At a glance
AuthoredUp is a Chrome extension that upgrades LinkedIn's native composer with previews, formatting, and templates. Postbeam is a full LinkedIn platform with scheduling, advocacy, warm lead detection, and brand voice AI. Different tool, different scope.
What is Postbeam?
Postbeam is the LinkedIn-native pipeline platform built for B2B teams. Marketers draft posts in each teammate's voice, every scheduled post surfaces ICP-matched engagers as warm leads, and admins can scale advocacy across the team without spreadsheets. It publishes through LinkedIn's official partner APIs, so no Chrome extensions or automation flags ever touch your team's profiles.
Why Postbeam stands out
- Warm lead detection on every post: ICP-matched engagers get surfaced in-context, with the first outbound message pre-drafted.
- Per-person brand voice presets so every teammate sounds like themselves instead of one generic AI draft.
- Drafts-for-teammates workflow: admins write posts, teammates edit and publish as themselves in one click. No spreadsheets, no Slack chasing.
- Public, predictable pricing (rare in this category) with a real free trial so you can pilot before talking to sales.
- Claude and ChatGPT integration: pull your LinkedIn engagement data straight into the tools your team already uses.
- LinkedIn-safe publishing through official partner APIs.
What is AuthoredUp?
AuthoredUp is a Chrome extension, not a standalone app. It upgrades LinkedIn's native composer with better previews, formatting, and post templates, without pulling you into a separate scheduling dashboard.
AuthoredUp is a LinkedIn writing and formatting extension. It shows desktop and mobile previews of your post, adds bold/italic text formatting, and gives you templates, hooks, and snippets right inside LinkedIn.
Why AuthoredUp stands out
- Best-in-class LinkedIn post previews (desktop and mobile, before you publish).
- Rich formatting: bold, italic, and special-character support.
- Large library of hook templates and snippet shortcuts.
- Cheap entry price compared to full schedulers.

Pros and cons
Postbeam
- +Transparent, public pricing with a self-serve free trial
- +Warm lead detection on every post (the differentiator)
- +LinkedIn-native, not a retrofitted multi-network suite
- +Per-person brand voice for team content programs
- +Scales cheaper than any enterprise advocacy or social suite
- +Official LinkedIn partner APIs (zero account flagging risk)
- −LinkedIn-first by design, not a 12-network corporate comms platform
- −Newer product, so the template library is smaller than legacy tools
AuthoredUp
- +Best LinkedIn previews and formatting in the category
- +Massive template and hook library
- +Cheap entry price
- −Chrome extension only, so there's no multi-user workflow
- −No warm lead detection, advocacy, or pipeline features
- −Scheduling and calendar features are minimal compared to Postbeam or Buffer
Where Postbeam wins
- +Full scheduling calendar instead of inline LinkedIn composing.
- +Warm lead detection turns drafting into pipeline.
- +Team workspace with per-person voice for multi-user content programs.
- +No Chrome extension required, so no automation flag risk to your account.
Where AuthoredUp makes more sense
- →Best-in-class LinkedIn post previews (desktop and mobile, before publishing).
- →300+ hook templates and formatting shortcuts inside LinkedIn itself.
- →Cheaper entry price for individual writers.
- →Better fit if you only want a writing assistant inside LinkedIn's composer, not a full platform.
The verdict
AuthoredUp is a great add-on for individual writers who already live inside LinkedIn. It's not a replacement for a real scheduling and advocacy platform. Many Postbeam customers use both: AuthoredUp for inline previews, Postbeam for everything else.
