Platform for exploring and publishing research papers.

Academic research

I've tried to find the exact articles via WoS, Google, or Scopus. Despite using a very advised and complicated search query, it was just a waste of time. Perplexity didn't help either. The Jenni AI, which may add useful links when generating text, finds nothing but trash. SciScape gave exactly what I needed from the first query! A couple of fresh relative articles with very exact topics!

It made my life so easy! It used to take me days sometimes to find the right information, tediously reading through papers to find the relevant data. Epsilon automated the entire process for me. Now, I find the relevant information in just a couple searches

Can't wait for mobile app!. I just realized it works in mobile web pretty well! As it doesn't seem like it loads heavy mp3 for voice, it's quite nimble compare to the other products. Love it!
