I think the tldr would be that they have more products (for example, their agent to write git commit messages). In the products we do have (autocomplete, chat), we spend a lot of time to get the details right. For example for autocomplete:

* we always close any brackets opened by autocomplete (and never extra brackets, which is the most annoying thing about github copilot)

* we automatically add import statements for libraries that autocomplete used

* mid-line completions

* we turn off autocomplete when you're writing a comment to avoid disrupting your train of thought

You can read more about these small details here: https://docs.double.bot/copilot

As you noted we don't have a vim integration yet, but it is on our roadmap!

Do note that Codium and Codeium are two completely separate companies. They work in related fields but have very different approaches.

Wow you are right. That is confusing! I was asking about Codeium (with an e) but I linked the wrong one in my post. The vim plugin link is correct though.
