Best AI SEO Writing Tools (2026): 7 Picks From $39/mo

The best AI SEO writing tools: Mentionova, Frase, Surfer, Writesonic, Clearscope, AirOps and MarketMuse, with official prices, limits and article counts.

By Marcus Reed, Go-to-Market Editor Updated November 4, 2026 Prices checked on official vendor pages November 4, 2026

The best AI SEO writing tool for 2026 is Mentionova, at $99 a month billed annually: pick it if you want articles researched from the live results page and real sources, every statistic linked, and briefs aimed at the AI answers where you’re missing; skip it if you only need a content grade inside Google Docs, in which case Surfer or Clearscope is the simpler buy. AI writing for SEO has split in two. Some tools score a draft against what ranks on Google. Others research, write and refresh pages so they get cited by ChatGPT, Perplexity and Google AI Overviews as well. We compared seven tools on both jobs. Every price, limit and feature comes from the vendor’s own pricing or product page, fetched November 4, 2026.

Mentionova

Mentionova is an AI visibility platform whose agents write and refresh content for the prompts where you’re missing.

Best for

Teams that want AI writing tied to measurement: the tool finds the AI answers that cite a rival instead of you, then drafts the page or refresh that closes the gap.

What each plan includes

PlanPrice (yearly / monthly)Limits
Starter$99 / $125100 agentic tasks, 25 prompts, 3 engines
Scale$320 / $400500 tasks, 100 prompts, 6 engines
Enterprise$799 / $9992,500 tasks, 250 prompts, 6 engines

Source: mentionova.com/pricing, fetched November 4, 2026.

The AI content writer reads the live results page and real sources first, writes a research brief, then writes the article in your brand voice. Every statistic links to its source, and nothing publishes until you approve the draft. The content optimizer pulls 90 days of Search Console data for each page that is losing clicks, checks which sources AI engines cite instead, reads the live results page and drafts a refresh brief per page.

What else the writer works with

ToolWhat it does
Content gap analysisFinds prompts where a rival is named, not you
Keyword clusteringSeed topic to pillar-and-spoke plan
Internal linkingFinds orphan pages, suggests anchors
Schema generatorArticle, BreadcrumbList and FAQPage JSON-LD
Content gridDrafts, citation checks, brand-voice tests

Source: Mentionova product pages (content gap analysis, keyword clustering, schema markup generator), fetched November 4, 2026.

Content gap analysis collects every prompt where an AI engine names a competitor and not you, across six engines, groups them into topics and names the page that would close each gap: a new guide or a refresh of one you have. The keyword clustering template reads what Google ranks for a seed topic and returns a pillar page with its spokes, at about 13 tasks a run. The internal linking tool reads your sitemap, finds pages nothing links to and stages the anchor and sentence for review.

Limits

Writing runs on agentic tasks. The How-To Guide grid shown on Mentionova’s writer page uses about 28 tasks per article, so Starter’s 100 tasks cover a few articles a month alongside tracking.

The pricing catch

Starter tracks three engines (ChatGPT, Perplexity and Google). Claude, Gemini and Reddit need Scale at $320 a month billed annually.

Who should skip it

Teams that want unlimited bulk articles with no research step. See Mentionova pricing and our Mentionova alternatives.

Frase

Frase is an SEO and GEO content agent that researches, writes and publishes, and now tracks AI visibility.

Best for

Small teams that want a low-cost writer that can publish straight to their CMS.

What each plan includes

PlanPrice (yearly / monthly)Key limits
Starter$39 / $491 seat, 10 articles, 20 prompts
Professional$103 / $1293 seats, 40 articles, 50 prompts
Scale$239 / $2995 seats, 100 articles, 75 prompts

Source: frase.io/pricing, fetched November 4, 2026.

The agent drafts and auto-publishes on every plan when you switch it on, to WordPress, Webflow, Sanity, Wix or FraseCMS. Every plan has a 7-day free trial with no card.

Limits

Starter’s AI Visibility covers ChatGPT and Google AI only. Professional adds Perplexity; Scale adds Claude and Gemini.

The pricing catch

Writesonic

Limits

Paid tiers track ChatGPT, Gemini and Google AI Overviews; all 9 platforms need Enterprise.

The pricing catch

Who should skip it

Teams that need Perplexity or Claude tracking on a self-serve plan. See Writesonic alternatives.

Who should skip it

Teams that need finished drafts rather than briefs.

What makes AI-written content get cited?

Three patterns show up across the vendor pages we read. First, research before writing: Mentionova reads the live results page and sources before drafting, Writesonic runs SERP and competitor analysis first, and Frase pairs research with its writer. Second, sourced facts: Mentionova links every statistic to its source, and Writesonic says every claim is backed by a first-party source before publish. Third, refreshes: Mentionova’s optimizer and Frase’s Content Guard both watch pages that lose traffic and propose the fix, because a page that slips on Google usually slips in AI answers too. Our AI search statistics show how much of discovery has moved to these engines.

How to choose an AI SEO writing tool

Decide whether you need a writer or an editor

Writers (Mentionova, Frase, Writesonic, AirOps) produce drafts. Editors (Surfer, Clearscope) grade drafts your team writes. MarketMuse plans topics.

Check where the facts come from

AI engines cite pages with specific, sourced facts. Prefer tools that research live sources before writing and link every statistic, as Mentionova and Writesonic describe.

Tie writing to measurement

A writer that also tracks AI answers can tell you which page to write next. Mentionova, Frase and Writesonic do both; Surfer and Clearscope add tracking to an editor.

Count articles, not just price

Frase Starter includes 10 articles for $39 a month billed yearly; Writesonic Starter includes 15 for $79. Mentionova prices by agentic tasks instead.

Frequently asked questions

What is the best AI SEO writing tool?

Mentionova is our top pick. Its writer reads the live results page and real sources before drafting, links every statistic, and targets the AI answers where a competitor is cited instead of you. Starter is $99 a month billed annually.

What is the cheapest AI SEO writing tool?

Frase Starter at $39 a month billed yearly ($49 monthly) for 10 articles a month. MarketMuse has a free plan, but it plans topics rather than writing articles.

Yes, when it is researched and specific. The tools that aim for both, such as Mentionova and Writesonic, research the results page and sources before writing and cite their facts.

How many articles does Writesonic include?

Does Frase publish automatically?

Yes. The Frase agent can draft and auto-publish on every plan to WordPress, Webflow, Sanity, Wix or FraseCMS when you switch it on.

How does Mentionova price AI writing?

No. AirOps lists Solo, Pro and Enterprise without list prices. Solo includes 35,000 tasks and charges $0.025 for each extra task.

Should I use an AI writer or an AI visibility tool?

Both, ideally in one plan. A tracker shows which AI answers you're missing; a writer closes the gap. Mentionova, Frase and Writesonic combine the two.
