i just want one tool to handle my whole marketing.. does it exist?

just started my business and honestly im kinda overwhelmed...
im looking for some AI tools or websites that can actually help me build full digital campaigns like making posts (pics or videos) without needing to prompt every single detail and ideally also post them to my socials... i’ve tried a few random tools but they’re either super clunky or just generate one small part (chatgpt doesnt work out for me)
if you know anything that actually works, i’d love to hear 🙏
