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 post-idea database

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, per its public pricing, 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, per its public pricing as of July 2026, does not offer Documents.

Multi-network and Meta-verified

Publish to five networks through official APIs: LinkedIn (personal and Company Pages), Instagram, Facebook, Threads, and TikTok. Blendin is a Meta-verified business. Supergrow is built around LinkedIn.

Voice training that learns as you publish

Blendin's Smart Voice Training 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 use it. It is recency-based on Free and Creator and uses semantic top-5/8/12 retrieval on Pro and up. Supergrow's Content DNA, per its public site, learns from sample posts you add. Both personalize well; the difference is that Blendin pairs voice with its anti-AI cleanup pass and applies it across five networks, not just LinkedIn.

Multi-layer Insights in one place

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

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.

Post ideas and a calendar plus Kanban

Based on its public site, Supergrow surfaces Post Ideas from a viral post database and offers a template carousel maker, infographic and quote-card generators, 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. There is a 7-day free trial but no free-forever tier.

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