A copywriter agent that
never misses a deadline
A good copywriter is expensive, booked out, and still a single point of failure when a campaign needs forty variants by Friday. We build a copywriter agent that drafts from a brief in your brand voice, backs every claim with a source, and hands the final read to a person before anything goes live.
The role today
A campaign brief lands on a Monday and needs ad copy, a landing page and three email variants by Friday, and the one copywriter who knows the brand voice is already behind on last week’s batch. Briefs get thinner as deadlines compress, so writers guess at claims instead of checking the spec sheet, and a wrong number in a product page sits live for weeks before anyone notices. Agencies solve this by throwing more writers at it, which multiplies the voice drift problem instead of fixing it.
What the agent takes over
The agent takes a brief, your existing brand voice guide and the relevant fact sheet (specs, pricing, policy), and drafts the full set: ad headlines and body copy, a landing page outline with sections filled in, email variants, product page copy. It keeps a memory of your brand’s vocabulary, the phrases you always cut, and the claims that need a source, so a draft for a new product reads like it came from the same writer as the one from six months ago. For A/B tests, it produces several angles from one brief rather than one draft stretched thin. Every factual claim, a spec, a price, a shipping promise, is checked against your sheet before the draft is marked ready for review, and a draft that cannot be verified is flagged instead of guessed at.
Over time the agent’s memory of your brand grows with it: which phrases customers respond to, which claims legal has already blanket-approved, which products have seasonal messaging that needs to change on a schedule. A new writer joining your team inherits that memory instantly instead of spending a month learning the brand by trial and error, and a draft for a product launched today reads consistent with one launched a year from now because the underlying voice guide, not a person’s memory of a meeting, is what the agent works from.
What stays with humans
Approving the final copy, deciding the campaign angle and tone for a sensitive launch, and signing off on anything making a legal or medical claim stay with your team. The agent drafts and checks facts; a person decides what actually represents the brand.
Guards
Nothing publishes without a human reading it first: every draft lands in a review queue in Telegram or your doc tool with the source for each claim attached. A claim that cannot be matched to the fact sheet is flagged in the draft itself rather than silently included. All drafts and their sources are logged, so a published piece can be traced back to what it was checked against, and a one-message kill switch reverts to manual drafting. New brand voices or new content types launch in a dry run first, drafts generated and reviewed internally but not yet shown to a live review queue, until the fit is confirmed. If you ever bring copywriting fully back in-house, we hand over the voice guide, the fact sheet and the full draft history, documented so a new writer or agency can pick it up without starting over.

FAQ
How much does a copywriter agent cost?
From $1,800 for one brand voice and up to four content types (ads, landing pages, emails, product pages), live in 2 to 3 weeks. A team covering a second brand or more content types usually runs from $3,000.
How long does it take to go live?
Two to three weeks from brief to a working draft pipeline: a week to build the voice guide and test drafts against your edits, a second week to wire it into your review tool and tune the claim-check.
Which channels and tools does it work with?
It writes for whatever you publish to: ad platforms, your CMS, email tool, product catalog and social captions. It does not post on its own; drafts land in a queue for your copy lead to approve.
What if it gets something wrong?
Every draft is checked against your fact sheet before it is marked ready, and a human always reads before publishing, so a wrong claim gets caught at review, not after it is live. We log every draft and its source.
What about our data and security?
Your brand voice guide, past copy and fact sheet stay in your own storage or ours, your choice. Nothing trains a shared model; the agent only reads what you give it.
