A Microsoft Copilot Alternative
That Runs Real Tools on Your PC

Tell Jarvis to summarise yesterday’s commits and it reads the git log. Ask which containers are unhealthy and it queries Docker. Ask it to turn the TODO comments in a directory into tickets and it opens Jira. Ask it to reply to a WhatsApp message and it sends the reply. Each call is visible and logged, and a multi-step request runs as one chain rather than a series of copy-and-paste prompts. This is the part a system-integrated chat assistant, however polished, does not do for a developer’s toolchain at the time of writing. The same agent answers by voice when you say the wake word, and it remembers decisions across sessions so you are not re-explaining your projects every morning.

Copilot runs on the models Microsoft chooses for it. Jarvis routes across 7+ AI providers — Claude, OpenAI, Gemini, Groq, OpenRouter, local Ollama models, and the Claude Code command-line tool — picking per request or honouring a prefix you type. You bring your own keys and pay each provider directly, with no token markup added.

Copilot is a cloud service: prompts are processed on Microsoft’s infrastructure under Microsoft’s terms, with whatever data protections your licence provides, and you should read those terms for your own situation rather than rely on a summary here. Jarvis is local-first. RELAXED, the default, sends prompts to the cloud model you chose with no redaction. GUARDED mode lets you use cloud models but strips credential-like strings such as API keys, passwords and tokens before each call. STRICT mode answers with local Ollama models only, though online tools such as web search still work. Memory stays on your disk, and API keys and integration tokens are encrypted with Windows DPAPI. The security page covers each mode in depth.

A Copilot alternative that works offline, with a local LLM

Copilot is a cloud assistant. Microsoft’s own Windows Insider post says the “Hey Copilot” wake word is detected locally, but “Copilot Voice responses require internet access and cloud processing.” On-device Windows AI features are tied to Copilot+ PCs, which Microsoft Learn describes as needing an NPU capable of more than 40 trillion operations per second. Jarvis’s STRICT mode instead runs any Ollama model on the PC you already own — for example OpenAI’s open-weight gpt-oss-20b, which Ollama lists as running with as little as 16 GB of memory.

A Copilot alternative for developers

Developers usually want an assistant that acts on their toolchain, not one that only describes it. In Jarvis, one request can:

1. read the git log and summarise yesterday’s commits,
2. query Docker for unhealthy containers and restart one,
3. run a shell command and read its output,
4. turn TODO comments into Jira tickets,
5. and post a status update to a chat thread — with every tool call logged.

A Copilot alternative that works with Gmail, not just Outlook

To be fair to Microsoft, Copilot on Windows is no longer Outlook-only: in October 2025 it added opt-in connectors for Gmail, Google Calendar and Google Drive, with natural-language search across them in the initial release. Jarvis goes further on the action side. It creates and updates Google Calendar events, and reads and sends mail over IMAP and SMTP with an app password you create — which works with Gmail, Outlook, iCloud or any other IMAP provider.

A Copilot alternative with no subscription

The basic Copilot app is free, but Microsoft’s paid consumer tier is now Microsoft 365 Premium at $19.99 per month, which replaced Copilot Pro in October 2025. Jarvis is a $9.99 one-time payment for lifetime access. You pay model providers directly for what you use, or nothing at all if you stay on local Ollama models.
