What It Is

Codespy (the page branding also shows AI Detector Pro) is an AI code detection tool built for code-related scenarios. Its main pitch is determining whether code was generated by models such as ChatGPT, Claude, Gemini, or GPT-4. It is not a traditional static security scanner; instead, it uses AI-likelihood reports/heatmaps to help reviewers locate codebase sections that are more likely to be AI-generated and therefore deserve closer review.

Core Capabilities and Use Cases

Based on the collected information, Codespy supports mainstream languages including JavaScript/TypeScript, Python, Java, PHP, C/C++, and C#, and claims it can detect AI-generated code with 98% accuracy. Typical use cases include checks before PR merges, pre-release code review, helping security teams focus on higher-risk changes, and helping engineering managers define AI coding policies. The page cites Apiiro research to emphasize that AI-assisted development may increase the burden on security reviews, so Codespy is positioned more as a “review prioritization tool.”

Pricing and Trial

It offers free instant scans: users can paste code and receive a visual report before registering, with no credit card required. Registration is only needed after reaching the scan limit. The free plan is listed as including 10 AI scans per month, with unused scans rolling over. The page includes a monthly/annual billing toggle, but the captured content does not contain full paid pricing or plan benefits, so enterprise buyers should still confirm costs before procurement.

Pros and Cons

Its strengths are its focus on code detection, broad language coverage, low barrier to entry, and mentioned integrations with VS Code and ChatGPT plugins, making it suitable for embedding into developer workflows. The drawbacks are also clear: AI code detection is inherently prone to false positives or false negatives. Although the page claims 98% accuracy, it does not disclose the evaluation dataset, false-positive/false-negative rates, or third-party validation. It also does not clearly explain policies around uploaded code storage, retention, use for training, or compliance, which is a critical risk for teams handling private code.

Who It’s For and Access from China

Codespy is better suited to software teams, engineering managers, and security reviewers that already use AI coding tools and want to establish a review process. Individual developers can also use the free scans for quick checks. There is no clear information about access from mainland China, supported payment methods, or a Chinese interface; Chinese is not visible in the language list. Local teams should therefore evaluate network accessibility, payment convenience, and whether code review/security scanning tools should be used as an alternative or supplement.
