What tool/product do you wish existed?

A device which can detect every single electromagnetic tranmission on every frequency. So i'm visualising something which can pick up bluetooth, wifi, radio, ir etc etc and display it on a screen with as much information as possible. Maybe theres an app for it or perhaps the flipper device can do all of that idk. I think it would just be interesting to see all the activity going on around us.

A tool that takes my gap-ridden resume, calculates the best trajectory moving forward, and frames it in such a way that someone will actually want to hire me.

Memex, as proposed by Vannevar Bush, updated slightly for the modern era.

A proxy that sits between my browser and the internet, and records everything into a huge disk buffer (perhaps using GIT as a storage engine?). It would allow annotation of anything seen on top of the page, without altering the source. The default policy would be to then keep all the pages, images, etc.. for at least a year, and anything not annotated, bookmarked, or otherwise linked to could be safely purged.

You should be able to select a trail of documents, and create a zip file of everything needed to view them, so you can share your stuff with friends.

A gadget you fill with water and put in a microwave oven and the water gets turned into ice cubes.

- an universal messenger tool which integrates with all the messengers (whatsapp, telegram, signal, e-mail) - an open source ChatGPT voice interface which I can use easily for ongoing interactions. I want to do like "OK Google" and start asking questions and interacting. Additionally it could record all my daily conversations to get context on what I am doing. If it could create calendar events and todos and remind me on that - it would be perfect

I've often wished for a tool that seamlessly organizes my digital life across devices. Imagine an all-in-one platform that syncs bookmarks, notes, passwords, and files effortlessly.

While some apps come close, having a unified hub would save so much time and streamline my productivity.
