STETLY vs Markup AI
Markup AI · formerly Acrolinx
Markup AI (the relaunch of Acrolinx) is an enterprise content-governance platform — strong brand-voice and terminology checking, deep API/MCP pipeline integration, and real enterprise logos.
STETLY is built for creators and agencies, not enterprise doc teams: transparent flat pricing instead of a sales call, a dual Integrity + SEO Visibility score, and contract-aware brand insurance Markup does not offer.
Pick Markup if you are a large enterprise standardising content governance across thousands of docs. Pick STETLY if you publish for clients or an audience and want an affordable, self-serve check you can set up today.
Built in the EU · Data stays in Frankfurt · Your content never trains a model

How they compare, in detail
Brand voice & style enforcement
Both tools check a draft against your tone of voice and style guide and flag what is off. Markup AI brings two decades of Acrolinx terminology and governance pedigree — it is genuinely strong here, especially for large, controlled vocabularies. STETLY focuses the same idea on the way creators and agencies actually work: paste a draft from anywhere, get an Integrity score, and see the exact lines that drift from your voice.
- Integrity score on every draft
- Works on content written in any tool
- Strips generic AI tells to keep you unmistakable
- Deep terminology governance
- Editorial assistance in 40+ authoring environments
- Built for high-volume technical docs
SEO & AI search
Markup AI markets "citability" — making content easy for LLMs to surface. STETLY scores SEO Visibility next to your Integrity score, so you can see the trade-off between ranking and voice in one view and fix one without sacrificing the other — something neither pure-SEO tools nor governance suites do.
- Dual Integrity + SEO Visibility score
- Shows the voice-vs-SEO trade before you make it
- AI citability scoring
- No classic SEO visibility score surfaced
Contracts & brand insurance
This is where the products diverge most. STETLY compiles your sponsor or client contracts into checkable rules — a missing #ad disclosure, a banned competitor mention, an off-limits claim is caught before the draft reaches the sponsor or client. Markup AI has no comparable contract-aware compliance.
- Sponsor & client contracts compiled into rules
- Catches disclosure, competitor-mention & claim violations
- No contract-aware compliance
Pricing & access
Markup AI offers a generous free tier (1M tokens/month) and then jumps to a custom "contact sales" enterprise plan — leaving no self-serve paid tier for a growing creator or small agency. STETLY publishes flat monthly pricing from free up to €249, billed on what you publish, not per seat.
- Public flat pricing, free to start
- No per-seat penalty for agency teams
- Free tier, then enterprise sales
- No self-serve mid-market tier
Pricing
Free, then €29 / €89 / €249 per month (flat, not per-seat). Annual = 2 months free.
Free Professional tier (1M tokens/mo). Paid is "Custom" — contact sales, no public price.
For a small agency that needs more than the free tier but isn't ready for an enterprise contract, STETLY has a tier; Markup's pricing has a gap.

Questions
- Is Markup AI the same as Acrolinx?
- Yes. Acrolinx rebranded to Markup AI; acrolinx.com now points to the Markup AI relaunch. The enterprise content-governance heritage carries over.
- Does STETLY replace Markup AI for enterprises?
- Not for a large enterprise standardising governance across thousands of documents — Markup is built for that. STETLY is the better fit for creators and agencies who want a focused, affordable, self-serve check.
- What can STETLY do that Markup AI cannot?
- Score SEO Visibility alongside brand voice in one view, and enforce sponsor or client contracts (disclosures, competitor mentions, banned claims) before you publish.
The check between draft and publish — every word matched to your voice, your style guide, and your brand contracts before you publish.
