Strong fit. The cheapest usable option in this category by a wide margin, with a genuine free tier rather than a trial.

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.

Watch out: Now sold as an AI search visibility platform rather than the copywriter it started as, and priced accordingly, from $79 a month. Plans are capped on prompts and answers tracked, not seats, and agencies are quoted on a separate page.

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 product descriptions?
There is no single answer, which is why this page lists 6 rather than one: Copy.ai, Writesonic, ChatGPT, Claude, Rytr, TextCortex. 2 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?
5 of the 6: Copy.ai, ChatGPT, Claude, 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.
