Google Stack was a document-scanning and organization app developed by Google’s Area 120 incubator, aimed at helping users digitize, store, and manage personal documents such as receipts, bills, and records. Launched with the promise of simplifying paperwork through smart categorization and seamless cloud integration, Stack utilized Google’s advanced optical character recognition (OCR) and artificial intelligence to extract key details and sort documents automatically.
It offered features like secure backup via Google Drive, searchable content, and intuitive user experience, positioning itself as a modern solution to traditional filing cabinets. Though the app was eventually discontinued, it represented Google’s ongoing exploration into productivity tools powered by AI. This article explores the goals behind Stack, how it functioned, and what its short-lived journey reveals about digital organization trends.

What Was Google Stack?
Google Stack was a document-scanning and organization app developed by Google’s experimental division, Area 120. Designed to streamline paper management, Stack allowed users to capture physical documents—such as receipts, invoices, and bills—and convert them into searchable PDF files. The app automatically categorized these files into intuitive folders, making retrieval quick and efficient.
Stack was free to download and available exclusively to Android users in the United States. However, its independent functionality was short-lived. In late July 2024, core features from Stack were integrated into the Google Drive app. Google officially ended support for Stack beginning the week of September 23, 2024, effectively sunsetting the standalone app in favor of a more unified document management experience within Drive.
Key Takeaways
- Backups were stored on Google Drive, ensuring secure, cloud-based access to all scanned documents.
- Launched in March 2021, Google Stack was a document digitization and organization app developed by Google’s Area 120 incubator.
- The app is no longer available on the Google Play Store; it was free to use but limited to Android devices in the United States.
- Powered by artificial intelligence, Stack scanned physical documents and saved them as PDFs, automatically sorting them into customizable categories.
- Users could search their documents intuitively, using keywords such as store names, due dates, or specific amounts.
How Google Stack Worked
Google Stack launched on March 30, 2021, as a product of Area 120—Google’s in-house incubator under its parent company, Alphabet Inc. (NASDAQ: GOOG, GOOGL). Designed to simplify document management, Stack allowed users to scan, organize, and store personal paperwork using their Android devices.
When available on the Google Play Store, users began by photographing a document using the app. Stack would then scan the image, automatically enhance it, assign a title, and suggest a suitable category—or “stack”—based on the document’s content. Users could also import existing PDFs or images stored on their devices for the same treatment.
Predefined stacks included categories like Bills, Receipts, Banking, Medical, Tax, and Travel. Users had the flexibility to rename files, reassign them to different stacks, create custom categories, or even assign one document to multiple stacks. Visual editing tools allowed cropping, color adjustment, and other enhancements, although Stack handled much of this automatically. Reviewers praised its smart OCR capabilities—especially its accuracy when processing even crumpled or low-quality documents.
Google Stack: Key Strengths
While document-scanning apps were nothing new, Google Stack stood out for its advanced organizational capabilities. What set it apart was its use of artificial intelligence to “read” documents and intelligently categorize them—automatically extracting key details like dates, merchant names, totals, and document types to suggest appropriate storage locations.
This smart data recognition also powered flexible search functionality. Users could locate documents by searching for specific text, such as a store name, a bill’s due date, or a monetary amount. Full-text search within documents made it even easier to retrieve information without manually sorting through files.
Another major advantage was Stack’s integration with Google Drive. Users could choose to automatically back up their scanned documents to the cloud, ensuring ongoing access via desktop or laptop—even after discontinuing the app or following its official sunset in late September 2024.
Reactions to Google Stack
Google Stack was generally well-received during its time on the Play Store, earning a strong 4.7-star rating from 6,680 user reviews as of April 2024. Users frequently praised its ease of use and practical utility, with comments like “Use this app daily” and “Amazing app” reflecting the overall positive sentiment.
However, some users voiced frustration with the app’s artificial intelligence, particularly when it miscategorized documents or failed to read certain formats accurately. Others noted occasional difficulty when switching between front and rear cameras during scanning.
A handful of reviewers also raised concerns about data privacy—specifically regarding Google’s broader business model and handling of user information. In response to such concerns, Google pointed to its Workspace privacy commitments, stating that customer data and service usage information would never be used for targeted advertising.
