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:
StatusWhat it means
ProcessingSputnik is working on this document. This usually takes a few minutes.
ProcessedDone. The document is fully analyzed and searchable.
StoredThe file is saved in your project but was not a type that could be analyzed. You can still download it.

If Something Goes Wrong

Occasionally a document can’t be processed. The status tells you why:
StatusWhat to do
Password-protectedRemove the password from the file and re-upload it.
Document is emptyThe file contains no readable content. Check that it’s the correct file.
Timed out — too largeThe file is too large for processing. Try compressing it or splitting it into smaller files.
Format not supportedThis file type isn’t supported. See Supported File Types.
Could not processSomething unexpected went wrong. Try re-uploading the file.
Failed documents are still stored safely in your project. You can download them at any time.
