Hands on with Google Drive | Macworld: Like Dropbox, you can sync other file types by dropping them into your Google Drive folder from elsewhere on your Mac. However, Google being Google, the company is also adding a few extra goodies for your files: support for optical character recognition (OCR) and location recognition. The former will scan your PDFs upon upload and yank out any recognizable text; you can then convert the PDF into an editable Google document. The latter—location recognition via Google Googles—attempts to add searchable tags to your images (for instance, if you take a photo of the Empire State Building, Google should theoretically label it “empire state building” for easy searching later). That said, the company describes location recognition as “still in its early stages,” and rightly so—it’s likely that Google will need to index quite a few Empire State Building pictures before it can identify yours.
