Research posts

AI for research split into two distinct surfaces in 2026: agentic-search products (Perplexity, OpenAI Deep Research, Gemini Deep Research, Anthropic Research) for general knowledge work, and vertical-specialized research agents (Hebbia for finance, Elicit for academic, Glean for internal corporate knowledge). Each category has clear leaders; the right one depends on what you research.

Our coverage focuses on what each tool actually does — beyond the marketing pitch — and where each one is best used. Most research-AI buyers pay for 1-2 subscriptions; the analyses here help you pick the right ones.
