Attn Product Managers - versioned product documentation

Hi PMs What methods and tools do you use to document your product copy, details and features for ready-use by legal (review and sign-off), marketing, website content, customer service, press releases etc? Are there purpose-build software you use, or do you use traditional word processors (Google Docs, Microsoft Word, etc) to type out your draft/final product copies - then share them with relevant stakeholders for review or use? Where they are submitted for review, assume they also use same word processors to mark-up suggestions and corrections. Where you have product updates or revisions, do you then use the same processes for your copies as per your initial version?
