A project often begins in the browser but rarely stays there. Research pages may feed a document, spreadsheet, design file, or code editor. The useful boundary is therefore not “everything in Chrome.” It is the set of windows you need to complete one outcome.
Decide what belongs inside the browser
Keep pages in one tab group when you normally consume them one at a time and they share the same browser profile. Give the group a specific project name. Close reference pages that have already yielded their information, and bookmark durable references rather than keeping them open forever.
Create a separate browser window when those pages must remain visible beside another app, when two web contexts need to be compared at once, or when the project needs a recognizable system-level window. Chrome can move selected tabs into another window; Safari profiles and tab groups provide different browser-internal boundaries.
Build a cross-app project map
List the smallest active set: one browser window, the draft or source document, and the app that produces the result. Put supporting windows behind that core set. Use the same short project phrase in document names, browser window names where supported, and tasks. The repeated clue makes the set recognizable without requiring every app to share data.
Wallo can associate existing macOS windows with a goal and its tasks. It does not inspect individual tabs or synchronize browser groups, so reassess the assignment if one browser window is reused for a different project.
Close the loop
At the end of a session, save durable links, close disposable tabs, and write the next action. Keep the browser window open only when its live state is part of that action. This prevents an old project window from becoming an unlabeled container for unrelated browsing.
