Head to head
Supergrow vs AuthoredUp (2026): write it for me, or help me finish it?
Supergrow drafts LinkedIn posts in your voice; AuthoredUp is the best editor and analytics tool for posts you write yourself. Pricing, features and which to pick.
Short answer
Pick Supergrow ($39/mo) if starting the post is the hard part: it interviews you by voice and drafts in your style, with carousels. Pick AuthoredUp ($19.95/mo) if you write your own posts and want the best formatting, an exact 'see more' preview and deep analytics with full history import. AuthoredUp makes no visuals; Supergrow's analytics are light.
These two solve opposite ends of the same problem. Supergrow gets words onto the page. AuthoredUp makes the words you've written look right and tells you how they did.
