Questions & Answers

As answered by people managing StackSource and HarperFlow.

What makes your product unique?

HarperFlow's answer:

HarperFlow isn't another AI writer — it's a fully-automated publishing pipeline built for GEO (Generative Engine Optimization). It profiles your site, finds the questions buyers actually ask AI, researches each article across 8–12 real sources, fact-checks every claim, and publishes finished, on-brand posts straight to your CMS. The output is engineered to get your business cited by ChatGPT, Perplexity, and Google's AI Overviews — not just ranked. Uniquely, it's 100% automated yet 100% steerable, and fact-grounded so AI represents your brand accurately.

Which are the primary technologies used for building your product?

HarperFlow's answer:

  • Cloudflare Workers (Hono/TypeScript) API
  • Supabase Postgres with row-level security
  • an n8n multi-agent pipeline orchestrating Eden AI (DeepSeek-V4-Pro), Mistral, and a GPT-4o quality judge
  • SerpApi (Google AI Overview), Brave, and Jina Reader for research/citations
  • Stripe billing; a React + TipTap dashboard on Vercel; publishing natively to Webflow, Shopify, and Wix.

What's the story behind your product?

HarperFlow's answer:

HarperFlow started from a simple shift: buyers now ask ChatGPT, Perplexity, and Gemini who to buy from — and most companies are invisible in those answers. We watched "GEO" fill up with snake oil and content mills that published endlessly without ever getting cited. So we built the opposite: a fact-grounded, multi-agent pipeline that researches like an analyst and publishes like a team, engineered purely to earn AI citations. And we proved it the only honest way — by running it on our own blog first, in public.

Why should a person choose your product over its competitors?

HarperFlow's answer:

Most "AI content" tools optimize for old-school SEO and pump out generic articles that never get cited — money down the drain. HarperFlow is built for how people search now: it targets what AI engines actually quote, grounds every claim in a real source (so it won't misrepresent you), and publishes natively into Webflow, Shopify, WordPress, and Wix with no copy-paste. You get a whole research-to-publish pipeline, not a prompt box — for less than the cost of a single freelance article. It's the honest, quality-first option in a category full of hype.

How would you describe the primary audience of your product?

HarperFlow's answer:

Founder-marketers and lean content/growth teams at B2B SaaS and DTC companies who want a hands-off blog that actually drives AI-search discovery. Webflow and content agencies are a second core audience — they run HarperFlow across all their client sites, with multi-site and reseller pricing.
