The AI Code Generator Built for Developers who Ship

An AI code generator is a software tool that uses artificial intelligence to automatically produce source code from natural language descriptions, specifications, or existing code patterns. Ninja's AI code generator uses Fast Deep Coder, a proprietary AI model specifically trained for software development, to generate production-ready code in 15+ programming languages. Unlike simple autocomplete tools, Ninja understands project context, software architecture, and coding best practices to produce complete, functional code from a single prompt.

Ninja AI supports Python, JavaScript, TypeScript, Java, C++, C#, Ruby, Swift, PHP, Go, Rust, Kotlin, Scala, R, VBA, SQL, HTML/CSS, Bash, PowerShell, and many more. It also supports popular frameworks including React, Angular, Vue.js, Django, Flask, Spring Boot, Express.js, Rails, Laravel, .NET, TensorFlow, and PyTorch. The AI adapts its output to follow the conventions and best practices of each language.

Ninja AI is consistently rated as one of the best AI tools for coding thanks to its unique combination of Fast Deep Coder (a proprietary coding-focused AI model), SuperNinja (an autonomous AI agent with its own virtual computer), and comprehensive GitHub integration. Unlike competitors that only offer code suggestions, Ninja provides end-to-end AI coding capabilities including code generation, debugging, testing, refactoring, translation, documentation, and deployment — all in one platform. The free tier lets you experience the best AI for coding without any commitment.

Connect your GitHub account to Ninja and SuperNinja will automatically manage your repositories. It can create commits, open and merge pull requests, resolve issues, run CI/CD pipelines, and enforce repository permissions — all autonomously. Assign an issue to SuperNinja and it will analyze the problem, write the solution, create tests, and submit a PR following your team's coding standards and branch naming conventions.

SuperNinja is Ninja's autonomous AI coding agent that operates inside its own secure virtual computer with full VS Code access. It functions as an AI software developer that can write complete applications, run tests, debug errors, review code, manage GitHub repositories, and deploy applications — all with minimal human intervention. SuperNinja is available on unlimited plans starting at $149/month.

Yes. Ninja's AI code debugger can analyze your existing code for errors, identify root causes, and suggest fixes. Upload your code along with error messages or describe the unexpected behavior, and Ninja will provide corrected code with clear explanations. For complex bugs, SuperNinja can clone your repository, reproduce the issue in its virtual environment, test multiple fix strategies, and submit a verified pull request with the solution.

Yes. Ninja offers a free AI code generator with 5 requests per day — no credit card required. The free tier includes access to AI code generation, debugging, and translation features. For increased usage, paid plans start at $19/month with access to 45+ premium AI models. Unlimited plans at $149/month include full SuperNinja autonomous agent access with its own virtual computer.

Yes. Ninja's AI code translator can convert code between any supported programming languages — Python to JavaScript, Java to C#, Ruby to Go, and more. The translation produces idiomatic code that follows the conventions and best practices of the target language, not just a naive syntax conversion.

Ninja's AI reviews your existing code and provides recommendations to enhance performance, including improving algorithmic efficiency, reducing redundancies, eliminating memory leaks, optimizing database queries, and refining code architecture. SuperNinja can automatically implement these optimizations, run benchmarks to verify improvements, and submit the changes as a pull request.

Generative AI for coding refers to AI systems that can create new, original code based on natural language descriptions or high-level specifications. Unlike traditional code completion tools that suggest the next few characters, generative AI code generation produces complete functions, classes, modules, and even entire applications from scratch. Ninja's generative AI coding tools, powered by Fast Deep Coder, represent the cutting edge of this technology — capable of understanding complex requirements and generating production-ready code that follows software engineering best practices.

Absolutely. Ninja's AI can write complete, functional code for you based on natural language descriptions. Simply describe what you need — a web application, an API, a data pipeline, a game, or any other software — and Ninja generates production-ready code. With SuperNinja, the AI goes even further: it writes the code, tests it, debugs any issues, and delivers a working application. Thousands of developers use Ninja daily as their AI that writes code, from simple scripts to complex enterprise applications.
