Step 1 of 5 · Generate
Create a function that finds duplicate values in a list.
def find_duplicates(items):
seen = set()
duplicates = []
for item in items:
if item in seen:
duplicates.append(item)
else:
seen.add(item)
return duplicatesSee what you get after signing up
A full coding workspace — not just a chat box. Generate, run, save, and organize your code in one place.
def find_duplicates(items):
seen = set()
dupes = []
for item in items:
if item in seen:
dupes.append(item)
seen.add(item)
return dupes
# Run
>>> find_duplicates([1,2,2,3,3,3])

AI does the work. You stay in control.
CodeForge is built around a developer workflow: generate, verify, repair, run, and improve. The goal is faster engineering without giving up visibility, control, or ownership of your code.
*Capabilities and limits vary by product, plan, and workflow. This comparison describes broad publicly advertised capabilities, not a claim that competitors lack them.
Built for trust
Your source code is sensitive. We treat it that way.
Your code stays yours
Snippets are private by default and protected by row-level security. Only you can see your own work.
No model training on your code
We don't use your snippets to train AI models, and your code is never shared with third parties.
Delete anytime
Remove your account and all associated data permanently whenever you choose.
Secure authentication
Email verification, password reset, and Google sign-in keep your account protected.
