Overview
Claude — Claude is the tool we reach for when the output needs to sound human. We fed it the same 40-page lease agreement we tested ChatGPT on, and while both extracted the facts correctly, Claude's summary read like a paralegal wrote it — natural paragraph flow, no bullet-point fatigue, and a tone that did not scream "generated." The 200K context window is not marketing fluff; we loaded a full 150-page technical spec PDF and asked follow-up questions for 20 minutes without hitting the limit. Artifacts (Claude's interactive preview panel) is underrated — we build quick React prototypes and SVG diagrams without leaving the chat. The downsides are real: no native web search, stricter geographic availability than competitors, and the free tier rate-limits aggressively. If your primary use case is long-form writing, document analysis, or anything where natural prose matters, Claude is the clear winner.
Jasper — Jasper is purpose-built for marketing teams, with brand voice and SEO mode.
