Add your research

Crux is most valuable when it works from your evidence. Everything you add is parsed and indexed so Ask and search can cite it precisely.

Upload files

Add documents, spreadsheets, and transcripts to your project:

• Documents — PDF, Word, PowerPoint, plain text.
• Spreadsheets — Excel and CSV.
• Transcripts — interview and meeting transcripts are especially rich material for highlights and synthesis.

Crux extracts the text, splits it into chunks, and creates embeddings so the content becomes searchable and available as Ask context. Larger files may take a moment to finish indexing. See Uploading research for the full details.

Import URLs

Paste a URL to pull a live page into your research. Crux reads the content so it can be cited alongside your files — useful for competitor sites, published studies, and your own product.

Connect Google Drive and other sources

On paid plans you can connect Google Drive and import documents directly, keeping your source-of-truth files where they already live. See Google Drive & Figma for setup.

Email counts as evidence too: connect Gmail or Outlook and set per-project filters so only the threads that belong to this project come in. See Work with Gmail and Outlook.

Where research appears

Everything you add shows up in the Research tab as a File item (or the relevant item kind). Open an item to read it, highlight passages, and ask questions in context — Ask knows which document you have open. To get through a long source quickly, run Analyse & Label on it and review the highlights it proposes.

Why indexing matters

Because sources are indexed rather than merely stored, Ask answers cite the specific passages they drew from under Sources. That is what makes an answer checkable rather than plausible.
