How We Analyze AI Tools — 6-Step Research Process

By Navneet Arya ·

Key takeaways

  • Free-tier claims are tested directly, not taken from marketing pages, since many tools hide rate limits or watermarks.
  • 200+ verified reviews per tool are read across Trustpilot, G2, Capterra, and Reddit before a verdict is written.
  • Every tool is benchmarked against 2–4 direct competitors on the same criteria, not scored in isolation.

Every AI tool reviewed on AI Nexus goes through a consistent 6-step research process. Here's exactly what that looks like.

  1. Official Documentation Review — We read every word of the tool's official docs, changelog, and API reference before writing a single sentence. This means reading the actual feature documentation, not the homepage or pricing page — checking what features exist at each tier, what the API limits are, and what changed in recent versions.
  2. Free Plan Verification — Every tool's free tier is tested against what it advertises. Limitations, watermarks, export restrictions, and rate limits are all documented, since many tools advertise "free forever" but hide critical limitations.
  3. Review Aggregation (200+ Reviews) — We read verified user reviews from Trustpilot, G2, Capterra, and Reddit — 200+ per tool — to find recurring complaints and praise patterns rather than relying on a star average.
  4. Reddit Sentiment Analysis — Real conversations on Reddit (r/artificial, r/ChatGPT, r/MachineLearning, and tool-specific subreddits) reveal pain points, workarounds, and deal-breakers that polished review sites miss.
  5. Live Pricing Verification — All pricing is verified against the live pricing page on the day of publication, screenshotted with a date. INR pricing is verified separately for Indian audience articles.
  6. Competitor Benchmarking — Every tool is compared against 2–4 direct competitors using the same criteria: features, pricing, limitations, and target use case.

Frequently asked questions

Why read Reddit instead of only structured reviews?

Structured review platforms surface a star rating; Reddit threads surface long-term frustrations, workarounds, and deal-breakers that don't show up in a 5-star summary.

Why verify free plan claims separately?

Many tools advertise "free forever" while hiding rate limits, watermarks, or export restrictions. Testing the free tier directly catches gaps that marketing pages don't mention.

How often is pricing re-checked?

Pricing is verified against the live pricing page at time of publication, and reviews are updated when a tool changes its pricing or features.
