Can I use Notion AI without a Notion workspace?
No. Notion AI is exclusively an add-on to Notion workspaces and cannot be used independently. You must first have an active Notion account (minimum $8/month for Plus plan) before adding Notion AI ($8/month). Mem, by contrast, is a standalone application requiring no other subscriptions.
Mem has significantly better mobile support with full AI capabilities on both iOS and Android apps. Notion AI's mobile app exists but has limited AI features—most AI tasks are best performed on desktop. Mem is specifically designed as a mobile-first AI note-taking solution.
Does either solution automatically organize my notes?
Mem automatically tags and organizes notes using AI algorithms, requiring minimal manual effort. Notion AI requires you to manually structure your workspace, though it can help write and enhance content within that structure. If automatic organization is crucial, Mem is the better choice.
How does each integrate with other tools I use?
Notion AI is confined to the Notion ecosystem but integrates deeply with all Notion features. Mem offers broader integrations including browser extension, Slack, email capture, and mobile apps, making it easier to capture notes from multiple sources. For multi-tool workflows, Mem is more versatile.
Notion AI costs $8/month as an add-on, but requires a base Notion subscription ($8-16/month), totaling $16-24/month. Mem costs $10/month standalone with no additional requirements, making it roughly 40% cheaper for users not already committed to Notion. However, for existing Notion users, Notion AI is the cheaper add-on.
