Content Writing Tools for a One Person Blog, by Job

Four of the nine pages ranking for content writing tools are roundups written by companies that sell one of the tools, and three of the four put their own product in the list. AIOSEO ranks itself first of twelve. Kontent.ai is fourth of ten on its own page. Surfer sits fifth of ten on Surfer's blog, in a post dated this month. The fourth roundup belongs to an agency that sells content services. The lists run to eight, ten and twelve tools, and every one of them is priced for a team, which is fine if you have one.

I run several small blogs by myself out of one repository, so here's the version for one person. A writer needs seven jobs done, research, drafting, grammar, readability, an SEO check, images and publishing, and below is what each job costs at three budgets, nothing, about $20 a month, and about $100, using the vendors' own pages on 15 September 2026. The short answer is that the free stack covers six of the seven jobs, the $20 buys a better model, and the $100 buys an SEO editor that comes with two seats you'll never sit in.

Seven Jobs At Three Budgets

The table is the article. The rest is the reasoning behind each row.

Six of the seven jobs have a free tool that does the job properly rather than a free tier that does a fraction of it. The one exception is the SEO check, where the free option is your own time, and I'll argue below that for one person it's the right option anyway.

The Seats You'd Pay For And Never Use

Here's what the roundups quote for the SEO editor and what the vendor pages show.

Surfer is "$79/month" in AIOSEO's list and "$89/month" in the agency's. Surfer's pricing page today shows Discovery at $49 a month with one seat and 120 documents, and Standard at $99 with three seats and 360 documents, on the annual toggle it displays by default. Neither roundup figure matches a current tier, which usually means the plans moved after the roundup was written and the number stayed.

The point for one person is the seat count. Standard's $99 is $33 a seat if three people use it and $99 a seat if one does. Discovery is the plan a solo writer wants and it's the one neither roundup names. At 120 documents a month it's about 41 cents a document if you used every one, and no solo blog publishes 120 posts a month, so the real cost per post is whatever $49 divided by your actual cadence comes to. Four posts a month is $12.25 each.

Frase is the same shape one tier down. Starter is $49 monthly or $39 annual for ten articles, 25 AI generations and one seat. That's $4.90 an article on monthly billing or $3.90 on annual, if you write all ten. Professional at $129 gives 40 articles and three seats, and the agency roundup quotes Frase at "$14.99 to $44.99", which matches nothing on the page I loaded. I'd take that as another moved tier rather than an error.

Both tools are good at the thing they do, which is showing you what the pages already ranking contain and scoring your draft against them. My reservation is only about who they're built for. The three-seat plans exist because agencies have three writers. For one writer the cheapest single-seat plan is the whole decision, and it's $49 at both vendors.

The SEO Check You Can Do For Nothing

This is the row where I'd spend the least, and it's the row the roundups spend the most words on.

What an SEO editor does is read the top ten for your keyword, count what they cover, and tell you what's missing from your draft. You can do that with a browser and half an hour. Open the ten pages, note the headings, note the questions in the People Also Ask box, and write down the one thing none of them has. The tool does it faster and gives you a score. The score is the part I'd be careful with, because a draft that matches the top ten's coverage is by construction a draft that adds nothing to it, and the only artifact that ranks a new page is the one the others lack.

Search Console is the other half and it's free. It tells you which queries a page already shows for and at what position, which is the number no editor tool can see because only Google has it. For a post that exists, that report beats any content score.

So my $0 row for the SEO check isn't a compromise. It's the method. The paid row is for when your time costs more than $49 a month, which for a one-person blog is a real threshold and not one most of them cross early.

What The Free Generators On This Page Are

Four of the nine results aren't roundups. They're free text generators from Copy.ai, Copymatic, Ahrefs and HubSpot, and they rank because the phrase includes the word "tools" and each of those pages is one.

