Joanium · Productivity
Joanium is a local-first AI app that turns Windows into an AI command center. It works as a desktop AI assistant that chats, automates, and takes action across the files and tools you already use. It connects to 28 AI providers and more than 40 integrations, so you can ask a question, trigger a workflow, or schedule an agent from one window. Keys, conversations, and routines stay on your machine, and you don't need an account to start.
About Joanium
What Is Joanium
Joanium is a Windows desktop app that turns your computer into a single workspace for AI. Instead of juggling a chat tab, a notepad, and half a dozen browser windows, you get one place where a conversation can pull context from GitHub, your calendar, or your local files and then act on it. It sits somewhere between a chat client and an AI automation tool.
The core promise is ownership. You bring your own API keys, which is why people call it a BYOK AI app, and your data stays local. There's no mandatory sign-up either. That matters if you've ever worried about where your prompts and files actually go. Nothing is proxied through Joanium's servers, according to the company.
The tradeoff is scope. Joanium runs on Windows only, so Mac and Linux users are out of luck for now. And because you supply the AI keys, you're the one paying providers directly, which means the "free" label applies to the app itself rather than your model usage. That catches some people off guard.
Getting Started
- Download the Joanium app for Windows from the official site and run the installer.
- Open the app and connect at least one AI provider by pasting your own API key. You can pick from 28 cloud and local options.
- Link the tools you want the assistant to reach, such as GitHub, Notion, Jira, or your calendar.
- Ask your first question or describe a task, then let Joanium pull the context it needs and respond.
- Set up a scheduled agent or a mobile reply channel if you want it to keep working after you close the laptop.

Key features
28 AI Providers in One Window
Joanium connects to 28 AI providers, covering cloud services like Claude and OpenAI as well as local models through Ollama. You switch between them inside the same workspace instead of maintaining separate apps. Because it's bring-your-own-keys, you decide which provider handles which task and pay them directly.
40+ Tool and App Connectors
The app links to more than 40 connectors spanning Google Workspace, developer tools like GitHub, GitLab, and Vercel, and data sources such as arXiv, Reddit, and CoinGecko. Tools activate automatically when your prompt needs outside data, so you don't wire up each request by hand. Joanium says credentials stay on your device. No shared cloud vault. That's the whole point.
Scheduled Agents
You can run predictable automations on a schedule, or let an agent gather context and act when a task needs judgment. A daily operator, for example, can check repos, scan email, and post a brief to a channel you actually read. Why schedule instead of asking each time? Because some work should just happen. That shift is what makes Joanium more than an AI agent for Windows alone; it's the feature that moves it past a plain chat client.
Project-Scoped Workspaces
Chats bind to a workspace, which keeps files, terminal work, and git context in the same flow. Your repo effectively gains a memory: context from earlier sessions stays tied to the project rather than scattering across a chat log, which is exactly what you want when a bug you fixed last week comes back to haunt a new branch. If you work on several codebases, this is what stops the cross-talk.
Mobile Reply Channels
Telegram, Discord, Slack, and WhatsApp all connect, so you can reach the same assistant from your phone. You send a message and get a full response with tool access, not a stripped-down bot. The desktop stays the brain, and the chat app is just the doorway you happen to be standing in when you think of something worth asking.
Local-First Storage and BYOK
Keys, conversations, and routines live on your machine, and Joanium says it never proxies your data. There's no mandatory account, and the company describes the app as free and source-available forever. This is the privacy angle, and it's the main reason some people pick it over a cloud tool.
MCP Extensibility, Skills, and Personas
Joanium is MCP-extensible, so you can add capabilities beyond the built-in list. Skills and personas let you switch tone, domain, and depth without changing tools, turning the same assistant into a researcher, coder, operator, or reviewer. A community marketplace lets you download or publish these after signing in with GitHub.
Pros and cons
Pros
- Genuinely local-first: keys and conversations stay on your device with no mandatory account.
- Wide reach out of the box, with 28 AI providers and 40+ connectors ready from day one.
- Scheduled agents and mobile reply channels let work continue when you're away from the desk.
- Free, source-available app with BYOK, so you're not locked into a subscription.
- Project-scoped workspaces keep code, files, and context tied to the right repo.
Cons
- Windows only, so Mac and Linux users can't run it yet.
- You supply and pay for your own API keys, so model costs pile up separately from the app.
- The long feature list can feel overwhelming at first if you just want a simple chat.
Frequently asked questions
Yes, the app is free and described by the company as source-available forever. You still pay AI providers directly for model usage, since Joanium works on a bring-your-own-keys basis.
