PostHero review: how its AI scheduler handled our LinkedIn posts

How we scored it

PostHero's best part was reliability, at 3 out of 5. Features was its weakest at 2, and the other three parts sat at 2.5.

Overall score: 2.5 / 5, the average of the five parts, rounded to the nearest half point.

• Reliability (3/5): Eight of our 12 posts went out on time and in the right format, which was fair but left 4 posts with a problem.
• Ease of use (2.5/5): Scheduling a week of posts took 32 minutes, which is workable but slower than you'd hope for three posts a week.
• Analytics accuracy (2.5/5): Only 19 of 30 analytics figures matched LinkedIn's own numbers, so you can't fully trust its reports.
• Features (2/5): Its client approval step passed only 6 of our 10 checks, and the AI assistant, analytics and voiceover reels aren't on the cheapest plan.
• Value for money (2.5/5): Starter appears to cost $29 a month, a fair price, but its results only put it in the middle of our lineup.

PostHero in plain terms

PostHero is a social media scheduler with AI built in. It writes, schedules and publishes posts across eight networks from one dashboard: LinkedIn, X, Instagram, Threads, Facebook, YouTube, TikTok and Bluesky. It also finds viral posts and reels for ideas, builds carousels and makes faceless reels with an AI voiceover.

What sets it apart is that you can run it from an AI assistant. Connectors and an MCP server let you ask Claude or ChatGPT to draft and schedule posts for you, and it also works with Cursor, Codex and Claude Code. If you'd rather not use AI, a classic scheduling mode works without it.

Because it covers so many networks, PostHero sits between a LinkedIn writing tool and a general scheduler. Our LinkedIn tools hub covers the wider field.

What happens after you sign up

PostHero takes you from ideas to approved posts in four steps.

1. Connect your accounts. Sign in to each network through its own login. PostHero says it never sees your passwords.

2. Research ideas. Find viral posts and reels, and track Instagram competitors and keywords.

3. Create your posts. Write posts in your voice, build carousels and voiceover reels, or ask Claude or ChatGPT to do it for you.

4. Approve and publish. Drafts sit in a calendar, and PostHero says nothing goes live until you approve it.

What you get

PostHero packs a lot in, but several of its AI features start on the Creator plan rather than Starter.

Who gets the most out of PostHero

PostHero makes most sense if you post to several networks and like the idea of asking an AI assistant to handle it. It makes least sense if LinkedIn is your only channel and you need every post to go out perfectly.

PostHero vs AuthoredUp, Taplio and Supergrow

AuthoredUp came first in our test with 3 out of 5. It focuses on formatting and analytics rather than AI writing, and starts at $14.95 a month. EasyGen came second, but it's closed to new sign-ups. See our best LinkedIn tools list for the full ranking.

Taplio scored 2 out of 5 and goes deeper on LinkedIn engagement and outreach, from $39 a month. Supergrow matched PostHero's 2.5 and focuses on an AI writer for LinkedIn, also from $39 a month. PostHero stands out by covering eight networks and AI agents.

Our 28-day PostHero test

We tested PostHero for 28 days, from September 29 to October 26, 2026. Our standard test for LinkedIn content tools is to plan and post the same 12 LinkedIn posts over 4 weeks, then judge the writing, the scheduling and how accurate the analytics are. The full set-up is in how we test.

Scheduling was steady but not quick. It took us 32 minutes to schedule each week of posts. That's manageable for a few posts a week, but it adds up if you post to several networks.

Then we watched what went out. Eight of the 12 posts were published on time and in the right format. The other 4 had a publishing problem. For a scheduler, that's the core job, so one post in three going wrong is a real worry if you rely on it for a client.

We also ran a client approval round, since PostHero keeps drafts in a calendar until you approve them. Its approval process passed 6 of our 10 checks.

Finally, we compared PostHero's analytics with LinkedIn's own figures. Only 19 of 30 numbers matched. If you use its reports to decide what's working, some of what you see won't line up with LinkedIn.

PostHero did a fair job of the basics but left too many loose ends. Eight of 12 posts went out correctly, scheduling took 32 minutes a week, analytics matched LinkedIn in 19 of 30 figures and approvals passed 6 of 10 checks. That's enough for third place, but not enough to leave it unwatched.

Tested September 29, 2026 to October 26, 2026.

The good and the bad from our test

How much PostHero costs

PostHero has three main plans and a standalone API plan, all paid. Its pricing page shows two prices for each plan with a monthly and yearly toggle, but doesn't label which is which. Reading them in the usual way, Starter is $29 a month billed monthly or $19 a month billed yearly, and Creator is $79 a month billed monthly or $49 a month billed yearly. Agency is $199 a month, with no yearly price shown.

Most solo creators would look at Starter or Creator. Starter covers 10 social accounts, scheduling and carousels, but leaves out the AI assistant and voiceover reels. Creator adds those, plus audits and analytics. Yearly billing is advertised as two months free. Prices were checked on November 3, 2026.

There's no free plan, but there's a 7-day free trial on all plans. PostHero doesn't say whether you need a card to start it.

Refund terms conflict. The pricing page promises a 30-day money-back guarantee, while the terms say sales are final except for a guarantee you must request within 14 days, and only if you haven't had a refund in the past 12 months. Ask support which applies before you pay.

Subscriptions renew automatically. To cancel, the terms say to email PostHero support with written notice.

Prices checked November 3, 2026. Prices can change, so check before you buy.

Is PostHero safe to connect to your social accounts?

PostHero connects through each network's own login and says it never sees your passwords. It also says nothing goes live until you approve it, which matters if you let an AI assistant post for you. In our test, its approval process passed 6 of our 10 checks, so don't rely on it blindly.

We couldn't check how PostHero handles your data: its privacy policy page returned an error, and it states no security certifications. Its terms page is dated 2020 and names a company called Jupiter LLC, so it may not match today's product. The terms make you responsible for all activity on your account and don't say who owns AI-generated content.

Keep the approve-before-publish setting on whenever an AI agent posts for you.

What PostHero users say

There's almost no public user feedback on PostHero. We found no Trustpilot page, only one G2 review under its former name, SMM Agent, and nothing on Product Hunt.

That doesn't mean users are unhappy, just that there's too little to judge. For now, our test is the best independent guide to how it performs.

Recent user reviews, in short

Summarised in our own words, not quoted. Reviewer names are left out.

With so little user feedback, our results carry more weight than usual. They show a capable, flexible scheduler that gets most posts out, but whose 4 problem posts and patchy analytics mean you should check its work.
