Chronicle Explainer Video | devrel product update video made with ngram

About the video

This devrel product update video was made with ngram to introduce chronicle, a feature inside codex that uses recent screen context to build smarter memories for ai assistance, available as an opt-in research preview for chatgpt pro subscribers on macos. the video walks through three real scenarios, codex reading a terminal showing astro build errors and identifying the typescript mismatch causing the failure without extra explanation, chronicle filling in missing context across platforms by locating the right google doc and sending a slack message to the right person from a simple prompt, and chronicle learning a user's tools over time, including handling permission dialogs to create a new google drive document from scratch. the video explains that by capturing what is visible on screen and turning it into persistent memory, codex can understand references, locate sources, and anticipate the tools a developer relies on, reducing how often they need to restate context. it points viewers to the developer documentation to learn more and enable the preview.
