The honest answers.
No invented stats. No fine print.
What is GEO, and how is it different from SEO?
GEO is Generative Engine Optimization (AEO, Answer Engine Optimization, is its sibling). AI engines like Google AI Overviews, ChatGPT, and Perplexity do not rank pages — they quote content they can verify and attribute. HarperFlow ships every article with named citations, snippet-sized TL;DRs, FAQ coverage, and clean semantic structure so it can be quoted.
Is this just generic AI content?
No. Every article is scored by an independent AI judge across six dimensions — factual grounding, citation quality, brand-voice fidelity, GEO optimization, writing quality, and formatting — before you ever see it. Anything that misses the bar is rewritten automatically, and you hold the veto on everything.
How do you actually check quality?
An independent AI judge scores every draft across the six dimensions above. Our internal benchmark is an average of 84.9 out of 100 across a 15-article audited cohort — a benchmark, not a promise about your traffic. We only ever show numbers we can measure honestly.
Will the content sound like my brand?
Yes. During onboarding, HarperFlow learns your brand voice from your own site, then writes in it. You can review what it learned and correct anything before a single article is written. Brand-voice fidelity is also one of the six audit dimensions, so drift gets caught.
Do I lose control of what gets published?
Never. Nothing goes live silently. Every scheduled article arrives in a veto digest first — skip it, approve it with a visible publish time, publish it now, or reschedule it. If you do nothing, scheduled articles publish at their slot anyway, because you already saw them coming.
Which platforms do you publish to?
Webflow, WordPress, Shopify and Wix — all live, all built on their official APIs. HarperFlow maps to a collection you already have, creates a ready-made 33-field collection in one click, or adds only the missing fields to an existing one. It will not change your site’s design — articles inherit your fonts and accent color.
What does the free trial include?
7 days and 3 full articles, scheduling included. It is $0 today, though a card is required — cancel anytime before the trial ends and you will not be charged. One free trial per site.
What if an article fails the quality audit?
A make-up run is dispatched automatically, at no extra cost. Only delivered, publish-ready articles count against your monthly quota. Unused articles do not roll over — quotas reset each billing cycle.
How do payments and cancellation work?
Payments are handled by Stripe — your card details never touch HarperFlow. Cancel anytime from the Stripe billing portal; cancel before your trial ends and you will not be charged.
