ChatGPT adds computer activity timeline as vendors push AI agents deeper into daily work apps

What the sources reported

ChatGPT turns macOS activity into a queryable timeline

OpenAI launched Computer History for the ChatGPT macOS app on August 14, 2026, replacing the earlier Chronicle research preview that used screenshots. The new feature records input events — clicks and typing — and stores them unencrypted locally for 48 hours, with a brief visit to OpenAI's servers, then lets users ask natural-language questions about recent work or pick up where they left off. Availability is limited at launch to ChatGPT Pro, Business and Enterprise users, and the publisher warned the format increases exposure to prompt-injection risk compared with a chat-only setup.

Gemini reshapes Google Sheets into interactive mini-apps

Google added a Sheet canvas mode to Google Sheets that turns a spreadsheet into a custom, interactive "mini-app" — described as a "dynamic, read-write layer that sits directly on top of your spreadsheet data." The intent is to navigate large sheets without scrolling columns and rows, with Gemini handling layout and interaction. For knowledge workers buried in shared workbooks, the change reframes the sheet as an app surface rather than a grid, which has implications for how teams structure handoffs and approvals.

AI collaborators move into marketing work management

Adobe made AI Collaborators generally available in Adobe Workfront workflows on August 14, 2026. Inside Workfront, the collaborator acts as a permissioned user that draws context from projects and returns results to the same task for review and approval, so outputs stay visible in the existing work management system rather than vanishing into a chat tool. Adobe is positioning the feature for marketing departments that already use AI across teams but struggle to track where the work is done.

Google Meet, Fireflies.ai extend agents into meetings and email

Coverage of Google Meet on August 14, 2026, pointed to a new capability that sits apart from the video-call experience, signalling that the meeting tool is absorbing more ambient productivity work. On the same day, Fireflies.ai launched Email Assistant on all plans including free, bringing its meeting-aware AI to the inbox. The assistant triages incoming mail, drafts replies and suggests follow-ups using context from both email threads and past meetings with the same people, and Fireflies.ai said 20+ million people use its meeting product.

What changes for the reader

The pattern across the day is consistent: vendors are moving AI out of separate chat windows and into the surfaces where work already lives — spreadsheets, work management, meeting tools, inboxes and the operating system itself. Permissioned, role-aware actions are replacing one-off prompt exchanges, and meeting or screen context is feeding triage and drafting. Readers should expect new governance questions about what an AI agent is allowed to see, do and record, and a near-term need to decide which of these surfaces to enable and which to keep siloed.

Reader follow-ups to watch

- Confirm Computer History availability in your ChatGPT plan tier before enabling it, and review how long local input logs persist. - Pilot Sheet canvas on a non-critical workbook to test the mini-app behaviour before rolling it to shared reporting sheets. - Ask Workfront administrators how AI Collaborator permissions are scoped and where outputs are reviewed. - Try the Fireflies.ai Email Assistant on a single inbox first to gauge how meeting context shapes draft replies.
