Use AI features
You can use artificial intelligence (AI) to save time and reduce workload.

- Automatically match scanned tests to student names Unlimited
- Generate topic titles when setting up a test Unlimited
- Mark exam questions Requires credits Experimental
AI doesn't always get things right, and it is your responsibility to review output for accuracy and appropriateness.
AI marking
We have experimental support for AI marking.
This feature is available when:
- exam-style marking is enabled;
- a blank copy of the test has been uploaded; and
- you have enough credits.
In ideal conditions, such as multiple-choice questions, we have found AI marking has an accuracy of about 99%. For complex questions or unclear scans, this may be lower. You should not use AI marking for high-stakes tests. Always follow your school's policies.
As this is still experimental, only admin users will see the AI marking button by default. Other users can access the feature by adding /AI to the end of the marking page URL.
AI credits
Using AI to automatically mark student work consumes credits. This is necessary due to the underlying model costs.
Marking each answer has a base cost of 1 credit. For example, auto-marking a 10-question test for 20 students would typically consume 200 credits.
This base cost supports questions up to 1086 pixels in height. Each additional 1086 pixels, or part of that band, adds 1 extra credit, up to a maximum supported height of 4344 pixels. For increased accuracy with extended-writing answers, we also support the ability to transcribe students' answers before marking, which costs an additional 1 credit per answer.
The tariff is subject to change.
