Show HN: ReviewStack – API that aggregates reviews from YouTube and Reddit

1 points by browndev 4 hours ago

I built an API that takes a product name, scrapes reviews from YouTube and Reddit, and returns structured sentiment analysis in a single JSON response. Live demo (no signup): https://reviewstack.vercel.app/demo

The response includes a normalized score (1-10), a plain-text summary, pros/cons lists, recurring themes with sentiment, and source attribution linking back to the original content.

The AI layer uses Claude by Anthropic. It reads the collected reviews and extracts structured data. The value is in not having to maintain scraping infrastructure, handle rate limits across platforms, or write your own extraction prompts.

Stack: Next.js API routes, Vercel for hosting, Stripe for billing, YouTube Data API + Reddit JSON endpoints for sourcing, Claude for analysis.

Pricing: free tier at 50 lookups/month, paid plans at $29/mo (500 lookups) and $79/mo (2,000 lookups). Solo/bootstrapped project.

Happy to answer questions about the scraping approach, accuracy, or anything else.
