My verdict: the focused tool for LinkedIn writing.
MagicPost does one thing and does it well: help you write LinkedIn posts. Simple, without distractions. It's a good tool, very focused on a single topic (LinkedIn writing) and it does it well.
It's practical for inspiration or structuring posts. I don't personally use it daily, but for those looking for specific help with LinkedIn writing, it's a solid option.
What I like less: the fact that you can do the same thing with ChatGPT and some good prompts. And if you want a complete suite (scheduling, analytics, etc.), Taplio is more comprehensive.
My advice: if you post regularly on LinkedIn and often have writer's block, MagicPost can unblock you. But first try ChatGPT + free templates. If that's not enough, MagicPost is a solid and simple option.
