• Advanced and reasoning AI models are reserved for the Unlimited plan.
• The site lists a web app, a Chrome extension and a Word add-in; it mentions no mobile or desktop apps.

SciSpace

• The limits of the free tier could not be confirmed on a SciSpace page.
• Paid plans meter usage in monthly credits: 1,200 on Premium, 10,000 on Advanced and 40,000 or more on Max.
