# The 4 best general-purpose AI agents (2026) — The Agents Index

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

Agents that plan and carry out open-ended tasks on their own, with a browser, a computer or your apps.

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.
