What does it do for me?
Shows you what changed since last time you looked. Even across multiple commits, merging, or rebasing. In beautiful, responsive, one- or two-column diffs.
Manages comments so your inbox doesn't overflow. Send comments in batches to structure the review process. Never miss a comment or have it mysteriously disappear.
Integrates effortlessly with GitHub pull requests. No new commands to learn, no separate repos to sync, no servers to set up. Live updates. Two clicks to set up.

“It seems that the tools for code review in GitHub are not great, to put it lightly. Not great at all.”

BTW Reviewable is really awesome.
After using it for a few reviews now, I hate going back to GitHub.

I've gotta say—Reviewable is the best damn code-review tool out there.
Super slick, silky-smooth integration into GitHub. Love it.

Reviewable is working really well for us so far. We’re migrating from a self-hosted Gerrit installation and Reviewable gives us most if not all of the benefits while integrating much better with the GitHub workflow developers are used to.

Reviewable is freaking awesome, BTW.
