# The 4 best AI data analysis agents (2026) — The Agents Index

> Source: https://theagentsindex.com/category/data-analysis-agents (curated, re-verified)

Agents that work on your own data. They write and run SQL and Python, build the chart or report, and answer questions about your data in plain language.

4 agents in this category, ranked by what we can confirm about each (a public price, an API and docs, independent sources, stated limits; payment never changes the order). Each name links to its answer-first markdown twin.
