scenario. It's designed to review a specific commit or the diff between a branch and its base (e.g. main...branch-1), so it always reviews changes relative to a baseline rather than comparing two alternative implementations against each other.

For comparing two different implementations of the same problem (like your branch-1 vs branch-2), I'd suggest reaching for a general-purpose coding agent such as Claude Code, Codex, or OpenCode. You can point it at both branches and ask it to compare the approaches, weigh trade-offs, and recommend one — that kind of open-ended, side-by-side reasoning is a better fit than OCR's diff-based review flow.

Hope that helps!
