The best open AI models, running in your pocket.
Modelbase runs open models on your iPhone, iPad and Mac. Private by default. Works without internet.
Free · No account needed
Chat in private.
No internet needed.
Modelbase runs the model on your own device, with Apple's MLX. What you type is processed right there, so it works in airplane mode, on a train, anywhere.
No account and no sign-up. Your chats stay on your device, and sync only through your own iCloud.
The best open models.
One tap away.
Choose from more than 50 open models by Qwen, Google, Liquid AI, Meta, Microsoft, IBM, Mistral and others, tuned for Apple silicon.
LFM 2.5 comes with the app, so you can chat the moment it opens. Want a bigger model? Connect OpenRouter with your own key, or a server on your own network.
Check the facts.
Every source linked.
Ask about today's news or anything you need to get right. Modelbase searches the web, reads the pages, and answers with numbered sources you can open.
Searches go straight from your device to DuckDuckGo and the pages it finds. Turn web search off any time.
Snap a photo.
Ask what it is.
Vision models look at your photos right on your device. Point the camera at a plant, a menu or a sign, and ask.
The photo never has to leave your phone for an answer.
Speak your question.
Hear the answer.
Turn on voice mode and just talk. Modelbase listens, answers out loud, and waits for your next question.
Your speech is turned into text on your device.
Weather, stocks, places.
Answered as live cards.
Ask about the weekend's weather, a stock or a restaurant nearby, and get the numbers on a live card instead of a paragraph.
Each card says where its data comes from.
Everything a chat app should do.
On your device.
iPhone, iPad and Mac
One app on all three, built for Apple silicon.
Synced through iCloud
Your chats follow you, through your own iCloud. Or turn it off.
Documents and PDFs
Drop in a file and ask about it. It is read on your device.

Thinking models

Your own assistants

The app speaks yours, from Spanish and German to Japanese.
What is Modelbase?
In short.
Modelbase is a free app for iPhone, iPad and Mac that runs open AI models on the device itself, with Apple's MLX. Chats with a model on your device need no internet connection and no account, and they stay on your device.
It works like the chat apps you know, but the model runs on your iPhone, iPad or Mac instead of on a server.
