One block becomes the next move.
Practice creates evidence. Evidence chooses the repair. Review verifies whether the repair held. That's the whole system — and it compounds.
Take a focused block
10–20 minutes of real evidence — not browsing a giant question bank. Short enough to do daily, long enough to mean something.
10–20 min · ~10 questionsalgₐ reads the evidence
One miss is an early signal. Repeated misses across blocks become a pattern. Coverage and confidence stay visible, so weak evidence never looks certain.
Signal + confidenceRepair the next block
Today gives one dominant next action. You can still build a custom block, but the recommendation stays tied to the strongest available evidence.
One queued blockVerify it held
Missed questions return later under light time pressure. A repair only counts when it survives a second look — that's how the loop closes.
Spaced re-checkThe whole loop, in one question.
Answer it the way a student would. Watch algₐ explain the result without pretending one answer is a permanent diagnosis.
The documentary filmmaker sought a subject that was ______ her own experience yet still resonant with a broad audience, so she chose to chronicle the lives of immigrant families in her hometown.

Honest coaching, not cheerleading.
Sati turns the current evidence into one decision: continue, repair, or review. When the sample is thin, Sati says that directly instead of inventing certainty.
- Separates an early signal from a repeated pattern
- Always a range with confidence — never an official score
- Re-checks the same trap until it holds
“Transitions is the strongest current repair signal: 3 misses across 2 completed blocks. Run the focused block now. If the same trap returns, it stays in Review; if it holds, algₐ lowers the repair pressure.”
Run the loop on your own misses.
Free during beta. The first block creates evidence in about 15 minutes; algₐ Signal unlocks after 40 answers or 3 completed practice sessions.
