Supergrow
A LinkedIn-only writing, carousel and scheduling workspace.
NOT REALLY
why this verdict
Keep paying — Microsoft has not replaced it
Microsoft's version overlaps, but does not finish the social media job, so this one still earns its $19/mo.
- A named launch, not a vibe named, unlinked
- LinkedIn added AI writing prompts inside its own composer. Microsoft, October 1, 2024 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 1 of 3 listed replacements have a usable free tier: ChatGPT.
- What the call is worth $228/yr
- $19/mo at the entry paid tier — $228 a year per seat.

The backstory
Supergrow is narrow on purpose: it only cares about LinkedIn, so it knows the character limits, the carousel format, the hook patterns and the analytics that platform surfaces. LinkedIn's own suggestions write in generic corporate voice, and not sounding like that is the entire point of the product.
