Rubber Duck That Talks Back

Paste the stack trace that means nothing to you. Get what actually broke, why, and the most likely fix — in plain English.

Test's red and you don't know if it's the code or the test. Paste both — get whether the test is wrong, the code is wrong, and exactly what to fix.

Stop guessing. Give it the symptom and the code — it ranks the likely causes and tells you the one thing to test next. Diagnoses before it touches a fix.

Paste your code. It reviews like it's shipping to a million users tomorrow — bugs, security holes, the slow stuff — ranks every issue, and ends with ship or don't. No flattery.

That boring task you do by hand every week. Describe it — get a script to automate it, with setup steps simple enough that a non-coder can run it.

You know you should. Paste the function — get the test cases that actually catch bugs, including the edge cases you'd forget at 6pm.

Dropped into unfamiliar code? Paste it. Get the map — what it does, how it flows, and where the bodies are buried — before you touch a thing.

Got the logic in plain steps but not the syntax? Write it out however you think — get clean, working code in your language, with the logic preserved.

Paste the function you're embarrassed by. Get it cleaner and readable with the exact same behavior — plus a note on what was wrong so you stop doing it.

It works but it's slow. Paste it — get where the real bottleneck is, the optimized version, and whether the speed-up is even worth the complexity.

Describe what you want to match in plain words. Get the regex, every piece explained, and test cases — so you actually trust it before you ship it.

A config file full of settings you're scared to touch. Paste it — get what each part does, which knobs are safe to change, and which will break things.

The thing every dev skips. Tell it what your project does — get a README people can actually follow: what it is, how to run it, and why it exists.

Got dropped into a framework you've never used? Name it and what you know — get the mental model, the core concepts, and the 20% you need to be productive today.

Porting code to a new language or framework? Paste it — get the converted version plus the traps that don't translate one-to-one.

"fixed stuff" is not a commit message. Paste your diff or describe the change — get a clear commit message your future team will actually thank you for.

Don't pick a stack you'll fight for years. Describe what you're building and your skills — get a real recommendation with trade-offs, not hype.

Find the holes before someone else does. Paste your code — it runs an OWASP-style security review and tells you what an attacker would try first.

"Works on my machine" — famous last words. Describe your app — get a Dockerfile and setup that runs the same everywhere, explained so you understand it.

Naming things is half of programming and you're stuck. Paste the code or describe it — get clear, consistent names that make the code read itself.

Designing an API and want it to not be a regret in six months? Describe what it does — get clean endpoints, naming, and the edge cases you'd forget.

Say what you want in plain English, get clean SQL back — plus the gotchas (nulls, dupes, slow joins) you'd only find in production at 2am.

Paste anything that reads like a robot wrote it. Get it back sounding like a human with an opinion — short sentences, no 'leverage,' no fluff.

About to drop real money and not sure? Tell it the purchase and your situation — get an honest gut-check on whether it's worth it, not just permission.
