Blendin vs Supergrow
blendin.aivs
Supergrow is a cheap, simple LinkedIn post writer with a big template library, and it does that job well. Blendin is a full content studio: an anti-AI writing engine, on-brand visuals built from scratch, long-form Documents, deeper voice training, and four channels. If you only need fast LinkedIn text, Supergrow may be enough. If you want posts that read human and look like your brand, keep reading.
50 credits a month, no card.

Where Blendin pulls ahead
These are the gaps that matter most once you move past quick text posts.
Anti-AI writing that reads human
Blendin runs every draft through a multi-pass engine that rewrites more than 80 common AI tells, from stock openers to robotic cadence. Supergrow generates solid drafts, but without that dedicated cleanup pass you do more editing by hand to strip the AI sheen.
Visuals built from scratch, not picked from a gallery
Set up a Brand Kit once and Blendin renders carousels and 8 image formats from your colors, fonts, and logo. Supergrow's carousel maker is template-based (with Brand Kit support on Pro) plus an infographic and quote-card generator, which is quick but tends to look like everyone else starting from the same templates.
Long-form Documents, not just posts
Blendin produces full LinkedIn Documents (the swipeable PDF-style format), which earn strong reach. Supergrow focuses on shorter posts and template carousels and does not offer Documents.
Multi-channel and Meta-verified
Publish to LinkedIn, Instagram, Facebook, and Threads through official APIs. Blendin is a Meta-verified business, so there is no 25-tester cap on Threads, Instagram, or Facebook. Supergrow is built around LinkedIn.
Voice training grounded on your real posts
Blendin uses Smart Voice Training that draws on your own published posts, recency-based on Free and Creator and semantic top-5/8/12 retrieval on Pro and up. Supergrow's Content DNA also learns your style from your existing posts, so both personalize well; the difference is that Blendin pairs that with its anti-AI cleanup pass and applies the same voice across four channels, not just LinkedIn.
Where Supergrow is strong
Credit where it is due. Supergrow is a solid budget LinkedIn writer, and for some people it is the right call.
Lower entry price
Supergrow's Starter plan is $19 a month ($16 billed annually) per their public pricing, a touch under Blendin's $29 Creator plan. If budget is the only deciding factor, that gap is real and worth weighing.
Content DNA voice and simple workflow
Supergrow's Content DNA learns your writing style from your existing posts, and reviewers find the output genuinely personal. Paired with a small, fast surface area (generate, preview, schedule), it is a quick way to get LinkedIn posts that sound like you.
Post ideas and a calendar plus Kanban
Supergrow surfaces Post Ideas from a daily-updated viral post database and offers a template carousel maker, infographic and quote-card generators, scheduling with both a calendar and a Kanban board, and an auto first-comment. For LinkedIn-only creators there is plenty to work with.
Pricing compared
Both are affordable. Supergrow edges Blendin on the lowest paid tier; Blendin answers with a real free-forever plan and more in every paid plan.

Frequently asked questions
Is Blendin a good Supergrow alternative?
Yes, especially if you want more than fast LinkedIn text posts. Blendin adds a multi-pass anti-AI writing engine, brand visuals generated from scratch, long-form Documents, deeper voice training, and publishing to Instagram, Facebook, and Threads alongside LinkedIn. It also has a free-forever plan with 50 credits a month and no card. Supergrow is a fine budget LinkedIn writer if those extras are not important to you.
How is Blendin's pricing different from Supergrow's?
Per Supergrow's public pricing (May 2026), plans run Starter $19, Pro $39, and Teams $139 a month for 4 accounts, with 20% off billed annually, a 7-day trial, and no permanent free tier. Blendin is free forever with 50 credits a month and no card, then paid plans run Creator $29, Pro $59, Studio $99, and Agency $199 a month, with roughly two months free when billed annually and pricing in USD, EUR, or GBP. Both are affordable; Blendin's main pricing edge is the free-forever plan.
Does Supergrow have an anti-AI writing engine?
Not a dedicated one. Supergrow's Content DNA learns your style from your posts and produces capable, personal-sounding drafts, but Blendin runs an extra multi-pass step that rewrites more than 80 common AI tells so posts read like a person wrote them. With Supergrow you generally do that final cleanup yourself.
Are Blendin's carousels better than Supergrow's?
They work differently. Supergrow offers a template-based carousel maker (with Brand Kit support and an infographic and quote-card generator on its Pro plan), which is quick. Blendin generates carousels of up to 10 slides from scratch using your Brand Kit colors, fonts, and logo, so they look like your brand rather than a shared template. Blendin also makes long-form Documents, which Supergrow does not.
Can Blendin post to channels other than LinkedIn?
Yes. Blendin publishes to LinkedIn, Instagram, Facebook, and Threads through official APIs, and as a Meta-verified business there is no 25-tester cap on the Meta channels. Supergrow is LinkedIn only as of May 2026, so if you only post to LinkedIn that difference may not matter to you.
Is switching from Supergrow to Blendin hard?
No. Start on the free plan, set up your Brand Kit with your colors, fonts, and logo, and let Smart Voice Training learn from your existing posts. Most of your past work lives on LinkedIn already, so there is nothing to export. You can try Blendin alongside Supergrow before you decide to move.
