Research papers

Ask your papers a question. See which paper said it.

A literature folder grows faster than anyone can re-read it. Étoiles lets you ask across all of your papers and shows the passage, in the paper, that backs each part of the answer.

Where this helps

You remember reading it, but not which paper, and not which section. Étoiles searches the text of every paper in your library, so you can ask the question you actually have and get pointed to the passage.

How it works

1. Add your papers as PDFs. In Étoiles Cloud, upload a folder of PDFs, or text and Markdown notes. On iPhone, import them from Files.
2. Ask across all of them. One question searches the whole library.
3. Check the passage. Each citation opens the passage it came from, so you can read it in context before you quote it or build on it.

Example questions

What it is not

• It is not a replacement for reading the paper. Use it to find where to read.
• It is not a reference manager and does not format citations for you.
• It searches the documents you add. It does not search journals or connect to paper databases.
• It works with the text in your documents. Check the cited passage when a paper's point lives in a table or figure.

Étoiles answers are written by AI and can be wrong. Open the cited passage to check before you rely on an answer.

Private by default

Unpublished drafts, reviewer comments and participant data deserve care. In the free iPhone and iPad app everything is processed on the device. In Étoiles Cloud your files live in your own workspace, encrypted at rest, and are not used to train AI models; see how to keep sensitive documents private with AI.
