Pick the one that fits you
Choose Mem if…
- You want a cross-platform workspace including the web.
- You’re fine with a cloud account and a subscription.
- You want larger cloud models and team-oriented features.
Choose Driftnote if…
- You want your notes and AI to stay 100% on your device.
- You don’t want an account or a required subscription.
- You’re iOS-first and want one-tap capture of anything, with cited recall.
The real difference
Mem optimizes for cloud AI across platforms — your notes live on its servers so its models can work over them anywhere, including the web. That’s powerful, and it’s the right call if you live across devices and want the biggest models.
Driftnote optimizes for private, on-device recall. The index and the AI run on your iPhone; there’s no account and nothing is collected. You give up web access and raw cloud horsepower in exchange for answers that never leave your phone and a free baseline.
