Day 13 unlocks Duck Duck Code – an AI rubber duck debugger that helps you explain your problem, understand root causes, and ship the fix faster.
The Rubber Duck Debugging Method
Rubber duck debugging is a legendary technique: explain your code to a rubber duck, line by line, and often the bug reveals itself. The act of verbalizing forces you to think differently about the problem.
Duck Duck Code automates this process with AI. Instead of talking to a duck on your desk, you paste your code, describe your issue, and get back structured, actionable debugging help.
Two Response Modes
Speed Mode: Get straight to the solution. Paste your code, explain what’s broken, and receive a working fix with minimal explanation. Perfect when you’re in a time crunch.
Learn Mode: Understand why bugs happen. Responses focus 80% on explanation and 20% on code, with single-line code examples that illustrate concepts rather than show the entire solution. Great for leveling up your debugging skills.
Two Chat Modes
Paste Mode: Dump your code (functions, files, or snippets), describe the bug, hit send, and get analysis. Best for isolated problems.
Chat Mode: Have a conversation with the AI debugger. Ask follow-up questions, refine explanations, and iterate toward a solution together. Best for complex problems that need back-and-forth.
Three Storage Options
Browser: Chat history saved locally in your browser. Fast, private, but lost if you clear cache.
Database: Create a free account to save chats to our servers. Access your debugging history from any device. Token usage tracked automatically (15,000 tokens/day limit).
None: No storage. Each chat is ephemeral. Useful if you prefer zero persistence.
Daily Token Limits
Each account gets 15,000 free tokens per day (resets daily at midnight UTC). Tokens represent API usage – longer chats and more complex code analysis use more tokens. Most debugging sessions use 500-2,000 tokens.
Daily reset is automatic. No payment, no surprise overages, no hidden costs. Free accounts stay free.
Real-World Scenarios
- Off-by-one errors: Paste your loop and describe the behavior. Learn why it happens and how to fix it.
- Race conditions: Explain timing issues. Get help reasoning through async flows.
- API integration bugs: Share request/response examples and get error diagnostics.
- Performance problems: Submit slow code and learn where bottlenecks are hiding.
- Regex pattern fails: Test patterns and get explanations for edge cases.
- State management issues: Debug React, Vue, or Svelte state problems with AI guidance.
Privacy & Security
Code you share is only visible to you and our admins. We never use your code to train models or share it with third parties. All chats are encrypted in transit. Opt for “browser” mode if you prefer zero server storage.
Stop debugging alone. Explain your bug to Duck Duck Code and get unstuck in minutes.
