What is Deep Research in AI?

A product category launched by OpenAI in early 2025: an AI agent that plans an investigation, searches 30-100 sources, and returns a cited multi-page report. Took 5-30 minutes per query. Now offered by OpenAI, Perplexity, Google, and Anthropic.

How accurate is AI Deep Research?

For broad market / competitive / regulatory questions, 85-90% accurate in 2026 benchmarks. For numeric financial data, specialized tools (AlphaSense, Bloomberg) are more reliable because the underlying sources are higher quality.

Can AI replace a junior research analyst?

For the first draft of a research brief, yes — Deep Research tools produce work that's comparable to a junior analyst's 8-hour first pass. For the final report and the judgment calls, human analysts are still essential.

What is the cheapest AI for research?

Perplexity free tier, ChatGPT Free with search, You.com free, Gemini free, and Jarvis free tier all cover daily research. For Deep Research specifically, the paid tiers ($15-20/month) are necessary.

Is AI research safe for sensitive topics?

For free-tier tools, queries may be logged and used for service improvement. For sensitive topics, use enterprise tiers with no-training guarantees (Perplexity Enterprise, ChatGPT Enterprise, Claude Team, Jarvis with EU data residency for data at rest).
