Is there any way I can see my kids text on my computer?

If there kids you can monitor what/who/when and where.

If your question is about locating where on the computer I can move your question to the computer section where someone with that knowledge may be able to help.

Texting ? On cell phone ? On computer ? Where ?

Do you own and pay for the equipment ? You can do anything you want, if you wish to buy the right equipment and pay enough money for the service
