SparkVox vs AuthoredUp
Browser extension that enhances LinkedIn writing with analytics
Bottom line
AuthoredUp enhances LinkedIn posting inside the platform - drafting, months-ahead scheduling, and analytics reviewers call seamless (Chrome Web Store ~4.8/5 across 67 ratings in 2026 roundups).
It does not generate content from recordings. SparkVox creates up to 15 LinkedIn drafts per recording, uses Post Analytics to shape future projects, and includes smart schedule pre-fill in the native scheduler.

Read the full overview
SparkVox turns one recording into up to 15 LinkedIn posts, grouped by theme in your project's LinkedIn content strategy - so your feed shows the authority you already have.
AuthoredUp and SparkVox operate at different stages of the LinkedIn workflow. AuthoredUp is a browser extension that feels like a natural part of LinkedIn - reviewers use it to draft posts, schedule content months ahead, and track performance over time without leaving the feed. SparkVox operates at the step before: generating posts from your recordings so you arrive at LinkedIn with a finished draft to polish, schedule, or publish.
SparkVoxSparkVox repurposes podcasts, videos, and transcripts into publish-ready LinkedIn posts in your voice. Create a project in the web app, review theme-grouped drafts in your project's LinkedIn content strategy, and publish to LinkedIn. No writing required.
AuthoredUpAuthoredUp is a browser extension that integrates directly into LinkedIn's composer. Reviewers praise how seamlessly it fits the platform - drafting, scheduling months ahead, and tracking results in one place. It adds formatting shortcuts, post templates, a post library, and in-composer analytics. It is explicitly not an AI writer: you still create the content. A common reviewer wish is smarter recommendations on what to post based on what has worked before.

What AuthoredUp users actually say.
Sourced from public reviews on G2, Trustpilot, Capterra and others.
Pros
- Chrome Web Store rating verified directly at 4.7/5 across 69 ratings
- Formatting and live multi-device preview - showing exactly where LinkedIn's 'see more' cutoff lands - is the most consistently cited strength across reviews
- Product Hunt launch comments praise the preview concept specifically for solving a real LinkedIn blind spot
Show 2 more
- Named endorsement from Richard van der Blom, founder of LinkedIn algorithm research firm Just Connecting
- Analytics beyond LinkedIn's native numbers (saves, engagement rate, growth timeline) cited as the reason users stay subscribed once the formatting novelty wears off
Cons
- Third-party review presence is genuinely thin - Trustpilot shows just one review (3.2/5, Mar 2025) reporting that formatting was lost after copy-pasting into LinkedIn's composer, and no populated G2 or Capterra listing could be confirmed
- No AI content generation - a deliberate positioning choice, but a real limitation for users who also want drafting help
- A cited reviewer wanted content suggestions based on what's worked before - the same gap noted elsewhere on this page
Show 2 more
- LinkedIn-only - no support for other platforms, a limitation for creators repurposing across channels
- Widely-repeated '4.8/5 across 400+ reviews' figures circulating on comparison blogs don't check out against primary review sites - treat large-sample claims about AuthoredUp skeptically

Inside AuthoredUp: key features.
A closer look at what AuthoredUp actually does, based on public reviews and documentation.
Post editor and multi-device preview
AuthoredUp's core feature is a rich-text editor for LinkedIn's composer that adds bold, italic, and bullet formatting LinkedIn's native box doesn't support, then renders a live preview of exactly how the post will look on desktop, tablet, and mobile - including where LinkedIn's 'see more' truncation falls, which determines whether a hook lands. Reviewers consistently describe this as the standout feature in the category. At least one Trustpilot reviewer reports the formatting occasionally failing to survive the copy-paste into LinkedIn's actual composer, which would undercut the feature's core promise.
Content calendar and scheduling
A newer addition - scheduling used to be a notable gap - that lets users queue posts, company-page content, and group posts up to three months ahead, with a calendar view where clicking a past post surfaces its stats inline. Reviews frame it as bringing AuthoredUp to rough parity with dedicated schedulers, but note it's 'not as robust as dedicated scheduling platforms' - it handles the basics rather than advanced queueing or recycling logic.
Analytics dashboard
Tracks per-post impressions, reactions, comments, engagement rate, saves, and shares - metrics beyond what LinkedIn natively surfaces - plus a profile-growth timeline, a posting-time heatmap, and CSV/API export. Reviewers describe analytics as the retention driver: users who first sign up for the editor reportedly stay subscribed for the analytics once the formatting novelty wears off, since it's meaningfully deeper than LinkedIn's built-in numbers.
Why founders choose SparkVox.
Why recording-first repurposing wins for LinkedIn.
Different stages of the same pipeline
AuthoredUp makes you a better LinkedIn writer inside the feed. SparkVox removes the blank-page step by generating drafts from recordings before you open LinkedIn. The two tools solve adjacent problems, and many creators use both - AuthoredUp for polish and scheduling, SparkVox for sourcing content from calls and podcasts.
In-LinkedIn UX vs. recording-first creation
Reviewers consistently praise AuthoredUp for feeling like part of LinkedIn - draft, schedule months ahead, and check analytics without switching tools. That is its strength when you already know what to write. SparkVox is for when the content is on a recording but never becomes a post: upload the call or episode, review up to 15 drafts in your project's LinkedIn content strategy, then bring the finished draft into LinkedIn or publish directly.
Analytics that inform what to post next
A common AuthoredUp reviewer wish is smarter recommendations - suggestions on what type of content to post based on what has worked before. SparkVox Post Analytics tracks impressions and engagement on direct publishes and uses your top-performing posts when generating the next project. AuthoredUp shows you what worked; SparkVox feeds that signal back into new drafts automatically.
No LinkedIn tab required to start
AuthoredUp is a browser extension - it only works when you open LinkedIn on desktop. SparkVox runs at app.sparkvox.io on any device. Upload a call, training, interview, or podcast when you have it, then review theme-grouped posts in your project's LinkedIn content strategy when you are ready.
Which one should you pick?
SparkVox
SparkVox is for founders who have content on tape but never turn it into a LinkedIn pipeline.
AuthoredUp
AuthoredUp is a strong companion for committed LinkedIn creators who draft and schedule inside the feed and want formatting plus performance tracking - especially reviewers who value how native it feels inside LinkedIn.
SparkVox vs AuthoredUp: common questions.
I had your problem.Then I used SparkVox on myself.
I built SparkVox to manage LinkedIn for my podcast without it becoming a second job. That was five months ago. Now the same workflow also produces the posts that promote SparkVox itself. Same account, same person, one new tool.
