The best AI writing assistants, tested and ranked
We gave nine AI writing assistants the same 30 writing tasks and checked every answer. Here's which one writes best, which fits your team or budget, and what each costs.
About this list
An AI writing assistant drafts, rewrites and edits text for you: blog posts, emails, ads and product copy, from a prompt or an outline. Many add brand-voice settings, templates and team features. You'll find all our reviews in the AI writing assistants section and more in our AI writing tools hub.
General chatbots now cover much basic writing, so dedicated tools compete on brand control, how they fit your apps and price. Several have changed what they sell: Rytr now leads with a relationship manager and Jasper sells to enterprise marketing teams. Billing and cancellation complaints are the most common theme in recent user reviews.
To compare them fairly, we ran every tool through the same 30 writing tasks between October 17 and October 23, 2026, and three judges scored the writing without knowing which tool wrote what.

Test results side by side
Two tools pulled clearly ahead. Notion AI had the best raw results: 28 of 30 drafts usable, 0.4 factual errors per 1,000 words and 94 of 100 planted mistakes fixed. Grammarly had 26 usable drafts, 1.1 errors per 1,000 words and 86 fixes, and both got 4.5 out of 5 from our blind judges and 4.5 overall. Grammarly takes first place, and for most buyers its edge is that it works in far more places.
Jasper matched Grammarly's 26 usable drafts, but the judges liked its writing less. After that the gap widened: Rytr had 21 usable drafts and the bottom five 16 to 20, with 3.1 to 3.7 factual errors per 1,000 words. Grammar fixing varied most, from 94 planted mistakes fixed down to 57.
Every tool got the same test, between October 17, 2026 to October 23, 2026.
| Tool | Score | Correct and complete answers out of 30, checked against a written answer key | Factual errors found per 1,000 words | Blind quality score (1–5) from three judges who don't know which tool wrote what | Time to a usable answer, including retries | Cost per month for one person and for a team of five |

Grammarly
Best overallGrammarly came first of nine with 4.5 out of 5. It gave usable answers for 26 of 30 tasks, made just 1.1 factual errors per 1,000 words, fixed 86 of 100 planted grammar mistakes and got 4.5 out of 5 from our blind judges. It scored a full 5 for value for money. Our Grammarly review has the full test.
It began as a grammar checker and now adds AI rewrites, tone changes and agents such as an AI detector and a citation finder, in browsers, desktop, phone, Google Docs and Office. The catch is billing: Pro is $30 a month on monthly billing, and it has 3.1 out of 5 on Trustpilot (10,490 reviews, checked November 2026), with many complaints about surprise charges and cancelling.
Who it's for
Anyone who writes in lots of apps all day and wants proofreading plus light AI rewriting.
Skip it if
You mostly want long AI drafts. Jasper is built for on-brand marketing content.
What we liked
- 26 of 30 answers usable in our test
- Works inline in nearly every app
- Free plan with 100 AI prompts a month
What we didn't
- Fixed 86 of 100 planted mistakes, not all
- $30 a month on monthly billing
- Users report surprise charges and hard cancelling
Key features
- Grammar, spelling and clarity checks on every plan
- Full-sentence rewrites and tone changes on Pro
- Plagiarism and AI-text detection on Pro

Plans and prices

Notion AI
Best for Notion teamsNotion AI came second with 4.5 out of 5 and was the most accurate writer we tested: 28 usable drafts out of 30, only 0.4 factual errors per 1,000 words, 94 of 100 planted mistakes fixed and 4.5 out of 5 from our blind judges. Read our Notion AI review for the detail.
It writes, edits and summarises inside your Notion pages, and its Agent can build pages and databases. Notion says it and its AI providers don't train on customer data by default, and it lists SOC 2 Type 2 and ISO 27001. The limits are the plan and the credits: ongoing AI needs Business at $20 a member a month, and some users found the credits ran out fast. It has 2.2 out of 5 on Trustpilot (441 reviews, checked November 2026).
Who it's for
Teams that already work in Notion and want accurate AI drafts over their own pages.
Skip it if
Your writing happens outside Notion. Grammarly works almost everywhere and has a free plan.
What we liked
- 28 of 30 drafts usable, the best result
- Only 0.4 factual errors per 1,000 words
- Not trained on your data by default
What we didn't

