Write marketing copy faster

The problem

Marketing copy is the work that everyone can technically do and nobody wants to start. A landing page needs writing, so it waits. An email sequence needs five versions, so it becomes two. And when several people do write, the company sounds like several companies, because nobody wrote down what the voice is.

There is a quality trap underneath the speed problem. Rushed copy is not usually bad grammar, it is vagueness: claims without specifics, benefits without evidence, sentences that could describe any competitor. That reads as filler to the person you are trying to convince, and it is the failure mode that gets worse, not better, when you produce more of it faster.

What AI can actually do here

Three separate jobs hide under "writing faster", and the tools split along them.

The first is starting. A generative tool turns a brief into a draft in seconds, which removes the blank page. This is the biggest real gain, because the blank page is where the hours go.

The second is consistency. Brand voice features let you define how your company sounds and generate against that definition, so five people produce copy that reads as one organization. This matters more as the team grows and is nearly pointless if you are one person, because you already are the voice.

The third is correction. A writing assistant catches mistakes, adjusts tone and rewrites clumsy sentences inside the tool you are already writing in, without generating anything.

What none of them do is know your customer, your differentiator or your evidence. Generated copy defaults to the average of everything written about your category, which is precisely the vague, could-be-anyone prose that fails. The workflow that works is: you supply the specifics and the claims, the tool supplies the draft, you edit. Skipping the last step is how companies publish content that reads as machine-made.

How the tools differ

Jasper is built for marketing teams. Brand Voice is its centre, with 2 voices on Pro and unlimited on Business, plus agents for marketing workflows and a browser extension that works in Gmail, WordPress, HubSpot and LinkedIn. It is paid only, at $69 per month per seat billed monthly or $59 billed annually, with a 7-day trial. The per-seat price is the reason it suits teams and not individuals.

Copy.ai splits into two products. Its Chat plan is $29 per month, or $24 billed annually, and includes 5 seats with unlimited words and a choice of OpenAI, Anthropic and Gemini models, which is unusually generous for a small team. Its workflow plans, for automating repetitive content operations at volume, start at $1,000 per month, so there is no gradual path between the two.

Grammarly is the correction layer rather than a generator. Free for spelling, grammar and tone detection, EUR 12 per month for Pro with full-sentence rewrites, tone adjustment and 2,000 AI prompts per member. It works where you already write, which is why it gets used when standalone tools get abandoned.

When you don't need a tool

If you write occasionally and already have a general AI assistant, you probably have the generation half covered. A dedicated platform earns its price through brand voice consistency across a team and workflow automation, and if you are one person, neither applies.

If your copy is underperforming because you do not know what to say, a faster writing tool produces more of the wrong thing. Talk to five customers and use their words. That research changes conversion more than any generator, and it costs nothing but time.

And if your problem is proofreading rather than drafting, use the free tier of a writing assistant and stop there. See Jasper vs Copy.ai if you have decided you need a platform and are choosing between the two.
