Color Alerts makes it easy to receive alerts when your favorite colors are detected. Use the Capture button at the bottom center of the screen to save the color currently visible within the capture area. Once a color is captured, you can choose the alert or vibrate option you would like to hear or feel whenever the camera detects that color. Your saved colors can be viewed and managed by selecting the Saved Colors icon in the upper-left corner of the screen. From there, you can enable or disable individual colors, allowing you to choose exactly which saved colors you want Color Alerts to monitor. For more accurate color detection, Color Alerts provides several ways to fine-tune what the camera is monitoring. Adjust the zoom above the Capture button, change the size of the capture area using the control on the right side of the screen, or use the Custom Controls panel to fine-tune your color selection and detection settings. Once your color and detection settings are configured, simply position your device where you want it to monitor. When one of your enabled colors appears within the capture area, Color Alerts will notify you with your selected alert.

Shellcove does not sell model access or provide a hosted cloud account. Manage tasks from your phone • Browse native conversations and filter by Mac. Search loaded conversation text, tool output and filenames; load earlier messages when needed. • Return to questions, uncertain receipts and new replies, with device-local read state and direct links to the original content. • See actual run activity and get specific next steps for sign-in, quota or execution problems. • Save named instructions on this device, edit or append them to a draft, and import/export text-only copies. Instructions are sent only when you choose. • Start with your goal and editable task prompts; connection and execution states remain distinct. • Create a standalone conversation or organize work with optional Projects and Tasks. • Send instructions, follow replies and native tool activity, and request a confirmed stop. • Queue the next input and withdraw it before execution. Add immediate input where the native Agent supports it. • Read native business questions; answer remotely when the native client exposes a supported answer handle. • Inspect an uncertain submission by its original receipt instead of sending it again.

Pair with your own Macs Scan a Mac's QR from Computers. iOS connects directly to each paired Mac, with pinned TLS, client authentication and Internet relay fallback. Each phone can have its own credential and be revoked separately. Macs do not forward tasks to each other. The execution Mac must stay online and awake. Accepted work continues when you leave the phone app; live interaction needs a connection. Native Agent compatibility Configured native clients include Codex, Grok Build, OpenCode, ZCode and DeepSeek Harness. Support depends on the installed client and the capabilities shown for that Mac. DeepSeek connects through its official Desktop Gateway. A live question still owned by Desktop must be answered there. External ZCode desktop conversations remain history-only; managed CLI conversations support execution. Device tools and privacy Remote Desktop, Window Text, keyboard, mouse and clipboard tools remain in Computers → device details. Their Mac permissions are separate from Agent conversations. No Shellcove account, advertising or analytics. Drafts, downloaded files and caches stay on your devices. Model providers process submitted content under the native Agent's settings and their own terms; relays forward encrypted content and may process connection metadata.
