Localsend is a good one to try out. Works with all devices and is pretty fast. It does however require an app to run.

For something you can run off the web on PC you can try pairdrop. This doesn’t require an app to work on PC. Haven’t tried it without the app on mobile so not sure if it will work on there via web.

I prefer Localsend over pairdrop due to local send being completely server less and all local.

I have a discord DM to myself that I use.

Oh, posted this before I read the rest of your message lol. Nvm.

Best thing I’ve used in forever.

Depending on what I want to do, I used a combination of Unified Remote and LocalSend, both of which are available for Linux. With Unified Remote, I can control my PC on my home network. So if I want to copy over a URL, for example, I could open notepad and paste it remotely from my phone's clipboard (or type it manually), or I could open a new tab on my PC's browser and paste the URL so it's open and ready for me the next time I'm at my PC. I can sit downstairs on the couch and check the status of a project upstairs, open and run new programs upstairs, etc.

My only two complaints are that I need to be at the PC to handle admin messages like "Are you sure you want to install this program?", which I guess is a safety feature but it's still annoying. And secondly, I really wish they had an easier way to toggle between left- and right-mouse-click, it gets annoying.

To send images, actual files or even folders, I use LocalSend. It does require that you click Accept on the device you're sending to, but I can use Unified Remote to do that, and then save the files to wherever I want to (or accept the default).

This may be less streamlined than other options, but what I really like about it is that I can complete a task and then not have to think about it again. I don't have to go back to my desktop and download or save anything, I've already done it, the job's complete. The only exception is when I've put a new URL into my browser, but that's generally because I wanted to look at it on my (much larger than my phone's) desktop screen.

Anyway, it works nicely for me; I hope you find a solution that works for you!

Signal. I use it anyway so it’s not an extra “bloated” app and I know all the secrets I send over the app are encrypted.

If you use a password manager, most have a notes feature that works well too.

I’ve been working with this issue for along time. Trying to find something platform agnostic and works with vpns.

App wise, I suggest Localsend for files

Information wise, I suggest Saladroom although there are several alternatives as well like ToffeeShare and ShareDrop

I mostly use Signal though, as it’s the simplest at hand app which fairly reliably makes it accessible to my various devices… With the downside of storing it.

I usually just use an email draft for cross platform transfers. MacOS/iOS handle this pretty much automatically and Linux has options (KDE Connect) but it sounds like you’re on Windows.

Does Phone Link (built into Windows) work for your needs? I don’t use Windows often but I know they’re trying to make something sort of like the other OS’s syncing systems. Not sure how good it is.

I use Beeper to aggregate messaging from various platforms and for easy availability of text messages on my PC. It has a specific “Note to self” section that I’ve found useful for messaging myself.

At its core, Beeper is just a Matrix client with some pre-packaged bridges for common services (including SMS, MMS, RCS messages). You could probably do the same thing with an Element client.

I recently found out about patchbay. it’s the bare minimum pubsub tool. no dependencies, you can use it with just curl.

that said, it’s not in any way secure. if someone guesses the url you’re using, they can see your messages.
