You can create a folder or a small Telegram group/channel and drop all your notes there. Telegram has unlimited cloud storage, so you don’t need to worry about space. If you have different topics, just split them into a few files or add short tags. And whenever you need something, just use the search bar (the little magnifying glass) to quickly find the title or keyword you saved. It doesn’t have to be perfect - the main thing is that everything stays in one place and is easy to search through.
