inv is a private AI assistant that runs on your own computer. Download the app, pick a model, and talk to it with no account and no cloud.

inv v0.2 agent, reasoning: medium
Does anything I type leave this computer?
Only web searches, and only while you have the internet switch on. The model, your chats and your files stay on this machine.
What do I need to run you?
A Mac with Apple silicon and at least 16 GB of memory, and about 10 GB of free disk. A Windows version is on the way.

./get-inv --os=mac

models, one is enough to start

cat requirements.txt

Memory is what matters most. The model has to fit in memory together with your conversation, and longer conversations take more: about 0.15 GB per 1,000 tokens of context on top of the model.

model	computer	download	memory, min	recommended	longest chat

macOS: Apple silicon (M1 or newer) and macOS 14 Sonoma or later. Intel Macs are not supported. Windows: Windows 10 or 11, 64-bit; an NVIDIA graphics card with the listed video memory, or a slower CPU-only mode.

cat install.txt

Download inv for macOS and one model above.
Open the app zip and drag inv into Applications.
Open inv. The first time, macOS says it can't verify the developer, because the app comes from this site rather than the App Store. Click Done, then open System Settings > Privacy & Security, scroll down, click Open Anyway next to inv, and confirm. macOS only asks once.
Double-click the model zip, then move the folder it makes into inv's models folder:
```
~/Library/Application Support/inv/models/
```
In inv, open models folder in the model menu takes you straight there.
Pick the model in inv's model menu. The first load takes about a minute.
Optional, for running C++ code: open Terminal and run
```
xcode-select --install
```

sha256sum --check

Each download lists a SHA-256 fingerprint. To confirm a file arrived complete and unchanged, compare it with:

shasum -a 256 ~/Downloads/inv-v0.2-agent-mlx-8bit.zip          # macOS
certutil -hashfile %USERPROFILE%\Downloads\inv-app.zip SHA256   # Windows
