Quick take, not a full review
Which one should you pick?
Pick DeepSeek if this matters most to you: Free web chat with strong coding and math performance. Pick Perplexity if this does: Every answer links the sources it drew from.
Both are freemium, so price is unlikely to decide it.
We have not fully rated both tools yet, so treat this as a starting point rather than a verdict.
The trade-offs are real on both sides: DeepSeek's biggest limit is that data is processed in China, a privacy and compliance concern for many; Perplexity's is that summarizes sources rather than reasoning deeply on its own.
For pricing detail and limits, read the full DeepSeek review or the full Perplexity review.
