Startup Denigma introduced an AI service that can comment on code and help developers deal with someone else’s code. It can:

• Fix bugs faster Rapidly and automatically drill down into bugs for a deeper technical understanding. Navigate your code faster than ever before.
• Dive deep into third-party libraries. Fearlessly understand open-source libraries.
• Rapidly understand unfamiliar codebases. New developers can onboard faster, with less assistance from developers already on the project.
• Gain insight into legacy code. Understand what you didn’t know you didn’t know. Denigma puts old code in a new light.
