AI Content Creation Tools for Blogs and SEO, Compared (2026)

AI content creation tools for written content fall into three groups: tools that run a blog for search, general marketing writers, and editing assistants. If you mainly need images, video or social clips, this list isn't for you. It covers words only.

Here's the short list, by who each fits:

1. Inbounder (our product): founders who want search traffic from a planned, linked cluster of blog posts in their voice. 3 articles free, then from $39/mo billed yearly.
2. Jasper: marketing teams writing blogs, email, ads and social in one brand voice. Pro from $59/mo billed yearly.
3. Copy.ai: small teams that want a shared AI chat writer with several seats. Chat plan $24/mo billed yearly for 5 seats.
4. Writesonic: teams that care most about how ChatGPT and Google AI Overviews mention them, with AI articles included. From $79/mo billed yearly.
5. Koala: content and affiliate sites that want long posts in bulk. Starter listed at $25/month.
6. SEOWriting.ai: bloggers who want many SEO articles at a low price. From $14/mo billed yearly for up to 50 articles.
7. Grammarly: anyone who writes the first draft themselves and wants AI help fixing and rewriting it. Free plan; Pro listed at $12/month.

All prices were checked on each vendor's pricing page on November 2, 2026.

• "AI content creation" covers very different jobs. Decide first whether you need a blog that ranks, copy for every channel, or help editing your own writing.
• For search traffic, a tool that plans linked posts around one topic does more than one that writes on request.
• For copy across email, ads and social, a general marketing writer like Jasper or Copy.ai fits better.
• Entry prices for the written-content tools here run from $14 to $79 a month billed yearly.
• Read every AI draft before it goes out. Product facts and competitor claims are where AI tools slip most.

We kept only tools that create written content, and we checked each vendor's own pricing page on November 2, 2026. This is a comparison of plans and stated features, not a hands-on test of output quality. For each tool we asked:

1. Job: is it built for blog SEO, marketing copy in general, or editing?
2. Brand voice: can it learn how your company sounds?
3. Planning and links: does it decide what to write and link posts together?
4. Price: what the entry plan costs, and what it includes.

1. Inbounder: a blog that's planned for search

Inbounder is our product, so weigh this one accordingly. You paste your site's URL, and it builds a brand-voice profile from your pages, researches keywords and plans a pillar-first cluster: one broad pillar post and supporting posts that link to it. Planning, keyword research and brand voice cost nothing on any plan.

Each article is written in your voice, linked to its pillar and siblings, and given a featured image. You review every article before it goes anywhere. Paid plans send drafts to WordPress in one click, and Inbounder connects to Search Console. If you work in Claude or Cursor, you can also run Inbounder from your AI agent.

Good fit if: your goal is search traffic from a blog and you'd rather approve posts than plan them. Not a fit if: you need ad copy, email or social posts more than blog posts.

2. Jasper: one voice across every channel

Jasper is a general marketing writer. Pro is $59/mo billed yearly ($69 monthly) for 1 seat, with 2 Brand Voices, 5 Knowledge assets and 3 Audiences, and a 7-day free trial. A browser extension for Chrome and Edge brings it into the tools you already use. Business is custom-priced. Planning a blog for search is left to you or other tools; the Inbounder vs Jasper comparison covers that difference job by job.

Good fit if: your team writes across email, ads, social and the blog, and a consistent voice matters most. Not a fit if: blog SEO is most of what you need.

3. Copy.ai: shared chat writing for a small team

Copy.ai's Chat plan is $24/mo billed yearly ($288/yr) or $29 billed monthly, for 5 seats with unlimited words in chat and access to OpenAI, Anthropic and Gemini models. Larger plans add workflow credits for multi-step tasks and start at $1,000/mo billed yearly. If you're leaving it for long-form SEO, see our Copy.ai alternatives guide.

Good fit if: several people need an AI chat writer for everyday marketing copy. Not a fit if: you want finished, linked blog posts without prompting each one.

4. Writesonic: content plus AI-search tracking

Writesonic's Starter is $79/mo billed yearly. It tracks your brand across ChatGPT, Gemini and Google AI Overviews and includes 15 AI articles a month, 10 site audits and 1 Writing Style (its brand voice feature), with WordPress among its integrations. The Inbounder vs Writesonic comparison covers the difference in focus.

Good fit if: your first question is how AI answers describe your brand. Not a fit if: you mainly want blog posts at a lower price.

5. Koala: long posts in bulk

Koala's Starter is listed at $25/month for 45,000 words, with real-time factual data, live Amazon data for affiliate articles, bulk writing and publishing to WordPress, Shopify, Webflow and Ghost. Professional ($49/month) adds KoalaLinks internal linking and a Search Console and Analytics dashboard. A free tier includes 5,000 words.

Good fit if: you run a content or affiliate site and want many long posts. Not a fit if: you want the tool to plan a topic cluster first.

6. SEOWriting.ai: the lowest cost per article

SEOWriting.ai's Starter is $14/mo billed yearly ($19 monthly) for up to 50 articles, with 1 brand voice, internal linking for 500 URLs per site and a WordPress integration. You can write 3 articles free without payment details.

Good fit if: you know your topics and want SEO articles cheaply. Not a fit if: you want the tool to decide what to write and how posts connect.

7. Grammarly: help with what you write yourself

Grammarly isn't a blog writer. It checks and rewrites what you've written. The free plan covers spelling, grammar, tone and 100 AI prompts a month. Pro is listed at $12/month and adds full-sentence rewrites, plagiarism and AI-text detection and 2,000 AI prompts a month.

Good fit if: you or your team write the drafts and want them cleaner. Not a fit if: you want the tool to produce the content for you.

Match the tool to the job:

• "We need search traffic from our blog." Inbounder, or SEOWriting.ai or Koala if you'll plan topics yourself. Our best AI blog writers guide goes deeper on this group.
• "We write for every channel." Jasper, or Copy.ai for a small team on a budget.
• "We care most about AI answers." Writesonic.
• "We write; we need editing help." Grammarly.

If your main need is long, single articles rather than a whole blog, the AI article writer guide compares tools on that job. And if you want to automate the steps around the writing, automated content creation explains what's safe to hand over. All of our AI content guides are collected on the AI content hub.

The tool matters less than three habits. Each piece should answer one question, and answer it early. Related posts should link to each other and to one pillar page, so search engines see a topic covered in depth. And a person should check facts, prices and claims before anything goes live. The SEO-focused tools here help with the first two; the third is yours.
