Computer ↔ Computer
Transfer files between two computers, minus the rituals
Two computers on the same desk shouldn't need a USB stick shuttle, an email to yourself, or a cloud round-trip to swap a folder. BIShare moves files directly between any two computers — Windows, Mac, or Linux, in any combination — over the network they already share. One side can even use a plain browser.
The USB-stick shuffle, and other rituals
The stick means finding it, hoping it's formatted right (NTFS won't write on a Mac), and walking it back and forth. Network shares mean permissions, workgroups, and a settings safari on both machines. Email caps you at 25 MB, and the cloud sends your file on a round trip through a data center just to cross the room. Every one of these is a workaround for the same missing feature — computers talking to each other directly. That's the feature.
How the direct route works
Both machines, one tool
Install BIShare on Windows, Mac, or Linux — any mix. A machine you can't install on (a locked-down work laptop, a friend's PC) can send and receive from a browser tab instead.
They find each other
On the same network, the two computers appear to each other automatically. Drag a file — or a whole folder — onto the other machine, and it lands end-to-end encrypted at Wi-Fi speed, with nothing stored anywhere in between.
No router? Improvise one
No shared network around — a move-in day, a client site? A phone hotspot counts as a network, with zero internet needed. Both computers join it and the transfer runs exactly the same.

Computer-to-computer transfer, answered
Can I transfer between two computers without a router?
Yes — any phone's hotspot works as the meeting point, with no internet required. Both computers join the hotspot and transfer directly. On a normal home or office network, the router does the same job.
Does it work between Mac and Windows?
Yes, in both directions — and Linux too, in any combination. Every platform runs the same protocol, so a Mac ↔ Windows transfer behaves exactly like PC ↔ PC. No SMB shares, no drivers, no format juggling.
Can I send an entire folder?
Yes — drag a folder in and it arrives as a folder, structure intact. For a whole user profile's worth of data, send in a few large batches so each one is easy to verify on arrival.
How fast is it?
As fast as the network between the machines — typically 40–50 MB/s on ordinary Wi-Fi 5, more on wired or newer Wi-Fi. A 10 GB folder is minutes, because it crosses the room instead of crossing the internet twice.
Is it safe to use on an office network?
Transfers are end-to-end encrypted device-to-device, so other machines on the network see only ciphertext. Nothing is uploaded to a server, and the receiving computer has to explicitly accept each incoming transfer.
