STETLY vs Grammarly Business
Grammarly Business · now Grammarly Pro
Grammarly is the ubiquitous writing assistant — excellent at grammar, clarity, and tone correctness everywhere you type, with a light Style Guide and Brand Tones layer on its Business/Pro plans.
STETLY is a purpose-built publish-gate: every draft scored for voice Integrity and SEO Visibility, enforced against your real style guide and contracts, with the generic-AI tells stripped out.
They are complementary. Use Grammarly for correctness as you write; use STETLY for the brand-and-publish check before you publish. If you need real brand QA, STETLY goes deeper than Grammarly's brand layer.

How they compare, in detail
Correctness vs brand integrity
Grammarly is unmatched at the basics — grammar, clarity, tone — inline in nearly every text field you touch. But its brand features (Style Guide, Brand Tones) are a thin layer on top, not a true publish-gate with scoring and enforcement. STETLY exists for that brand check: it scores Integrity, flags the lines that drift, and enforces your style guide and contracts.
- Brand Integrity score + enforcement
- Style guide & contracts as rules
- Best-in-class correctness
- Light Style Guide / Brand Tones layer
Keeping your voice
Grammarly's suggestions optimise for correctness and can quietly flatten a distinctive voice toward the generic — the opposite of what creators and agencies want. STETLY is built to keep you unmistakable: it strips the generic AI tells and protects the lines that make you sound like you.
- Protects distinctive voice
- Removes generic AI tells
- Can homogenise voice toward "correct"
SEO & contracts
Grammarly has no SEO visibility scoring and no contract or disclosure compliance. STETLY scores SEO Visibility alongside Integrity, and enforces sponsor and client contracts before you publish.
- Dual Integrity + SEO Visibility score
- Sponsor & client contract enforcement
- No SEO score; no contract compliance
Pricing for teams
Grammarly is cheap per seat (~$15/user/month) but per-seat cost scales linearly with headcount — a 10-person agency pays roughly $1,800/year. STETLY is flat per month, so the price does not climb as the team grows.
- Flat monthly pricing, not per-seat
- ~$15/seat/mo — scales with headcount
Pricing
Free, then €29 / €89 / €249 per month (flat, not per-seat).
Pro (formerly Business) ~$15/user/mo billed annually; Enterprise custom.
Grammarly is cheaper for one person; STETLY's flat pricing wins as the team grows, and it does a brand-QA job Grammarly's plans only lightly touch.

Questions
- Should I replace Grammarly with STETLY?
- Not necessarily — they do different jobs. Grammarly is correctness as you write; STETLY is the brand-and-publish check before you publish. Many teams use both.
- Doesn't Grammarly already check brand voice?
- Grammarly Business/Pro has a Style Guide and Brand Tones layer, but it is light. STETLY is purpose-built for brand QA — scoring Integrity and SEO and enforcing style guides and contracts.
- Is STETLY cheaper than Grammarly Business?
- For one seat, Grammarly is cheaper. STETLY's flat pricing pulls ahead as your team grows, because it is not charged per seat.
