Hey, so, Codii is much simpler under the hood: it’s core is a smart prompt + LLM model that runs on pull requests. It doesn’t yet have deep static analysis, embeddings, repo-wide understanding or customisable rules — but it focuses on delivering helpful, lightweight code reviews with minimal setup.

GitHub Copilot Reviews is much more integrated into the GitHub platform and can access richer context like the full diff, surrounding files, and maybe repo history. It’s probably more sophisticated behind the scenes.

That said, Codii is:

• Easy to install (just a GitHub app)

• Fast to iterate on (I can tweak the prompts based on feedback)

• Customizable (it’s mine, so I can steer it toward indie dev use cases like onboarding help or documenting design choices)

In terms of requests and pricing, I believe GitHub Copilot free is going to offer 2k completions and 50 chats per month per user starting May 2025, and offers a Pro plan @19$ per user I think where you actually get access to much more than just reviews just to be clear, whereas Codii for now will be free until I gather feedback, but will be limited to 200 scans per month per user. Planning to offer a paid plan soon around the ~10$ mark

TL;DR: Codii is like a minimalistic, customizable code review assistant powered by GPT — not as powerful as Copilot Reviews yet, but very easy to set up and iterate on
