Visibility in this ranking can be paid for. Payment moves a vendor's position within the
shortlist; it never adds a vendor, and it never changes a word of the review. The largest vendors in AI writing tools
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,
wherever the category has them; the established names follow from place 4 in their ranked order. How it works: placement disclosure ·

The 14 tools, reviewed
#1 neuroflash
German brand-voice content suite with audience twins · Germany · neuroflash.com
Servers in Germany Daily credit meter ISO 27001:2022
neuroflash is the entry a data protection officer will sign fastest. The company is a German GmbH, advertises servers in Germany, holds ISO/IEC 27001:2022 and writes on its pricing page that there is no transfer to third parties and no training of its models with customer data.
- Pricing: Per user / month. Essential is €42 a month and Pro is €84 a month per user, both billed annually plus VAT. Free plan: free trial.
- Best for: European marketing teams with GDPR questions
- Strengths: Editor and ChatFlash; Brand Hub with brand voices; Digital Twins for audience feedback.
Where it falls short
The meter is daily credits, 25,000 on Essential and 250,000 per user on Pro, which caps a heavy day regardless of how quiet the rest of the month was.
Wrong for
A team that needs every prompt to stay on EU soil by contract, since the vendor's own privacy text mentions processing in the USA.

#2 Anyword
Marketing copy with a predicted performance score · United States · anyword.com
Performance prediction 3 seats at $99 7-day trial
Anyword earns its place because it answers the question a marketing team asks after the draft exists: which version should run. The vendor says its prediction picks the better of two variations with 82% accuracy, and scoring is the feature the whole product is organized around.
- Pricing: Flat monthly. Starter is $49 a month, or $39 a month billed yearly, for one seat. Free plan: free trial.
- Best for: Performance marketers testing ad and email copy
- Strengths: Predictive performance score for copy variations; Brand voice, audience profiles and guidelines; Blog Wizard.
Where it falls short
One brand voice is all the two published tiers include.
Wrong for
An editorial team producing long reports or documentation, where a conversion score means nothing.

#3 LanguageTool
Open-core multilingual grammar and rephrasing checker · Germany · languagetool.org
Open source core 30+ languages Team style guide
LanguageTool is the only product here whose core a buyer can read and run. The vendor publishes that core as open source and states that anyone can set up their own LanguageTool server locally or in the cloud, which settles the question of where drafts travel.
- Pricing: Free + paid tiers. Basic is free. Free plan: free plan.
- Best for: Multilingual teams that edit more than they generate
- Strengths: Grammar, punctuation and style checking; AI sentence rephrasing; Team style guide with custom rules.
Where it falls short
It corrects and rephrases; it does not draft a campaign from a brief, so a team after first drafts needs a second product.
Wrong for
A marketing team that wants blog posts and ad variants generated on demand.

#4 Writesonic
SEO and AI-search article platform · United States · writesonic.com
Names its model providers Articles-per-month meter No-card trial
Writesonic gives the most complete answer on this list to the two AI questions a buyer should ask.
- Pricing: Flat monthly. Starter is $79 a month billed annually for 1 user and 15 articles a month. Free plan: free trial.
- Best for: Content teams chasing search and AI citations
- Strengths: AI article generation with monthly quotas; AI visibility tracking across ChatGPT, Gemini and Google AI Overviews; GEO page rewrites with FAQ blocks.
Where it falls short
The meter is articles per month, not words or seats: 15 on Starter, 25 on Basic, 50 on Growth, with one, two and three users respectively. The listed prices are annual-billing prices.
Wrong for
A small team that wants short-form copy, emails or social posts in a brand voice.
Visit Writesonic →
#5 Jasper
Marketing content platform with brand voice and agents · United States · jasper.ai
Per-seat Pro plan Brand Voices and Knowledge 7-day trial
Jasper is organized around a marketing department's work: a Canvas for drafting, agents for research, optimization and translation, and a Jasper IQ layer holding brand voices, knowledge and audiences. Pro is published per seat with a seven-day trial, and the vendor lists SOC 2 among its compliance claims.
- Pricing: Per seat / month. Pro is $69 per seat a month, or $59 a month on annual billing, and includes one seat. Free plan: free trial.
- Best for: Marketing departments standardizing on one writer
- Strengths: Canvas workspace for on-brand drafting; Brand Voices, Knowledge assets and Audiences; Agents for marketing workflows.
Where it falls short
The terms of service say Jasper uses customer inputs and outputs to develop and enhance its own artificial intelligence models, and the right to object is written only for users in the European Union or United Kingdom.
Wrong for
A company whose legal team will not accept a vendor improving its models on submitted drafts.

