Perplexity ai
Perplexity AI has web, academic and social media sources that you can choose for a search. The web focus searches web sites and the academic focus searches scholarly sources, although it is not clear what method Perplexity uses to identify these. One may also specify a site to search such as PubMed. The Deep Research feature (free for limited usage) generates an indepth report, while the auto presents a shorter answer.
Pros
- Provides a readable answer to a question with linked sources
- Can limit to a site such as PubMed
- Searches the web, and so can provide an up-to-date answer, which some older LLM models did not do
- Perplexity Deep Research allows in-depth searching and summarizing, producing answers with a scholarly tone.
- Some free Pro searches are allowed every few hours.
- The Pro version allows use of most recent LLMs in searching.
Cons
- Uses relatively few sources in its answers
- Has some hallucinations (may say information is in a source but it is not found in the source, or some sources may be made up)
- May sources without vetting quality if academic focus is not used
