Portable user context API

Develop a personalization service that safely shares user preferences between apps. For privacy-conscious users tired of retraining every AI service.

Why now

As AI personalization spreads, users need control over how their data is shared across services.

Who for
Privacy-focused AI users
Business model
API fees
Effort
A few months

Every new AI app starts from scratch learning user preferences, wasting time and exposing data.

Build a secure profile service where users control what personal context to share. Standardize interfaces for common preference types.

Monetize through developer API fees. Offer premium user features like data brokers.

Start with basic interest/preference storage. Integrate with popular frameworks.

Risk: Requires critical mass of integrations to be valuable.
