Welcome to Newdi

Newdi writes the tests. You write the future.

Every great software product starts with a spark — an elegant algorithm, a clever abstraction, a beautifully simple API. But somewhere between concept and commit, that spark dims under the burden of unit tests.

Newdi is the world's most intelligent Java unit test generator. Not a tool, but a test-writing teammate. It understands your code, generates accurate and maintainable tests, and keeps them fresh as your logic evolves. Save 240 hours per developer per year.

The Intelligence Behind the Magic

Newdi isn't just automation—it's artificial intelligence purpose-built for testing. Every decision is backed by deep understanding of code semantics, team patterns, and testing best practices.

1

Semantic Code Understanding

Our AI analyzes your code at a molecular level—understanding business logic, dependencies, exception flows, and architectural patterns. It builds a complete mental model of what your code does and why it exists, enabling intelligent test generation that goes far beyond simple pattern matching.
