HN: big-arrow-on-the-screen lets AI agents draw arrows, boxes and text on your display

franze · hn · 2026-10-09

Developer franze shared a small open-source tool on Hacker News: big-arrow-on-the-screen, which lets AI agents paint big arrows, boxes and text directly on your screen.

The idea is useful when agents need to guide human attention during demos, screencasts or tutorials — pointing at "click here" or highlighting a UI element visually. The project is open source on GitHub and worth a look for developers building agent-to-human interaction or presentation features.
