Every AI writing tool's sales page says roughly the same thing: drafts in your voice, more content, less effort. Read three in a row and they blur together. The only sure way to find out which one fits looks like paying for a month, and by then your product notes are in it and the habit is built.
The takeaway up front: don't choose an AI writing tool for your business in general. Pick one writing job you repeat every week, judge each tool only on that job, and give it a one-week trial on real work before the paid plan renews. The five checks below (voice, facts, data, plan limits and the trial itself) work for any tool and need no technical knowledge.
For the shortlist step, this guide leans on Eric Salo Reviews, which writes short, first-person reviews of online tools, software, courses and services; its AI coverage takes in prompt builders and AI writing and content tools. The shortlist section below explains where it fits and where it doesn't.
Disclosure: This guide was written in collaboration with Eric Salo Reviews, and it names no AI writing product.
Why the sales pages all sound alike
They describe the same visible thing: a box where you type a request and get text back. What matters to a small business sits elsewhere: whether the tool keeps your voice on the third draft, what it does with the customer details you paste in, how many words your plan allows, and what you keep when you leave. That lives in the settings, the privacy policy and the plan terms.
So "which AI writing software is good?" has no useful answer. "Which tool drafts our weekly email to past customers well enough to send after light edits?" does, because you can check it.
Step 1: Pick one recurring writing job
A good first job repeats on a schedule, follows the same shape each time, and is quick to check before it goes out. It's the reasoning our guide to what to automate first in a small business applies to any task: frequent, rule-stable and loud when it breaks. Four jobs make good first candidates.
Product or service descriptions
They share a structure the tool can follow, but the facts must be exact: sizes, materials, what's included. Supply every fact yourself and this is a strong first job.
A weekly customer email
The same shape each week, and voice matters most here, because the readers already know you. If you have repeat customers, the small business digital marketing guide explains why email is the channel to start with.
Social captions
Short and low-stakes per post. The risk is sameness: after a month, every caption opens the same way.
Replies to common enquiries
The highest stakes of the four. A wrong answer about a price, a delivery date or a refund goes straight to a customer. Start here only if a person reads every reply before it's sent.
Pick the job you'd most like off your desk and can check fastest, then write it in one sentence: "The tool drafts our Friday email to past customers from my bullet notes." That sentence is the yardstick for every check below.
Five checks for an AI writing tool for small business use
1. Voice control: does it give your voice back?
Give the tool three to five pieces you've written for the job, your one-sentence job and this week's facts, and ask for the next one. Does it keep your sentence length, your words, your sign-off, or drift into stock phrases you'd never use?
Some tools save examples as a style profile or reusable brief, and a standalone prompt builder does a similar job by storing a structured request. Either way, check that the second and third drafts still sound like you without explaining it all again. A brief this short is enough:
Job: weekly email to past customers
Voice: match the three examples below; short sentences; no exclamation marks
Facts to use (and no others): [this week's notes]
Never: invent prices, dates, discounts or quotes
2. Fact handling: plan the human check
An AI content tool will state things you never told it, in the same confident tone as the things you did. NIST's Generative AI Profile calls this confabulation: "the production of confidently stated but erroneous or false content (known colloquially as 'hallucinations' or 'fabrications') by which users may be misled or deceived." It adds that such falsehoods are "most commonly a problem for text-based outputs", which is what a writing tool produces.
No setting removes it. Put every fact in the brief, tell the tool to use only those, and have one person read each draft against the source: prices, dates, names, policy terms and any claim about what a product does. During the trial, note every fact the tool added on its own. A tool that adds fewer fits better, but no tool lets you skip the read-through.
3. What happens to the text and customer details you paste in
Before pasting a customer's email or order details, find these answers in the vendor's privacy policy and terms, not on the sales page:
- Is what you type stored, and for how long?
- Is it used to train the vendor's models, and can you switch that off?
- Can you delete your history and account data?
- If you add users, who sees what the others wrote?
The same NIST profile lists data privacy among the risks of generative AI, including leakage and unauthorised use or disclosure of personal information. If an answer isn't in writing, treat it as a no, and strip names, addresses and order numbers from anything you paste until you have it.
4. Plan limits and the exit
Check the monthly word or credit allowance and what happens when you reach it, whether the trial includes the features of the plan you'd buy, how many users it covers, and when it renews. Then check the way out: can you export what you made in a usable format, and what do you keep after cancelling, such as drafts, saved briefs and style profiles? Put the renewal date in your calendar the day you sign up.
