AI feedback and grading on the Redação Paraná writing platform
Paraná's school writing platform has AI correct about 153,000 student texts in 2025 and adds new genres in 2026
Problem
Students in Paraná's state schools write millions of texts a year on the platform, and teachers cannot give detailed feedback on all of them.
Approach
Seed-PR works with Google on automatic correction. The AI has corrected argumentative essays since 2025, and in March 2026 it was extended to short stories, chronicles and personal accounts, using new rubrics for each genre. It scores genre fit, idea progression, theme development and language use, then writes feedback for revision.

Takeaway
About 153,000 of more than 4.6 million texts received AI correction in 2025. Three more genres were added in March 2026.
