A reading tool, made for people who still read.

Synthara is a workspace for the documents you read closely. You drop in PDFs, preprints, slide decks, or saved articles. Synthara indexes them locally to your account and lets you ask questions across the whole library, with passage-level citations that point straight back to the source.

We do not believe every search needs to be conversational, and we do not believe every conversation needs to be a chat. The interface tries to disappear when you are reading and reappear when you have a question.

We will not train on your documents. We will not surface them to other users. We will not build a feed, a social layer, or notifications you did not ask for. The goal is one good reading tool, not a platform.
