What it's for

Reach for this when you want fast, encouraging feedback on student writing without building a grading rubric from scratch. It's a good starting point for a homework-helper or draft-review feature — one call in, corrections and a next-step tip out.

How to use

Send the student's essay text as `essay` to the endpoint. The pipeline returns a list of concrete corrections plus a single actionable tip for their next draft — designed for a fast inline review, not a full rubric-graded report. Best on short pieces (a paragraph to a page).
