Free TOEFL® Writing Practice Tools Compared

OpenPrep: structured, local, and free

OpenPrep is a free, open-source macOS app for TOEFL® Writing practice. It includes curated prompts, a focused writing workspace, and structured AI feedback that returns an overall score, CEFR level, criterion subscores, improvement points, and phrase-level recommendations. Attempts are saved locally on your Mac, so you can revisit earlier work and watch your scores improve.

Because OpenPrep connects to AI tools you already use — ChatGPT via Codex, Claude Code, OpenCode, or local Ollama — you don’t pay for another AI subscription.

ETS official resources

The official ETS website and TOEFL® practice materials are the best source for understanding the test format. They offer sample prompts and scored responses, but they do not provide ongoing feedback or progress tracking.

Raw ChatGPT or Claude

If you already subscribe to ChatGPT or Claude, you can paste prompts and ask for feedback. The downside is that the feedback is usually conversational and unstructured. You have to craft your own scoring rubric, manage prompts across chat threads, and track progress manually.

How to build a free TOEFL® Writing study routine

  1. Learn the format with official ETS sample questions.
  2. Practice 2–3 prompts per week in a structured tool like OpenPrep.
  3. Review feedback carefully — focus on recurring weaknesses, not just the overall score.
  4. Rewrite one sentence or paragraph from each attempt using the phrase-level suggestions.
  5. Compare attempts monthly to see improvement in organization, grammar, and vocabulary.
