Best AuthoredUp Alternative in 2026: Why Castifai Does What AuthoredUp Can't
Quick answer: AuthoredUp formats LinkedIn posts but doesn't create them. Castifai generates LinkedIn posts with optional AI infographics from videos and web content — at $10/month vs AuthoredUp's $19.95/month. If your bottleneck is creating content (not formatting it), Castifai is the better tool.
AuthoredUp has earned a loyal following among LinkedIn creators. With over 2,000 companies trusting it, it's one of the most popular LinkedIn formatting tools on the market. It makes your posts look better, gives you readability scores, and lets you preview how content will appear across devices.
But here's the thing: AuthoredUp doesn't create content. It helps you format and polish posts you've already written. If your biggest challenge is figuring out what to post — not how to format it — AuthoredUp solves the wrong problem.
What Is AuthoredUp?
AuthoredUp is a Chrome extension that enhances LinkedIn's native post editor. It adds text formatting options (bold, italic, special characters), multi-device post previews, a hooks and CTA library, readability scoring, post scheduling, templates, and analytics for tracking your post performance.
It's priced at $19.95/month for individuals or $14.95/profile for teams (minimum 3 profiles). A 14-day free trial is available.
Where AuthoredUp Falls Short
No AI Content Generation
This is the most significant limitation. AuthoredUp has no AI writing capability whatsoever. You still need to write every single post yourself — or use an external tool like ChatGPT and then paste the text in. For professionals who struggle to find time for content creation, this is a dealbreaker.
You Still Need Ideas
AuthoredUp offers a hooks library and templates to help structure posts, but the core insight — the thing worth posting about — still has to come from you. If your challenge is "I don't know what to write about this week," AuthoredUp doesn't help.
Chrome Extension Dependency
AuthoredUp only works as a Chrome browser extension. No mobile app, no standalone web app. In a world where content creation increasingly happens on mobile, this is a real constraint.
LinkedIn Only
AuthoredUp works exclusively on LinkedIn. If you want to repurpose insights into blog articles, infographics, or content for other platforms, you need separate tools entirely.
Why Castifai Is the Best AuthoredUp Alternative
Castifai Creates Content. AuthoredUp Formats It.
This is the core difference. Paste a link to a YouTube video, podcast, TikTok, Instagram Reel, or web article into Castifai, and you get a ready-to-publish LinkedIn post, long-form article, summary, or infographic. The content is generated from real source material — not from a blank page.
Your Video Consumption Becomes Your Content Pipeline
Most professionals watch hours of podcasts, conference talks, and interviews every week. With AuthoredUp, those insights stay in your head unless you manually write about them. With Castifai, you paste the link and get a publishable post in minutes.
AI Infographics — Something No Formatting Tool Can Do
Castifai generates AI-powered visual infographics from video content. Choose from 9 styles — Modern, Editorial, Comic, Blueprint, Data-Viz, and more. This isn't formatting an existing image; it's creating entirely new visual content from a video's insights.
No Chrome Extension Required
Castifai is a full web application. Works on any browser, any device. No extension installation, no Chrome dependency.

Castifai at $10/month gives you AI content generation, infographics, a humanizer, translation, and scheduling. AuthoredUp at $19.95/month gives you formatting, previews, and analytics — but no content generation. You're paying nearly double for a tool that does less of the heavy lifting.
Can You Use Both?
Yes — and some creators might want to. Castifai generates the content from your video sources, and AuthoredUp helps you fine-tune the formatting before publishing. They're complementary tools.
But if you're choosing one, the question is: what's your bigger bottleneck? If it's "I don't have time to create content from scratch," Castifai solves that. If it's "I write great content but need better formatting tools," AuthoredUp is your pick.
Who Should Choose Castifai Over AuthoredUp?
Choose Castifai if you:
- Struggle to find time or ideas for LinkedIn content

Choose AuthoredUp if you:
- Already write all your own content and just need better formatting
- Want detailed readability scoring and multi-device previews
- Need a hooks and CTA library for post structure
- Want LinkedIn-specific analytics for post performance
- Prefer enhancing LinkedIn's native editor rather than using a separate app
