Supergrow is probably our closest fight: similar entry price, official LinkedIn API, and a real writing engine rather than a scheduler. The difference is what each one learns from. Supergrow interviews you and builds a voice model of how you write. Helio Posts crawls your company site and builds a brief of what your business does, sells and can prove. Here is the whole picture, including where they are ahead.
| Helio Posts | Supergrow | |
|---|---|---|
| Price | £18 a month, everything included | From $19 a month; carousels and infographics need Pro at $39 |
| Approval workflow | Included: one tap from your inbox | Only on the $139 a month Teams plan (4 accounts included) |
| What it writes from | A crawl of your company site plus a brand brief on what you argue and what must never be claimed | A voice model of you: past posts, AI interview sessions (their PostCast), Content DNA |
| Formats | Post, article and carousel from one brief | Posts; carousel and infographic makers from the Pro tier |
| How it connects | No extension, nothing touches your session; drafts arrive by email | LinkedIn's official API, by their own security statement |
| Publishing today | A finished, approved post you publish in one click; direct publishing waits on the official API access we are applying for | Publishes directly, on all tiers |
Supergrow details checked on their public pages, 28 August 2026. They ship changes without telling us; if a cell has gone stale, tell us and we will fix it. Our column only states what the product does today, including what it does not do yet.
If the product is you, not your company, Supergrow is genuinely good: the interview-to-content loop is a clever way to capture how a person talks, they publish directly to LinkedIn today on every tier, and they are established, with a visible review record. Choose them if you want a personal-brand engine and can live with review-by-dashboard, or do not need review at all.
Supergrow gates review behind its Teams tier, because it treats approval as an agency feature. We think approval is the founder feature: a company page should never post anything a named human did not say yes to, and that yes should take one tap from the inbox, at the base price, not $139 a month.
The full comparison covers schedulers, browser extensions and voice-clone writers in one place, or go straight to vs Postiv, vs Scripe, vs Taplio, vs Hypefury and vs Typefully.
We'll set up a workspace, load your voice, and show you the first week of drafts, for your own company or a client. If the drafts aren't good enough, that is the fastest possible way to find out.
