把手机里的对话，搬到更大的输入场景里完成

It is a browser-based companion that mirrors the conversations from the mobile app onto a larger screen. Instead of moving chats to a new account, it reads the same message history from your phone and lets you type, attach files, and search from a desktop keyboard. The phone remains the primary device, so anything you send from the computer still travels through it. Availability and the exact menu names vary by version, so check the current interface or the official help pages for your region.

Historically the phone had to stay online because messages were relayed through it. Recent multi-device improvements let some accounts stay active for a period even when the phone is offline or the battery is drained, but the exact window depends on your app version and account. The safe habit is to keep the phone charged and reachable, then confirm in the settings panel whether linked devices are supported for your setup before relying on it during a long meeting.

Open the mobile app, go into the linked devices area of settings, and you will see every session currently attached to the account with the device name and the time it was last active. From there you can remove a single session or clear them all. If you suspect someone else has access, remove every entry, then change your phone's lock method and re-link only the devices you trust. The menu label differs slightly between platforms.

Sessions expire for several reasons: clearing browser cookies and site data, using private or incognito windows, switching networks, or simply reaching the time limit the service sets for a linked session. When that happens you just re-open the site and scan a fresh code with the phone. To reduce repeats, avoid auto-clearing site data for that domain, stay on a stable connection, and keep the browser updated.

You can drag files straight into a conversation and attach documents, images, and media the same way you do on the phone. The practical limit is not fixed in one place, because it depends on the file type, the recipient's client, and the version you are running. If a transfer fails, split the file into smaller parts, use a cloud link for very large items, and check the current attachment guidelines in the official help center rather than assuming a specific number.

It is workable but requires discipline. Always sign out from the linked devices menu when you finish, never leave the tab open and unattended, and decline the option to stay signed in if the browser offers it. On machines you do not control, avoid opening sensitive conversations, and prefer a private window so that cached data is discarded when you close it. Treat any shared machine as temporary and remove the session afterwards.

Each linked session belongs to one account. To work with two numbers on the same computer, you typically need two separate browser profiles, or one normal window and one private window, and link each one with its own phone. Switching within a single signed-in session is not supported. This keeps the two identities separate, but it also means notifications, unread counts, and history do not merge across the two windows.

Check three things in order. First, make sure the browser has permission to show notifications for that site. Second, confirm that system-level focus or do-not-disturb mode is not blocking them. Third, verify the tab is not muted and that the phone still has the conversation syncing normally. If all three look correct but nothing appears, remove the linked session and link again, then test with a message sent from another contact.

A tablet browser can open it if the site renders the desktop layout, though the experience is closer to a stretched phone view than a purpose-built app. On a second monitor it behaves like any other browser tab, so you can keep it visible while working elsewhere. The main limitation is that video and voice calling support varies across browsers and platforms, so confirm current calling availability before planning around it.

Start with the phone: confirm it has a working connection, then open the app so it can flush the queue. On the computer, refresh the tab once, and if the conversation list is still stale, close the tab completely and re-open it. Persistent problems usually come from an outdated browser or an expired session, so update the browser, clear site data for that domain, and link again with a fresh code. If it continues, report it through the in-app feedback path.

It can, because the phone keeps a link open to relay activity to the desktop, and that link uses radio and background processing. The effect is usually modest when the phone is on a stable network and idles normally, but it grows if you are constantly sending media or if the signal is weak and the radio keeps reconnecting. Charging while you work, keeping screen-on time low, and not running several linked sessions simultaneously all help.
