AI tools for writers
Draft, edit and polish long-form work.
ChatGPT
8.9General-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
8.8AI 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.
Image generation built into ChatGPT, strongest at following long prompts.
Self-organising notes that surface relevant material automatically.
Paraphrasing, grammar and citation tools built for students.
NotebookLM
8.5Turn your own documents into a grounded research assistant.
Verdict: The most trustworthy research assistant for working with your own material — source-grounding with passage-level citations is exactly how AI research should work. It only knows what you give it, which is both its limit and its point.
Gemini
8.4Google'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.
