Engagement tool vs LinkedIn editor. Different jobs, often paired.

AuthoredUp is a LinkedIn writing studio delivered as a Chrome extension. Its core promise: replace LinkedIn's frustrating native text box with a proper writing environment.

Features that matter

• ✓Rich-text formatting - bold, italic, special characters, bullets that LinkedIn's editor lacks
• ✓Hook library - 200+ proven post-opener templates by category
• ✓Post endings library - 150+ engagement-driving CTAs
• ✓Multi-device preview - see exactly how your post renders on desktop, tablet, and mobile (including the precise “see more” cutoff)
• ✓Readability scoring - Flesch-Kincaid scores
• ✓Drafts and tags - manage post pipelines with status tracking
• ✓Scheduling - plan posts up to 3 months ahead
• ✓Analytics - performance tracking by post type and format

AuthoredUp has 5.0 stars on the Chrome Web Store - among the highest-rated tools in the category. Reviews consistently call it “the best LinkedIn editor available.”

What AuthoredUp is built for

• ✓Rich-text formatting LinkedIn's native editor lacks
• ✓Hook and ending libraries for post templates
• ✓Multi-device preview of your own posts

What AuthoredUp doesn't do (and why you still need Commentify)

• ✗No engagement features at all - zero commenting, zero outbound visibility
• ✗No AI content generation - you write every word yourself
• ✗LinkedIn only, no X, no Reddit
• ✗No trending post discovery, no prospect surfacing
• ✗Requires the Chrome extension

Commentify is an AI-powered engagement tool with four advantages:

1. Aggressive pricing

$19/mo Starter, $39/mo Full. Comparable to AuthoredUp's pricing for a completely 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, X, Reddit.

• ✓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.

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, subreddits, geography) once. The AI finds matching posts on LinkedIn, X, and Reddit, drafts on-voice comments, and publishes them autonomously. Your name shows up in comment sections of relevant posts, driving profile visits and DMs.

AuthoredUp: $19.95/mo Individual, $14.95/mo per user for Business teams (3+ users minimum).

Commentify: $19/mo Starter, $39/mo Full.

A complete content quality + outbound engagement setup for less than Taplio's mid-tier ($65/mo) alone - and dramatically less than Taplio Pro ($199/mo).

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.

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.

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: $39–$59/mo total. Best-in-class on both surfaces.

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 ($19–$39/mo) - best for multi-platform, 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 ~$39–$59/mo, multi-platform engagement coverage.

Use AuthoredUp if you are

• ✓Bottlenecked on the quality of posts you publish
• ✓Writing your own content but struggling with formatting
• ✓Wanting hook libraries and post-ending inspiration
• ✓LinkedIn-only, content-creation-first
• ✓Cost-sensitive ($19.95/mo is excellent value)

Use Commentify if you are

• ✓Bottlenecked on visibility, not content quality
• ✓Wanting outbound commenting across LinkedIn, X, and Reddit
• ✓Running localized sales/prospecting (geo-targeting essential)
• ✓Selling to sophisticated audiences (fine-tuned voice essential)
• ✓Building personal brand or sales pipeline (or both)

Use both if

• ✓You're running serious LinkedIn growth
• ✓Budget can absorb ~$39–$59/mo total
• ✓You want best-in-class on both content and engagement
