Offline AI Chat: MemoryAI

Facchinits

About this app

MemoryAI — an AI assistant that lives on your phone and works without internet.

• Ask questions, write, and summarise your documents — by typing, or by talking hands-free
• Your chats stay on your phone: no account, no ads, no subscription
• Kid Mode with parental controls: a PIN, a content filter and a locked model

Download one AI model once (0.3–4 GB, best over Wi-Fi), then use it anywhere: on a plane, abroad, with no signal. Works on devices with 4 GB+ RAM.

🔒 Complete Privacy
Run powerful AI models directly on your phone. Your conversations, documents and memories stay on your device: no AI servers, no login required. The app sends only anonymous diagnostics and usage data, never the content of your chats.

🧠 AI Features
• Chat with AI — multi-turn conversations that keep the whole chat in context, up to the model's limit
• Agent Memory (optional) — turn it on in Settings and the AI remembers what you tell it, in your own words, stored locally on your device; view, edit or delete memories any time. Requires an embedding model
• Chat Search — search and filter your conversations by title or message
• Continuous Voice Mode — fully hands-free: speak naturally, and the AI listens, responds, and speaks back without tapping
• Voice Input — speak instead of typing with on-device transcription
• Text-to-Speech — listen to AI responses read aloud, or enable auto-speak for hands-free use
• Document Analysis (RAG) — import PDF, TXT and MD files and ask questions about them
• Image Understanding — analyze photos with Vision AI models; select multiple images at once
• Chat Templates — 20 pre-built AI personas (code helper, writing coach, tutor, and more)
• Benchmarking — measure model speed (tokens/sec) directly on your device
• Context Window Display — see current vs. max token usage, so you never exceed the model's limit

🔧 Power User Features
• Import custom GGUF models — bring any compatible model from HuggingFace
• Dual engine — Gemma (MediaPipe / LiteRT) + llama.cpp; choose the backend that fits your needs
• HuggingFace Token Management — save and manage your token for seamless gated model downloads
• Model parameters — adjust temperature, top-k, top-p, max tokens per model
• Pause & Resume Downloads — control large model downloads to save data or battery
• Backup & Restore — save your chats and settings to Google Drive

👨‍👩‍👧 Kid / Safe Mode
• PIN-protected parental controls
• Content filter blocks inappropriate words before they reach the AI
• Model Safety Checks — automatic warnings to prevent unverified imported models from running in Kid Mode
• Locks the active model — child cannot switch or change settings
• Age-appropriate AI responses, guided by a safety prompt
• Parental Unlock — temporarily access settings and documents from the chat screen without disabling Kid Mode

📱 Works Everywhere

• No ads, no subscriptions, no in-app purchases

Built by Facchinits — privacy-first AI for everyone.

What’s new

• Tools: a plain sum or a question about today's date is answered exactly, in your language, in an instant.
• A Thinking switch in Model Parameters for the models that reason: off, answers come in seconds.
• Backup: no size limit in memory, sizes in KB, iCloud upload confirmed.
• The model page keeps its Download or Delete button in view.
• A model that crashed the app is not loaded again by itself; on 3–4 GB phones hopeless loads are refused with the figures; imported models say why they fail.
