Description

Redação Paraná is a writing platform launched in 2021 by the Paraná State Education Department (Seed-PR) for students in the state school network. According to CONSED, it has more than 833,000 active users, and in 2025 more than 4.6 million essays were completed on it.
AI correction, developed with Google, was first applied to argumentative essays (dissertativo-argumentativo) in 2025 and has been extended to short story, chronicle and narrative genres. Reported criteria include fit to genre, organisation and progression of ideas, theme development, and language use. Approximately 153,000 texts were AI-corrected in 2025. Teachers remain responsible for discursive and subjective aspects; an academic article in Texto Livre analyses this division of correction between AI and teacher.
Evidence caveat: published figures are usage counts and an anecdotal teacher time saving (about five minutes per essay versus seconds). No controlled evaluation of the Paraná platform was found. A randomised trial of a comparable AI essay-feedback system in Espírito Santo (J-PAL) found +0.09 SD in essay scores, which suggests but does not demonstrate similar effects here.
