The best services that write content AI assistants cite, in our ranking, are ItGrows, Discovered Labs, Siege Media, Animalz, Frase, Writesonic and Surfer. The first four do the work for you; the last three are AI writing tools with AI-search tracking that your own team runs.
ItGrows is our product, and we rank it first; here is how we ranked the rest. Every detail about the other six comes from the provider's own website, opened in November 2026 and linked.
How did we rank these content services?
An assistant can cite only pages it can find and read. So we checked each provider on its own website in November 2026 against five things a content service for AI search has to deliver:
- Written and published for you, on your own site. The provider writes the pages, and they live on your domain, not the provider's.
- One page per buyer question, answer first. Each page answers one buyer question in its opening lines, with specific facts, their sources and your own data. Our explainer on answer engine optimization covers what that work consists of, from picking buyer questions to publishing useful pages.
- Pages crawlers can read. The provider checks that crawlers can reach what it publishes.
- The same buyer questions checked before and after. Your questions go to ChatGPT, Claude, Gemini and Perplexity before the work starts and again after.
- A published price and term. You know the cost and the commitment before the first call.
We give no scores, weights or stars. The order follows how much of this each provider publishes on its own site, so services that write for you come before tools your own team runs.
Which services write content that AI assistants cite?
1. ItGrows (our product)
ItGrows is the strongest choice when you want someone else to do the work on your own website and measure it on your own buyer questions. It does the work on your site so that ChatGPT, Claude, Gemini and Perplexity can find and cite it. Every two weeks it puts your buyer questions to all four assistants and counts the answers that name you and the sites they cite.
It publishes articles on your own domain, not on ours: in our measurement of 20 October 2026, Perplexity cited an article we had published on a client's site, a German company-formation advisory.
The price is public on our homepage: $499 a month, month to month, plus a one-time $499 setup; the setup is free with $1,497 for 3 months upfront or $4,788 for a year ($399 a month, 20% off). Every paid plan carries our growth guarantee, with its conditions written in our terms: "In 90 days, AI assistants will name you more often than on launch day — or we work for free." The detailed report, 20 buyer questions across all four assistants, is free with an account; here is a real one.
Best for: owners who want articles published on their own site, all four assistants measured every two weeks, and the price and guarantee settled before they sign.
2. Discovered Labs
Discovered Labs runs AEO and SEO as month-to-month retainers. Its pricing page says every retainer includes an AI visibility audit using its own tracker, fully handled editorial (roadmaps, content created and edited using CITABLE, schema, metadata and internal linking) and monthly reporting benchmarked against competitors. The Establish tier covers up to 20 content units a month, where a blog post or a refresh is one unit, plus a one-off technical audit of indexation, crawlability, performance and structured data. It costs €6,995 a month on a six-month commitment or €7,995 month to month, as of November 2026. A one-off diagnostic across Google, ChatGPT, Claude, Perplexity, Gemini and AI Overviews costs €4,370.
Best for: B2B companies that want a dedicated team writing about 20 pieces a month on their own site, on month-to-month terms.
3. Siege Media
Siege Media's GEO service runs one program across the surfaces assistants cite: bottom-funnel comparison and pricing content, research reports and digital PR, a disclosed Reddit presence and affiliate partnerships. Its DataFlywheel technology refreshes a client's pages quarterly or faster. The first two months set a baseline LLM share-of-voice benchmark and a 12-month roadmap that ties every asset to a prompt; then citations, share of voice and revenue are reported monthly. If you lack proprietary data, Siege Media helps you create it, for example with a survey. It fits SaaS, fintech, e-commerce, cybersecurity, education and travel brands that can commit to six months or more. Its GEO page shows no price; its content marketing page sets an $8,000 monthly minimum on a 12-month contract with a 30-day out clause, as of November 2026.
Best for: product brands that want content on their own site plus PR, Reddit and affiliate placements run as one program for six months or more.
4. Animalz
Animalz's answer engine optimization service starts with an audit of where Google AI Overviews, ChatGPT, Perplexity and Gemini mention or miss your brand, then a roadmap. The writing comes in two forms: micro content refreshes that re-align your existing content with answer engine outputs, pairing its proprietary AI workflow with editorial judgment, and new content created with you to cover critical prompts. Mention outreach to highly cited sources, YouTube video aimed at prompts, and reporting on AI visibility, brand mentions and revenue impact round it out. Animalz flags site structure, crawlability and speed issues; the fixes can be phased or handled by your own developers. No price is published.
Best for: companies with an existing content library that want it re-aligned to AI answers, plus new pages for the prompts they miss.
