easl is a native Mac app with one infinite board per repository. Use terminal tiles (libghostty + zmx session persist) to open agent clis, open code tiles at exact lines with your language server, call graphs, a browser, notes, HTML pages they write, and full tldraw style drawing with shapes, arrows, etc.

Then, the magic is how you can point at anything. Hold ⌃⌥⇧⌘ (I, and many of you, already rebind this to capslock, as ‘hyper’) and click a box in a diagram, a DOM element on a browser or a paragraph in a note. Whatever you point at, it gets added to your next prompt as context.