#6 Grammarly
Writing assistant with metered AI prompts · United States · grammarly.com
Free plan Prompt quota per member Training opt-out in settings
Grammarly is built to be handed to everyone in a company, not only to the people who write for a living.
- Pricing: Free + paid tiers. Free costs nothing and includes 100 AI prompts a month. Free plan: free plan.
- Best for: Whole-company correction and tone checking
- Strengths: Spelling and grammar correction; Tone detection and adjustment; Full-sentence rewrites.
Where it falls short
Training on user content is controlled by a setting the trust page tells users to turn off, called Product Improvement and Training, so the protective choice takes an action.
Wrong for
A content team that needs long-form drafts from a brief, or a buyer who wants no-training as the contractual default instead of a per-user toggle.

#7 Writer
Enterprise AI platform on its own Palmyra models · United States · writer.com
Own Palmyra models Self-hosting option Zero retention by default
Writer removes the usual dependency by owning the model. Its Palmyra family, currently Palmyra X6, is built in house, admins can enable models from other providers, and the vendor lists self-hosting, full data residency and bring-your-own models through AWS Bedrock, Microsoft Azure and NVIDIA NIM.
- Pricing: Quote only. No prices are listed on the plans page: Starter covers up to 5 users with a 14-day free trial and no credit card, and Enterprise is contact sales. Free plan: free trial.
- Best for: Regulated companies needing governed brand writing
- Strengths: WRITER Agent for chat and automation; Playbooks for repeatable work; Team Personality profiles.
Where it falls short
The plans page shows no price for either tier, so budgeting starts with a sales call.
Wrong for
A five-person marketing team that wants to pay by card and start writing this afternoon.

#8 DeepL Write
Rewriting assistant bundled with DeepL Pro · Germany · deepl.com
Add-on to DeepL Pro Six languages Style rules
DeepL Write suits a firm that already routes documents through DeepL and wants the same vendor to tidy the prose. It corrects and rewrites in English, German, French, Spanish, Italian and Portuguese, offers tones and purpose-built styles, and applies company style rules to every suggestion so the guide lives in one place.
- Pricing: Per user / month. Write Pro is an add-on at €6.99 per user a month billed annually, VAT included, on the Individual and Team plans, and is included in Business and Enterprise. Free plan: free trial.
- Best for: Companies already paying for DeepL translation
- Strengths: Corrections and rewrite suggestions; Writing styles for business, academic and casual text; Tone selection.
Where it falls short
It cannot be bought alone: Write Pro rides on a DeepL Pro subscription, and a trial of the add-on is available only while that subscription is itself in trial.
Wrong for
A team with no translation need, which would be buying a translator to get an editor.
Visit DeepL Write →
#9 Frase
SEO article research, drafting and publishing · United States · frase.io
Articles-per-month meter Publishes to WordPress 7-day trial
Frase prices the thing an SEO team counts, articles, and says so on the page: 10 a month on Starter, 40 on Professional, 100 on Scale, each tier with a seven-day trial and a month-to-month option.
- Pricing: Flat monthly. Starter is $39 a month billed yearly or $49 month to month for 1 seat and 10 articles. Free plan: free trial.
- Best for: Small SEO teams publishing weekly articles
- Strengths: Research-backed article drafting; SEO and GEO content scoring; Site audits.
Where it falls short
The operating company is Copysmith AI, Inc. and the about page calls it remote-first without naming a headquarters, so the address comes from the privacy policy alone.
Wrong for
A brand team writing ads, emails and product pages, where article quotas and audit pages are the wrong units.

#10 Surfer
Content scoring and article generation for search · Poland · surferseo.com
Document allowance Google Docs integration Based in Poland
Surfer earns its place with SEO teams that already know what they want to rank for and need a draft measured against what ranks today.
- Pricing: Flat monthly. Listed in euros billed yearly: Discovery €49, Standard €99, Pro €182 and Peace of Mind €299 a month, with Enterprise custom. Free plan: none.
- Best for: SEO teams optimizing pages against competitors
- Strengths: Content scoring and one-click optimization; Create or optimize document allowance; Humanizer and plagiarism checking.
Where it falls short
Neither the regulations nor the general privacy policy we read says which AI providers generate the text or whether customer content is used for training, which leaves a buyer to ask in writing.
Wrong for
A buyer who needs the model provider and training policy in the contract before a pilot.

#11 Copy.ai
Go-to-market workflow platform with a chat plan · United States · copy.ai
5 seats for $29 Workflow credits Choice of three model families
Copy.ai has two very different products under one name. The Chat plan is the simple one: five seats, unlimited words in chat and access to OpenAI, Anthropic and Gemini models for a published $29 a month, which is cheap for a small team that mainly wants model choice.
- Pricing: Flat monthly. Chat is $29 a month, or $24 a month billed annually, for 5 seats. Free plan: none.
- Best for: Sales and marketing ops automating repeat tasks
- Strengths: Chat with OpenAI, Anthropic and Gemini models; Workflows for sales and marketing processes; Brand Voice.
Where it falls short
Above Chat the next step is Growth at $1,000 a month on annual billing for 75 seats and 20K workflow credits, with no tier listed in between.
Wrong for
A ten-person content team that has outgrown chat but does not want a sales-operations platform.

