I feel like all SaaS are eventually building a variant of the same things, whether it's email client, CRM, analytics, or AI interface builder now. We end up working with dozens of SaaS with overlapping features that are ever so slightly different and solving just one use case.
"AI" is just a buzzword most of the time. So many companies have literally just added it to their product name, or in to some description of the product. In all likelihood, nothing has really changed other than maybe a thin OpenAI API wrapper doing something nobody asked for.
Also, "AI" in it's majority current form, has been around for decades it's just cool now to use the word "AI" when branding a product/company.
