> in plain language

## You talk. It acts.

Simply state what you need in everyday language. Gotcha evaluates live device context and triggers the exact Android system operations required to complete your task.

`toggle_torch`

`set_volume`

`navigate_app`

> two copilot modes

## Monitor plans. Operator acts.

Gotcha runs as one of two copilot modes on your device. Switch modes instantly from the interface at any time.

“Inspect & Plan”

Reads screen context, inspects device state, and analyzes information. It cannot send messages, alter settings, or delete files — ensuring zero-risk inspection.

“Execute & Automate”

Performs direct actions across messages, calls, apps, media, and screen automation — fully bounded by explicit permissions you grant.

> visual feedback & permissions

## Clear permissions & visual mode indicators

In call mode, Gotcha gives clear visual ring indicators: a **Blue Ring** means it is reading the screen and performing foreground operations, while an **Orange Ring** signals background processing. Actions are protected across 4 permission levels so you are always in control.

- Tier 0–1Everyday PermissionsBattery, storage status, phone dialer, opening apps
- Tier 2Personal AccessCalls, SMS, calendar events, location, camera access
- Tier 3Device AutomationScreen touch automation, notification reading, device admin
- Tier 4Privileged AccessRoot shell actions (strictly fails closed on unrooted devices)

> accessible over any app

## The Assistive Ball

A floating companion accessible from anywhere on your phone. Long-press it — or just say *“Hey Gotcha”* — to start a push-to-talk voice call, where Gotcha sees your screen and acts on your behalf.

**Example:** Browsing Amazon and see a shirt you like on a model? Ask Gotcha to *“find similar shirts to the one worn here.”*Gotcha takes over the screen, searches the web, and presents matching products instantly.
