Frequently Asked Questions
How do I generate code with AI for free?
Simply describe what you want in the text box, select your programming language, and click Generate. No signup, no payment - just instant code generation. You can generate unlimited code for free.
What programming languages does the AI code generator support?
We support 50+ languages including JavaScript, Python, Java, C++, C#, PHP, Ruby, Go, Rust, Kotlin, Swift, TypeScript, SQL, and frameworks like React, Vue, Django, Flask, Express, Spring Boot, and more.
Is the AI-generated code safe to use in production?
The AI generates production-quality code following best practices, but we always recommend reviewing generated code before deploying. The code includes proper error handling, comments, and follows language-specific conventions.
Can AI generate code from natural language descriptions?
Yes! Describe what you want in plain English like "create a function that sorts an array of objects by date" and the AI generates the corresponding code in your chosen language with proper syntax, logic, and documentation.
Is there a limit to how much code I can generate?
No limits. Generate as much code as you need for free. There are no daily caps, no signup requirements, and no premium tiers blocking features. Use it for personal projects, learning, or professional development.
How is this different from GitHub Copilot?
Unlike Copilot which requires a paid subscription ($10-19/month) and IDE integration, Filator is completely free, works directly in your browser with no installation, and doesn't require any account. Perfect for quick code generation without setup.
Privacy & Security
Your Code Stays Private: We don't permanently store your prompts or generated code. Each request is processed and results are delivered directly to you - nothing is saved to our servers after your session.
No Account Required: Start generating code immediately. No email, no registration, no tracking. Just open the tool and create.
Pro Tips for Better Code Generation
Be Specific: Instead of "create a function", say "create a function that validates email addresses using regex and returns a boolean".
Mention Edge Cases: Tell the AI about edge cases you want handled, like "handle null values" or "throw error on invalid input".
Specify Framework: If you're using a specific framework, select it for optimized code that follows framework conventions.
Request Comments: Enable "Include detailed comments" for code that explains itself - great for learning and documentation.
Generate Tests: Enable "Generate unit tests" to get test cases alongside your code for better quality assurance.
