Lasair vs LowLighter
Verdict (August 2026): LowLighter is cheaper; Lasair is the more invisible architecture. LowLighter hides an app window with a capture flag, a flag class that is unreliable against ScreenCaptureKit on macOS 15 and later. Lasair renders on a dedicated GPU plane at the display level, with no window and no flag, from $19.99/month with a free trial.

Where LowLighter wins
LowLighter is cheaper. Basic costs $9.99 per month and Pro costs $14.99 per month, both below Lasair Plus. The free tier allows 15 answers a day, which is enough for light use. Its region-select capture lets you point the AI at exactly the area you want, and its Stealth Type feature types answers out at a human pace. If monthly price is the deciding factor, LowLighter is the cheaper product.
Why system-level rendering matters
LowLighter hides its overlay the way most overlay apps do: it sets a content protection flag on an ordinary window and asks the operating system to leave that window out of captures. That design has two limits. The flag is a window property, so other software can enumerate windows and check for it. And the flag depends on operating system behavior the vendor does not control. Public documentation shows this class of protection is unreliable against ScreenCaptureKit on macOS 15 and later.
Lasair takes a different path. The overlay is drawn at the display level, on its own GPU plane, as part of the Windows display pipeline. There is no app window and no flag. Because rendering sits at the display level, one hotkey reads whatever is on screen, in any application, with no region selection.
