Engagement tool vs LinkedIn editor. Different jobs, often paired.
AuthoredUp polishes the posts you write. Commentify drives visibility through commenting on posts others write (and now has its own Post Agent for your own posts too). Many founders use both - pricing combines to $59–$79/mo for a complete content + engagement workflow.

- AuthoredUp ($19.95/mo): LinkedIn writing studio Chrome extension - rich-text editor, 200+ hook library, post preview across devices, analytics, scheduling. LinkedIn-only.
- Commentify ($39–$59/mo): outbound engagement tool - finds high-intent posts on LinkedIn and X (Reddit coming soon), drafts comments in your voice (fine-tuned model), publishes autonomously. Geographic targeting nobody else offers, plus its own LinkedIn Post Agent for your own posts.
- The honest answer: AuthoredUp polishes the posts you write. Commentify drives visibility via commenting on posts others write - though Commentify's Post Agent now covers basic posting too. Many founders still run both - pricing combines to ~$59–$79/mo.

What is Commentify?
Commentify is an AI-powered engagement tool with four advantages:
1. Aggressive pricing
$39/mo Starter, $59/mo Pro. Comparable to AuthoredUp's pricing for a largely different (and complementary) job.
2. Geographic targeting
Filter post discovery by city, region, or country. Critical for sales prospecting and localized brand presence. AuthoredUp doesn't have an engagement layer at all.
3. Fine-tuned voice model
Trained on your past writing, with separate tone profiles.
4. Dual use cases
Personal branding or sales agent - distinct workflows in the same tool.
Multi-platform: LinkedIn and X today, Reddit coming soon.
LinkedIn growth has two distinct motions
- ✓Content motion - publishing posts on your own profile that get reach. Tools: AuthoredUp, Supergrow, Taplio, ContentIn.
- ✓Engagement motion - commenting on other people's posts where your audience already is. Tools: Commentify, PowerIn, Commenter.ai.
These motions complement each other. Founders running serious LinkedIn growth use one tool from each category.
AuthoredUp lives entirely in the content motion. It makes your posts look better, read better, and perform better. It doesn't help you get visibility through engagement.
Commentify lives entirely in the engagement motion. It puts you in front of other people's audiences via comments. It doesn't help you write better posts.
The workflows don't overlap
AuthoredUp: Open LinkedIn, click the AuthoredUp icon, write your post in the rich editor, format it, preview on mobile, schedule for the right time, hit publish. The post lives on your profile.
Commentify: Set targets (keywords, creators, accounts, geography) once. The AI finds matching posts on LinkedIn and X today (Reddit coming soon), drafts on-voice comments, and publishes them autonomously. Your name shows up in comment sections of relevant posts, driving profile visits and DMs.
Comparable, different jobs
AuthoredUp: $19.95/mo Individual, $14.95/mo per user for Business teams (3+ users minimum).
Commentify: $39/mo Starter, $59/mo Pro.
| Setup | Monthly | Capabilities |
|---|---|---|
| AuthoredUp + Commentify Starter | $59 | Post formatting + engagement, LinkedIn or X |
| AuthoredUp + Commentify Pro | $79 | Post formatting + advanced engagement + geo-targeting |
| Taplio Standard (alternative) | $65 | LinkedIn only, no Reddit |
| Taplio Pro (alternative) | $199 | LinkedIn only, full Taplio suite |
The AuthoredUp + Commentify Starter combo at $59/mo is roughly in line with Taplio's mid-tier ($65/mo) alone. Even the higher $79/mo combo is dramatically less than Taplio Pro ($199/mo) - about 60% cheaper.
Commentify-only
AuthoredUp doesn't have an engagement layer at all, so geographic targeting is an apples-to-oranges discussion. But for the engagement workflow most founders need, Commentify supports city/region/country filtering - letting you target only ICPs in your geographic market. No other tool in the category offers this.
Different writing modes, both well-handled
AuthoredUp doesn't write for you - it makes your writing better through formatting, structure, and hook libraries. The voice is yours because you're typing every word.
Commentify trains a fine-tuned model on your writing samples to produce on-voice comments - purpose-built for the comment format (shorter, more conversational than long-form posts). Different writing modes; both well-handled by their respective tools.
Bottleneck-driven decisions
The case for AuthoredUp alone
Some founders genuinely have a content bottleneck rather than an engagement bottleneck. They post inconsistently, their posts feel rough, they don't understand what hooks work. AuthoredUp solves that - and at $19.95/mo, it's excellent value.
If your LinkedIn problem is I don't post enough good content, AuthoredUp alone fixes it.
The case for Commentify alone
Other founders post fine but don't show up anywhere else. They have decent content, low traction, no inbound. The fix isn't better posts - it's more visibility, and visibility comes from showing up in other people's comment sections.
If your LinkedIn problem is nobody sees my profile or DMs me, Commentify alone (or with another content tool) fixes it.
The case for using both
Most founders running serious LinkedIn growth need both motions:
- ✓AuthoredUp polishes the posts you write
- ✓Commentify drives visibility through commenting on others' posts
Combined cost: $59–$79/mo total. Best-in-class on both surfaces.
The 2-tool LinkedIn setup
Content layer - pick one
- ✓AuthoredUp ($19.95/mo) - best for founders who write well and want polish
- ✓Supergrow ($19–$29/mo) - best for founders who want AI to draft posts from voice notes
- ✓Taplio ($39+/mo) - best if you want a viral content database
Engagement layer - pick one
- ✓Commentify ($39–$59/mo) - best for LinkedIn + X engagement, geo-targeting, fine-tuned voice
- ✓PowerIn ($59/mo) - alternative if you don't need Reddit or geo-targeting
- ✓Commenter.ai (free tier + paid) - alternative if you prefer manual posting
For most founders, the strongest stack is AuthoredUp + Commentify - best-in-class on both surfaces, total ~$59–$79/mo, LinkedIn + X engagement coverage (Reddit coming soon).
