Our Verdict
Pick Claude for one reason above all: Handles very long documents with a large context window. Pick DeepSeek instead if this matters more: Free web chat with strong coding and math performance. Both are freemium, so price is unlikely to decide it. The trade-offs are real on both sides, so weigh Claude's limits against DeepSeek's before committing.
