AuthoredUp vs. Supergrow vs. Authormity: The 2026 Head-to-Head Teardown
Do you need an analytics Chrome extension, a carousel maker, or an inbound revenue engine? We teardown features, workflow speed, visual quality, and pricing.
AuthoredUp vs Supergrow is one of the most searched LinkedIn tool comparisons in 2026, but they solve different problems:
- AuthoredUp: Best for writers who want bold/italic formatting and cohort analytics. Zero AI generation.
- Supergrow: Best for pure AI drafting with interview prompts. No analytics on entry plan, no CRM.
- Authormity: Delivers AI Voice DNA, formatting, analytics, 4:5 carousels, 4-week funnels, and a personal CRM for $29/mo (or $0 free) — saving $30–$40/mo vs running both.
AuthoredUp vs Supergrow is one of the most searched LinkedIn tool comparisons in 2026, and for good reason — they solve two completely different problems. AuthoredUp is a Chrome extension built for formatting and analytics. Supergrow is an AI content engine built for generation and voice cloning.
Comparing them head-to-head only gets you halfway to the real question founders and creators are actually asking:
“Do I need an analytics Chrome extension, a carousel maker, or an inbound revenue engine?”
This teardown answers that directly — core features, a real workflow speed test, a visual quality test, and a full pricing-to-ROI breakdown across all three platforms: AuthoredUp, Supergrow, and Authormity.
Quick Answer: AuthoredUp vs Supergrow in One Line
AuthoredUp is a formatting and analytics layer for people who already write their own posts. Supergrow is an AI writing engine for people who want content generated in their voice. Neither one gives you a carousel studio, a content strategy funnel, and a lead CRM in the same place — which is the specific gap Authormity was built to close.
Core Feature Comparison
AuthoredUp
AuthoredUp installs directly into LinkedIn's native composer and adds what LinkedIn doesn't offer out of the box: unicode bold/italic formatting, line-break control, a hooks library with hundreds of templates, multi-device post previews, and strong per-post analytics with cohort comparisons against your own rolling averages.
Supergrow
Supergrow's core feature is Content DNA — a voice profile built from your past posts or a structured interview, used to generate new posts that sound like you. Its most distinctive capability is a conversational interview mode that turns a short Q&A, or a pasted blog/video/PDF, directly into a batch of ready-to-edit LinkedIn posts.
Authormity
Authormity combines what both of the above do separately — AI generation with genuine mathematical Voice DNA™ matching, plus analytics, plus an Apple-grade 4:5 Carousel Studio, plus a 4-week TOFU→BOFU strategy planner, plus a personal CRM for lead follow-up.
Workflow Speed Test
Here is what the actual day-to-day workflow looks like for a founder posting three times a week:
| Workflow Step | AuthoredUp | Supergrow | Authormity |
|---|---|---|---|
| Idea → First Draft | Manual (you write every word) | ~30–60s (AI generated) | ~30–60s (AI generated, Voice DNA™ calibrated) |
| Formatting for LinkedIn | Built-in, fast (bold/italic/spacing) | Basic plain text | Built-in, instant preview & clean line breaks |
| Hook Strength Check | Hooks library only (no scoring) | Not available | Automatic Hook Virality Score (0–100) + AI rewrite |
| Scheduling & Queue | Included | Included | Included (High-dwell algorithmic slots + auto first comment) |
| Carousel Creation | Not available (requires Canva/Figma) | Pro tier only (~$39–49/mo), basic | Included — Zero-click 4:5 Apple-grade slides |
| Performance Tracking | Strong native analytics & cohorts | Locked behind $39+/mo plan | Included from Creator tier ($12/mo) |
| Comment Lead Follow-up | Not available | Not available | Built-in Personal CRM with daily reminders |
The bottleneck with AuthoredUp is step one — you still have to write everything yourself. The bottleneck with Supergrow is that once the post is live, you're flying blind on the cheaper plan, and there's no next step after publishing. Authormityis the only workflow here that doesn't require switching to a second or third tool to get from idea to a tracked, followed-up lead.
Visual Quality Test: Carousels & Formatting
AuthoredUp'sformatting strength is inside the post body itself — bold, italic, spacing, and line breaks that render correctly in LinkedIn's feed. It does not touch carousels or document posts at all.
Supergrow'scarousel maker exists only on the higher-priced tier (~$39–49/mo), and independent testing has generally described it as basic compared to dedicated design tools — functional, but not something you'd use for a polished executive brand.
Authormity's Carousel Studio auto-generates a full slide deck — title slide, insight slides, and a closing CTA — directly from a topic or long-form idea, rendered in the 4:5 mobile-optimized aspect ratiothat performs best in LinkedIn's document-post format. Since LinkedIn carousels consistently reach several times further than plain text posts, this is not a cosmetic feature — it's a reach multiplier that neither AuthoredUp nor Supergrow's base experience matches.
Direct Pricing & ROI Breakdown
| Platform | Entry Price | What You Actually Get at Entry | Full-Feature Price |
|---|---|---|---|
| AuthoredUp | $19.95 / mo | Formatting + post analytics, ZERO AI generation | $19.95 – $44.85 / mo (team tiers) |
| Supergrow | ~$19 / mo | AI generation, NO analytics, NO carousels | ~$39 – $49 / mo |
| Authormity | $0 / mo (Forever Free) | Voice DNA™, 10 AI posts/mo, scheduling | $29 / mo (Pro Suite: unlimited + CRM + carousels) |
The ROI Math: Pairing vs Single Platform
Run the ROI math honestly: to replicate what Authormity's $29/month Pro Suite includes, a founder using AuthoredUp + Supergrow would need AuthoredUp's $19.95 plan for analytics and formatting plus Supergrow's $39–49 plan for generation and carousels — landing at roughly $59–$69/month combined, and still missing a CRM and a content strategy planner entirely.
Authormity delivers the same job-to-be-done for less than half that cost, with lead tracking neither competitor offers at any price.

Final Verdict
AuthoredUp wins if formatting and analytics are the only gap in an existing writing workflow. Supergrow wins if the only need is AI-generated posts in a cloned voice, and analytics can wait.
Neither wins if the actual goal is a complete system — content that sounds authentic, visuals that get real reach, a strategy that removes the blank page, and a pipeline that turns engagement into pipeline.
That combination is why founders comparing AuthoredUp vs Supergrow keep landing on a third option instead: Authormity, at a fraction of the combined cost of running two separate tools.

FAQ: LinkedIn AI Tools for Founders
It depends on the job. AuthoredUp is better for formatting and analytics on posts you write yourself. Supergrow is better for AI-generated content in a cloned voice. They solve different problems rather than competing directly.
