Share two screens

Two screens out. Nothing else.

Pick the two windows or displays your reviewer should see. Your other monitors never leave this machine. Video travels browser-to-browser; nothing is stored.

Your pen

Draw on a preview to point something out. Ink fades after 2.5 s. Right-click to drop a marker that stays.

Review markers

Typed pins from both sides that stay until resolved. Copy them as change requests for Claude or Cursor, with a sheet of screenshots to match.

No open markers
01

Capture

Choose exactly two windows or displays. Everything else stays private.

02

Send the link

One URL. Your reviewer clicks once and both screens open as real windows.

03

Draw together

Either side can circle, underline, point. Ink fades so nothing piles up.
