Code review practice
Would you approve this AI-generated code?
Practice on a code change with three planted bugs. Explain what could break, then get a score and feedback on what you caught and missed.

Example review
“The lookup no longer normalizes email casing. A stored address like Ana@example.com will not match ana@example.com; normalize the key before lookup.”
ReviewIQ result · example
6.0/10
1 of 2 issues caught
Caught · email normalization
You identified that differently cased addresses can miss the stored account.
Missed · save failure reported as success
The new code ignores the save result, then returns True. Check persistence before telling the caller deactivation succeeded.
Feedback: You explained the impact clearly. Next, trace the failure path after each state change.
Illustrative example. Actual scores and feedback vary by review.

Why review practice matters
Would you catch the bug before approving the code?
When you use AI to write code, you still have to decide whether it works. ReviewIQ gives you practice making that call: inspect a change, find three planted bugs, and explain what could break.
Get feedback on the bugs you caught and the ones you missed. Use your next review to put that feedback into practice.
How it works
Practice catching failures before code is approved.
02
Review the change
Read the code and explain the bugs and their impact in your review.
