OpenPrep vs Magoosh for TOEFL® Writing

Magoosh is one of the most recognized names in TOEFL® prep, but it is not the only option. If Writing is the only section you need to improve, OpenPrep is a free, open-source alternative that delivers structured AI feedback without a monthly subscription.

When Magoosh makes sense

Magoosh is a strong choice if you need a full TOEFL® course covering Reading, Listening, Speaking, and Writing, with video lessons, practice questions, and a structured study schedule. If you have several months to study and want all sections in one place, the subscription can be worth it.

When OpenPrep is the better fit

OpenPrep is built for a specific learner: someone who already feels comfortable with most TOEFL® sections but needs focused Writing practice. If you already pay for ChatGPT, Claude, or another AI tool, OpenPrep turns that subscription into a structured TOEFL® Writing coach at no extra cost.

Key advantages:

• No paywall. Every feature is free and open source.
• Writing-first design. No unused Reading, Listening, or Speaking modules.
• Structured feedback. Scores, CEFR levels, criterion notes, and phrase-level suggestions in one clean view.
• Local-first. Your essays and attempts stay on your Mac.
• Open source. MIT licensed; anyone can inspect, contribute, or fork the project.

Cost reality check

A paid TOEFL® prep subscription adds up over a three-month study period. OpenPrep costs $0. The only requirement is a supported local AI tool, which many learners already have.

Which should you choose?

Choose Magoosh if you want an all-in-one course and are willing to pay for it. Choose OpenPrep if you want free, focused Writing practice with structured AI feedback and the ability to track your own progress locally.
