Vireo Your private AI assistant.

It plans your day, researches, works through your files and gets things done, with the model running on your own Mac. Nothing goes to a cloud chat service.

Illustration of the Mac app

An assistant, not just a chat window

Keeps track of your day, on your Mac.

Each service is off until you turn it on, and anything that changes your stuff waits for your OK.

Calendar & reminders

Ask what's on today, find a free hour, add or move events and complete reminders, using the accounts already in Calendar and Reminders.

"Find me an hour for a call on Thursday."

Morning briefing

Pick a time and days, and get a short summary of your calendar, reminders due and the weather as a notification that opens a chat.

"Brief me."

Scheduled tasks

Have it do something on its own, once, every weekday or before each meeting. Results arrive as notifications, and changes wait in Approvals.

"Every weekday at 8, tell me what's on my calendar."

Quick Ask & voice

A small panel over whatever app you're using. Type, hold a shortcut and talk, or say "Hey Invurse". Speech is recognised on your Mac.

Select text › Services › Summarize with Vireo

Memory & your own context

It remembers what you ask it to, and can search your calendar, reminders, contacts and the folders you choose to answer questions about your life.

"When is my dentist appointment?"

Approve before it acts

You see the plan, each step and the results as they happen. Changing events, sending a message, deleting files and running commands all ask first.

Tick "Don't ask again" for the safe ones.

A real Mac app, not a browser tab

Still great at the actual work.

Chats that stay organized

Search your history, pin favourites and sort chats with tags and collections. Export any conversation to Markdown or PDF.

Files and images

Attach PDFs, Word documents, CSVs, text and images, then ask about them. The document stays in context across follow-ups.

Research and code

Search the web and read sources. Inspect project files and Git changes, and run tests, builds and linters for Swift, Python, Node and more.

Use it from other apps

Turn on the OpenAI-compatible API, and editors, scripts and tools that work with OpenAI or LM Studio can use your Mac's model.

Mac, iPhone, iPad and soon Windows

One Mac does the thinking. Every device can ask.

Your Mac runs the model and keeps your chats. Pair your iPhone or iPad with a one-time code, and they connect to it over your home network, not through anyone's servers.

  • A native Windows app is coming soon, built from the ground up for Windows.
  • Same assistant everywhere: calendar, reminders, memory and tasks all run on your Mac.
  • You stay in charge. Network access is off until you turn it on, and you can unpair any device at any time.

How it works

Up and running in three steps.

  1. Install Vireo

    Download the app and open it. It sets up everything it needs automatically.

  2. Choose your model

    Vireo checks your Mac's memory and storage and recommends a model that fits. Models download once and stay on your Mac.

  3. Start working

    Chat, attach files, research and build, all running locally on Apple Silicon. Pair your other devices whenever you like.

Privacy, control and real work

Modern AI without giving up your data.

Always on your Mac

  • The AI model and everything it processes
  • Your conversations and chat history
  • Files and images you attach
  • Memory, settings and service keys (in your Keychain)

Online only when needed

  • Model downloads from Hugging Face, during setup or when you add a model
  • Web research, only when you use it. Search queries go to your chosen provider; your conversation history does not.
  • Update checks against GitHub releases
  • Your other devices connect to your Mac over your local network

No cloud servers that see your chats. No analytics. No training on your data.

FAQ

Frequently asked questions

Is Vireo the same app as InvurseChat?

Yes. InvurseChat is now called Vireo. It's the same app from Invurse Studio with a new name.

Which Macs does Vireo work on?

Any Mac with Apple Silicon (M1 or newer) running macOS 14 or later. 16 GB of memory is recommended; more memory lets you run larger, more capable models.

Is there a Windows version?

A native Windows app is in development and coming soon. Get in touch if you'd like to hear when it's ready.

Does it work offline?

Yes. Once your model is downloaded, chat and file features work without an internet connection. Only web research needs to be online.

Where is my data stored?

On your Mac. Your chats are saved as files there, and you can delete any conversation at any time.

Which models can I use?

Google's open Gemma 4 models and Qwen models, run with Apple's MLX framework or llama.cpp. You can also search Hugging Face for any MLX or GGUF model, or add models you already have.

Can the AI change my files or calendar without asking?

No. Deleting, renaming or exporting files, running commands, changing events and sending messages all wait for your approval. You can choose "Don't ask again" for some kinds of action, but running commands and deleting always ask.

How much does it cost?

Nothing. Vireo is free to download and use.

Modern AI, rooted in your own machine.
