This question already has an answer here:

quick question, I am able to create schematics in EAGLE and other online based tools. But for the purpose of creating basic schematics, i.e. no model numbers, with basic stencil component outlines?

I have VISIO but it does not have all the required shapes, such as op-amps, or is it a case that there is no free option available?

Yes, there is a free circuit creating client. In fact, the Electrical Engineering SE has it as well! It is called Circuit Lab! I believe it's free to design a circuit and to run basic simulations but there are advanced features that will require a subscription.
