While the interface may take some getting used to, Research Rabbit can be an invaluable tool for ensuring comprehensive literature coverage.

DeepSeek: A Free General-Purpose AI Model

DeepSeek offers a free, general-purpose AI model that can be used for various academic tasks. While it may not be as specialized as some paid academic AI tools, it provides a no-cost option for researchers on a budget.

Potential Uses of DeepSeek in Academia

• Brainstorming research ideas
• Summarizing complex concepts
• Drafting initial literature reviews
• Generating research questions

Considerations When Using DeepSeek

• As a general-purpose model, it may not have the depth of knowledge in specific academic fields that specialized tools offer.
• There have been some privacy concerns raised, as the tool is based in China. Researchers should be cautious about inputting sensitive or confidential information.
• The model can be run locally for those with privacy concerns and the technical know-how.
