Language overview
Delphi programming language
Delphi is both an object-oriented programming language (Object Pascal) and a rapid application development (RAD) IDE from Embarcadero. Evolving from Borland’s Turbo Pascal, Delphi offers a strongly typed language with native compilation and a rich component library (VCL for Windows, FireMonkey for cross-platform GUI). It excels at building high-performance desktop, mobile (iOS/Android), web, and console applications, with built-in database connectivity, visual designers, and a robust runtime library.

- Step 1
Add your Delphi code
Type, paste, or upload the Delphi code you want to check.
- Step 2
Run the check
Click Check Code to analyze the code and identify potential issues.
- Step 3
Review the results
Review the issues found, suggested fixes, and corrected code.
Why use the checker
How is this different from a linter?
Traditional Delphi linters check syntax and basic style against predefined rules. This AI code checker also understands your code’s logic, helping it find semantic bugs, performance problems, security concerns, and best-practice violations.
Common questions
Frequently Asked Questions
How do I check Delphi code for bugs using CodeConvert AI?
Simply paste your Delphi code into the input box and click the Check Code button. Our AI will analyze your Delphi code for bugs, performance issues, readability problems, and best-practice violations, then provide corrected code in seconds.
What kinds of issues can this tool find in Delphi code?
This tool can find a wide range of issues in Delphi code, including logic errors, off-by-one bugs, null/undefined access, type mismatches, performance bottlenecks, readability problems, deprecated API usage, security concerns, and violations of Delphi best practices.
Does it fix Delphi code or just report issues?
Both. The tool identifies each issue with a severity level and explanation, provides a code snippet showing the fix, and includes a complete corrected version of your Delphi code with all fixes applied.
How is this different from a Delphi linter?
Traditional Delphi linters check for syntax errors and basic style violations based on predefined rules. This AI code checker understands your Delphi code's logic and can find semantic bugs, suggest performance optimizations, identify security concerns, and explain issues in plain English — going far beyond what static analysis tools can detect.
Can I also convert or explain my Delphi code?
Yes! After checking your Delphi code, you can use our free Code Converter to translate it to any of 50+ other programming languages, or use the Code Explainer to get a step-by-step breakdown of how it works. Try the Delphi Code Explainer
