Turn Mac screen annotations into searchable Markdown with Lasso

A Lasso voice brief pairs what you say with what you draw on your Mac. Lasso transcribes speech on the device, puts numbered references to your marks in the transcript and saves a searchable brief.md file with screenshots when screen capture is allowed.

Record visual feedback while drawing

Allow Microphone and Speech Recognition when prompted. On macOS 14 or 15, turn on Dictation in System Settings. Allow Screen Recording if you want annotated screenshots and close-ups in the brief.

  1. Open the app, design or browser page you want to discuss. Press Option–Shift–A (⌥⇧A) to start drawing in Lasso.
  2. Press V or click the waveform button. Speak while you circle a control, underline text or point with an arrow.
  3. Press V again to finish. Lasso copies the brief, so you can paste it into an AI chat, issue tracker or design review.

Example transcript with numbered screen annotations

In this example, you circle the Export button while asking for a UI change, then underline the error in the status panel. The transcript puts [1] and [2] where you made those marks.

What they said:
“Move the Export button [1] into the toolbar, and keep the ‘Export failed’ message [2] visible until it’s dismissed.”

Find and search your local voice briefs

In Finder, choose Go → Go to Folder and open ~/Library/Application Support/Lasso/Briefs. Lasso keeps the latest 20 voice brief folders. Each has a brief.md transcript and mark descriptions. When available, display-N.png shows the annotated display and mark-N.png shows a close-up of a mark.

Search the Markdown in a text editor for a control name or error message. To keep feedback with the work, copy the transcript and attach the relevant PNGs to the ticket or review.

Let a connected agent read the latest voice brief

With Lasso’s local MCP server connected in Claude Code, Claude Desktop or Cursor, ask the agent to read your latest Lasso voice brief. The get_brief tool returns the most recent brief from the current app session. To share an earlier brief, paste its saved Markdown and attach the images you want the agent to see.
