Record your screen, point and speak — turn the session into a video prompt for Cursor, Claude Code, or Codex.
Key features
- Point-and-Speak Recording: Capture your screen while drawing and narrating so the agent gets both visual and voice context.
- Cursor / Claude Code / Codex Handoff: Drop the session directly into your existing agent — no prompt draft to write.
- MCP-Based Delivery: Sends frames and speech through MCP so the agent reads structured context instead of a raw video blob.
- Multi-Monitor Capture in One Take: Record app on one display and editor on another together in a single session.
- UI Markup Tools: Pen, rectangle, and text annotations mark the exact button or region you mean.
- Local-Only Processing: Runs entirely on-device on Apple Silicon — no upload, no login, no cloud.
- Fewer Tokens per Change: Structured video prompts reduce token load compared to pasting long written briefs.
- Free for Mac: No account, no paid tier — full functionality out of the box.
Best for
- UI Bug Report to Agent: Record a broken flow, circle the problem, and hand it to Cursor to fix.
- Design Review with Coding Agent: Show a Figma-to-code diff on-screen and dictate the required visual tweaks.
- Cross-App Debugging: Capture logs in one window and the failing UI in another, then let the agent reason across both.
- Refactor Requests: Highlight a specific component in the editor and describe the desired API change verbally.
- Onboarding a Junior Agent: Walk through a repo layout on video so Codex has context before making changes.
- Privacy-Sensitive Codebases: Prompt an on-device agent about sensitive UIs without any recording leaving the Mac.

Turns a smartphone video of an open trench into a centimetre-accurate 3D point cloud, CAD as-built plan and GIS-ready digital twin of buried utilities.
Key features
- Smartphone capture: Field crews record an open trench with a standard iPhone Pro — no specialist scanning hardware and no separate surveying appointment
- Centimetre-accurate point clouds: Reconstruction algorithms developed at ETH Zurich build a high-resolution 3D point cloud of the excavation from the video alone
- Standards-compliant CAD output: Generates as-built plans in DWG and DXF, with couplings and pipe runs identified and measurements simplified
- 3D digital twin and GIS export: Produces a model of the pipe route including building entries that drops into existing GIS systems
- Works without GPS: Captures basement sections and building entry points where GNSS-based surveying fails
- Immediate backfilling: Because capture takes minutes, trenches close right after filming instead of waiting on a survey crew
- Documentation in about 72 hours: Complete records arrive weeks earlier than conventional surveying, enabling prompt connection billing
- Third-party utility capture: Records crossing utilities and as-laid geometry as unbroken 3D evidence, replacing hand sketches
Best for
- A utility network operator documenting residential service connections without booking a surveyor for every site
- A contractor closing a trench the same day instead of leaving it open pending a survey appointment
- Capturing a building entry point in a basement where GPS-based surveying cannot get a fix
- A district heating project producing as-built DWG plans for regulatory sign-off
- Spotting a laying error in the 3D point cloud before backfilling, while the fix is still cheap
- Feeding as-built pipe geometry into a GIS system for long-term network maintenance planning
