Frequently Asked Questions
Is my screen data stored on OpenAI servers?
Screen captures are stored temporarily on your device, processed on servers to generate memories, and then deleted from servers after processing unless legally required; memories are stored locally only.
How can I control when Chronicle generates memories?
You can pause or disable Chronicle via the Codex menu bar icon or settings, allowing control during sensitive activities like meetings.
What are the rate limits for Chronicle?
Chronicle consumes rate limits quickly due to its design of running background agents to process screen captures, which may limit usage frequency.
Can I view or edit the memories created by Chronicle?
Yes, memories are stored as unencrypted Markdown files locally, which you can read, modify, or delete to manage information.
Who can use Chronicle and on which platforms?
Chronicle is available as a research preview for Pro subscribers on macOS, requiring Screen Recording and Accessibility permissions.
