PocketShadow: Truly Private AI

Ever wish you could use AI without wondering who's reading your conversations?

PocketShadow is a private AI assistant that runs entirely on your Android phone. No internet connection required for chatting, no account, and no conversations sent to a cloud AI service. Just you and your AI, offline.

🔒 PRIVATE BY DESIGN

PocketShadow processes your prompts locally using Google's Gemma language model. Your conversations stay on your device.

• No INTERNET permission
• No account, sign-in, or email required
• No analytics, tracking SDKs, or advertising
• No conversations uploaded to cloud AI servers
• Chat history excluded from Android's automatic backup

Privacy is built into how PocketShadow works.

⚡ AI THAT RUNS ON YOUR PHONE

Powered by Google's LiteRT-LM runtime, PocketShadow runs the Gemma model directly on your phone's CPU or GPU.

• Responses stream as they are generated
• Chat without mobile data or Wi-Fi
• Use it on a plane, underground, or away from coverage
• No cloud AI subscription required

Response speed and quality depend on your device, the model, and the complexity of your request.

💬 AN ASSISTANT FOR EVERYDAY IDEAS

• Brainstorm personal ideas without uploading your prompts
• Draft messages, notes, and journal entries
• Think through questions and explore different perspectives
• Get offline assistance while traveling
• Discuss sensitive topics while keeping conversations on your device

For workplace use, follow your organization's device and data-handling policies.

🎨 MAKE IT YOUR OWN

• Five themes: Dark, Navy, Forest, Light, and Warm
• OLED-friendly dark themes
• Smooth, streaming responses
• Swipe to delete chats, with confirmation
• Adjustable conversation context, including an unlimited message-count option

The unlimited option removes the message-count limit. The amount of text the AI can process remains limited by the model's text budget.

📂 YOUR HISTORY, YOUR CHOICE

• Automatic chat titles help keep conversations organized
• Search your history and return to previous chats
• Turn history off when you don't want conversations saved
• Saved conversations remain on your device
• No cloud history sync

🛡️ SIMPLE PRIVACY CONTROLS

PocketShadow does not request Android's INTERNET permission and does not send your chats to an AI server.

Keep your history locally, disable it for new conversations, or remove locally stored app data through Android's app settings.

📋 NO MANUAL MODEL SETUP

The Gemma model is included and delivered with PocketShadow through Google Play.

No separate model download, manual file transfers, or developer settings required. Once installation is complete, open the app and start chatting offline.

⚠️ AI DISCLAIMER

PocketShadow generates responses using a local language model. Responses may be inaccurate, incomplete, or misleading.

Do not rely on PocketShadow for medical, legal, financial, or other safety-critical decisions. Verify important information and consult a qualified professional when appropriate.

Your ideas. Your conversations. On your device.
