PaperBrain

PaperBrain is an AI research platform that makes scientific literature easier to explore and understand. It helps students and researchers find relevant papers with smart searches, then quickly grasp what each one is about.

You can upload your own papers, chat with them to ask questions and clarify difficult sections, and even turn papers into audio podcasts to listen to while commuting. PaperBrain also helps create content from the latest research, and according to the company it is trusted by more than 100,000 researchers across many fields.

Good fit if you: read a lot of research papers and want faster ways to discover, understand and summarise them.
Less ideal if you: need full reference management with citation styles; pair it with a tool such as Zotero.

Pricing: free to start, with optional paid plans for more features.
