STETLY
Brand checks for creators and agencies

Every word on brand.
Before it goes live.

When everyone writes with the same AI, your voice is the one thing it can't copy. STETLY keeps it that way.

Why teams choose STETLY

Everything you publish, unmistakably on brand.

Stay on brand

Every post on brand, every channel.

Newsletters, blogs, social, websites. Every draft is matched to your style guide and tone of voice before you publish, so nothing off-style ever goes live.

Brand insurance

A policy against the off-brand mistake.

STETLY is the check that catches the off-tone line, the banned phrase, and the missing disclosure before your audience does, and before it costs you a deal.

Stay unique

Sound like you, not like a model.

When every competitor leans on the same AI and sounds the same, your voice is the one thing they can't copy. STETLY strips the generic tells and keeps you unmistakable.

Save time

Cut the review rounds.

First-pass QA happens in seconds, not feedback loops. Most drafts clear on the first pass, so the review rounds shrink and your team publishes without the back-and-forth.

Who's writing?
Try it on your own writing

How generic does your writing sound?

Paste a paragraph. We'll score how AI-generic it reads and highlight the tells, free.

Paste at least 150 characters

This is a real AI check. It scores how generic your writing reads and rewrites it on the spot. The full product goes further, checking every draft against your own style guide, voice, and brand contracts.

The objection we hear most

“Can’t I just tell ChatGPT to sound like me?”

You can. And ChatGPT will tell you it nailed it. Every single time.

Ask any model to grade its own draft and it passes itself. “Sounds just like you!” is not a check, it’s a compliment. And the prompt in your chat tab isn’t in your ghostwriter’s tab, or your VA’s. Your voice ends up living in five prompts, all slightly wrong, none of them checkable. Stetly puts it in writing instead: a brand profile built from what you’ve actually published, and a score against it on every draft, including the ones Stet writes for you.Every writer prompts differently, and every model happily confirms it matched the client’s voice. Nobody is checking against the real style guide, the banned list, or clause 3.1 of the contract. “Sound like Hayes & Co” is a vibe. A brand profile the client signed off on is a standard, and every draft is held to it, whether a writer typed it, ChatGPT drafted it, or Stet composed it.

The cost of manual QA

Half your drafts don't sound like you.Your content team is drowning in feedback loops.

AI writes fast, and so does your ghostwriter, your VA, and the ChatGPT tab you keep open. More goes out under your name than you can actually read. Meanwhile the voice people followed you for lives in your head, not in a doc anyone can check a draft against.

And the one off-brand line in a sponsored post is the one your audience screenshots, or the one that costs you the renewal.

AI writes fast. That's the problem. It turns out more drafts than any team can review, while your brand guidelines live in a PDF nobody opens, each client's tone lives in one account manager's head, and the contract clauses sit in a folder on Google Drive.

And one missed detail in a client's sponsored post means a re-shoot, a re-edit, or a call to the client you don't want to make.

Read it before they do.

First-pass QA in seconds, not a knot in your stomach. Most drafts clear on the first read, so you stop re-proofing everything that goes out with your name on it.

Cut the review rounds.

First-pass QA in seconds, not another lap through the team. Most drafts clear on the first pass instead of bouncing back for one more round of comments.

The AI content era

When everyone uses AI,
your voice is the differentiator.

Generic AI copy floods every feed, and the accounts that still sound like a person are the ones people keep following. STETLY keeps every post sounding like you, not like everyone else's model.Generic AI copy floods every feed, and a distinct voice is exactly what your clients pay you to protect. STETLY keeps every brand you run sounding like itself, not like everyone else's model.

01 · Voice

Sound like you, not like a model.

STETLY flags the tells (“leverage,” “unlock,” “delve,” “seamless”) and the cadence patterns ChatGPT bakes in by default. Your tone of voice document becomes a checklist.

02 · SEO

Rank above the generic.

Search rewards original perspective and penalizes mass-produced AI copy. Distinct voice, specific examples, and consistent terminology compound into authority, the things STETLY enforces every time you publish.

03 · Guidelines

AI drafts get checked too.

The same rules apply whether a human or a model wrote the first draft. Every piece is held to your style guide before you publish, so AI speeds you up without quietly drifting your brand.

New · Video

Your Reels are your riskiest content. Stop shipping them blind.

You script a Reel, shoot it, post it, and hope. There's no re-reading a video the way you re-read a caption, and "make it punchier" is not a note you can act on. Stetly scores video at both ends: plan the script before you shoot, and score the finished cut before it goes live.A client Reel is high effort, high visibility, and impossible to walk back once it's live. "Make it more engaging" helps no one. Stetly scores video at both ends, the script before the shoot and the finished cut before you send it for approval, so the notes are specific and the surprises are gone.

Brand insurance.
A policy against the off-brand mistake.

What's covered
  • The off-tone line that stopped sounding like the brand.
  • The banned phrase a client struck from the guide.
  • The missing disclosure that voids the contract.

Your sponsor contract has rules. Breaking one costs the deal. Upload the contract, and every draft is checked against its terms before the sponsor sees it.Your client's brand contract has 40 rules. Your writers remember six. Contracts compile into checkable rules per client, so a violation never reaches client review.

Brief ingestion

Drop the contract. We index every clause.

Your sponsor brief, the signed deal, the DM where they slipped in one more rule. STETLY turns each one into a living check, so the disclosure, the banned word, and the exclusivity window get caught before you post. Years of your own content become the corpus that keeps you sounding like you.Each client's contract, the signed agreement, the Notion brief, the Slack thread where the rules changed. STETLY turns every one into a living rule per client, so no writer has to hold all forty in their head. Years of past work become the corpus that catches drift before the client does.

Some thoughts on planning

A content calendar turns scattered posting into a system. Here's the thing nobody tells you about consistency: it isn't a personality trait, it's a setup. I post twice a week not because I'm disciplined but because Tuesday-me already did the thinking for Friday-me.

Reads great. Ranks for nothing.
