Engineering That Scales

Test Everything

Engineers are not known for their meticulous testing. Fume will test for edge cases for each PR, understanding context around the changes.

Scale Review

Most teams are bottlenecked by code review. Infintely scale your ability to review code as the team grows.

Actionable Comments

Not only Fume reviews code, but it suggests multi-file, tested changes that you can commit with a single click.

Shadow Engineering Workforce

Fume works silently in the background, handling the most tedious work for your team. Right now, it's testing but it will soon be able to do much more. For an AI agent with a computer, the sky is the limit.

Review Your Way

Equip Fume with tribal knowledge via either playbooks or web recordings.