5. Frase
Frase calls itself an SEO and GEO content platform. On its pricing page, the Starter plan costs $39 a month billed yearly, as of November 2026: one site, 10 articles a month, SEO and GEO scores, and AI Visibility tracking on ChatGPT and Google AI. Perplexity is added on Professional ($103 a month billed yearly), and Claude and Gemini on Scale ($239 a month billed yearly). Frase drafts in your voice and publishes to WordPress, Webflow, Sanity or Wix, so the pages land on your own site; nothing ships until you approve it, unless you switch on auto-publishing. If you use its hosted FraseCMS instead, the $19-a-month Basic tier adds your own domain.
Best for: small teams that will review and publish the drafts themselves and want a low published entry price.
6. Writesonic
Writesonic presents itself as an AI search visibility platform. Its pricing page shows the Starter plan at $79 a month billed annually, as of November 2026: daily tracking of 50 prompts in ChatGPT, Gemini and Google AI Overviews, 15 AI articles a month and 10 site audits. Growth, at $399 a month billed annually, raises that to 200 prompts and 50 articles and adds sentiment analysis. Enterprise covers all 8 AI platforms Writesonic tracks, with fact-check and citation-decay features. Listed integrations include WordPress and Google Search Console, and you can start free without a credit card.
Best for: in-house marketers who want AI article drafts and daily prompt tracking in one tool.
7. Surfer
Surfer is a platform that pairs an optimized content editor with AI visibility tracking, to create content that ranks on Google and gets cited by AI search engines. On its pricing page, the Standard plan costs $99 a month billed yearly, as of November 2026: the Surfy AI writing assistant, 360 documents to create or optimize, one-click content optimization and 25 AI prompts tracked in ChatGPT, refreshed weekly. Pro, at $182 a month billed yearly, tracks 50 prompts daily across ChatGPT, Gemini, Perplexity, AI Overviews and AI Mode, and adds internal linking, content gap ideas and custom voices. Integrations include WordPress and Google Docs. The smaller Discovery plan, at $49 a month billed yearly, also includes Surfy and creates or optimizes 120 documents, but tracks no AI prompts.
Best for: SEO teams and writers who draft with AI help and want optimization guidelines and prompt tracking in one editor.

What are the red flags when you hire someone to write for AI search?
Three patterns should make you slow down.
A promise of a specific answer, position or ranking. Ask what is promised, on which questions, how it is measured and what happens if it is not met. A promise without written conditions is a sales line, not a commitment.
Volume without sources. A quote for dozens of articles a month says nothing about whether each one carries checkable facts. Google's guidance on generative AI content says that using AI tools to generate many pages without adding value for users may violate its spam policy on scaled content abuse, and that all AI-generated content should be fact-checked and reviewed by hand before publishing. Whether assistants cite AI-assisted pages at all is covered in Does ChatGPT Cite Articles Written With AI?
Articles on the provider's domain instead of yours. A page on someone else's domain builds their domain. Company blogs do get cited: in our measurement of 21 October 2026, the most cited sources in answers to GEO questions were the blogs of GEO agencies and tool vendors themselves. Ask where every page will live, and make sure the answer is your own domain.
What should you do first?
Start with a baseline. Run our free check: in about 30 seconds it generates five buyer questions from your homepage, puts them to ChatGPT and Perplexity, and shows one answer right away and all five once you create an account. Keep those questions. Whoever you hire, ask them to put the same questions to the assistants before the first page goes live and again after, and to show you which answers name you and which sites they cite.
Then choose between a service and a tool. If nobody on your team has hours each week to write, fact-check and publish, a done-for-you service fits; if you have a writer, one of the tools above can be enough. Should I Hire a GEO Agency or Use a GEO Tracking Tool? walks through that choice.
Frequently Asked Questions
Can an AI writing tool alone get my company cited by AI assistants?
Not on its own. Frase, Writesonic and Surfer write drafts and track answers, and Frase can publish by itself when you switch that on; your team still supplies the facts and checks each draft before it goes live, as Google asks for all AI-generated content. If nobody has that time, a done-for-you service is the better fit.
Should the articles go on my site or on the provider's?
On your own site. A page on a provider's domain, or on a hosted blog without your domain, builds that host rather than you. Ask every provider where each page will be published before you sign.
What does a service that writes content for AI search cost?
Among the providers above, published prices as of November 2026 start at $39 a month billed yearly for Frase's Starter plan; Discovered Labs' Establish retainer is €6,995 a month on a six-month commitment, and Siege Media's content marketing minimum is $8,000 a month. ItGrows's plan is $499 a month, month to month, plus a one-time $499 setup; the setup is free with $1,497 for 3 months upfront or $4,788 for a year ($399 a month, 20% off). Animalz publishes no price.
How do I know whether the content is working?
Put the same buyer questions to ChatGPT, Claude, Gemini and Perplexity before the first page goes live, then again at a fixed interval, and compare only the same questions. Count the answers that name you and note which of your pages they cite. How Do You Measure AI Visibility Over Time? covers the method.
