Questions about plans and credits

What happens after the 14 free days?
You choose Pro or Max and it is yours for 14 days, with no payment details. You can move up or down between them at any time and the days carry over. When they end, the account returns to Free unless you subscribe; nothing you kept is lost.
What are credits?
Check AI, Check plagiarism and Theoretics QA cost money every time they run, so they run on credits. Pro includes 240 a month and Max 720. What a check will use is shown before it runs, a check that fails uses nothing, and the same text checked again within a day uses nothing. Everything else in a plan has no limit.
Do credits run out?
The credits a plan includes start again each month and do not carry over. Credits you buy never run out, and they are used only when the month’s included credits are gone.
What is free, exactly?
On this site, with no account: finding sources, citing them in six styles, verifying a reference list, and reading your assignment’s instructions into a checklist. With a free account: your reading list, reference lists with tags, My Books, your team, and three whole-paper checks a month.
How does an institution buy it?
By a call with us. An Institution licence covers every student of a programme, school or library, with custom integration, white label and one invoice.