5. A one-week trial on real work
Run the trial on the job you wrote down, with real notes and a real deadline, and compare it with what you write now. The log below is the whole method.
The seven-day trial log
Fill one row a day, on the two tools from your shortlist (see 'Building the shortlist' below), one after the other.
| Day | Do this | Write down |
|---|---|---|
| 1 | Write the one-sentence job. Gather three to five past examples and this week's facts. Draft one piece yourself. | How long your own draft took and what you'd still change. |
| 2 | Give the tool the examples, the job and the facts. Ask for the same piece. | Every edit before you'd send it. Every fact it added that you never supplied. |
| 3 | Ask for the next piece without explaining your voice again. | Whether it still sounds like you, and which phrases you removed. |
| 4 | Give it an awkward case: a complaint, a product with a catch, a policy exception. | Where it guessed, softened the facts or promised something you don't offer. |
| 5 | Read the privacy policy, training setting, deletion options and user permissions. | Each answer, with a link to the vendor page. |
| 6 | Export everything you made and read the cancellation terms. | What you keep, and the renewal date. |
| 7 | Put the tool's drafts from days 2 to 4 next to your own from day 1. | Keep, switch or stop, and the reason in one line. |
Illustrative example: a two-person bakery runs the log on its Friday email. By day 3 the drafts sound like the owner. On day 4 the tool's draft tells customers the shop is open on a holiday it was never told about, and the owner catches it before sending. The bakery keeps the tool and adds one line to its brief: open days come only from the notes.
A neutral yardstick when the vendor's page is the only source
If you want a reference that doesn't come from anyone selling a tool, NIST's AI Risk Management Framework, a voluntary framework released in January 2023, is one neutral checklist for judging an AI product's trustworthiness. NIST describes it as "intended for voluntary use and to improve the ability to incorporate trustworthiness considerations into the design, development, use, and evaluation of AI products, services, and systems."
It covers the whole life of an AI system, from design and development to use and evaluation, so a small business that only uses a writing tool won't work through all of it. The habit worth taking from it is to ask about risk before features: what could go wrong in your one writing job, who would notice, and how fast.
Building the shortlist: where AI tool reviews fit
A trial takes a week per tool, so only two tools should get one. The shortlist decides which two.
Eric Salo Reviews publishes short, first-person reviews that say what a product is, who it suits and what stands out, with a link to the product. Its founder and primary author is Eric Salo. On the AI side, the kinds of tool range from prompt builders and AI writing and content tools to chatbots and sales assistants, video creators, product-image tools and customer-support software, and an overview sits on its AI tool reviews page.
The reason to use it here is the part of a review that says who the product suits. Hold each AI writing tool review against your one-sentence job and drop any tool whose stated fit is a different job, before you pay for a trial. The reviews are aimed at people building an online business who are weighing a tool, course or service: bloggers, creators, affiliate marketers and small online sellers. If you sell online, that overlaps with you; if your job is replies to local enquiries, read what each review says about who the product suits with that difference in mind.
The trade-off: the reviews are short and carry affiliate links. Don't rely on any review for plan limits, privacy or cancellation terms: those live on the vendor's own pages. Take your two remaining tools there for checks 3 and 4, then run the log.
FAQ
Is AI-written text safe to publish without editing?
No. Treat every draft as unchecked until a person has read it against your own facts. NIST's Generative AI Profile describes confident but false output as a known risk of these systems, and a wrong price or policy line in a customer email is your mistake, not the tool's.
Which writing job should I start with?
The one you repeat most often, that follows the same shape each time, and that you can check fastest. Product descriptions and a weekly customer email are usually easier first jobs than enquiry replies, because you can check a whole piece at your desk before it goes out, while a reply goes straight to one customer who is waiting for it.
Does Eric Salo Reviews use affiliate links for the AI tools it covers?
Some of them, yes. In the site's own disclosure, Eric Salo Reviews states that some of its links are affiliate links: it may earn a commission at no extra cost to you when you buy through one. Confirm plan terms, privacy and cancellation on the vendor's own pages either way, as checks 3 and 4 ask.
What should I never paste into an AI writing tool?
Customer names, addresses, order or payment details, and anything a customer told you in confidence, unless the vendor's terms say how it's stored, whether it trains models and how you delete it. Strip identifying details from your examples first.
