Write like your brand on its best day
Quillmark learns your brand voice from the writing you already have, then drafts blog posts, emails and product copy you only need to edit — with tone rewrites and SEO checks built into the editor.

Why it works
Built around how good writers actually revise
Write, rewrite and check without copying text between four tabs.
Rewrite
Same sentence, the tone you meant
Highlight a line that came out stiff and try it friendly, formal or confident side by side. Quillmark keeps your facts and product names intact and only changes how the sentence lands.
Brand voice
A voice profile you can actually read
After you add samples, Quillmark shows what it learned: how warm, direct or playful you are, your average sentence length, the words you love and the ones you never use. Move a slider and every new draft follows.
SEO
An SEO score that explains itself
Set a target keyword and watch the score move as you write. The checklist names exactly what's missing — keyword in an H2, a meta description under 155 characters, two internal links. It never asks you to stuff keywords.
- Learns your voice. Upload 5 to 50 samples: posts, newsletters, sales pages.
- Long-form drafts. Give it a working title and three bullet points.
- Rewrite by tone. Select any sentence and switch it to friendly, formal, confident or shorter.
- SEO while you write. Target keyword, headings, internal links, meta description and readability are scored live.
- Grammar and house style. Catches typos, passive voice and your team's pet phrases.
- Write in 12 languages. Draft in English, then adapt for German, Spanish or Japanese readers with the same voice profile — not a word-for-word translation.

Testimonials
“Our product pages went from "copy pending" to live in a week. The SEO checklist caught three missing meta descriptions.”
“I fed it 40 newsletter issues. The first draft used my sign-off and my habit of opening with a question. Slightly unnerving.”
Nadia HaddadNewsletter Writer“Four freelancers, one voice profile. Readers can't tell who wrote which post anymore, which is the whole point.”
Priyanka NairContent Lead“It flagged "utilize" every single time. Turns out I'd used it 31 times in one quarter. I've stopped.”

FAQ
Questions, answered
Can't find what you're looking for? A real person on our team replies within a few hours.
How many samples does it need to learn our voice?
Five pieces of at least 300 words each give you a usable profile. Around 30 pieces, mixing blog posts, emails and landing pages, usually pushes the voice-match score above 90%. Add or remove samples anytime; the profile updates within a minute.
Do you train AI models on my writing?
No. Your samples and drafts are used only to build your private voice profile and generate your drafts. They never train shared models, and our model providers are contractually barred from training on them. Delete a workspace and everything is gone within 30 days, backups included.
Is the output original?
Every draft is generated fresh from your brief, and long-form drafts run through a plagiarism check against the public web before you see them. Any matching passage longer than 12 words is highlighted so you can rewrite or cite it.
What counts as a long-form draft?
Anything over 500 words: blog posts, guides, case studies, long newsletters. Emails, product descriptions, ad variants and rewrites are unlimited on every plan and never count toward the monthly limit.
How does the SEO score work?
You set a target keyword and Quillmark checks about 20 on-page factors: keyword in the title and H2s, meta description length, internal and external links, image alt text, readability and heading structure. It can't promise rankings; it makes sure the basics are never the reason you don't rank.
Does it work with our CMS?
Every plan exports drafts as Markdown, HTML or .docx, and copying into most editors keeps formatting intact. Pro and Team can push drafts to any CMS via webhook, including title, slug, meta description and image alt text.
Can I cancel or switch plans?
Yes, from the billing page at any time. Upgrades take effect immediately and are prorated; downgrades apply at the next billing date. If you cancel, you keep access until the end of the paid month and can export every draft first.
