LocalMind: Offline AI Chat

LocalMind – Your Private AI Assistant, Right on Your Phone

LocalMind is an on-device AI chat app: it runs local LLMs (small language models) directly on your phone. Your prompts and the AI's answers are processed on your phone and are not uploaded to any AI server. Once a model is downloaded, you can chat with it completely offline.

Your chats stay on your device

Your conversations are stored only on your device. We do not collect your prompts, chats or AI responses. (The free version shows ads, and ads, crash reports and anonymous usage statistics use network services according to your consent choices.)

Works Offline

No internet connection needed for AI conversations. Download a model once and use it anywhere, anytime — on a flight, in the subway, or off the grid.

Multiple AI Models

Browse and download models directly from Hugging Face. Choose from a wide range of small language models including Gemma, Phi, Qwen, Danube and more. Pick the model that fits your device and needs.

Voice Input & Text-to-Speech

Talk to your AI assistant using voice input and listen to responses with built-in text-to-speech. A natural, hands-free AI experience.

Custom AI Personalities

Create personalized AI assistants (Pals) with different personalities, system prompts, and settings. Build a coding helper, a language tutor, a creative writer, or anything you imagine.

Prompt Templates

Save and reuse your favorite prompts with built-in prompt templates. Speed up your workflow with one-tap access to common tasks.

Benchmark Your Device

Test and compare AI model performance on your phone. See tokens per second, memory usage, and share results with the community.

Multi-Language Support

Available in English, Hebrew, Japanese, Chinese, Korean, Russian, French, Farsi, Indonesian, and Malay.

⏱Free and Premium

The free version includes 10 chats a day, 2 model downloads and 2 document analyses. After that, a short optional video ad unlocks each extra one. LocalMind Premium (monthly or annual subscription) removes all ads and these limits.
