Claude

By AnthropicSan Francisco, United States3 products across 7 categories

Built for this. Best of the general options at holding a specific brand voice across a long batch of copy rather than drifting.

Copy.ai

By Copy.aiMemphis, United States1 product across 1 category

Strong fit. Runs repeatable marketing and sales workflows rather than one-off prompts — briefs, sequences, competitor summaries.

Rytr

By RytrWalnut, United States1 product across 1 category

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

Free plan

Free forever with no card required: 10,000 characters a month of AI content generation, and no
Month to month
$9/mo
Unlimited
Billed yearly
$7.50/mo
Unlimited plan −17%

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.

TextCortex

By TextCortexBerlin, Germany1 product across 1 category

Strong fit. A browser extension that writes inside whatever site you are already in, rather than a separate window you paste between.

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.

Writesonic

By WritesonicBengaluru, India1 product across 1 category

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.

Surfer SEO

By SurferWrocław, Poland1 product across 1 category

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.

Free plan

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.

How to read this list

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 blog writing?

There is no single answer, which is why this page lists 7 rather than one: Writesonic, Surfer SEO, ChatGPT, Claude, Copy.ai, Rytr, TextCortex. 3 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 7: ChatGPT, Claude, Copy.ai, 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.
