SYNTHESE

A note to our readers. Synthese AI is pausing operations as we step back to reassess our direction. Rather than continue down a path we're not fully confident in, we want to rethink what this platform should be — not just another news feed, but something meaningfully useful. Thank you for reading and engaging with us. If and when we return, it will be with a clearer vision.

Editor’s Note

Simple and effective. Upload a paper or report, ask questions, get answers with page references. The simplicity is the product — no learning curve. Accuracy is good for well-structured documents but struggles with scanned PDFs and complex tables.
