# Chronicle (OpenAI Ambient Memory)

## Profile

Reportedly an [[entity-openai-d3]] **ambient memory feature** that backs the persistent context layer for [[entity-codex-d3]]. Implements the broader [[concept-ambient-agent-memory]] pattern.

## How It Works (per speaker)

1. Periodically captures **screenshots** of the user's Mac.
2. Sends those images to OpenAI servers for processing.
3. Writes **local Markdown files** that summarize user activity.
4. Codex pulls from those local Markdown files when the user asks a context-dependent question later.

## Privacy Posture

Server-side processing means Chronicle is currently **unavailable** in:

- European Union
- United Kingdom
- Switzerland

See [[open-question-privacy-laws]] for the unresolved regulatory tension.

## Enrichment Caveat

No OpenAI product publicly named 'Chronicle' is documented. The capability described matches the broader pattern of screen-context memory (Rabbit R1, Limitless Pendant, Microsoft Recall) rather than a confirmed OpenAI SKU.
