Lasso for Mac
Circle, highlight and point at anything on your Mac while you present, teach or explain. Press esc and it’s gone.
The problem
Whether you’re presenting, teaching or helping a teammate, pointing with a cursor only gets you so far.
A small arrow is easy to miss on a shared screen, so “this one, here” lands on no one.
Capture first, then open an editor, find the pen, export, paste. By the time it’s sent, the conversation has moved on.
Extra windows, stolen focus, and ink that stays behind after you’re done.
How it works
Lasso puts a transparent canvas over everything on your Mac — only while you need it.
Over any app, on any display.
Circle, highlight, point or number what matters.
Your drawing disappears and your screen is back to normal.
Great for
A circle on the screen says more than a paragraph of directions — whoever, or whatever, is on the other end.
Make this card match the other two — same padding, same number size.
With AI agents
Circle the part of a web page, design or doc you’re talking about, press S, and drag the screenshot into Claude, Cursor or ChatGPT. The agent sees exactly what you see.
In meetings, online or in the room
Circle, highlight and point while you talk — on a call, in a demo, in front of a class. No one has to hunt for your cursor.
this one — can it go out Thursday?
On it.
With a colleague or friend
Mark the exact spot, press S, and drop it in Slack or Messages. “The second one in the list, the one that says…” becomes a circle. No app on their end? Send a link.
Screenshots
Mark up your live screen and press S. The shot waits in the corner with every circle, arrow and highlight: drag it into a chat, copy it, or save it where you want.
No editor. No export.
Want to trim it? Click the shot to crop it or add more. The toolbar never shows up in the shot — just your screen and your drawing.
Drawing tools
Draw freehand around anything — your strokes come out smooth.
Mark a line without covering it up.
Arrows and lines that land exactly where you aim.
Numbered steps that count up as you click.
Also included: text, rectangles and ellipses, a laser pointer, an eraser, and eight colors.
Pages & whiteboards
Start a fresh page — or a whiteboard — without losing what you drew. Swipe back and it’s all still there.
Drag the page or click a tab.
Thoughtful details
Slides, code, video calls and full-screen apps.
No Dock icon and no windows to manage.
Press esc and your screen is exactly as it was.
Press S after drawing. It waits in the corner to copy, save, share or edit.
Leave a drawing up while you keep working.
A native app that feels at home on macOS.
Free. Opens from your menu bar and stays out of the way until you need it.
A free screen annotation app for Mac. Press ⌥⇧A and a transparent canvas covers your screen: circle, highlight, point at and number things in any app while you present, teach or share your screen. Press esc and it’s gone.
Yes. Download it, drag it to Applications, done. No account, no trial, no card.
Any Mac with macOS 14 Sonoma or later, Apple silicon or Intel. The Liquid Glass toolbar needs macOS 26; everything else is the same on macOS 14 and 15.
Yes. Lasso draws on your screen itself, so your marks show up in Zoom, Google Meet, Microsoft Teams and screen recordings — share your whole screen rather than a single window. Nothing to install on their side.
Yes. Claude Code, Claude Desktop, Cursor and other agents on your Mac connect to Lasso over MCP to see your screen with your drawing on it, read the screenshots you take, and draw arrows, highlights and numbered steps to show you where to click. When an agent needs you to decide something, it writes the question right on the window it's about, and you answer by clicking a number, typing a reply, or drawing. Press V while drawing and you can talk it through instead: say what you mean as you circle things, and Lasso hands the agent your words with each mark placed where you said “this”. Lasso asks before an agent’s first call, and the connection never leaves your Mac. Settings → Agents has the setup to copy.
Yes. Swipe to a whiteboard or blackboard page that goes on forever: scroll with two fingers to move around, pinch to zoom, ⇧1 to fit everything in view. Swipe back and your screen and drawing are still there.
Lasso is signed with an Apple Developer ID and notarized by Apple, so it opens like any other Mac app — no warnings, no workarounds.
Drawing needs none. Screenshots read the pixels on your screen, so the first one asks for Screen Recording. Talking a brief through for your agent asks for the Microphone and Speech Recognition — your voice is turned into text on your Mac and never sent anywhere. You can skip any of them and keep drawing.
Nowhere until you say so. Each one waits in a small stack in the corner: copy it, drag it into another app, or save it to the folder you pick. Share a link and it’s encrypted on your Mac first, so only people with the link can open it — for 24 hours.
Quit Lasso from the menu bar, then drag it from Applications to the Trash. That’s all of it.
