Not sure if the /e/OS Android-compatible AOSP-based operating system on my phone qualifies as FOSS. Surely not Linux despite the kernel - neither does Android.
/e/OS comes with local offline non-cloud voice to text / dictation / speech transcription. How do I get this to other OSs?
It also comes with a slightly customised NextCloud (installable to many OSs), which is full of utilities: the usual cloud tools bundled with Apple, Google, and Microsoft OSs, except the constant surveillance.

(TLDR: /e/OS is open source, beginner friendly, and mostly being developed by a small French company)
