Obsidian is the better fit when…
- You write and link notes by hand, and love it
- You want plugins, graphs and canvases
- You also work on Windows, Linux or Android
iki vs obsidian
Obsidian proved that a folder of markdown can hold a whole mind. IKI agrees about the files and adds the reading, transcribing and answering, on your iPhone.
Obsidian is a markdown editor and a thinking tool: links between notes, a graph, canvases and a plugin ecosystem that turns it into almost anything. It’s free, commercial use included, local-first, and never asks for an account unless you buy Sync or Publish. Out of the box it doesn’t read what you save. There’s no transcription of voice or video, no text from screenshots and no answers. IKI covers that half. Because both use plain markdown, they can share a folder: keep IKI’s library in iCloud Drive and open it as a vault in Obsidian on your Mac.
