About this skill
Problem
Transferring files between phones, PCs, and tablets often means routing through a cloud service, using mobile data, compressing files, or configuring permissions across operating systems. When several devices are already on the same home WiFi router, a more direct option is local LAN transfer.
How It Works
Device Link brings file transfer to a local network: after starting the skill, the user opens the provided LAN IP, enters a 5-minute temporary code, and can then move original files between phone, computer, and tablet. Main capabilities include:
- Local transfer: about 10MB/s~50MB/s, without cloud upload or extra compression.
- Security controls: LAN-only access, MAC allowlist, temporary code, and automatic blocking of executable malicious files.
- Control: voice commands can start or stop the skill and view device lists or logs.
Boundaries
All devices must be on the same router WiFi, and the user must be able to reach the provided LAN address. Guest networks, AP isolation, or cross-subnet setups may prevent communication. It is not a public P2P service; expired codes require a new one. If the router restricts ports, DNS, or device-to-device access, router settings still need adjustment.
Use Cases
- After shooting product photos on a phone, send original images over the same WiFi router to a Mac for editing.
- While preparing meeting notes on a tablet, pull a PDF from a nearby laptop to review on the tablet.
- At a trade show with weak public internet, transfer Android logs and PC config files over one router LAN.
- At home, pull Android phone photos from a Windows PC without cloud upload or mobile data.
Best For
- Photography operations staff who need to move original phone shots to a Mac for editing
- Embedded test engineers who transfer device logs and configs offline at trade shows
- Home workers who handle meeting materials across Windows, Android, and tablets
- Freelancers who exchange original files among phone, tablet, and PC on the same WiFi
