Context

Fathom's development started before Microsoft acquired GitHub, and one of our ambitious objectives was to modernise the code review workflow while adapting the UI to support novel AI features.

Limits

Fathom lets you review files writen in any language, but the AI models only provide insights for the language they've been trained on, namely JavaScript. The GitHub integration, although supporting many use cases, also comes with own limits. In particular, Fathom users may need to switch back to GitHub's UI to benefit from the GitHub Marketplace.

Potential

We expect GitHub and its close competitor GitLab to eventually offer much more power and flexibility to third-party tools, and in this context, Fathom's core functionalities could be distributed an add-on to a platform that developers already love.
