Supergrow vs AuthoredUp
Supergrow is an AI writer that drafts and schedules your LinkedIn posts. AuthoredUp is a formatter and analytics tool for the posts you write yourself. They solve opposite halves of the same workflow.
The short answer
Pick Supergrow if you want AI to write and schedule for you ($19/mo). Pick AuthoredUp if you write your own posts and want best-in-class formatting and analytics ($13.99/mo). Neither does the other job well, so people often pair them. A single app like FeedBoss covers AI drafting, formatting, scheduling, and analytics together at $29/mo.
Pick Supergrow if…
- You want AI to draft posts in your voice
- You want scheduling built into the same tool

- Writing speed matters more than formatting depth
Pick AuthoredUp if…
- You write all your own copy by hand

Where Supergrow wins
Supergrow is built to get a voice-matched draft out fast and schedule it. It clones your tone from past posts, drafts in seconds, and supports multiple workspaces and approvals for small teams. AuthoredUp has no AI writing at all, so if generating content is your bottleneck, Supergrow does work AuthoredUp cannot touch.
Where AuthoredUp wins
AuthoredUp is the gold standard for formatting and measurement. Its live preview is the most faithful on the market, its formatter handles bold, italic, lists, and clean line breaks, and its post-level analytics are best in class. At $13.99/mo it is also the cheapest of the three. For creators who write their own copy and care how it looks and performs, nothing here beats it.
Why they pair instead of compete
Supergrow handles the writing; AuthoredUp handles the polish and the data. A common workflow is to draft in Supergrow, paste into AuthoredUp to format and preview, publish, then check AuthoredUp analytics afterward. It works, but it is two tools and a copy-paste loop. Neither builds carousels or branded graphics, and neither has a structured engagement layer.
The honest take
For AI writing on a budget, Supergrow. For formatting and analytics, AuthoredUp. If running both feels like overhead, FeedBoss combines AI drafting, a rich formatter, scheduling, and analytics in one app at $29/mo, with carousels, branded graphics, and a lifetime plan on top. Compare directly: FeedBoss vs Supergrow and FeedBoss vs AuthoredUp.
