Text support is still essential
Text is usually the best option when customers need information they can scan, copy or reference precisely.
For example, text works well for:
Account and billing policies
Product requirements
Error-code definitions
Configuration values
Commands and code examples
Security guidance
Short troubleshooting steps

A written answer is easy to search and update. Customers can quickly find a specific term, copy a command or return to one instruction without replaying a video.
The limitation appears when the customer must translate those words into a visual action.
An instruction such as “open the advanced settings and enable the correct permission” may be technically accurate. But if the interface contains several similar menus, the customer may still not know where to click.
