Question: Is there a platform that can simplify and debug my code, and also explain syntax errors in a way I can understand?

SourceAI is a good option. It uses sophisticated AI to generate code from human language instructions, simplify code and correct errors, and debug code. Its interface is simple enough that nonprogrammers can use it. SourceAI can explain syntax errors and also can generate code to calculate factorials and generate Fibonacci sequences.

Another powerful option is Kodezi. The tool automates code correction, debugging and optimization for more than 30 programming languages. It explains errors in detail so you can maintain professional coding standards. Kodezi also can generate code from PDF files, translate code and generate documentation, so it's a good all-purpose tool to speed up coding.

For a general-purpose coding assistant, check out Codeium. It supports more than 70 programming languages and works with popular IDEs. Codeium offers advanced code completion, AI-powered search and an AI chat assistant that refactors code, generates documentation and explains code. Its tiered pricing plans make it useful for solo programmers and teams.
