Research posts
Multi-step researchers that produce sourced reports and briefs.
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.
- Single-product reviews of the leading research tools
- Comparisons across the agentic-search category
- How-to guides for AI-accelerated research workflows
- Capability deep-dives (agentic RAG, deep research, citation quality)
