How to Upload

Open your project and go to the upload page. You have two options:
  • Drag and drop files directly onto the upload area.
  • Click to browse and select files from your computer.
You can upload entire folders by clicking “Upload Folder.” This is useful when you have case files organized in directories — Sputnik processes every file in the folder. The maximum file size is 200 MB per file. Up to 5 files upload simultaneously. See Supported File Types for the full list of accepted formats.

​
What Happens After Upload

Processing starts automatically. Depending on the file type, Sputnik:
  • Extracts text from PDFs (including scanned documents via OCR)
  • Converts Word, Excel, and PowerPoint files to searchable text
  • Transcribes audio and video files
  • Reads images directly with AI
Then AI analysis runs on every file to extract a title, summary, document date, people, organizations, and key events. Tags are created automatically based on the content.

Document Status

After uploading, each document shows a status:

If Something Goes Wrong

Occasionally a document can’t be processed. The status tells you why:
Failed documents are still stored safely in your project. You can download them at any time.
