Frequently Asked Questions
Who is this tool for?▼
Anyone who needs to understand unfamiliar code — developers reviewing a PR, students learning from examples, engineers onboarding to a new codebase, or anyone debugging code they didn't write.
How detailed is the explanation?▼
Use 'Detailed' mode for a section-by-section breakdown of every function, class, and logical block. Use 'Overview' mode for a high-level summary when you just need to understand the general purpose quickly.
Can it explain complex algorithms?▼
Yes. DeepSeek identifies algorithms like merge sort, dynamic programming, BFS/DFS, and many others. It explains both what the algorithm does and how it's implemented in the specific code you paste.
Does it detect bugs?▼
Yes — the Issues tab shows potential bugs, performance problems, security vulnerabilities, and style issues. This is not a substitute for a full static analysis tool, but it often catches common mistakes.
Which languages are supported?▼
TypeScript, JavaScript, Python, Go, Rust, Java, C#, PHP, Ruby, Swift, Kotlin, and C++. Select your language before explaining so the AI applies the correct context and idioms.
Is my code stored?▼
No. Your code is sent to DeepSeek's API, processed, and immediately discarded. We never store code on our servers and it is not used to train AI models.
