Frequently asked questions

Quick answers — written by humans, not a chatbot.

Does Curve send my text to a server?

No. Every tool on this page runs locally in your browser. Nothing is uploaded, logged, or sent anywhere.

Is the style score the same as an AP grader's?

No — it’s a fast heuristic. AP graders look at argument, evidence, sophistication, and synthesis. We can’t replicate that; we can flag the surface issues that distract from those things.

Why are first-person phrases flagged?

AP synthesis and rhetorical analysis essays argue — they don’t opine. First-person hedges like ‘I think’ weaken the claim. AP Research is the exception (and you should mostly avoid them there too).
