Aix training, which is available on a number of platforms, is a course on how to use the internet to help people learn English.
It’s available in a number in the United Kingdom, Canada, Australia and New Zealand.
But the US, where the course is offered as a subscription, is not the only country offering it as an alternative.
According to the American Civil Liberties Union, there are more than 1,000 Aix courses available for free, though most are offered to foreigners in the US.
Students have to pay $99 a month for a year to use Aix, according to the Aix website.
Some people are frustrated with the fee and want to switch to another service, the ACLU said.
In August, the US Supreme Court rejected a lawsuit from the American Humanist Association, which argued that the government cannot force students to use free services for religious reasons.
