You're at a client site, on their laptop. You need to sign a contract. The laptop has no PDF software installed beyond the default viewer. IT won't let you install anything.
Not a problem. Open a browser; you have everything you need.
Browser is the only requirement
Modern browsers — Chrome, Edge, Safari, Firefox — handle Flint's full toolkit. No install, no admin rights, no IT ticket. Open browser, navigate to Flint, work.
For IT-locked machines, this is the killer feature. The toolkit lives on the web, not on the device.
Sign in for personal context (optional)
If you have a Flint account, signing in syncs saved signatures, recent documents, and preferences. If you don't, anonymous use works fine — every tool is available without an account.
For temporary use on someone else's machine, anonymous mode means no traces left behind.
Cloud storage covers the file layer
Your `/Inbox`, `/Working`, `/Archive` folders should sync via cloud storage (Drive, Dropbox, OneDrive, iCloud). Sign into the cloud provider, your files are there.
For truly portable setups, even logging into your email gives you access to attachments from anywhere.
Limitations to know
Browser-based tools can't access local files until you upload (or drag-drop) them. For files only on a USB stick, you'll need to copy to the local machine first.
Otherwise: full capability, anywhere. The toolkit you've trained yourself on is genuinely portable.
FAQ
What about kiosks or restricted machines?
If a browser works and you can drag files in, Flint works. Some highly locked-down kiosks block file uploads — in those cases, no tool works.
Is it safe to use on someone else's machine?
Flint processes files locally in your browser. Files don't upload anywhere. For shared machines, log out of any cloud storage and clear the browser cache when done.
What if my client requires DocuSign specifically?
DocuSign also works in the browser. The principle is the same: pick browser-based tools so you have them anywhere.
What about Chromebooks?
Browser-based tools work natively on Chromebooks. Often better than on Windows or Mac for this category of work.
Your PDF toolkit lives in the browser; the browser is everywhere. Open Flint on any machine and feel the portability.
