The short version
PrepEx is a newer AI-powered prep platform covering TOEFL, IELTS, and PTE, built around short daily drills, a "Petra" AI speaking coach, and a 2026 task-type curriculum. Its genuine strength is the practice-first, high-frequency workflow — small daily reps across all four sections rather than long study sessions, plus a 7-practice warmup path before you sit a full baseline test, which is a reasonable way to build confidence before a scored attempt.
The tradeoff of covering three exams in one product is depth: TOEFL-specific detail can end up sharing space with IELTS and PTE material and pricing. If you're preparing for the TOEFL 2026 format specifically and want a tool built only for that exam, that's a real difference worth weighing.
Where PrepEx genuinely wins
- An AI speaking coach (Petra) aimed specifically at Speaking practice and pronunciation, alongside flashcards and grammar exercises.
- A structured warmup path — a set number of practice drills before you unlock your first full baseline test, which can help build routine for less confident starters.
- A free tier with a daily practice cap, so you can try the product before paying anything.
- Multi-exam coverage if you're still deciding between TOEFL, IELTS, and PTE.
Where TOEFL Exam Prep is built differently
- TOEFL-only, top to bottom. Every task type, rubric, and drill is built for the 2026 TOEFL redesign specifically — nothing shared across other exams.
- Grading tied directly to the published ETS TOEFL rubrics, not a general-purpose scoring model reused across exams.
- Unlimited practice and grading on every paid plan — no daily practice cap to work around.
- Weak-area targeting built on your actual attempt history. After every attempt we identify which specific task types you're scoring worst on and keep fresh, right-leveled sets ready for those — a similar idea to PrepEx's adaptive loops, but driven by your real per-task-type scores rather than a fixed warmup sequence everyone goes through.
- A free instant score estimate with no warmup gate before you see where you'd land.
