Accessibility Permissions for AI Text Apps, Explained

You installed an inline AI editor and the first thing it did was ask for Accessibility permission on macOS (or to be allowed to read/control other apps on Windows). It sounds alarming — “allow this app to control your computer?” — and a lot of people stop right there.

The permission is legitimate and, for this kind of tool, unavoidable. But you deserve to know exactly what it grants, why the tool needs it, and how to tell a trustworthy implementation from a sketchy one. Here’s the plain-English version.

What the permission actually does

An inline AI editor’s whole job is to read the text you’ve selected in another app and write a replacement back into it. To do that, it has to reach across application boundaries — and operating systems deliberately make that hard, because reaching into other apps is exactly what malware would also want to do. So the OS gates it behind an explicit permission:

macOS — Accessibility (System Settings → Privacy & Security → Accessibility): grants an app the ability to read UI elements (including selected text) and send input (keystrokes, paste) to other apps. It’s the same permission screen readers, automation tools (Keyboard Maestro, etc.), and window managers use.
Windows — UI Automation / input access: Windows is less of a single toggle, but the tool similarly needs to read the focused control’s text and send input. It generally must run at a compatible privilege level with the target app.

Without this, the tool can’t see your selection or write back the rewrite — which is why every legitimate inline editor (and every screen reader, and every macro tool) needs it. It’s not a red flag; it’s the table-stakes permission for the entire category.

Why it feels scarier than it is

The macOS prompt is worded broadly — “control your computer” — because the capability is broad. But “can read selected text and send keystrokes” is precisely the capability an editing tool requires, and nothing more sinister is implied by the permission itself. The real question isn’t whether the permission is powerful (it is). It’s whether you trust the specific app you’re granting it to — because the permission can’t tell the OS “only use this for editing.”

That’s why which tool you grant it to matters more than the permission itself.

How to tell a safe implementation from a risky one

The permission is the same; what an app does with it varies. Look for:

A clear privacy/no-logging statement. The app can read selected text — does it keep any of it? A trustworthy tool says, plainly, that it doesn’t log or retain your text.
Transparency about what’s sent where. When you trigger a rewrite, your selection goes to an AI model. A good tool tells you whether that’s a cloud model, your own key (BYOK), or a local model — and only sends the selection you chose, not a running capture of everything you type. (See Is your AI writing tool leaking your work data?.)
It only acts on your trigger. The tool should read your selection when you press the hotkey — not continuously monitor your typing. There’s a big difference between “reads the selection on demand” and “watches everything.”
A real company / signed app. A signed, identifiable developer is accountable in a way an anonymous binary isn’t.
BYOK / local options for sensitive work, so you can keep text off third-party servers entirely.

If a tool has the permission but won’t tell you what it does with your text, that’s the red flag — not the permission request itself.

How to grant it (and fix it when it breaks)

macOS: System Settings → Privacy & Security → Accessibility → toggle the app on. If editing stops working after an app update, the most common cause is macOS silently revoking the permission because the app’s signature changed: toggle the app off and back on (or remove and re-add it) to restore it.

Windows: make sure the tool runs at a privilege level compatible with your target apps. If you run some apps as administrator, the tool may need to as well (Windows won’t let a non-elevated process automate an elevated app).

How EditSnappy handles this

EditSnappy needs the same Accessibility / input permission every inline editor does — there’s no way around it for a tool that reads your selection and writes the rewrite back. What it does with that access is the part that matters:

It reads your selection only when you trigger a rewrite, not continuously.
[[MISSING: confirm exact retention wording with Ken — homepage v1 and master-sales-copy §9 both flag the no-logging/no-retention statement as not-yet-finalized.]] The intended stance is no logging and no retention of your text.
For sensitive work, the intended BYOK / local-model options keep your text off third-party servers entirely (gated on the final pricing/tier decision, master-sales-copy §8).

The aim is to make granting the permission an easy yes: it does exactly what an editor needs and nothing you didn’t ask for. See how EditSnappy works.
