Free play starts with five hearts, replenished one every 90 minutes; free Writing and Speaking practice covers the first five stages of each level. The Free plan is free.

Cambridge Play is intended for learners aged 16 and over and identifies itself as independent of Cambridge University Press and Assessment.

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.
