Not another AI article generator
Without it
- A prompt goes in and a generic article comes out, with no idea what ranks today.
- Every post has the same shape, whatever the search calls for.
- You spend an hour fixing the tone, the facts and the giveaway phrasing.
With Evergreen AI
- Each article starts from the live Google results and the questions people ask about the topic.
- The format is picked from 14 types to match what already ranks.
- It writes as your business, with your products, prices and calls to action.
How it works
Four stages behind every article
- 1
Pick the format
It scores 14 article formats against the topic and what already ranks, then sets a word count to match.
- 2
Read the results
It reads the live Google top 10 and the People Also Ask questions, and studies the pages that rank.
- 3
Plan the article
An outline with section-by-section word targets, an FAQ, and links to up to 12 of your own pages.
- 4
Write and check
Claude writes it in your voice. Its length is checked against the target, an article well short of it gets another pass, and em dashes are stripped before it ships.
In depth
What makes the writing worth publishing
The right format
14 formats, chosen for each topic
A “how do I” search needs a step-by-step guide, not an essay. Evergreen AI scores every format against the topic and the pages already ranking, and picks the one that fits.
- How-to articles, beginner’s guides and pillar guides
- Myth-busting, problem-solution and how-to-choose guides
- Pricing guides, comparisons, alternatives, best-of lists and roundups, when you allow competitor mentions
Your voice
It sounds like your business, not a chatbot
Set how you write once and every article follows it. Evergreen AI fills these in from your site to start, and you can change them any time.
- Formality: casual, balanced or formal
- Reader level: beginner, mixed or expert
- Up to three tone words, like friendly, direct or expert
- A blocklist of terms for it to avoid
Built for AI answers
Structured to get quoted
AI assistants quote pages that answer the question directly. Every article leads with the answer, works through the questions people search for, and closes with an FAQ.
- The answer up front, before the detail
- A closing FAQ section, planned with the article
- A meta description and a clean slug before it publishes

FAQ
Questions, answered
Which AI writes the articles?
Claude, from Anthropic. Faster models handle the smaller jobs along the way, like choosing internal links and finding a header image.
How long are the articles?
It depends on the format. Each of the 14 formats has its own range, from 800 words for a definition piece up to 6,000 for a pillar guide, and the pipeline sets a target for each article.
Can I edit an article before it goes live?
Yes. Edit it directly, or describe the change you want in plain English and it rewrites the article for you. You get three AI revisions per article.
Will it mention my competitors?
Only if you allow it. Pricing guides, comparisons, alternatives, best-of lists and roundups stay switched off until you turn on competitor mentions in your settings.
How many articles do I get?
Up to 30 a month on a paid plan, at whatever cadence you choose.
