Gru.ai is a platform for building and using AI “developer” agents that help with real engineering work—from writing code to testing and debugging. It’s designed for professional teams that care about quality, reliability, and repeatable results.
AI developer for coding and tests
Gru acts like a virtual developer to support day-to-day development tasks:
- Write and refactor code
- Design algorithms
- Find and fix bugs
- Assist with testing and debugging
Gru Unit Test is a separate product that integrates with GitHub and automatically generates unit tests to increase coverage and speed up code review. It supports popular testing frameworks, and up to 80% of pull requests with generated tests are accepted without major changes.
