Is there any tools available for description generation?? If yes please share.

Description generated by own is the best way to represent website description.
this may help you for website SEO.

Yes manually create description is good for your website, and no tool available this kind of tool in Google...

You try write description is own because of this your content is already unique & quality content very important for submission.

IN my opinion you should be write a description manualy.

Yes, there is a tool named meta description generator which can help you to generate a description as well as title. But I'll suggest you to write it manually, because your contents and title should be unique.

thank you so much all of you for share your views.

Manually create your website's description , that will be good for your site
