AI writing tools can save hours on first drafts, emails, product descriptions and blog outlines. They are not all built for the same job, though. Some focus on grammar and clarity, some on marketing copy, and a growing number now focus on SEO and visibility in AI search results.

This guide compares 10 popular AI writing tools: what each one does, who it fits, what the free option looks like, and where paid plans start. Prices were checked on each company’s official website in September 2026 and can change at any time, so always confirm on the vendor’s pricing page before you buy.

AI writing tools: quick comparison

How we chose these AI writing tools

We started with the AI writing tools our readers ask about most, then checked each product’s official website for its current focus, plan names, free option and entry price. We describe what each vendor says its product does and add practical notes on who it suits. We do not accept payment for placement in this list. See our review methodology for details.

1. Grammarly

Grammarly checks spelling, grammar, clarity and tone as you type in the browser, email, documents and many desktop apps. The free plan covers basic error detection and includes a limited number of AI prompts each month. The Pro plan adds full-sentence rewrites, tone adjustments, plagiarism checks and AI-text detection, plus a larger monthly allowance of AI prompts.

• Good fit if: you write a lot of emails, reports or client messages and want cleaner writing without changing tools.
• Keep in mind: it improves writing you already have more than it creates long articles from scratch.

2. QuillBot

QuillBot started as a paraphrasing tool and now bundles a grammar checker, summarizer, citation generator, translator, AI detector and plagiarism checker. According to QuillBot, many of its tools are free to use, while the paraphraser and grammar checker have usage limits on the free tier. Premium is sold monthly ($19.95), every three months, or yearly ($99.95, about $8.33 per month).

• Good fit if: you are a student, researcher or blogger who rewrites and summarizes existing text.
• Keep in mind: paraphrasing does not make content original. Always add your own insight and cite sources.

3. Rytr

Rytr is a budget-friendly assistant for short content such as social posts, product descriptions, email drafts and ad ideas. Its free plan includes 10,000 characters per month. The Unlimited plan removes the generation cap and adds plagiarism checks, and the Premium plan adds more languages, multiple tone matches and a Chrome extension.

• Good fit if: you are a solo creator who needs quick short-form drafts at a low monthly cost.
• Keep in mind: long articles will need heavy editing and fact-checking.

4. Jasper

Jasper is an AI marketing platform built around brand consistency. Teams can store Brand Voices, knowledge assets and audience profiles so drafts follow the company’s style instead of sounding generic. The Pro plan includes one seat, marketing agents and the Canvas workspace. The Business plan adds unlimited seats, custom agents, API access and enterprise controls at custom pricing. Jasper offers a 7-day free trial of Pro but no free plan.

• Good fit if: you run marketing for a brand and need many assets that sound the same across channels.
• Keep in mind: adding more users on Pro requires moving to the Business plan.

5. Copy.ai

Copy.ai now positions itself as an AI platform for go-to-market (GTM) teams. Beyond content drafts, it offers Workflows that automate repeatable sales and marketing tasks such as lead research, prospecting emails and CRM enrichment, plus a Brand Voice feature. The Chat plan is the entry point; the Growth, Expansion and Scale plans are aimed at larger teams that run automated workflows at volume.

• Good fit if: you want to automate parts of your sales or marketing process, not just write copy.
• Keep in mind: the workflow plans are priced for companies, not individual creators.

6. Koala AI

Koala AI (KoalaWriter) focuses on long-form, SEO-oriented blog articles. New accounts receive free trial words and credits without a credit card, and paid plans are based on monthly credits, starting with the Starter plan. Annual billing is about 20% cheaper, according to Koala’s pricing page.

• Good fit if: you publish blog content regularly and want structured first drafts faster.
• Keep in mind: Google rewards helpful, original content. Treat AI drafts as a starting point and add first-hand experience, examples and accurate data.

7. Frase

Frase describes itself as a content operating system for AI search. It helps you research topics, build content briefs, write, optimize for Google rankings and monitor whether AI tools cite your pages. Plans range from Starter (one seat, one site) to Professional, Scale and Enterprise. All plans come with a 7-day free trial that does not require a credit card.

• Good fit if: you manage a content site and want research, briefs and optimization in one place.
• Keep in mind: article limits per month vary by plan, so match the plan to your publishing schedule.

8. Surfer

Surfer (Surfer SEO) is best known for its Content Editor, which scores a draft against the pages already ranking for a keyword and suggests terms, headings and length. It has also added AI search analytics. Surfer lists several plans, from Discovery to Enterprise, and offers a free way to start before you commit to a paid subscription.

• Good fit if: SEO traffic is your main goal and you want data-driven guidance while you write.
• Keep in mind: a high content score does not guarantee rankings. Quality and usefulness still come first.

9. Writesonic

Writesonic began as an AI writer but its current focus, according to its website, is AI search visibility. It tracks how often your brand appears in answers from AI platforms such as ChatGPT, Gemini and Google AI Overviews, finds content gaps and helps you fix them with site audits and AI-generated articles. All plans include a free trial with no credit card required.

• Good fit if: you are a brand or agency that wants to measure and grow visibility in AI answers.
• Keep in mind: the entry price is higher than simple writing assistants because it is a monitoring platform.

10. WRITER

WRITER is an enterprise AI platform for teams that need AI content and agent workflows with governance, brand rules and compliance controls. The Starter plan targets small teams of up to five users and comes with a 14-day free trial. The Enterprise plan adds unlimited users, a full Knowledge Graph and security certifications, with custom pricing.

• Good fit if: your company works in a regulated industry or needs strict control over AI output.
• Keep in mind: it is more than most freelancers and small blogs need.

How to choose between AI writing tools

• Define the job first. AI writing tools fall into four groups: editing and grammar (Grammarly, QuillBot), short copy (Rytr, Copy.ai), brand marketing (Jasper, WRITER), or SEO content (Koala, Frase, Surfer, Writesonic).
• Start with the free plan or trial. Test it on a real task from your week, not a demo prompt.
• Check the limits. Characters, credits, articles, seats and sites per plan often matter more than the headline price.
• Review data and privacy terms. Confirm how the vendor stores and uses what you paste into the tool, especially client data.
• Keep a human in the loop. Fact-check claims, add your own experience and edit for your audience before publishing.

Using AI writing tools responsibly

AI writing tools are most useful when a person stays in charge. Google’s guidance focuses on whether content is helpful and reliable, not on how it was produced. Mass-producing pages mainly to rank can be treated as spam. The safest approach is to use AI to speed up research and drafts, then add original insight, accurate sources and a clear author. If you publish on a site with ads, also make sure every page offers real value to readers.

Frequently asked questions

Which AI writing tools have the best free plans?

For everyday editing, Grammarly and QuillBot offer useful free tiers. For generating short copy, Rytr’s free plan includes 10,000 characters per month. The right choice depends on the task.

Is content from AI writing tools bad for SEO?

Not by itself. Search engines look at quality and usefulness. Content created only to manipulate rankings can hurt a site. Edit, fact-check and add original value to every AI draft.

Can I use AI writing tools for client work?

Usually yes, but check each tool’s terms of service about content ownership and data use, and tell clients if your agreement requires it.

Do I need an SEO tool as well as AI writing tools?

Not always. Tools like Frase and Surfer combine SEO guidance with writing features, while Grammarly works well alongside any of them for final editing.

How often do prices for AI writing tools change?

Often. SaaS companies update plans several times a year. We note the month we checked, and you should confirm the current price on the official pricing page.
