What each tool does
Perplexity is an AI tool for asking questions and getting answers, widely known as a search-style answer assistant. It suits students, researchers and curious users who want quick answers and help with research. Its current features and plans were not visible when reviewed, so check its site for details.
DeepSeek is an AI company offering a chat assistant on the web and in a mobile app, with deep thinking and smart search features. It releases several models as open source, including DeepSeek-V4 and DeepSeek-R1, and offers an API platform for developers.
Key differences
- Approach: Perplexity centres on answering questions and research; DeepSeek is a broader chat assistant plus a model provider.
- Openness: DeepSeek publishes open-source models; Perplexity does not list this.
- Developer options: DeepSeek highlights its API platform; Perplexity's listing focuses on end users.
- Search: both are useful for looking things up, with DeepSeek listing a smart search feature alongside its deep thinking mode.
Which should you choose?
Choose Perplexity if research is your main use, such as gathering background for assignments, checking facts or exploring a topic quickly.
Choose DeepSeek if you want to reason through harder problems with deep thinking mode, try open-source models or build on an API.
Both have free options to start. Paid plans or API billing are usually handled online, so users in Pakistan should confirm card options and check the pricing page for current plans.
Can you use both?
Yes. You could gather information on a topic with Perplexity and then use DeepSeek's deep thinking mode to work through a tricky problem based on what you found.
