Uploading research
Supported file types, how parsing and indexing work, and tips for getting the best AI context from your files.
Everything you upload to Crux is parsed and indexed so AI skills and search can use it as evidence.
Supported sources
- Documents — PDF, Word (.docx), PowerPoint, plain text and markdown.
- Spreadsheets — Excel (.xlsx), CSV.
- Transcripts — interview/meeting transcripts as text or documents; audio transcript formats are supported for imported transcriptions.
- Web links — website nodes unfurl and capture page content.
- Google Drive (paid plans) — see Google Drive & Figma.
- Figma (coming soon) — design-frame import is on the roadmap; see the same article for updates.
What happens on upload
- Parsing — Crux extracts the text (including PDF text layers and Office document content).
- Chunking — long documents are split into overlapping chunks.
- Embedding — each chunk gets a vector embedding so semantic search and skills can retrieve exactly the relevant passages.
- Preview — a preview is generated for quick reading inside the app.
Indexing runs in the background; very large files may take a minute before they're fully searchable.
Files on the canvas
Uploads live in the Uploads panel and can also be placed as file nodes on the canvas. Connecting a file node to your analysis nodes tells skills to treat that file as upstream context.
Tips for better AI output
- Prefer text-first files. Scanned image-only PDFs have no text layer to extract.
- Split monster documents. Several focused files retrieve better than one 300-page compendium.
- Name files meaningfully. File names appear in search results and citations.
Storage
Each plan includes a storage allowance (from 200 MB on Free up to 50 GB on large team plans by default). Deleting a project removes its files, previews, and embeddings.
