AI Search & Research Tools

Search engines have been the same for decades: type a query, get links, do the reading yourself. AI search tools change that equation — but they come with tradeoffs worth understanding.

Perplexity AI: The Leader

Perplexity reads the web for you and writes a synthesized answer with citations you can actually check. Ask "What are the latest findings on ozempic and heart health?" and you get a paragraph-form answer with numbered sources alongside it.

Pricing: Free tier is genuinely useful. Pro plan $20/month adds more powerful models (including Claude and GPT-4), higher daily limits, and file upload for analysis. Best for: Medical questions, financial research, current events, fact-checking.

Google AI Overviews

Google now places an AI-generated summary above traditional results for many queries. Convenient for quick answers but has drawn criticism for occasional errors. Uses Google's Gemini model.

ChatGPT Search

OpenAI added real-time web search to ChatGPT. Most useful when you want conversational follow-up — ask "tell me more about that third point" and continue refining in dialogue. Available on the free tier.

Elicit: Research-Grade AI

Built specifically for academic and scientific research. Submit a research question; it searches peer-reviewed papers, extracts key findings, compares methodologies, and summarizes across multiple studies. Not flashy, but remarkably powerful for understanding what the science actually says. Free tier; paid from ~$10/month.

You.com

Combines AI answers with traditional search results. A reasonable free alternative to Perplexity with a cleaner interface than Google's cluttered results page.

When to Use AI Search vs. Traditional Google

Use AI search when: You need a synthesized answer from multiple sources, researching an unfamiliar topic, or fact-checking a claim.

Stick with Google when: Looking for a specific website, shopping, searching for local businesses, or need breaking news.

The Hallucination Problem

  • Always check cited sources. Perplexity's citations are clickable — use them.
  • Be skeptical of specific numbers, dates, and names. These are where errors cluster.
  • Cross-reference with a second source for anything consequential — medical, legal, financial decisions.