- Credit limits surprise some users
- 2.2 out of 5 on Trustpilot
Key features

Plans and prices

Jasper
Best for marketing teamsJasper came third with an even 4 out of 5. It matched Grammarly with 26 usable drafts out of 30, made 1.4 factual errors per 1,000 words and fixed 87 of 100 planted mistakes, but our blind judges gave its writing 3.9 out of 5. Our Jasper review covers it in full.
Jasper stores brand voices, audiences and product knowledge and applies them to every draft and agent, and its Grid tool adapts campaigns into 27 languages. It is the priciest self-serve tool here: Pro is $69 a seat a month for one user with 2 brand voices. There's no free plan, the 7-day trial turns paid without a reminder, and its terms let it use your inputs to improve its models.
Who it's for
Marketing teams that will set up brand voices and product knowledge and use them across lots of content.
Skip it if
You're one person who wants help writing. Grammarly and Notion AI scored higher for less.
What we liked
- 26 of 30 drafts were usable

| Business Unlimited Brand Voices, Knowledge assets and Audiences; Seat count set with sales. | Custom contact sales |
Rytr
Best on a budgetRytr came fourth with an even 3 out of 5. It gave us 21 usable drafts out of 30, but made 2.6 factual errors per 1,000 words, fixed 68 of 100 planted mistakes and got 2.9 out of 5 from our blind judges. That's fine for quick emails and short pieces. Our Rytr review has more.
Its homepage now leads with Engage, which links your email and calendar to prepare meetings and draft follow-ups; the original writer has more than 40 use cases and 22 tones. The free plan covers 10,000 characters a month and Lite is $9 a month. It has 4.4 out of 5 on Trustpilot (2,449 reviews, checked November 2026), the best here, but subscriptions aren't refunded.
Who it's for
Freelancers and founders who want cheap, quick drafts and follow-up emails and can live with some editing.
Skip it if
Accuracy matters more than price. Grammarly and Notion AI scored much higher and have free plans.
What we liked
- Free plan with 10,000 characters a month
- Unlimited characters from $9 a month
- 4.4 out of 5 on Trustpilot
What we didn't

ContentBot
Best for bulk blog contentContentBot came fifth with 2.5 out of 5. It gave us 19 usable drafts out of 30, made 3.4 factual errors per 1,000 words, fixed 65 of 100 planted mistakes and scored 2.9 out of 5 with our blind judges. Our ContentBot review explains why.
Its strength is volume: Flows produce recurring content, the Importer runs prompts in bulk from a file, posts can go straight to WordPress, and monthly plans include unlimited seats. There's no free plan, and the 7-day money-back offer only applies if you've used under 15% of your credits. It has 3.6 out of 5 on Trustpilot (107 reviews, checked November 2026), mostly from 2023.
Who it's for
Bloggers and agencies who need lots of drafts on a schedule and have time to edit them.
Skip it if
You want copy that needs less checking. Rytr costs the same to start and scored higher.
What we liked
- Flows and bulk Importer for recurring content
- Pay-as-you-go at $0.50 per 1,000 words

| Premium+ 400,000 words a month; Unlimited workflows. | $49 a month |
HIX AI
Best for writing plus slidesHIX AI came sixth with 2.5 out of 5. Only 18 of its 30 drafts were usable, it made 3.7 factual errors per 1,000 words, the most of any tool, and fixed just 57 of 100 planted mistakes. Our blind judges gave it 2.5 out of 5.
It puts chat, an AI writer, an article writer, slides, images, video and research into one credit-based workspace, and a free account gets 20 credits. Paid plans are billed yearly, refunds need a request within 3 days and under 300 credits used, and it has 3.0 out of 5 on Trustpilot (193 reviews, checked November 2026), with complaints about surprise yearly renewals.
Who it's for
Casual writers who want drafts, slides and images in one low-cost place.
Skip it if
You need accurate copy. Rytr costs about the same to start and did better.
What we liked
- Writing, slides, images and research in one place

Nichesss
Best for niche ideasNichesss came seventh with an even 2.5 out of 5. It gave us 20 usable drafts out of 30, but made 3.3 factual errors per 1,000 words, fixed 63 of 100 planted mistakes and got 2.5 out of 5 from our blind judges. Our Nichesss review goes through the test.
It offers more than 150 templates plus a Reddit search that finds subreddits by keyword, handy for spotting niches. Pricing is confusing: the pricing page lists monthly plans from $19 to $99, while the homepage shows a lifetime deal, and long-form writing is only on the $99 Pro plan. The free trial needs no card.
Who it's for
Budget marketers who want quick template copy and Reddit-based niche ideas.
Skip it if
You need good writing. Rytr costs less to start, has a free plan and scored higher.
What we liked
- Reddit search across 40,000+ subreddits

GravityWrite
Best for text, images and videoGravityWrite came eighth with 2 out of 5. It gave us 19 usable drafts out of 30, but our blind judges scored its writing 2.1 out of 5, joint lowest, and it made 3.1 factual errors per 1,000 words and fixed 62 of 100 planted mistakes. Our GravityWrite review has the full story.
It advertises more than 250 tools for blogs, images, video and social scheduling, all paid from one pool of credits, and connects to WordPress, Google Analytics and Ahrefs. Plus is about $8 a month on yearly billing ($97 a year) and Pro is $49 a month. It has 4.2 out of 5 on Trustpilot (568 reviews, checked November 2026), with auto-renewal charges the recurring complaint.
Who it's for
Solo marketers who want text, images and social posts on one budget plan.

Writing quality matters. Rytr scored higher, costs little and has a free plan.

