Paaing: Recursive People Also Asked Research SaaS — 64+ Questions Per Keyword, AI Articles Instant

People Also Asked boxes are one of the richest signals for understanding how real users think about a topic — but standard SEO tools only scratch the surface. Most tools make simple HTTP requests to Google search result pages, miss the dynamically loaded PAA boxes entirely, and never expand the tree recursively. At depth 2 or 3, the question graph grows exponentially — and that deeper data is where the real content strategy gold lives. Content teams were manually clicking 'expand' on Google PAA boxes, copying questions into spreadsheets, and spending hours writing answers and articles. There was no tool that combined recursive PAA extraction with AI content generation in a single workflow.

We built Paaing around Google's undocumented internal async/callback:10041 endpoint — bypassing the standard SERP HTML page entirely and hitting the same JSON endpoint Google's own UI calls to lazily load PAA boxes. Country-specific query context tokens (qc params) and a large static parameter block that mimics a Chrome browser session are pre-computed and injected per request. The scraper runs entirely async with aiohttp — all Level N parent keywords are processed simultaneously — making depth-3 searches fast even for complex, broad topics. A rotating proxy pool handles antiban, with per-request random proxy selection and automatic retry on connection failure. The graph builder converts the flat question list into a visually organised interactive tree with clear parent-child node structure for rich research visualisation. Three AI generation modes — snippet, short article, long article — are powered by the user's own API keys (OpenAI or Anthropic), keeping operating costs at zero for us while giving users full model flexibility. A full credit system with PAYG crypto billing, lifetime deal codes, and guest access makes the platform accessible at every price point.
