AI AI Agents Tools
85 tools ranked by usefulness.
The practical difference between an assistant and an agent is simple: an assistant suggests, an agent does. An AI agent browses sites, fills forms, writes and runs code, sends messages — and makes its own intermediate decisions to reach the goal you set.
That makes this the most exciting category and the one that needs the most care. Three questions narrow the choice fast: does the agent work inside one app or across your whole browser? Can you review each step before it runs, or does it work unsupervised? And does it keep your data local or send it to the vendor's servers? Most agents listed here answer all three clearly on their own pages, and we've noted it in each "why we picked it."
Ranked by usefulness, updated daily. If you're a developer, see coding tools as well — that's where the coding agents specifically live.
