Already on Basic? Move up to Premium or Business with a one-time payment. After checkout a new license key is emailed to you — activate it and your account switches to the higher tier, including its full credit allowance.
How it works: pay once → a new license key of the higher tier is emailed to you → activate it in PapersGPT and the upgrade takes effect immediately.
Your existing license keeps working until the new one is activated; unused credits are not lost. Need help? awadb.vincent@gmail.com
