Variant synthesis
Every topic yields three complete drafts with different angles — a how-to, a data-led piece, a contrarian take — so you compare real alternatives, not rewrites.
Content experimentation platform
Stop publishing first drafts. Publish winners.
AutoBlogLab turns every blog topic into an experiment: the AI writes three distinct article variants, scores each with a 14-signal SEO assay, and hands you the strongest one — ready to publish.

Lab protocols
Everything a serious blog needs to test, not guess
Six core protocols run in every workspace — from variant synthesis to publishing the winner.
The SEO Assay
A 14-signal score across intent match, structure, readability and originality. Each variant gets a 0–100 result with a full breakdown of why.
Headline experiments
Ten headline candidates per article, ranked for clarity and click intent, with A/B pairs you can carry into your email and social tools.
Tone calibration
Dial the voice from strictly professional to conversational, and the Lab holds it consistent across every section of every variant.
Publish the winner
One click sends the winning draft to WordPress or Ghost with headings, meta description and alt-text suggestions intact.
Brand guardrails
Banned phrases, required disclosures and style rules are enforced at generation time, so nothing off-brand ever reaches a draft.
The method
Four stages, one winning article
The Lab follows the same loop good research does — and it runs in under two minutes.
Hypothesis
Enter a topic, audience and goal. The Lab drafts a brief and three distinct angles worth testing.
Synthesis
Three full article variants are written in parallel, each following its own angle and your tone settings.
Assay
Every variant is scored on 14 ranking signals. You see the numbers, the breakdown and the verdict.
Publish
Edit the winner if you like, then push it to your CMS or export it — with the losing variants archived for reuse.
The elements
Every content type on the periodic table
Experiments aren't just for long-form. Test any format your channels need.

Field notes
From teams that test before they publish
Note 01 · Niche publisher
"Seeing three angles side by side changed how we plan. Half the time the winner is the angle we would never have picked ourselves."
DK
Daniel KovacsEditor, outdoor gear blog network
Note 02 · Agency
"The Assay score ended our internal debates. Clients get a report that shows why a draft was chosen, and revision rounds dropped noticeably."
MR
Marta RuizContent lead, digital agency
Note 03 · SaaS marketing
"We moved from two posts a week to five without hiring, and our average time-on-page went up — because we only publish the variant that earned it."
JW
James WhitfieldHead of growth, B2B SaaS
Note 04 · Solo blogger
"On the Starter plan I basically got an editor. The score breakdown taught me more about structure than a year of reading SEO blogs."

Questions
Frequently asked questions
One topic, three drafts. For every topic you enter, the Lab writes three complete article variants with genuinely different angles, then scores each one so you can publish the strongest version instead of the first version.
On this demo site the generator runs entirely in your browser with a template engine, so no key is needed. In production, AutoBlogLab connects to leading AI models through a secure server-side integration — your key never touches the browser.
Yes. Professional and Agency plans push winning drafts straight to WordPress and Ghost, and every plan supports Markdown and .txt export.
Fourteen signals across four groups: search intent match, structure and headings, readability, and originality. Each variant gets a 0–100 score with a breakdown so you know why it won.
Anytime, from your dashboard, in two clicks. Your plan stays active until the end of the billing period and your documents remain exportable.