I've priced Copy.ai and Copymatic in the copywriting tools comparison and won't repeat the figures. HubSpot's free writer needs a HubSpot account and says on its own page that "Most generative features are paid". Ahrefs offers a hub of free generators. The reason these pages exist is the subject of the free AI writing tools piece, and the one-line version is that a free generator is a doorway. That's fine. It's just not a content writing tool for one person so much as a demo of somebody's paid product.

For drafting, the honest free tool is a general chat model, which is why the Surfer roundup, to its credit, leads with four of them, ChatGPT, Perplexity, Claude and Gemini, before it gets to Surfer.

Grammar And Readability Are Solved For Free

Grammarly Free gives "100 prompts / month" and spelling and grammar checking with no cap stated, and Pro adds the sentence rewriting at $12 a month billed annually or $30 monthly. For a blog post the free tier is the level I'd use anyway, since the paid tier changes more of your sentences and that's not always a favour. I sorted the editing tools by how much of your sentence survives in the AI editor writing comparison, and the free tier sits at the conservative end, which for grammar is where you want it.

Hemingway's web editor is free, and its page lists a free readability checker, grammar checker, paraphraser and proofreader. The desktop app is $19.99 once for Mac or Windows. Hemingway Plus has a two-week trial with no card, and its price isn't on any page my tooling could open, so the $12.50 a month the agency roundup quotes is the only figure I have and I'd verify it before relying on it.

That's two of the seven jobs done for nothing by tools that have been doing them for years, and neither roundup treats them as anything other than a line item.

Images, And The License Nobody Quotes

The Medium post at position eight recommends Unsplash, and it's right. Unsplash's license says "All images can be downloaded and used for free" for "Commercial and non-commercial purposes" with "No permission needed", and attribution isn't required. The restrictions are that "Images cannot be sold without significant modification" and that you can't compile them to build a competing service. For a blog hero image, none of that bites.

I generate most of my own images locally these days, but for anyone who doesn't, the free image job has a free answer with a clear license, and it's worth knowing the two restrictions before you put an Unsplash photo on a product you sell.

The Roundups, And What's Theirs

Since every roundup on this page claims testing, here's who wrote each and what they're selling.

I don't think any of these is dishonest, and AIOSEO discloses that its content is reader-supported. But a list where the author's product is first, a list where the author's product is fourth and nothing has a price, and a list where the author's product is fifth after four free chat models are three different kinds of document, and the position of the house product tells you more about each than the testing sentence does.

Questions That Come Up

Which tool is best for content writing? For one person, a free chat model for the draft, Grammarly Free and Hemingway's web editor for the pass afterwards, and your own reading of the top ten for the SEO check. That's $0 and covers six jobs. The seventh, images, is free too. If you add one paid tool, make it the model.

What are the 5 most popular AI tools? On this results page, ChatGPT, Claude, Gemini, Perplexity and Grammarly appear most often across the four roundups. That's frequency of mention on nine pages, not a usage figure, and I don't have one.

What are the 7 types of writing? Not a question about tools. The usual list is expository, descriptive, persuasive, narrative, technical, creative and academic, and a blog post is usually the first two with a little of the third. No tool on this page cares which one you're doing.

Can I legally publish a book written by AI? On KDP, yes, with a disclosure if the text was generated and none if you wrote it and used a tool to improve it. I self-publish and went through the definitions in the AI writing generator piece.

Can I sell a book I wrote with ChatGPT? Same answer. The platform's rule is about disclosure, and the distinction it draws is generated versus assisted.

Can you tell if a book is written by AI? Sometimes, by what's missing rather than by what's there. A book with no specific detail, no examples and no numbers reads generated whoever produced it, which is the same test I'd apply to a blog post.

What I'd Buy First

The model, at $17 to $20 a month, and nothing else for the first few months. Everything below it in the stack is free and good.

Then, if the site is publishing weekly and the SEO check is eating an hour each time, one single-seat plan at $49, whichever of the two you find easier to read. Never the three-seat tier. The roundups quote it because they're written by people with three seats, and the price on the page is the price for them.
