How the review loop works
Sparkslingo is one loop, repeated: write, review, compare, understand, practice, track. Each step exists to make the next one honest.
Write
You write in the language you are learning, about something real. The app does not interrupt with a correction while you are still forming the thought, because a review mid-sentence turns writing into a quiz.
Review, then compare
Once the thought is finished, the AI reviews the text. The reviewed version sits beside your original rather than replacing it, and every change is a thing you can open and read about.
Understand
A correction you cannot explain is a correction you will make again. The reason is written in the language you already speak, so the explanation lands even when the example does not yet.
Practice, then track
Any correction can become an exercise, made from your own sentences rather than from a textbook. Recurring mistakes gather into a profile, which is what turns “I keep getting that wrong” into “here is the pattern I keep hitting, and here is what to do about it”.
AI runs only when you ask. Nothing is reviewed in the background; you open a journal and ask for a review, or nothing happens at all.
