Use AI features

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

Key features:

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 of one-mark questions.

Please note that this takes some time to complete and attracts premium pricing. We anticipate that costs may reduce as AI models become cheaper and more powerful.

This feature is available when:

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, most schools will not see the AI auto-marking button by default. To access the feature, add /AI to the end of the URL on the marking page.

AI credits

Using AI to automatically mark student work consumes credits. This is necessary due to the underlying model costs.

Your subscription includes 100,000 AI credits as a starting point, shared between all teachers. To purchase more, please email us to request an invoice. The current rate is £10 for 100,000 – a great investment in reducing workload. Credits are non-refundable.

The marking of each one-mark answer currently costs 50 credits. For example, auto-marking a 10-question test for 20 students would consume 10,000 credits. This per-question cost may change over time. Please note that credits are consumed even if the AI output is inaccurate.
