Pros & cons
Google Gemini Memory
Pros: Tightest integration of any memory product with personal data sources (Gmail, Drive, Calendar) where users have meaningful history.
Cons: Cross-product data sharing is a trust liability; persistence model has been less clearly communicated than ChatGPT's.
Meta AI Memory
Pros: Native delivery via WhatsApp / Instagram / Messenger reaches billions at the app level.
Cons: Non-developer surface only; no API; cross-product data flow remains a privacy concern.
