AI SEO Content Generator

Point it at a page you already own. It learns how you write, reads what you actually offer, researches the keywords and sub-queries, checks the top five, and hands back a full draft with schema, meta tags and an internal link plan.

How This Tool Works

Most content tools hand you one piece. A keyword list. A brief. A score on text you already wrote. You are still the one who stitches them together, and the stitching is where the hours go.

This runs the whole chain in one pass. Thirteen steps, each one visible while it works, so you can read the keyword data at twenty seconds instead of waiting three minutes for everything at once.

  1. Writing-style profile. The reference page gets read for sentence rhythm, person, contraction use, paragraph length and vocabulary. That profile is what the draft is written against.
  2. Offering and entities. What you sell, where you work, which names and terms belong to you. The draft draws its facts from here instead of inventing them.
  3. Cannibalisation check. The live top ten for the target term gets scanned for your own domain. If a page of yours is already in there, the tool says at which position and recommends expanding that page instead of publishing a second one.
  4. Keyword research. Live volume, difficulty and cost-per-click from DataForSEO, for the market you picked.
  5. Query fan-out. The eight to twelve sub-queries an AI engine generates to answer your topic, each scored for how likely it is to pull an external citation.
  6. People Also Ask. Real questions from the live result page, which arrive with the same request as the next step.
  7. Competitor topics. The five ranking pages get fetched and reduced to the topics they cover.
  8. Gap analysis. What none of the five covers. That list is the reason a new page can outrank them.
  9. Outline. H2s built from the high-citability sub-queries, in the wording the engines used.
  10. Draft. Written in the style from step one, with the facts from step two.
  11. Craft check. The draft gets measured against Lumina's own writing rules: filler words, rhetorical triplets, two sections opening with the same shape, a section with no concrete figure in it. Up to three failing sections are rewritten, then measured again.
  12. Schema and meta. JSON-LD for the page type, plus title and description measured in pixels rather than characters.
  13. Internal links. Your sitemap gets read, and the tool names which existing pages should link to the new one, with anchor text.

What Google Says About AI-Generated Content

Google's position has been the same since February 2023 and it is narrower than most summaries of it. Appropriate use of AI is not against guidelines. Using automation to manipulate rankings is.

The word doing the work in that guidance is scaled. What the spam policy targets is content produced at volume with little value, regardless of whether a person or a model produced it. A single well-researched page written with AI assistance sits nowhere near that line. Four hundred near-identical city pages do, and they did before AI existed.

So the honest framing for any tool in this category: it does not make your content rank. It removes the research and drafting hours. The judgment, the expertise and the fact-checking stay yours, and they are still what decides whether the page deserves to rank.

How to Use an AI Draft Without Hurting Rankings

The failure mode is not that the text reads badly. Modern models write fluently. The failure mode is that they write things which are plausible and false, and fluent prose hides that better than clumsy prose does.

That is why every factual claim in the output carries its source. A claim traced to your own page is marked as yours. A claim traced to a competitor page shows which one. A claim with neither shows up as an open gap, in the draft, where you cannot miss it.

Three habits matter more than any tool setting:

How This Compares to Surfer, Clearscope and Frase

Those three are mature paid products and their feature lists move every quarter, so treat any comparison table as a snapshot with a date on it. Surfer, for one, automates internal linking on its higher plans, which a table written a year ago would have told you it doesn't. Checked in September 2026, entry plans start around $49 at Surfer, $45 at Frase and $129 at Clearscope, and the team tiers run into the hundreds. Read their pages, not mine.

What doesn't move is the assumption each tool makes about what you bring. They start from a keyword and an empty editor: the voice and the facts are yours to supply. This one starts from a page you already own and reads both off it, which is why the reference page field isn't optional and why pointing it at somebody else's site produces their voice, not yours.

What the draft carriesWhere it comes from
Writing styleA profile read off the reference page you own
Facts and offeringThe same page, so the draft repeats your claims instead of inventing new ones
Source trailOne source per claim, and anything unsourced marked as an open gap
Cannibalisation warningYour own domain's position in the live top ten for the term
HeadingsThe sub-queries an AI engine generates for the topic, scored for citability
Internal link planThe first 120 URLs in your sitemap.xml
Craft checkLumina's own writing rules, applied to the finished draft
PriceFree, one draft per IP per day

The craft check is the row worth pausing on, and it deserves an honest label. Every generator in this category scores its own output, and this one is no exception: the rules it checks against are Lumina's, not an outside judge's. What it does differently is say the failures out loud, rewrite up to three of the weakest sections, and then report what it still couldn't fix. For a second opinion that doesn't come from the same codebase, run the finished draft through the AI Humanizer and the Heading Checker yourself.

When Not to Use It

A tool that only ever says yes is a sales page, not a tool. Cases where this one is the wrong choice:

FAQ

Is the draft ready to publish as it is?+
No, and any tool that says otherwise is selling you something. The draft is complete in structure, style, schema and meta tags, but every factual claim carries its source and anything without one is marked as an open gap. Close those gaps, check the numbers, add what only you know, then publish.
What does it cost?+
Free, one full draft per IP per day, no signup and no card. The limit is low because a single run costs real money in API calls, roughly 20 cents. Add your own OpenAI and DataForSEO keys in Settings and the limit disappears, because then you pay the providers directly.
How long does a run take?+
Between 90 seconds and three minutes, depending on how fast the competitor pages respond. Each of the thirteen steps shows its result the moment it finishes, so the keyword data is readable after about 20 seconds and the outline after about 70. The draft itself comes last.
Does the reference page have to be my own site?+
It should be. The style profile and the offering both come from it, so pointing at someone else's site means writing in their voice about their services. Use any page of your own that reads the way you want the new one to read.
Will Google know the text was written with AI?+
Possibly, and it matters less than the question implies. Google's guidance permits AI assistance and targets scaled low-value content instead. What does matter is the draft not reading like template output, which is why the style profile exists and why running the result through the AI Humanizer is worth the extra minute.
Can I get the result as a PDF?+
Yes. The PDF button opens a print view containing the brief, the outline, the full draft, the schema blocks, the internal link plan and the source trail. Text stays selectable and searchable because it is real text, not a screenshot, so you can copy out of the PDF later.
