Shellcove · Cloud Agent turns your own Macs into private Agent execution hosts. Use iPhone or iPad to start work, continue a native conversation, follow progress and bring original files back. Each task stays on one Mac; different tasks can run on different Macs. Your Mac runs the work The native Agent keeps its conversation, context, model settings and tools. Shellcove handles remote access, delivery receipts, state and recovery. Use your existing supported Agent and its account or plan. 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. Send material. Keep the original result. Upload documents or photos, up to four files and 10 MiB per file. Find materials and returned files together, with source messages and file versions. Save returned originals with size, version and digest checks, or open them in another app. Preview supported images and play videos. Document originals open in the other apps you choose. 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. Requires iOS / iPadOS 16+, macOS 13+, matching Shellcove 1.6 clients and a configured supported native Agent. Mac companion and setup: apps.zhizuzhefu.com/shellcove.

TigerText is the easiest way to add alt text to photos on iPhone — and it's now completely free. Point it at any photo and TigerText writes a clear, accurate description of what's in it. The description is saved into the photo's own metadata, so it travels with the image when you post or send it. Mastodon, Bluesky, and any other app that reads standard image metadata will pick it up automatically. Everything happens on your iPhone. No internet connection. No account. No ads. No tracking. WHY ALT TEXT MATTERS Alt text is how a photo becomes readable to someone using a screen reader. Without it, an image is just "photo" — no content, no context. Writing it by hand for every picture is real work, and that's why so many images go undescribed. TigerText does the first draft in seconds so you can post with a description instead of without one. FULLY OFFLINE, GENUINELY PRIVATE TigerText runs a vision-language AI model that ships inside the app. Your photos are never uploaded, never sent to a server, and never seen by anyone but you. It works on a plane, in a basement, or with your phone in airplane mode — because there's nothing to connect to. Privacy here isn't a policy promise. It's how the app is built. There is no server to trust, because there is no server. BUILT WITH THE COMMUNITY IT SERVES TigerText was shaped by feedback from blind and low-vision users, and it's designed to be used entirely with VoiceOver — not merely to pass an accessibility checklist. Every control is labeled, every action is announced, and the whole flow works without ever needing to see the screen. That includes the parts people usually forget: you can hear the description read aloud before you save it, edit any wording you disagree with, and know immediately whether a photo already has alt text. WHAT YOU CAN DO • Describe any photo in your library, one at a time or in batches • Hear any description read aloud before you commit to it • Edit the wording — it's your description, the AI just drafts it • See at a glance which photos already have alt text and which don't • Add descriptions to animated GIFs without losing the animation • Send photos straight from the Photos share sheet • Share a photo with the description already embedded FREE, AND STAYING THAT WAY Every feature is free forever. There is no paid tier, no subscription, no in-app purchase, no locked content, and no ads. TigerText uses the Qwen2-VL model (Apache 2.0) running through Apple's MLX framework. The bundled model is verified with a SHA-256 integrity check on every new version, so you always run the genuine, untampered model. A NOTE ON THE DOWNLOAD SIZE TigerText is a big download, and that is the whole point. The entire AI model lives inside the app instead of on a server somewhere. Nothing is streamed, nothing is fetched, and none of the work happens on someone else's computer. Download it once and it works forever. On a plane. In a tunnel. In a basement with no signal. On a trip with no data plan. There is no server to go down, no API to get shut off, no subscription to lapse, and no spinner while something uploads. Your photos are never part of anybody's dataset, because they never leave your phone. Most apps that describe images send your pictures away to do it. TigerText carries the whole thing with you instead. That's what makes TigerText a true offline utility: the big download is the feature. Install it once over Wi-Fi, and describing a photo never needs a network again.