WRITER
Best for large enterprisesWRITER came last of nine with an even 2 out of 5. Only 16 of its 30 drafts were usable, the fewest of any tool, our blind judges gave it 2.1 out of 5, and it made 3.6 factual errors per 1,000 words. Our WRITER review explains the result.
To be fair, it isn't built for the everyday buyer our test reflects. WRITER builds its own Palmyra language models and sells an enterprise platform for writing and agent workflows, with the models available through an API. There are no public prices, only custom quotes, and it has just 2 reviews on Trustpilot.
Who it's for
Large companies with compliance needs that want governed AI on a vendor's own models.
Skip it if
You want good everyday drafts. Grammarly scored far higher and has a free plan.
What we liked
- Builds its own Palmyra models
- Models available through an API
- Agent workflows for enterprise teams
What we didn't
- Fewest usable drafts, 16 of 30
- No public prices
- Almost no public user reviews
Key features

Grammarly, Rytr and HIX AI have free plans, and WRITER publishes no prices. Some Notion prices come from a dated third-party listing because the official page couldn't be read.

Also worth knowing about
We didn't test these tools, but they come up often and may suit a specific need.
ChatGPT
A general AI assistant that several 2026 lists name as the default writing tool, at about 20 USD a month. We haven't tested it.
Claude
A general AI assistant one guide picked for writing quality. We haven't tested it.
QuillBot
A paraphrasing and academic writing tool for rewording existing text. We haven't tested it.
How we tested
Every tool got the same fixed set of 30 everyday writing tasks between October 17 and October 23, 2026, including a blog intro, a product description, an email, a rewrite for tone and grammar fixes on a text with planted mistakes. Prompts were copied in exactly, on the plan most buyers would pick, with no custom instructions. The full set-up is in how we test.
We checked each answer against a written answer key, counted factual errors per 1,000 words and the planted mistakes each tool fixed, and three judges scored the writing from 1 to 5 without knowing which tool wrote what. Each tool then got a score out of 5, in half points, for output quality, accuracy, ease of use, features and limits, and value for money, which together make the overall score.
How to choose
If you write in email, Docs and browsers all day, Grammarly follows you into every app. If your team lives in Notion, Notion AI works over your own pages and was the most accurate tool we tested.
Grammarly is strongest as an editor. For long marketing drafts in a set brand style, Jasper is built for the job, and ContentBot suits bulk blog content you'll edit.
Factual errors ranged from 0.4 per 1,000 words with Notion AI to 3.7 with HIX AI. If you publish without heavy checking, stick with the top three. For sales copy, see our AI copywriting tools list.
Grammarly, Rytr and HIX AI have free plans, so try them on your own writing first. Refund rules vary from none at Rytr to 3 days at HIX AI, so note your renewal date.
None of these is mainly an SEO tool. If ranking in search is the goal, our list of AI SEO writers compares tools built for it.

Frequently asked questions
What is the best AI writing assistant?
In our test, Grammarly came first with 4.5 out of 5. It gave usable answers for 26 of 30 tasks, made 1.1 factual errors per 1,000 words and works in nearly every app. Notion AI also scored 4.5 and was more accurate, so pick it if your team works in Notion.
Are there free AI writing assistants?
Yes. Grammarly's free plan includes grammar checks and 100 AI prompts a month, Rytr's covers 10,000 characters a month and HIX AI gives a free account 20 credits. Notion's free plan only includes an AI trial, and Jasper, ContentBot and WRITER have no free plan.
How much do AI writing assistants cost?
Most start between $9 and $30 a month, billed monthly: Rytr Lite and ContentBot Starter are $9, Nichesss is $19 and Grammarly Pro is $30, or $12 a month billed yearly. Notion AI needs Business at $20 a member a month, Jasper Pro is $69 a seat a month and WRITER sells by quote only.
How did we test these AI writing assistants?
We gave all nine tools the same 30 writing tasks between October 17 and October 23, 2026, with prompts copied in exactly. We counted usable answers against an answer key, factual errors per 1,000 words and planted grammar mistakes fixed, and three judges scored the writing blind.
Do AI writing tools train on my content?
It depends on the tool. Notion says it and its AI providers don't train on customer data by default, and Grammarly lets you opt out in settings. Jasper's terms say your inputs and outputs can be used to improve its models, with an opt-out for EU and UK users. Rytr doesn't say, and HIX AI's policy is unclear.
Can I get a refund on an AI writing assistant?
Terms vary a lot. Rytr doesn't refund subscriptions. HIX AI allows 3 days if you've used under 300 credits, ContentBot 7 days if you've used under 15% of credits, and GravityWrite lists 7 days. Jasper's help center describes 7 days but its terms say no refund, so ask first.
The bottom line
For most people Grammarly is the safest pick, Notion AI is the best choice for Notion teams, and Rytr's free plan suits a tight budget.

If there's a strange new AI tool making its way around the internet, I've probably already bookmarked it. My favorite part is figuring out what these platforms can actually do.
