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 all 8 image formats from your colors, fonts, and logo on every plan. 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 July 2026.

Native LinkedIn and Meta, on official APIs

Blendin runs on its own official LinkedIn app, approved for the LinkedIn Community Management API, so it is an official LinkedIn API partner, not a browser extension or a resold login. It is also a Verified Meta Tech Provider. Publish to five networks through official partner APIs within each platform's terms: LinkedIn (personal and Company Pages), Instagram, Facebook, Threads, and TikTok. 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 across five networks, not just LinkedIn.

An AI interview that turns your experience into posts

Blendin asks you a few questions, typed or spoken, and refreshes them daily from your own brand and topics. It listens, transcribes, and keeps the substance as durable notes your posts draw on, so your writing carries your real stories and points of view instead of generic filler. It never invents facts. Supergrow has no comparable interview or knowledge base; you feed it sample posts instead.

Multi-layer Insights in one place

Blendin's Insights go beyond post-level stats: post performance, audience growth and demographics, and best-time-to-post, with honest empty states until real data arrives. Instead of checking each network's native analytics separately, you see how your content is doing in one place. Scheduling and Loops, the recurring scheduler, work as a consistency engine with you in the loop, not an autopilot, 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 their public pricing, 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.

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 (July 2026): Starter $19, Pro $39, and Teams $139 a month for 4 accounts, with 20% off 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.
