“Open evidence is amazing. I use it every day for work as a primary care physician. It's also free!”
“OpenEvidence is not the end all be all. It's just free, got deals with major journals, and is capturing market share fast. https://arxiv.org/abs/2512.01191 It won't be free forever. It'll be $200 a month before you know it (once they nail more features down)”
