Best Ways to Sync Files, Clipboard and Passwords Between Your Phone and Computer Without a Cloud in 2026 (Local Network, No Account)

The best way to get files and copied text between your phone and computer without a cloud in 2026 is Off Grid AI. You pair your iPhone or Android with your Mac, Windows or Linux computer once, and files and copied text go across your own network, encrypted, with no account. Sync comes with Pro, paid once, and the same key also covers meetings, memory, dictation and Reflect. Your passwords stay on the computer, so if you need them on your phone too, add KeePassXC.

Sync sharing in Off Grid AI Desktop. You choose what sends on its own, what asks first and what this computer accepts.

How we ranked

1. How much of the job one tool does. Files, copied text and passwords. None of these tools does all of it.
2. Automatic once it's set up. Your changes follow you without pressing send every time.
3. No cloud account. Your data goes device to device, encrypted, and there's no account to make.
4. Your devices. It runs on the phones and computers you already have.

The ranking at a glance

Rival facts come from each tool's own site, docs or README, linked in its section. "Not listed" means the tool's own pages don't list it.

1. Off Grid AI

What it is. Off Grid AI Desktop (OGAD) for Mac, Windows and Linux, and Off Grid AI Mobile (OGAM) for iPhone and Android. With Pro, you pair them once by scanning a QR code or typing a pairing code. After that they sync over your local network, or straight to a nearby Apple device, and traffic between paired devices is encrypted.

Files you attach to chats, images you generate and models you download all follow you. You can send any other file by hand, and pick Off, Ask or Auto for screenshots and downloads on each device. Copied text goes both ways, and OGAD keeps a searchable clipboard history on the computer. Android won't let apps read the clipboard in the background, so on the phone you send text with Copy to Off Grid AI in the selection menu. Your AI chats and projects stay the same on every paired device too.

Best for. You want files, copied text and your AI chats in one app on your phone and computer, with no account and no server in the middle.

Price. The apps are free. Sync, Clipboard and Vault come with Pro, at $119 once or $7.99 a month, for up to 5 devices.

The catch. Your passwords don't reach your phone. The Vault is encrypted with your master password plus a key tied to that computer, and it stays there. It can fill website logins and hold private files on that computer, but OGAM has no vault. Sync has no internet route either, so when you're away from home your devices wait until they share a network again. On a Mac you need Apple silicon, on Linux an x64 machine with Ubuntu 24.04 or newer, and Pro needs internet once to activate.

2. KDE Connect

What it is. A free, open-source app that links your phone to your computer. Its user guide lists file and link sharing, browsing the phone from the computer, phone notifications on the desktop, text messages, media control and clipboard sharing for text. Its download page lists Linux, Windows, macOS, Android and iOS. If you're on GNOME, GSConnect is a separate app that speaks the same protocol.

Best for. You want your phone's notifications and texts on the computer, for free.

Price. Free. The site says "Free to use. For any purpose. Forever."

The catch. The guide says clipboard sharing "does not work with images". On Android 10 and later you press Send Clipboard by hand. On iPhone, clipboard, notifications and the background connection are limited, and copied text only goes from phone to computer. Both devices need the same network unless you set up a VPN or Bluetooth, and it doesn't sync passwords.

3. Syncthing

What it is. It keeps folders the same across your devices, all the time. Its site says "There is no central server that might be compromised", encrypts all traffic with TLS and works "over LAN and over the Internet". When your devices can't reach each other directly, public relays pass the data along, still end-to-end encrypted, though a relay sees your IP address and how much traffic flows.

Best for. You want whole folders the same on several computers, at home or away. It's also the usual way to get a KeePassXC file onto your phone.

Price. Free and open source under the MPL-2.0 licence.

The catch. The official Android app is gone. Its repository says "This app is discontinued", and it was archived on 3 December 2024. On Android you can use the community Syncthing-Fork app from F-Droid, and on iPhone there's Mobius Sync, a third-party app. Syncthing doesn't list clipboard sharing.

4. LocalSend

What it is. A free app that sends files and text to devices near you. Its site says it "Works completely offline" over local Wi-Fi, uses HTTPS with end-to-end encryption and needs no account. You can get it on Windows, macOS, Linux, Android and iOS.

Best for. You need one file or a block of text on your phone, or on a friend's laptop, quickly.

Price. Free and open source under Apache-2.0.

The catch. You send every transfer by hand. Your folders and clipboard don't stay in sync, and it doesn't handle passwords.

5. KeePassXC

What it is. A free, open-source password manager for Windows, macOS and Linux. Its site says "no data is stored on remote servers". Your passwords live in one encrypted .kdbx file, and you decide where it goes.

Best for. You want your passwords on your phone and computer with no cloud account. Keep the file on the computer, copy it across with Syncthing and open it on the phone in a KeePass app.

Price. Free under GPLv3.

The catch. Its docs say "We don't have our own mobile app". They send Android users to KeePassDX and KeePass2Android, and iPhone users to Strongbox and KeePassium. It has no built-in sync, and the docs suggest a shared cloud folder, so Syncthing is how you skip the cloud. Edit on one device at a time so you don't end up with two copies that conflict.

Which one should you pick

• You want files, copied text and your AI chats in one app, on your computer and your iPhone or Android: Off Grid AI.
• You want your phone's notifications and texts on the computer, free: KDE Connect, or GSConnect on GNOME.
• You want whole folders the same everywhere, even away from home: Syncthing.
• You only send a file now and then: LocalSend.
• You need your passwords on your phone without a cloud: KeePassXC with Syncthing and a KeePass app on the phone. Off Grid AI can't do this today, because its Vault stays on the computer.

FAQ

What is the best way to sync files and clipboard between my phone and computer without a cloud?
Off Grid AI Pro. You pair your iPhone or Android with a Mac, Windows or Linux computer once, and files and copied text move over your local network, encrypted, with no account. If you want it free, KDE Connect is the pick.

Can Off Grid AI sync my passwords to my phone?
No. The Off Grid AI Vault stays on the one computer where you made it. If you need passwords on your phone without a cloud, keep them in KeePassXC on the computer, copy the file with Syncthing and open it in a KeePass app on the phone.

Do these tools need the internet?
Off Grid AI, LocalSend and KDE Connect move your data over your local network. Syncthing works there and over the internet, through relays that only pass on encrypted data. You need internet once to download the apps and models and to activate Pro.

Is Syncthing still on Android and iPhone?
Not as an official app. The Syncthing Android app was discontinued in December 2024. On Android you can use the community Syncthing-Fork app from F-Droid, and on iPhone there's Mobius Sync, a third-party app.

Which tool shares the clipboard both ways?
Off Grid AI and KDE Connect both send copied text. Phones limit background clipboard reads, so on Android you send text by hand in both apps. KDE Connect on iPhone only sends from the phone to the computer.

What does syncing your phone and computer without a cloud cost over three years?
KDE Connect, Syncthing, LocalSend and KeePassXC are free, so they cost nothing over three years. Off Grid AI Pro is $119 once, and the same key covers meetings recorded without a bot, dictation into any app, Memory of your screens and docs, and Reflect.
