Explain how the Calvin cycle fixes carbon
54%
Gap found
Said energy becomes glucose “directly” — skipped the G3P intermediate entirely.
01Explainaloud
Know when you actually understand it.
A team of specialist AI agents builds from your sources, listens to you explain the material, and independently checks the steps you skipped.

What a session looks like
A topic, an explanation scored on how well you actually said it, and the exact step you skipped. Keep scrolling to turn the ring.
Organic chemistry
Walk through an SN2 reaction mechanism
71%
Gap found
Got the backside attack right, never mentioned why bulky substrates kill the rate.
Macroeconomics
Why does raising rates slow inflation?
38%
Gap found
Named the mechanism but couldn't connect it to borrowing cost or demand.
Linear algebra
What does an eigenvector actually mean?
82%
Gap found
Strong geometric intuition, shaky on why the eigenvalue can be negative.
Neuroscience
Describe how an action potential propagates
61%
Gap found
Skipped the refractory period, so the explanation allowed backward travel.
Statistics
What is a p-value actually telling you?
45%
Gap found
Described it as the chance the hypothesis is true — that's the inverse.
Computer science
Why is quicksort O(n log n) on average?
76%
Gap found
Explained the partitioning but never justified the log n recursion depth.

03Multi-agent by design
One lesson. Several specialists.
Explainaloud does not ask one model to do everything. Each agent owns a specific job, passes its work forward, and leaves a visible trace so you can see how the result was made.

04Why it works
The illusion of competence
Rereading feels like learning. The material looks familiar, so your brain files it as known. But recognition is not recall, and exams only test recall.
The gaps stay hidden until you explain the idea in your own words. Explainaloud is built around that moment.

Step 2
Say it back, out loud
Hit record and explain the concept like you're teaching a friend. Shaky steps get flagged as you say them.
“Plants convert sunlight into chemical energy.”
“That happens in the chloroplasts.”
“”
Flagged: what do you mean by “directly”?
Step 3

Every topic gets a confidence score from your explanation. Weak areas become tomorrow's study plan.
