⭐️ Why did they start cubic?
The team is made up of engineers who faced this problem when they worked together in the past. As they adopted more AI code gen tools, code review and ensuring quality quickly became their biggest bottleneck.
They had more PRs to review, subtle AI-written bugs slipped in, and they (humans) found themselves rubber-stamping PRs without deeply understanding the changes.
👷 They are building cubic to help solve that. Here’s how it works:
- Connect your GitHub repo via their Github app in two clicks
- AI review: When you open a PR, their AI reviews your changes directly in a secure container. It has context into not just that PR, but your whole codebase, so it can pick up patterns and leave comments directly on changed lines. Once the review is done, the sandbox is torn down and your code deleted.
- Human-friendly review workflow: Jump into their web (or desktop) app (it’s like Linear but for PRs). Changes are grouped logically (not alphabetically), with important diffs highlighted, visualized, and ready for faster human review.
💻 The AI reviewer works a bit like Cursor in the sense that it navigates your codebase using the same tools a developer would—like jumping to definitions or grepping through code.
⚡️ The platform itself focuses entirely on making human code reviews easier. A big inspiration came from productivity-focused apps like Linear or Superhuman, products that show just how much thoughtful design can impact everyday workflows. They wanted to bring that same feeling to code review.
That’s one reason they built a desktop app. It allowed them to deliver a more polished experience, complete with keyboard shortcuts and a snappy interface.
They think the future of coding isn’t about AI replacing humans—it’s about giving us better tools to quickly understand high-level changes, abstracting more and more of the code itself. As code volume continues to increase, this shift is going to become increasingly important.
