Watch out: Output needs more editing than the pricier tools, which is what you are trading for the price. The free tier is 10,000 characters a month, a few articles at most, and neither paid tier caps generation — the extra money buys tone matching across brands rather than volume.

Watch out: Breadth over depth against a dedicated tool. There is only one paid tier before Enterprise, and the model usage it includes is footnoted rather than stated, so check the allowance before committing.

Built for this. Scores a draft against what already ranks for a term, and says which sections and phrases are missing. Built around the editor rather than a report.

Watch out: It optimises for resemblance to current winners, which is a floor rather than a ceiling. Paid from the start, and the entry plan is not cheap.

Two things separate these and both are on every card.
Fit
Whether a tool is built for this job, a strong fit for it, or
able to do it without that being its focus.
Free plan
Whether there is a tier you can keep using rather than a
trial that expires.
The order
Fit first, then a free plan, then alphabetical. There is
no score, no weighting we decline to publish, and nothing on this site a company can buy.
Questions
What is the best ai for content marketing?
There is no single answer, which is why this page lists 9 rather than one: Surfer SEO, Writesonic, Copy.ai, ChatGPT, Claude, Canva Magic Studio, Gamma, Rytr, TextCortex. 5 of them are built for this kind of work rather than able to do it. Start with a free one.
Which of these have a free plan?
7 of the 9: Copy.ai, ChatGPT, Claude, Canva Magic Studio, Gamma, Rytr, TextCortex. Free means a real free tier you can keep using, not a trial that expires.
How was this list chosen?
By hand, from the 750 products this site tracks, and it is checked against the catalogue on every build — a product renamed or removed breaks the build rather than quietly disappearing from here. Nothing on this site can be paid for: no listing, no position, no wording.
