Is there some project that the opensource world is missing that you think it needs?
Google earth
I’m always surprised that, for as widely used as PDFs are, there doesn’t seem to be any real alternative to Acrobat for editing existing PDFs.
The PDF was/is a closed-source propriety file format.
Tax software. It’s the only reason I keep a windows VM.
I considered an accounting SaaS once. Only once though. The amount of constantly changing regulations would make it a very high maintenance project.
This is niche, but I really want a good FOSS screenwriting software that can rival Highland. There are some options like Trelby and others (because the Fountain syntax makes interchangeable screenplay files possible) but right now none of them are as good as Highland. A good alternative could let me finally leave Apple
If you really wanted to leave the Apple eco-system, it would most likely be possible to run macos in an emulator (kvm/qemu) on a pc and most likely the software too.
Open source language learning only has Anki. Everything else is in an enbryonic stage.
There are so many low hanging fruits. Add-on to look up words in subtitles and add it to Anki. Luo dingo clone that’s a bit less tedious (without having to write so much of your native language). Clozemaster clone (unless someone knows how to set up Anki to do this)
forget me not, i think on f-droid may be an option. it’s fairly easy to make data files for, and you could easily ask your favourite llm to wrap some data into the format.
