Modelbase: Local AI Chat & LLM
Private & Offline Assistant
Free
Your own AI, on your own iPhone.
Modelbase runs language models directly on your device. Ask anything, think ideas through, work with your documents and photos: it all happens on the phone in your hand, even with no connection at all. What you write is never sent to an AI service.
WORKS OUT OF THE BOX
A compact model is included, so your first chat starts right away. Want more? Download open models from Hugging Face in a tap: Qwen, Llama, Gemma, Phi, DeepSeek, Liquid LFM, SmolLM and more, including vision models that understand photos. Modelbase shows which models fit your iPhone's memory before you download.
PRIVATE BY DESIGN
• Offline: models run on the device, on a plane, in the subway, anywhere.
• Nothing leaves your phone: chats, memories and files stay with you.
• Temporary chats: ask without saving anything to your history.
SMARTER ANSWERS WHEN YOU WANT THEM
• Web search: turn it on and answers are grounded in cited sources you can open. No account, no API key.
• Deep research: a longer search across more sources for the questions that need it.
• Reasoning: watch the model think before it answers, with adjustable thinking effort.
• Built-in skills: weather, news, places near you on a map, recipes, math and unit conversion, translation, grammar fixes, questions about your calendar and reminders.
TALK, SHOW, SHARE
• Voice mode: a spoken conversation, hands-free, and you can interrupt by speaking.
• Dictation and read aloud: speak your message, hear the reply.
• Photos and files: attach images, take a photo, drop in PDFs and documents and ask about them.
• Markdown, code blocks and math formulas rendered properly.
MAKE IT YOURS
• Memories: tell Modelbase what to remember and it is added to your chats' instructions.
• Custom instructions and a system prompt per chat.
• Branch a conversation, archive chats, export a chat, search everything.
• Modelbase for Mac: the same app, native on Apple silicon, with a menu bar item and a quick chat bar. Chats and memories sync between iPhone and Mac through your private iCloud.
• Bring your own key: connect OpenRouter or a model server of your own when you want a larger model. Your key stays in your Keychain.
Speaks 15 languages: English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Simplified Chinese, Spanish, Turkish, Ukrainian and Russian.
Requires iOS 18 or later, or macOS 15 or later on Apple silicon. Larger models need more memory; Modelbase tells you what fits.
