Comparison
Kadenza compared with Supergrow
Prices and features checked on September 24, 2026.
Where Supergrow wins
Supergrow costs a lot less, from $19 a month, or $16 a month if you pay for the year. It also has Postcast, where you talk an idea through out loud and it turns that chat into written posts, and it can turn your YouTube videos, articles and PDFs into LinkedIn posts.
Pick that instead if You only post on LinkedIn, you think better out loud than in front of a blank page, and price matters more to you than anything else right now.
Supergrow is a LinkedIn writing and scheduling tool. It learns how you write through what it calls Content DNA, lets you plan posts on a calendar or a board, and can add your first comment when the post goes out.
Where it's strong
Talking your posts out is a good idea if writing is the hard part for you. Its Engage feature lets you build feeds of the people you care about, like prospects or peers, so you can comment on their posts without scrolling your whole feed. On its Pro plan it connects to Claude and ChatGPT too.
Where Kadenza fits
Kadenza covers LinkedIn, Instagram and YouTube. You tell it who's ahead of you in your space and it shows you which of their posts beat their own usual, and your guides turn the people who want them into names and emails in the tool you already use.
The honest trade
Supergrow is the cheaper way to write and post on LinkedIn, and for plenty of people that's enough. Kadenza is $117 a month or $840 a year, and what you're paying for is the research and the leads sitting next to your calendar, across three platforms. It's all laid out in the pricing section.
