Stealth
Read full descriptionHide full description
Stealth is an AI assistant that runs entirely on your iPhone. Your words, photos, recordings and files are processed on the device and stored encrypted. There's no account, no cloud, no analytics, and no ads. TALK, SHOW, ASK β’ Chat with Apple Intelligence or a downloaded open model (MiniCPM, Granite, Gemma or Qwen), running on the iPhone's own chip. β’ Voice mode: a hands-free conversation with natural on-device speech. β’ Show Stealth: point the camera and ask. It answers in a few words. β’ Open it from the Action button, Control Center, the Lock Screen, widgets or Siri. REMEMBERS WHAT MATTERS β WITH YOUR CONSENT β’ Stealth can remember your preferences, projects and people, and only brings them up when they're relevant. β’ Review, pin or delete any memory. YOUR FILES AND RECORDINGS β’ Import PDFs, notes and text; Stealth knows every file you added, answers from them and cites the passage. β’ Share pages, text, photos and PDFs from any app straight into Stealth. β’ Private recorder: record a meeting or lecture, get a live transcript and a summary with action items, then ask about it later. It keeps recording with the screen locked. GETS THINGS DONE β’ "Remind me to call mom tomorrow at 9", "add dentist Friday 3pm", "set a 10 minute timer". You confirm each one first. β’ "What's on my calendar tomorrow?" is answered from your calendar, on the device. TRANSLATE, OFFLINE β’ Translate text, signs and menus through the camera, photos, and face-to-face conversations, on your iPhone. β’ Uses Apple's on-device translation, or a downloadable translation model (Hy-MT2 or TranslateGemma, 55 languages including Romanian), never the chat model. β’ Translated text appears right over the original in photos and the live camera. OFFLINE MAPS FOR HIKING AND OFF-ROAD β’ Download a region once (Romania available now): streets, every trail and track, marked hiking routes, terrain shading and contour lines, all offline. β’ Trails coloured by difficulty, tracks by grade, 4Γ4-only tracks highlighted. β’ Find the nearest water, shelter, mountain hut, peak or help without signal. β’ Record hikes and drives with distance, climb and time; import and export GPX. β’ 3D: fly over your route on real terrain, with an elevation profile. COMMS: TALK WITHOUT A NETWORK (OPTIONAL) β’ Nearby mesh: message people around you over Bluetooth, relayed phone to phone, with no signal. Works with the bitchat app too. β’ Online via Tor: end-to-end encrypted messages to your contacts anywhere, always routed through Tor. β’ SOS with your position to everyone nearby. Off until you turn it on; no account or phone number. WORKS WITH NO SIGNAL β’ Survival Core (optional download): 23 validated field guides on first aid, water, food, shelter, navigation, building, power and radio. Answers cite the page. β’ Wikipedia Medicine (optional): 58,000 medical articles as offline text. β’ Field Kit: an emergency screen with first-aid cards, GPS coordinates, compass, sunrise and sunset, and an SOS flashlight. PRIVATE BY DESIGN β WE NEVER COLLECT YOUR DATA β’ Stealth collects no data at all: no account, no servers, no analytics, no ads, no tracking. β’ AES-256 encryption for every chat, memory, file and recording. β’ Face ID lock. β’ Network ledger: see every download Stealth has made, with the bytes measured. Stealth goes online only to download a model, pack or map you chose, or for Comms if you turn it on, always through Tor. Answers can be wrong and aren't professional advice. In an emergency, contact emergency services when you can.
