Dedicated AI writing tools sell brand voice, templates and team workflows on top of a language model. Before you pay, it is worth knowing what they cost and what you are paying for.

This article lays out the published pricing for Jasper, Copy.ai and Grammarly, checked October 20, 2026. It is research-based, not a hands-on test, and we do not rank output quality.

One note: general-purpose AI assistants also write marketing copy, including Claude, which is made by Anthropic, the company behind this assistant. Because we cannot be neutral about that, we do not rank assistants here. We compare only the dedicated tools below.

Copy.ai pricing

The Chat plan lists unlimited words in chat and access to OpenAI, Anthropic and Gemini models. The page did not show a free plan. Workflow plans start at $1,000 a month billed annually, which is well beyond a solo operator's budget.

  • Reasonable entry price

What to watch

  • Workflows are priced for large teams
  • No free plan shown

Grammarly plans

Free includes mistake checking and tone visibility. Pro adds full-sentence rewrites, tone adjustment, AI-text detection and plagiarism detection. The page did not say whether the price differs by billing period.

What works

  • Useful free plan
  • Lower price than dedicated content platforms

What to watch

  • Not built to produce long drafts from scratch
  • AI prompts are capped

Which one should you choose?

  • If you mostly edit your own writing, Grammarly is the lowest-cost fit.
  • If you produce on-brand content for a team, Jasper is aimed at that.
  • If you want multi-model chat for a small team at a modest price, Copy.ai Chat is the entry point.

Whatever you pick, read AI-written copy before publishing, and do not claim features your product lacks.

How we compared

We read each vendor's pricing page on October 20, 2026. We did not compare output. We excluded Writesonic because its current pricing focuses on AI search visibility tracking rather than general writing.

Frequently asked questions

Is AI-written content OK to publish?

Search engines focus on whether content is helpful, not how it was made, but you remain responsible for accuracy.

Should I pay for a dedicated tool?

Try free plans first. Pay only if brand voice or team workflows save you real time.
