Some examples I'm currently thinking about are Roam, Notion, Muse, and Obsidian.
I'm especially interested in more touch/visual based tools for thought, rather than text-based tools.

1. Heptabase is interesting software.
2. Whiteboard feature of Diagrams.net is underrated.
3. Otter.AI is amazing voice to text transcription
4. SnagIt is useful to be able to easily screenshot almost anything

For example a VR memory palace[0].
We're in the early days of haptics but gloves like the ones in this video[1] will allow for more dimensions of touch based tools.
