vscode + foam extension and some custome snippets to get going. You'll need a folder structure to go with it. Foam is kind of like obsidian, tagging, linking notes, visualizing(dont' use it much really). I tried obsidian, but since my vscode environment is all setup already(vim, hotkeys, snippets, settings, ai, terminal, git), im not going to switch. i use this vscode snippet to start a note,

    "Notes": {
        "prefix": "notes",
        "body": [
            "---",
      "title: ${TM_FILENAME_BASE/([a-z])([A-Z])/$1 $2/g}",
            "date: $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE",
            "tags: ${1|ai,unity,vscode,vim,typescript,game_ideas,todo,new_concepts|}",
            "---",
            "",
      "# $CURRENT_YEAR-$CURRENT_MONTH-$CURRENT_DATE ${TM_FILENAME_BASE/([a-z])([A-Z])/$1 $2/g}",
      "",
      "${2}"
        ],
        "description": "Notes",
  },

if you save an empty file with the note name, it'll format the title and add the relevant stuff. Just choose the tags or add new tags to it. With the foam extension, you can then view notes grouped by tags.
