Sources, not vibes
Perplexity
A search assistant that answers with links you can click. Better than a bare chatbot when you need a starting bibliography, and still capable of citing a page that does not say what the summary claims. Open the sources. For papers specifically, Elicit, Consensus, and Scite go deeper.
Best for
Early research and fact-finding when you want links, not a polished paragraph to paste into the book.
Pricing
Freemium. Free cited answers with limits. Pro adds stronger models and higher research caps.

Drafting
ChatGPT
The general assistant most writers already have open. Useful for brainstorming, blurb variants, and line rewrites if you paste the scene and say what you want. It does not hold a novel together unless you build that memory yourself with projects or files, and it will invent sources if you let it.
Best for Writers who want one flexible assistant and will bring their own outline, pages, and skepticism.
FreemiumFiction and nonfictionDrafting
Claude
A general assistant that writers often prefer for long passages, tone, and a calmer revision pass. Projects can hold notes and chapters you upload. It is still a chat, not a novel app: continuity across a whole book is only as good as the pages you put in front of it.
Best for Drafting and revision when you want a careful reader more than a plot machine.
FreemiumFiction and nonfictionResearch
Consensus
Searches scientific papers for what the evidence says about a question, and tries to show agreement rather than a single link. Good for 'does this claim hold up?' and a poor place to learn narrative craft. Read it as a map of a literature, then go to the studies that matter.
Best for Nonfiction writers checking whether a popular claim survives contact with research papers.