#12 ProWritingAid
Editing toolkit with lifetime license option · United Kingdom · prowritingaid.com
Lifetime license Deletes checked text Teams with SSO
ProWritingAid is the one entry a buyer can pay for once: Premium has a lifetime price alongside monthly and yearly ones. It is an editor's tool that reports on a text and rephrases it, with integrations for Microsoft Word, Google Docs and Scrivener.
- Pricing: Free + paid tiers. Free tier. Free plan: free plan.
- Best for: Long-form writers and small editorial teams
- Strengths: Grammar and line editing reports; AI Rephrases and Sparks; Manuscript and chapter critique.
Where it falls short
The product is built for book authors first: the home page talks about plotting, manuscripts and beta readers, and a marketing team will find no campaign or brand-voice generator.
Wrong for
A marketing department that needs ad copy, landing pages or social posts produced from a brief.

#13 Wordtune
Sentence rewriter and summarizer from AI21 Labs · Israel · wordtune.com
Free tier Rewrites-per-day meter Made by AI21 Labs
Wordtune does one narrow job cheaply: take a sentence and offer better versions of it. The free Basic tier gives ten rewrites and AI suggestions a day plus unlimited spelling and grammar checks, and the Unlimited plan removes the rewrite cap for under ten dollars a month.
- Pricing: Free + paid tiers. Basic is free. Free plan: free plan.
- Best for: Individuals polishing emails and documents
- Strengths: Paraphrasing and rewrite suggestions; Text and video summarization; Grammar and spelling checker.
Where it falls short
The terms give the publisher a perpetual, irrevocable license to copy, store and use user content, including to improve the algorithms underlying the service, and we found no opt-out in the terms or privacy policy.
Wrong for
Any team handling client drafts or unreleased material, given the content license in the terms.

#14 Rytr
Budget template-based copy generator · United States · rytr.me
Free forever tier Character meter Tone match
Rytr is the low-cost end of the category and honest about it: a free tier of 10K characters a month with no card, then an Unlimited plan in single digits.
- Pricing: Free + paid tiers. Free forever with 10K characters a month. Free plan: free plan.
- Best for: Freelancers needing short copy on a budget
- Strengths: 40+ use cases and templates; Tone Match from a writing sample; 20+ pre-programmed tones.
Where it falls short
Neither the terms nor the privacy policy we read names the AI models behind the product or says whether submitted text is used for training, and the terms grant the company a license to use, modify and distribute user content.
Wrong for
A company that must document its AI subprocessors, because the vendor's public pages give it nothing to file.

Questions and answers
What is the best AI writing tool in 2026?
neuroflash ranks first of 14, best for european marketing teams with GDPR questions. Anyword is second (performance marketers testing ad and email copy) and LanguageTool third (multilingual teams that edit more than they generate). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Why not just use a general chat assistant for writing?
For one person writing occasionally, a chat assistant is often enough.
Do AI writing tools train their models on the text we put in?
It depends on the vendor, and the documents differ sharply. Writer, Writesonic, Frase, neuroflash, LanguageTool, ProWritingAid and DeepL (for Pro subscribers) state that customer text is not used for training. Grammarly lets each user turn training off in account settings.
Which of these tools say which AI models they use?
Three. Writesonic's privacy page lists OpenAI, Anthropic, Microsoft Azure OpenAI Service and several others. Copy.ai says its Chat plan gives access to OpenAI, Anthropic and Gemini models.
How are AI writing tools priced?
By almost every unit imaginable.
Who owns the text an AI writing tool produces?
Read the terms, because the answers vary. Writer assigns all right, title and interest in output to the customer, and Writesonic says the customer owns outputs. Jasper claims no ownership of customer property.
Is there a free AI writing tool that is usable for work?
Five of the fourteen have a free plan. LanguageTool's checks up to 2,000 characters per text field with three AI rephrasings a day. Grammarly's includes correction, tone detection and 100 AI prompts a month.
Can any of these tools be self-hosted?
Two vendors say so. LanguageTool publishes its core as open source and states that anyone can set up their own server locally or in the cloud, though the hosted Premium features are a separate paid service.
What is the difference between a brand voice and a style guide in these tools?
A brand voice steers generation: the tool learns tone and vocabulary from samples and writes new text that way, as in Jasper's Brand Voices, Anyword's brand voice or neuroflash's Brand Hub.
Which AI writing tools suit a European company concerned about data location?
Five vendors are outside the United States: neuroflash, LanguageTool and DeepL in Germany, Surfer in Poland and ProWritingAid in the United Kingdom. neuroflash advertises servers in Germany, though its privacy statement also refers to AI queries processed in the USA.
How was this ranking put together?
Every product fact on this page was read on the vendor's own website on the publication date: pricing pages, terms of service, privacy policies, imprints and product pages.
