Does your writing sound like AI?
A free AI writing checker that flags exactly what makes your text read like AI, from em dashes to buzzwords like delve and leverage. Paste a draft, or pull a public LinkedIn post straight from its link, and fix the tells before you post.
AI tells are the patterns language models lean on: em dashes, hype openers, words like delve and game-changer, robotic transitions, and walls of hashtags. This checker scans your text in your browser, scores how human it reads, and shows you what to change.
Runs entirely in your browser. A style guide, not a detector. Nothing you paste is uploaded or stored.
The fastest way to lose a reader is to sound like AI
On a busy feed, the first whiff of AI writing kills trust. Clean up the tells and your point lands. Pair it with a sharper hook and the right formatting and the post earns the read.
Catch what readers feel
People sense AI writing even when they cannot name why. This shows you the exact words and patterns giving it away, so you can fix them before you post.
Built on the real giveaways
Em dashes, the AI buzzword lexicon, hype openers, the 'not just X, it's Y' tic, emoji bullets, robotic transitions, and hashtag stuffing, each flagged in your text.
A fix for every flag
Each tell comes with a plain-language fix, so you rewrite in seconds instead of guessing what felt off.
A score you can act on
One human-ness score from 0 to 100 with a clear verdict, so you know the moment a draft is ready to ship.
Honest by design
A style guide, not a detector. It flags patterns that read like AI and never pretends to prove how a text was written.
Private by default
Everything happens on this page in your browser. Your draft is never uploaded, logged, or stored, so even unpublished ideas stay yours.
How it works in 3 steps
No software, no signup. Check your draft and clean it up in under a minute.
Paste your draft, or a link
Drop in a post, caption, email, or any text, or switch to From a link to pull a public LinkedIn post by its URL. The example button loads a deliberately AI-sounding post so you can see it work.
See the tells light up
The checker highlights every flagged word and pattern as you type, grouped by how strong a giveaway each one is.

Frequently asked questions
What to know about AI tells and how to remove them.
What are AI tells in writing?
AI tells are the patterns that large language models lean on far more than people do. The big ones are the em dash, hype openers like 'thrilled to announce', a recurring buzzword lexicon (delve, leverage, tapestry, game-changer, seamless), the 'it's not just X, it's Y' construction, essay transitions like 'moreover' and 'furthermore', emoji bullet lists, and walls of hashtags. This checker scans for all of them and shows you where they are.
Why is the em dash a sign of AI writing?
Most people rarely type a true em dash because it is not on a standard keyboard, so they use commas, periods, or a hyphen instead. AI models produce the em dash constantly. That mismatch makes it the single most recognised giveaway. It is also why Blendin's own writing engine never uses em dashes. The checker flags em dashes, en dashes, and double hyphens so you can swap them for a comma or a period.
Is this an AI detector?
No, and that is deliberate. So-called AI detectors claim to prove whether a machine wrote something, and they are notoriously unreliable. This is a writing-style guide. It flags the patterns that make text read like AI and explains how to fix each one. It never pretends to know how your text was actually produced.
How do I make AI text sound human?
Cut the em dashes, delete the buzzwords, and open with the point instead of an announcement. Vary your sentence length so the rhythm is not uniform. Replace essay transitions with a line break or nothing. Trade emoji bullet lists for plain lines. Keep specifics, names, and real opinions, which is what AI tends to sand off. Paste your draft above and the checker walks you through each fix.
Which words make writing sound like AI?
The usual suspects include delve, leverage, tapestry, realm, plethora, myriad, seamless, foster, elevate, unlock, robust, game-changer, best-in-class, cutting-edge, and testament to. None are banned words, but in clusters they read synthetic. The checker highlights each one it finds and suggests cutting it or swapping in a plainer word.
Is the AI tells checker free?
Yes. It runs entirely in your browser with no signup, account, or credit card. Paste your text and the analysis appears instantly. Nothing you paste is uploaded, logged, or stored.
Can I check a LinkedIn post by its link?
Yes. Switch to the 'From a link' tab, paste a public LinkedIn post URL, and the checker pulls the post's wording and analyzes it. It reads only the public text of the post, the same text anyone can see, and it works only for public posts. Private posts and anything behind a login cannot be read.
Does it work for more than LinkedIn posts?
Yes. The tells it looks for are universal to AI writing, so it works on any short text: LinkedIn and Instagram captions, Threads, emails, newsletters, landing-page copy, or a cover letter. Paste whatever you are about to send.
Do you store the text I paste?
No. The checker is fully client side. Your draft never leaves your device, is never sent to a server, and is gone when you close the tab. That is why even unpublished or sensitive drafts are safe to check here.
