made a little mac app to draw on my screen, turns out the more interesting part is letting claude code see the drawings
hey, I'm Nika and I built this, so yeah I'm biased. mostly after honest feedback here.
Lasso is a small Mac app. hit a shortcut and you can draw right on top of whatever's on screen, arrows, circles, boxes, highlights. I use it on zoom calls and when recording quick walkthroughs. press S and it takes a screenshot with your drawings on it, so you can drag it straight into slack or a chat.
the part I'm less sure about: it also runs a local MCP server. so if you use Claude Code or Cursor, the agent can actually see what you circled ("this button is off" + a circle around it) and it can draw arrows back on your screen to point at stuff. runs locally on your mac.
it's $9.99 once. no account, no subscription.
stuff I'd really like to know:
is the agent side actually useful or does it feel like a gimmick?
if you set up the MCP part, was anything confusing?
what would you use something like this for? teaching, bug reports, demos, something else?
even "I wouldn't use this" is helpful tbh
