Coeus for Researchers

Your literature, your notes, your words. All searchable from one place.

Drop a PDF, a DOI link, a YouTube talk. Ask questions across everything you’ve collected.

The problem

Sound familiar?

PDFs in a folder called "to read." A Zotero library you stopped updating. Browser tabs from six months ago you meant to come back to.
You remember reading something relevant but can’t find it. You re-read the same paper twice.
Your notes from different sources don’t talk to each other. Synthesis requires going back through everything by hand.

How Coeus helps

Here’s what changes.

Turn any source into a note

Paste a URL, upload a PDF, drop a YouTube link. Coeus pulls the text and creates a note. The content is now searchable and queryable alongside everything else.

Ask across your whole collection

"What have I read about measurement invariance?" "Which papers mention that methodology?" Coeus searches across everything you’ve captured and answers from your actual sources.

Your notes stay yours

Everything is plain Markdown in a folder you own. Back it up to git. Open it in any editor. It doesn’t disappear if Coeus does.

Connect the AI you already use

Use Claude, ChatGPT, or a local model. The AI reads your notes, not the internet. Answers come from what you’ve actually collected, not from a hallucination.
