The Problem

AI content killed LinkedIn trust.

Your audience now assumes every polished post was written by ChatGPT or Claude. Even if you wrote every word yourself, you're paying the penalty.

📉

Engagement is tanking

LinkedIn engagement on text posts dropped 32% since 2024. People scroll past "AI-looking" content without thinking.

💬

"Did you even write this?"

The most common DM founders get after posting. Every time someone questions your authenticity, you lose credibility you can't get back.

🧠

AI detectors don't work

GPTZero, Originality.ai, they all produce false positives. Good human writing gets flagged. Bad AI writing passes. They solve the wrong problem.

💰

Trust = Pipeline

For founders selling services, every post is a top-of-funnel touchpoint. When trust erodes, so does your pipeline. This isn't about ego, it's revenue.

The real issue: there's no way to prove process, only output.

AI detectors analyze the text. Humanpost records the journey. That's the difference between guessing and knowing.

Most "thought leadership" on LinkedIn is now indistinguishable from ChatGPT or Claude output.

I've been writing my own posts since 2019. Every revision, every awkward pause while I search for the right word, that's what makes writing mine.

How it works

Three steps.
No tricks.

I t h i n k . .
01

Write like you always do

Install the Chrome extension. Open LinkedIn. Start typing. Humanpost silently captures your writing session in the background.

What we record: Keystroke timing, pause patterns, revision sequences, cursor movements. We never record what's on your screen or other tabs.

02

Get your Human Score

Our engine analyzes behavioral signals that distinguish human writing from copy-paste or AI dictation.

Key signals: Think-type ratio, micro-hesitation patterns, revision depth, session continuity. Each scored independently, then combined.

03

Publish with proof attached

One click adds a verification link to your post. Your audience can see the score, the writing duration, and your process.

Tamper-proof: Each session is hashed and timestamped to an immutable log. You can't edit the proof after publishing. Neither can we.

Built to be skeptic-proof

"But can't someone just retype AI text?"

Short answer: they could try. Long answer: the behavioral fingerprint of retyping is fundamentally different from composing. Here's why.

✍

Think-type patterns

When you compose, you pause before new ideas. When you retype, pauses are evenly distributed. We measure the variance.

🔄

Revision behavior

Real writers revise mid-thought, rewriting sentences, changing word order, deleting paragraphs. Retypers don't. The edit graph looks completely different.

⏱

Micro-hesitation analysis

Humans hesitate 200-400ms before uncommon words. Retypers don't, they already know what comes next. This signal alone catches most gaming attempts.

🔒

Immutable proof chain

Every session is cryptographically hashed at capture time. You can't retroactively edit a proof. The verification page links to the raw hash for anyone to audit.

FAQ

Common questions.

How do I install the Chrome extension?
Visit the Chrome Web Store, click "Add to Chrome," and sign in with your LinkedIn account. Setup takes about 30 seconds. Once installed, Humanpost adds a lightweight editor that appears when you start a post on LinkedIn.
Does Humanpost slow down my writing or change LinkedIn?
No. The extension runs silently in the background. It doesn't modify LinkedIn's interface or add any lag to your typing. You write exactly the same way you always do.
Can I upload images with my post?
Yes. The Humanpost editor includes an image picker. Attach a single image (JPEG, PNG, GIF, or WEBP up to 10MB), and it gets published alongside your verified text on LinkedIn.
What happens if my Human Score is low?
A low score doesn't prevent you from publishing. It means the behavioral signals looked unusual for that session, maybe you typed unusually fast or had very few revisions. You can always choose not to include the verification link if you're not happy with the score.
Can I edit my post after publishing with proof?
You can edit the LinkedIn post text like any normal post, but the verification proof is locked at publish time. The proof page will always show the original verified version. This is by design, it's what makes the proof trustworthy.
Is my writing data stored or shared?
Your keystroke timing and patterns are used only to compute your Human Score. We never record screen content, other tabs, or anything outside the editor. Raw keystroke data is not shared with third parties.
Does Humanpost work on mobile?
Currently Humanpost requires the Chrome desktop extension, so it works on desktop only. Mobile support is on our roadmap.
