🔎 Search & Research AI Tools
NotebookLM, Perplexity, Deep Research, long-doc reading, multi-source synthesis.
AI search and research tools have evolved from "alternative search engines" to "agents that run the research workflow for you." This hub focuses on real research workflows: NotebookLM for multi-doc comparison, Perplexity for fact checks, Deep Research modes in ChatGPT / Claude / Gemini for industry briefs. Every article gives a reusable "question → AI → conclusion" path, not yet another tool review.
