Monica vs Nova

Monica

• Summarizing web pages, YouTube videos and PDFs
• Using several model families under one subscription

Nova

• Casual users who want several AI models in one mobile app

• People who prefer to pay by the week instead of committing longer

Monica

• The Free plan allows 40 basic-model requests a day and gives only limited trials of image and video generation, ChatPDF and the AI Agent.
• Pro is capped at 5,000 basic and 200 advanced queries a month. Max and Ultra slow to 100 queries a day after 1,600 advanced and 12,000 basic queries in a month.
• Accounts are for personal use only, and Monica says a team subscription has not launched. The prices listed are for annual billing.
• Monica's help center describes an August 2026 transition in which data created since December 29, 2025 was set to be deleted for users in certain regions.

Nova

• Prices are not on the website: the vendor says they are shown in the app, and the US App Store lists the same plan at several price points.
• The vendor's pages do not say where free use stops or which features need a subscription.
• The site lists macOS, but the Mac version is the iPad app: the App Store marks it as not verified for macOS and requires an Apple M1 chip or later.
• Refunds are generally limited to requests made within 3 days of purchase and after fewer than 20 messages.
