Blendin vs Supergrow

Choose Supergrow if you want to:

• Spend as little as possible to write LinkedIn posts
• Keep the tool simple with a short learning curve
• Use Content DNA to match your writing style
• Stay focused on LinkedIn and nothing else
• Use a template carousel maker and content templates

Anti-AI writing that reads human

Blendin runs every draft through a multi-pass engine that rewrites dozens of 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, from Starter up, all 6 image formats from your colors, fonts, and logo. Supergrow's carousel maker, per its public pricing, is template-based (Pro tier) plus an infographic 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 and Presentations (the swipeable PDF-style format), which earn strong reach. Supergrow focuses on shorter posts and template carousels; its Pro carousel maker exports multi-slide LinkedIn PDF documents, but it does not offer a separate long-form Documents or Presentations format the way Blendin does, per its public pricing as of September 2026.

Native LinkedIn and Meta, on official APIs

Blendin runs on its own official LinkedIn app, approved for the LinkedIn Community Management API, not a browser extension or a resold login. It is also a Verified Meta Tech Provider. Publish through official partner APIs within each platform's terms to LinkedIn (personal profiles and Company Pages), Instagram, Facebook, and Threads, with TikTok on Pro and Business. Supergrow is built around LinkedIn.

Voice Signature that learns from your own posts

Blendin's Voice Signature learns from the posts you publish with Blendin, including the final version you edited by hand, so the writing sounds more like you the more you post. It goes deeper on higher tiers, up to the deepest Voice Signature on Business. Supergrow's Content DNA, per its public site, is taught from sample posts you paste in. Both personalize, but Blendin keeps learning from your real published history and pairs it with the anti-AI cleanup pass on every network it publishes to, not just LinkedIn.

An AI interview that turns your experience into posts

Supergrow has a real interviewer of its own, Postcast, and it is good: an adaptive conversation that hands you 3 to 5 drafts. The difference is what happens to your answers afterwards. Blendin keeps them as durable notes, and every later post can draw on them, so the store of what you know keeps growing instead of being spent on one batch. Fresh questions arrive daily, grounded in your own brand and topics, and it never invents facts.

Post and audience Insights in one place

Blendin reads three things and shows them together: post performance for every post you published through Blendin, audience growth and demographics where the network supplies them, and the best time to post as a day by hour grid. On LinkedIn that means follower growth and reach for a Company Page, and no demographics yet. Every number is real partner data, and a number that has not arrived yet says so rather than showing a zero. Instead of checking each network's native analytics separately, you read it in one place. Scheduling and Loops, the recurring scheduler, work as a consistency engine with you in the loop, and everything runs through official APIs within each platform's terms.

Lower entry price

Supergrow's Starter plan is $19 a month, $16 billed annually, per supergrow.ai/pricing (September 2026), well under Blendin's $59 Starter plan. If budget is the only deciding factor, that gap is real and worth weighing.

Content DNA voice and simple workflow

Per its public site, Supergrow's Content DNA learns your writing style from sample posts you add, and the output can feel 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.

Postcast, a genuinely good AI interview

Per supergrow.ai (September 2026), Postcast runs a 10 to 15 minute conversation with an AI interviewer that adapts its follow-ups to what you say, and produces 3 to 5 post drafts from the one session. Two sessions are included on Starter and more on Pro. If a talked-through interview is how you like to work, this is a strong feature at $19 a month and it is fair to say so.

Templates, repurposing, and a calendar plus Kanban

Based on its public site, Supergrow offers content templates and repurposing, a template carousel maker and infographic generator (Pro), and scheduling with both a calendar and a Kanban board. For LinkedIn-only creators there is plenty to work with.

$19/mo and up

Per Supergrow's public pricing (September 2026): Starter $19, Pro $39, and Teams $139 a month for 4 accounts, or $16, $31 and $133 a month billed annually, and a 7-day free trial.

A lower entry price for a focused LinkedIn writer, if the deeper features and extra networks are not a priority for you.
