Pinker is a desktop tool that lets you use keywords and topics to find any file on your computer similar to how you would search on eBay. Pinker always shows how many files match each of your topics, so you can quickly narrow down your search.
Pinker is so fast that you can browse topics and saved searches as if they were folders. You'll find that you can give up on maintaining rigid folder structures. No time consuming meta data tagging is required. Your data stays where it is, on your devices, on your own network.
Your data is safe with Pinker, simply because Pinker does not change your data in any way, does not transfer any data or any information to anywhere else. With Pinker your information stays on your computer.
