## Recent user reviews

- 4/5 (2026-11-05): We use Claude for long documents we would rather not skim: comparing tool docs, pulling a structure out of a research dump, and checking whether a draft actually answers the question. The long context is why we keep it open next to ChatGPT. The limit is pace and occasional over-caution: it can hedge or stop short when we only wanted a tighter paragraph.
- 5/5 (2026-08-05): The best LLM for frontend React code generation hands down. Artifacts save hours of test setup.
