Best AI Overlay for Mac in 2026

Updated 2nd of July 2026 · 3 min read

Mac overlay landscape

Several macOS apps describe themselves as "AI overlays" in 2026, with different goals: invisible-to-capture overlays for proctored exams, productivity overlays for everyday work, and accessibility overlays for screen-reading. The right pick depends on what you are trying to do.

LDBypass is the only Mac app that sets the system-level window-privacy flag, making the overlay window invisible to ScreenCaptureKit, getDisplayMedia, and CGWindowList enumeration. Raycast AI, Granola, BoltAI, and similar productivity tools render normal windows that ARE visible to capture - useful for daily work, useless for proctored exams. For accessibility (read-aloud, summarize-page), Voiceflow and Apple's built-in tools dominate. We are biased: this article is on LDBypass' site. The bias is rooted in capability - the privacy flag is what makes the screen-capture invisibility work, and other overlays do not set it.

Key points

LDBypass: invisible to screen capture (proctored exam use case).
Raycast AI: hotkey-launched chat for everyday productivity (visible).
Granola: meeting notes, transcript summarization.
BoltAI: chat with multiple providers in one keyboard-driven interface.
Apple's built-in AI (Apple Intelligence): summary, rewrite, generative emoji.

How it works

 1.  LDBypass                      invisible to screen capture
 2.  Raycast AI                    hotkey-launched, visible window
 3.  Granola                       meeting notes, transcript
 4.  BoltAI                        multi-provider chat
 5.  Apple Intelligence            built-in, system-wide

Common questions

Why is LDBypass the only one with screen-capture invisibility?

Most overlay tools do not set the macOS per-window privacy flag because their use case is productivity, not stealth. We set it explicitly because it is the entire feature.

Is LDBypass paid?

It has a free trial (24 hours) plus paid tiers ($8 for 24h, $39 for 7d, $89 for 30d). Pricing is on the download page.

Can I use Raycast AI during a proctored exam?

You can run it, but its window will appear in screen captures. For proctored exams that record or share your screen, that defeats the purpose.
