Which AI content writing tool to start with
For most work writing, one assistant and one checker are enough to start. Begin with the writing you do most.
Start with one general assistant
Claude and ChatGPT both draft, rewrite and summarize, and both have free plans. One of them covers most everyday writing, from emails to long articles. Add a specialist only for a job it doesn't cover well.
Add a specialist for one kind of writing
Surfer SEO drafts articles built to rank in search, and Sudowrite is made for fiction. For ads, AdCreative.ai writes headlines and text alongside the visuals.
Keep a grammar checker running as you type
QuillBot and Grammarly check grammar and spelling in your browser and other apps on their free plans. Grammarly's Pro plan adds tone adjustments. QuillBot's free plan also includes a paraphraser and a citation generator.
Use the free plan before you pay
Claude, QuillBot, Grammarly and Pangram are free to start, and HubSpot's AI Content Writer is free inside HubSpot. Jasper, Surfer SEO and AdCreative.ai offer seven-day trials instead. Test each one on a real piece of your own writing.
AI content writing tools FAQ
What are AI content writing tools?
AI content writing tools are apps that draft, rewrite or check written content, from blog posts and emails to ads and novels. Claude, for example, drafts and edits long pieces, while QuillBot checks grammar as you write. We group them by job: AI writers, copywriting tools and grammar checkers. Each card on this page leads with our pick for one job and links to the full list.
What is the best AI content writing tool in 2026?
Claude is our top-rated AI content writing tool as of October 2026, at 4.8 out of 5, for drafting and editing long pieces in a natural voice. ChatGPT shares that score, but we don't have a full review of it. HubSpot leads copywriting at 4.6 for teams that market in HubSpot, and QuillBot and Grammarly share our top grammar-checker score at 4.3.
Are there free AI content writing tools?
Yes, several of our top picks are free to start. Claude has a free plan that runs on its Sonnet and Haiku models, and ChatGPT's free plan includes unlimited text chats. QuillBot checks grammar for free and paraphrases texts of up to 125 words. Grammarly's free plan fixes basic errors and includes 100 AI prompts a month, and HubSpot's AI Content Writer is free inside HubSpot.
What is the difference between an AI writer and a copywriting tool?
An AI writer such as Claude drafts many kinds of text, while a copywriting tool is built for marketing copy that has to sell. AdCreative.ai, for example, writes ad headlines and scores them alongside the ad visuals, and Jasper keeps a team's copy in one brand voice. You can pair a general AI writer for drafts with a copywriting tool for ads and campaigns.
Can I check whether a text was written with AI?
Yes. Pangram estimates how much of a document was written or edited with AI and highlights the AI-edited parts. QuillBot includes a free AI detector, and Grammarly adds AI detection on its Pro plan. Treat a detector's score as a reason to look closer rather than as proof, and read the flagged passages yourself.
How are the tools on this page chosen?
Each card shows the highest-rated tool we have reviewed for one job, such as Claude for AI writers, then the next tools by rating. Claude also tops our copywriting list, so HubSpot, next by rating, leads that card. Every rating is our overall score on a 5-point scale. Our method is on the page about how we test and rate tools.

About this page
- What is listed
- The AI content writing tools we have reviewed, one card for each kind of tool: AI writers, copywriting tools and grammar checkers. Each card links to the full list for that job, which also includes tools we list without a full review, such as ChatGPT and LanguageTool. AI video, image and voice tools have their own categories.
- How tools are chosen
- Each card leads with our top-rated pick for that job, then the next tools by rating. A tool leads one card only. Claude (4.8) tops both AI writers and copywriting, so it leads AI writers and HubSpot (4.6) leads copywriting. Only tools with a full review appear on the cards, so ChatGPT, which shares Claude's 4.8, is listed on the AI writers page instead. Best overall is the highest-rated tool on the page. Each "Skip it if" line comes from our review of that tool.
- Ratings
- Each rating is our current overall score for the tool, on a 5-point scale, rechecked between 14 and 18 October 2026. A score rates the whole product, so a broad platform can sit above a dedicated app. Tools with the same rating are rated equally: QuillBot and Grammarly share 4.3, and the order between them is not a ranking. See how we test and rate tools.
- Prices
- The lowest paid plan, read from each vendor's own pricing page between 16 and 18 October 2026. Where a card says "billed yearly", the price is the rate on annual billing, and paying month by month costs more. HubSpot's $20 Starter price is per seat, billed monthly, and HubSpot shows a limited new-customer offer beside it.
- Update log
- 18 October 2026: new layout with one card for each job. Every rating, price and free plan rechecked.
