Detect whether code is human-written or AI-generated across major programming languages.
AI-assisted coding is now routine, but that creates a new problem. Teams often don’t know which parts of their codebase were written by humans and which were generated by AI tools. This matters for quality control, academic integrity, hiring assessments, and client trust. CodeSpy.AI is designed to solve that exact problem by identifying whether source code was written by a human or generated by AI, across major programming languages.
Is it worth using? If you review third-party code, manage teams that rely on AI coding tools, or assess originality in technical evaluations, CodeSpy.AI can add a useful verification layer. It’s not a replacement for code review, but it can highlight risk areas quickly.
Who should use it: developers, engineering managers, educators, recruiters, and agencies.
Who should avoid it: solo developers with full visibility into their own code or teams expecting perfect accuracy guarantees.
Modern development workflows increasingly mix human-written code with AI-generated snippets. That’s efficient, but it also introduces uncertainty. Bugs, licensing questions, and accountability issues often surface later, when it’s harder to trace the source. CodeSpy.AI fits into this gap as a verification tool rather than a policing mechanism.
In hands-on testing, the product feels intentionally narrow in scope. You paste or upload code, or integrate it into GitHub or VS Code, and receive a confidence-based assessment of whether the code shows AI-generated patterns. It doesn’t attempt to rewrite or “fix” the code, which keeps expectations realistic. The value is in early visibility, especially during reviews, audits, or evaluations.
Below is a detailed, practical review written for developers, educators, hiring managers, and engineering teams deciding whether this tool fits their stack.

Teams expecting 100 percent certainty or automated code correction
Developers looking for performance optimization or refactoring tools
Projects where AI usage is already fully disclosed and accepted

Paid plans start at $49.98 per month
Final rating
8.4 out of 10 (reviewer-based, due to limited independent public ratings)
This rating reflects solid execution of a narrow use case, transparent accuracy limitations, and practical integrations, balanced against the inherent uncertainty of AI detection.
CodeSpy.AI is an AI code detection tool that analyzes source code to estimate whether it was written by a human or generated by an AI model such as ChatGPT, Gemini, or Claude. It supports widely used languages including Java, Python, JavaScript, C++, C#, and PHP.
The core problem it addresses is verification. As AI coding tools become mainstream, organizations face new risks. AI-generated code can include subtle logic errors, insecure patterns, or stylistic inconsistencies that bypass traditional plagiarism checks. In education and hiring, the challenge is slightly different: verifying originality and effort rather than optimizing output.
Unlike generic plagiarism detectors, CodeSpy.AI focuses on structural and stylistic signals in code. It compares submissions against large datasets of known AI-generated and human-written code patterns. The output is a prediction with a confidence score, not a binary verdict.
What differentiates CodeSpy.AI from many alternatives is its workflow integration. Instead of being a one-off scanning site, it can run inside GitHub pull requests, Visual Studio Code, and via API, making it usable in real development pipelines rather than only audits.
At a high level, CodeSpy.AI is straightforward to use, even for non-specialists.
Typical workflow
Paste code directly into the web interface or upload a file
Or connect a repository through the GitHub integration
Or scan files directly inside Visual Studio Code
The system analyzes syntax, structure, logic flow, and stylistic markers
Code is compared against large datasets of AI-generated and human-written code
A confidence score indicates the likelihood of AI generation
The tool does not modify code or suggest fixes. It only flags probability. This design choice matters because it positions CodeSpy.AI as a decision-support tool rather than an authority. In testing, scan times were fast for small and medium files, making it usable during reviews without disrupting workflow.
AI vs human code detection
Quickly identifies whether code likely originated from an AI model, helping reviewers focus attention where risk is higher.
Multi-language support
Works across popular languages such as Python, JavaScript, Java, C++, C#, and PHP, which covers most mainstream stacks.
Confidence-based results
Outputs a probability score instead of a hard yes or no, allowing informed judgment rather than blind enforcement.
IDE integration
Visual Studio Code extension enables scans during development, not just after submission.
GitHub integration
Automatically scans commits and pull requests, useful for teams managing multiple contributors.
Reporting and exports
Branded and white-label reports support documentation needs for audits, education, or client communication.
API access
Enables automation in CI/CD pipelines or internal tools, particularly relevant for larger teams.
For developers
Review AI-assisted code from teammates or contributors and identify sections that need closer inspection.
For engineering managers
Establish guardrails around AI usage without banning it outright, improving accountability in delivery.
For educators
Check programming assignments for AI-generated content while acknowledging that detection is probabilistic, not definitive.
For recruiters and hiring managers
Validate take-home coding tasks where AI assistance is restricted or needs disclosure.
For agencies and freelancers
Provide evidence of originality when clients request human-written code.
For teams adopting AI coding tools
Understand where AI is used most and document internal guidelines based on real patterns.

On-premise and API-heavy use cases
Who should pay: teams reviewing code regularly or integrating detection into workflows.
Who should avoid upgrading: users needing only occasional checks.
No. The company explicitly states that no AI detection tool can guarantee perfect accuracy.
It supports most major languages, but niche or newer languages may not be covered.
No. It only detects and reports likelihood, leaving remediation to developers.
Yes, with limited monthly scans.
Yes, through API integration and GitHub workflows.
CodeSpy.AI is best suited for teams and evaluators who need visibility into AI-assisted code without banning AI outright. It works well as a verification layer in reviews, audits, and assessments, especially when combined with human judgment.
It’s not the right choice if you expect definitive answers or automated fixes. In those cases, traditional code review and testing remain essential. For organizations balancing AI adoption with accountability, CodeSpy.AI provides practical insight with minimal friction.
