Our verdict
Anthropic positions itself as the safety-first alternative to OpenAI, and Claude genuinely reflects those values. It is significantly less likely to hallucinate on factual questions, better at following nuanced instructions, and produces more polished long-form writing than most competitors.
Claude's standout feature is its 200,000-token context window — the equivalent of roughly a 500-page book. This makes it invaluable for tasks like analysing long legal contracts, reviewing entire codebases, or maintaining continuity in extended research projects.
The free tier is functional. Claude Pro at $20/month gives priority access to Claude Opus, the top-tier model, along with Projects (a way to organise conversations with persistent context) and Artifacts (interactive documents and code previews).
For API users, Claude is favoured in enterprise contexts where output predictability matters: legal firms, medical research, financial analysis. The tradeoff is a slightly smaller third-party ecosystem than OpenAI.
Bottom line: Claude is the best AI writing assistant in 2026, and the first choice for anyone working with very long documents.
