TL;DR
- PostMagnet (9.1/10) — voice-matching AI + multi-platform + Kanban + free plan

- $10/mo more buys: voice AI, two extra platforms, real free tier, Kanban
The 30-Second Verdict
If you write LinkedIn posts once a week or less and just want a cheap AI helper — Supergrow at $19/month is fine. If you publish 2+ times a week and care about output quality, voice consistency, or expanding to Twitter/X and Reddit — PostMagnet at $29/month is a much better tool.
The price gap is small. The capability gap is large.
Where PostMagnet Pulls Ahead
1. AI quality — voice matching vs templates
This is the biggest gap. Supergrow's AI relies on prompt templates and viral-post frameworks. Output is fast but generic — most users edit 50–70% before publishing. PostMagnet trains on your past posts; the AI internalizes your phrasing and rhythm so output needs minimal editing. The 24/7 AI chat lets you iterate live ("punchier hook", "shorter", "add a story").
2. Three platforms, one tool
Supergrow is LinkedIn-only. PostMagnet publishes to LinkedIn, Twitter/X, and Reddit from one dashboard. Repurpose threads to LinkedIn carousels or vice versa.
3. Real free plan
Supergrow gives you a time-limited trial. PostMagnet's free plan is permanent — 5 posts/month, basic AI, LinkedIn publishing. Test indefinitely before paying.
4. Visual Kanban pipeline
Supergrow has a calendar; PostMagnet adds a drag-and-drop Kanban (Ideas → In Progress → Ready → Scheduled). For batching content weekly, this is a meaningful workflow boost.
5. Deeper analytics + multi-platform trending
Supergrow's analytics are surface-level and trending is LinkedIn-only. PostMagnet covers LinkedIn + X + Reddit on both fronts.
Where Supergrow Pulls Ahead
1. $19/mo entry tier
Supergrow undercuts PostMagnet Pro by $10/month. For absolute beginners on a tight budget who only need a basic AI helper, that gap matters.
2. Cleaner UI for first-time users
Supergrow's LinkedIn-only focus makes it simpler to navigate at first. PostMagnet has more features, which means a slightly steeper initial learning curve.
The Pricing Cage Match
