The AuthoredUp Alternative for People Who'd Rather Not Open the Composer at All

What AuthoredUp is, and what Liftli is

Let me be fair to AuthoredUp before I say a word about Liftli, because it's a genuinely well-regarded tool and I don't want to muddy that. AuthoredUp is publicly positioned as a browser extension for LinkedIn. It layers a better writing experience directly onto LinkedIn itself: rich formatting like bold, italic, and bullets; post previews so you can see exactly where the "…see more" fold lands before you publish; drafts; reusable snippets; and post analytics. Its real strength is that it lives right there in the composer, so the moment you sit down to write a LinkedIn post, the better surface is already in front of you. For details on its exact current feature set and pricing, check their site — I'm describing the category, not quoting their internals.

Liftli is a different shape entirely, and I think the honest way to compare them is to admit they're barely the same category. Liftli is an MCP — an agent — that runs inside the AI you already use (Claude today, with ChatGPT and Cursor next), and it covers LinkedIn, X, and Substack. Instead of giving you a nicer place to write, it does three things a composer extension doesn't try to: it decides what's worth posting from your real week, it drafts in a voice it extracted from how you actually write, and it publishes and schedules through official platform APIs behind a one-tap approval gate, from your phone if you like.

So the split is clean. AuthoredUp is about the writing surface. Liftli is about the deciding and the doing. Neither replaces the other cleanly, and I'd rather you understand that than pick Liftli for the wrong reason.

The one question worth asking any LinkedIn tool

This is a section I want to write carefully, because it's easy to turn into fear-mongering and I won't do that. AuthoredUp is a respected tool and I have no reason to think it does anything against LinkedIn's rules — I don't know its internals, and neither should you assume you do. So this is a neutral question, not an accusation.

Here's the fair framing. Any browser extension lives inside LinkedIn's own page. LinkedIn's User Agreement restricts scraping and automation done through extensions, and enforcement is real — Kleo, an extension with roughly 70,000 users, shut down in mid-2025, which tells you LinkedIn does act. But — and this matters — an extension that only formats text in your own browser is a very different, much lower-risk thing than one that automates actions on your behalf. Formatting your own draft is not the same as botting. I won't pretend otherwise.

So the honest, defensible point is just this: an extension touches your account from inside LinkedIn's page, and it's worth asking any tool — AuthoredUp, Liftli, anything — exactly how it touches your account, then reading the answer literally. Liftli's answer is that it publishes and schedules through official platform APIs and never uses extensions, scraping, or bots. That's the contrast. Ask AuthoredUp the same question and weigh their answer on its own terms.

Liftli vs. AuthoredUp, feature by feature

Where a AuthoredUp cell is vague, that's deliberate: I describe public positioning, not a feature audit, and I don't track anyone else's roadmap. "Check their site" means I don't know, not that the answer is no.

What only Liftli does

These are things Liftli does that a composer extension isn't built to do. I'm listing what Liftli does, not what AuthoredUp lacks — for AuthoredUp's actual feature set, check their site.

• It decides, not just formats. Liftli reads your real week — voice notes, call transcripts, git commits, chat threads, news you care about — and proposes what's actually worth posting, so the blank composer problem mostly disappears.
• Your voice, extracted and persistent. It builds a voice profile from how you already write and drafts in it, per person. This matters because an Originality.AI study of 3,368 LinkedIn posts in 2025 found detectably-AI posts underperform human writing in most professional niches — so drafts that sound like you, not like a robot, is the whole point.
• Plan → draft → critique → revise. Every post goes through an internal critique pass before it reaches you, so what you approve has already been argued with once.
• Publish and schedule across three platforms. LinkedIn, X, and Substack, all through official APIs, behind one-tap approval — no extension sitting inside any platform's page.
• Warm-lead scoring and weekly recalibration. It scores who's worth engaging and adjusts your plan every week based on what actually landed.
• Agent-native. Because it's an agent, you can ask it for arbitrary multi-post workflows in plain language — "turn this call into a LinkedIn post, an X thread, and a Substack note, schedule them across the week" — and it just runs.

When AuthoredUp is the better fit

I'd genuinely point you to AuthoredUp in a specific situation, and I'd rather say so than pretend Liftli is for everyone.

If what you want is a better writing and formatting surface inside LinkedIn's own composer — you already know what you want to say, you enjoy writing it yourself, and you just want bold and bullets, a clean preview of where the "see more" fold lands, and somewhere to keep drafts and snippets — then an in-composer extension is a genuinely good fit, and Liftli isn't that. Liftli decides and drafts for you; if you don't want that, it's the wrong tool. Check AuthoredUp's site for their current features and pricing.

One thing worth knowing: if it's only the formatting and preview part you're after, Liftli gives that away free, no login, right in your browser. There's a LinkedIn text formatter for Unicode bold, italic, underline, strikethrough and a dozen more styles plus lists, and a post preview tool that shows the line-aware see-more fold on both desktop and mobile. So you can get the formatting-and-preview surface for free from us and still write everything yourself — the two aren't mutually exclusive. And if you want to see the deciding-and-drafting side, here's how Liftli actually works.
