Use Cortex Chat on a phone or install it
Use Cortex Chat on a phone or install it in Cortex Chat: practical steps, setting explanations, result checks and troubleshooting.
On mobile, workspace sections and conversations use a compact navigation layout. A browser may offer installation when supported; an installed window and browser tab can differ in available controls. Installation does not create a second account or add tool permissions.
Before you start
Appearance, layout, notification sounds and some cached history are device/browser state. The interface explicitly marks a conversation background as This device and distinguishes an account-saved default Sidekick from a cached value. Another participant or device may therefore look different without anything being broken. A cached conversation is useful while reconnecting but does not prove that identity is currently verified or that a new message reached the server. Preserve useful drafts before clearing browser storage. When troubleshooting, distinguish browser permission, local preference, network availability and external service state instead of treating them as one setting.
Step-by-step
- Open Chat in a supported browser and confirm the intended account.
- Use the workspace section controls to choose Sidekicks, people or apps.
- Use the installation offer when available, then verify the launched app still shows the correct identity and conversations.
What the settings mean
| Control or state | Meaning |
|---|---|
| Device preference | A setting whose effect is local to this browser or device. |
| Account preference | A value confirmed as saved to the signed-in account. |
| Cached history | Previously stored conversation content, not a new server result. |
| Browser permission | Microphone, sound or notification authority outside the app switch. |
Check the result
The compact interface or installed app is usable with the same intended account.
If it does not work
An absent install offer can reflect browser support or an existing installation. Do not use installation as a fix for an authentication or Sessions error.
