Celpip AI vs Official PTE Academic AI Practice

Celpip AI is an independent practice tool for CELPIP-General and CELPIP-General LS that simulates test format and timing. It covers Speaking, Writing, Reading and Listening, each with its own clock. After an answer, it provides an estimated score, a CLB range and four dimension scores; Writing reports also mark sentences with suggested fixes. The site says a full report arrives about five seconds after submission. The maker reports Speaking scores within one band 87% of the time at CLB 3–8 and 43% at CLB 9 and above. For Writing, it reports 95% at CLB 3–8 and provides no upper-band figure. It does not issue official scores and is not affiliated with or endorsed by the named testing and government organizations. The free plan costs nothing and includes three scored sessions for the life of the device, plus free Reading and Listening practice. A listed monthly plan costs $16.99 a month. The service is available on web, iOS and Android.

Official PTE Academic AI Practice is a web-based preparation product for people studying for the PTE Academic exam. It provides practice questions, mock tests, AI scoring and feedback, and a dashboard showing scores by skill and progress across sessions. Questions written by the PTE test development team cover all four skills. Free access includes two diagnostic tests, sample Reading and Listening questions, and sample AI scoring and feedback. Paid access adds 15 full-length mock tests, 20 sectional tests, and more than 1,000 official practice questions. AI scoring estimates results and provides trait-level insights aligned with official PTE scoring traits; an AI Tutor can discuss performance and guide what to practice next. Questions can be repeated during access, but each mock and sectional test allows only one attempt. Paid plans are one-time payments: 29.99 USD for 7 days, 59.99 USD for 1 month, or 89.99 USD for 3 months. Pearson says access ending does not trigger an automatic charge.
