Be careful. Code sent for analysis goes to an AI service, so strip credentials, API keys, connection strings and customer data first — and check your employer’s policy, since many prohibit sharing proprietary source with third-party tools. For learning, debugging isolated snippets and generating boilerplate, it is well suited.
Review it as you would a pull request from someone unfamiliar with your codebase. It is generally sound on common patterns and idioms, but it can invent library functions that do not exist, use outdated APIs, or miss edge cases and security considerations specific to your context. Always run it before trusting it.
Explain and Debug tend to earn their keep most — pasting an unfamiliar function or a cryptic stack trace and getting a plain-English breakdown saves real time. Convert is handy for porting between languages, and Test is good for generating a first set of cases you then extend by hand.
Yes, AI Dev Studio is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
AI Dev Studio sends your file to our AI provider over an encrypted connection so the model can process it. It is deleted after processing and is not used to train models. If a file is confidential, use one of our in-browser tools instead, which never upload anything.
