“I have tried the 3 of them and Linkup seems to have a slightly different approach, with connections to premium sources while Exa seems to be a bit faster. Curious what is your preferred option out of the 3 (or if you have other solutions). exa.ai linkup.so tavily.com”
“A big portion felt like an ad for Exa, information about their business. The title "Future of RAG" over promises and under delivers.”
“"This was a really thought-provoking video. I agree that traditional search engines like Google rely heavily on keyword matching, which often misses contextually relevant information. The idea behind Exa seems promising—if it can leverage AI to understand intent and context rathe”
“Take a look at Extruct AI - similar to Exa, but more optimized towards the company search”
