Cost Effective Legal Tools/ Support (I will not promote)

Founder here. Can anyone recommend a legal AI tool to assist with drafting and evaluating basic commercial agreements (eg, NDAs, SAAS agreements)? We had outside counsel draft our standard form agreements, but sometimes we need to tweak these to address specific counterparty edits— and always going to outside counsel is prohibitive. Alternatively, if you know a cost effective human lawyer to handle these basic agreements, that would be helpful too. Thank you.
