AI Tools Directory

Honest pros and cons, who each tool is not for, and pricing dated to when we last checked it.

ChatGPT

8.9

General-purpose AI assistant for writing, analysis and everyday tasks.

Verdict: The safest default assistant: broadest feature set and ecosystem, excellent for general work. Specialists beat it in narrow lanes — research with citations, very long documents — but as a first AI tool it is hard to argue against.

Claude

8.8

AI assistant known for long documents, careful writing and coding.

Verdict: The strongest choice for long documents, careful writing and agentic coding. Writing quality and instruction-following are class-leading; the ecosystem of third-party plugins is smaller than ChatGPT's.

Gemini

8.4

Google's AI assistant, woven through Search, Gmail and Workspace.

Verdict: Unbeatable if your work already lives in Gmail, Docs and Drive — the integration is the product, and the free tier is the most generous of the major assistants. As a standalone chat experience it trails its rivals in polish.
