Taplio, MagicPost, AuthoredUp, Supergrow: which to pick

You need a LinkedIn tool to create or schedule posts, and you're deciding between Taplio, MagicPost, AuthoredUp, and Supergrow. They all do roughly the same thing — except one: predicting whether your post will work before you hit Publish.

In short

→ Taplio: scheduling + AI generation + LinkedIn CRM. The Swiss Army knife of the market. → MagicPost: simple, fast AI generator. A solid entry point for getting started. → AuthoredUp: advanced formatting + personal content library. Niche, useful as a complement. → Supergrow: volume-oriented AI. Produces fast, doesn't analyze performance. → LinkPost: generates, schedules, AND predicts virality before publication. Score on 33 criteria, 300+ factors. The only one with first-party prediction built on real data.

If you just want to generate content, any of these tools will do the job. If you want to understand why some posts work and others don't — there's only one option.

What each of the four tools actually does

Taplio is the most complete on the list. AI generation, editorial calendar, CRM to manage interactions, post inspirations: it's a true all-in-one. It has a real audience and an established reputation. Its blind spot: zero performance prediction before publication. You publish, you wait, you measure after the fact.

MagicPost plays the simplicity card. You describe your idea, it generates a structured post. The interface is clean, the learning curve short. Good for creating content consistently without spending hours on it. Less suited if you want to understand why your posts perform or don't.

AuthoredUp takes a different approach — it focuses on formatting (bullet points, bold text, mobile preview) and on analyzing your past publication library. Useful for polishing presentation and spotting your best historical formats, but it's not a full generator.

Supergrow is an AI generator oriented around volume and speed. It offers templates, post angles, fast generation. No proprietary data on LinkedIn performance, no pre-publication prediction.

Feature-by-feature comparison

| Feature | Taplio | MagicPost | AuthoredUp | Supergrow | LinkPost | |---|---|---|---|---|---| | AI generation | Yes | Yes | No | Yes | Yes | | Scheduling | Yes | Yes | Yes | Yes | Yes | | Post-publication analytics | Basic | No | History | No | Advanced | | Pre-publication prediction | No | No | No | No | Yes (33 criteria) | | Virality score | No | No | No | No | Yes (300+ factors) | | LinkedIn CRM | Yes | No | No | No | No |

None of the four competitors tell you whether your next post will flop before you publish it.

What LinkPost does that the others don't

Our LinkedIn Algorithm Playbook 2026 analyzed 438,413 posts and isolated the factors that separate a post that performs from one that flops. The finding: posts that follow the right rules — hook in the first 200 characters, right format, sufficient length, stacked writing techniques — systematically outperform the median.

LinkPost integrates those rules into a prediction engine: 33 criteria, 300+ factors analyzed per post, before publication. You draft, the score shows where you stand, you fix before publishing.

Over the first 60 days of use, LinkPost users see an average of 1.93× more likes compared to their baseline. 1 in 4 users multiplies their best historical post by 10 or more. This isn't generation — it's prediction.

How to choose based on your situation

You're starting out and just want to create content regularly: MagicPost or Supergrow get the job done. Simple, fast, accessible.

You also want to manage your network and track interactions: Taplio has a real edge with its CRM. Practical if you do heavy social selling.

You care about formatting and want to analyze your post history: AuthoredUp is a good complement to any generator.

You want to understand why certain posts work, and fix them before publishing: LinkPost is the only option with prediction based on proprietary data.
