Frequently asked questions

Are AI study assistants safe to use for university coursework?

Yes, provided they are used ethically for brainstorming, summarising, and editing rather than generating entire submissions, which may breach academic integrity policies.

Can AI study assistants help with scientific research?

Tools like Consensus and Elicit are specifically designed to search peer-reviewed literature, extract methodologies, and summarise scientific findings accurately.

Do I need a paid subscription to use these tools effectively?

Most platforms offer robust free tiers, though heavy users or those requiring advanced features like unlimited research queries or long-form document analysis will benefit from paid plans.
