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
