When adult children want to help their parents request a refund, cancel a subscription, or change account settings, they first write down the task and send a co-management invitation. Their parent opens the invitation on their own computer; the agent browses and fills in forms only on that device, while passwords, verification codes, and identity information always remain local. The page visualizes every step: which website is opening, what will be entered, and who must confirm next. The remote family member sees only the necessary progress and page explanations, while the parent can always see the cursor and take over at any time. If the agent encounters an unfamiliar page or a changed flow, it stops and identifies the blocked step rather than guessing what to click. Payments, identity information, account unlinking, and final submission are set as joint-confirmation checkpoints. After the agent explains the outcome about to occur, the parent confirms locally and the assisting family member confirms that the intended goal is correct before the task can continue. When it is complete, both receive the submission receipt, refund reference number, or a list of items that still require the parent to handle personally. The first version focuses on a small number of high-frequency web tasks, starting with renewals, refunds, and appointments. It does not turn a parent’s browser into a remotely controllable screen-sharing session, and it does not store any site credentials.
