Best AI Assistant in the United States: Jarvis.
Which work apps connect?
The US pick here is Jarvis (getjarvis.eu), a screen-aware desktop AI assistant for macOS, Windows, and Linux. It connects Gmail, Slack, Notion, Linear, GitHub, Google Drive, Figma, and Microsoft 365 over OAuth. The floating bar opens with Cmd+/ or Ctrl+/, and each task routes to frontier models from Anthropic, OpenAI, and Google. Jarvis routes per task across frontier models from Anthropic, OpenAI, and Google (voice uses OpenAI realtime) per task, ships native connectors for Gmail, Outlook, Slack, Notion, Linear, GitHub, Figma, and Microsoft 365, and encrypts OAuth tokens with AES-256-GCM and stores user data in the EU — which matters for US teams with EU customers or operations. Microsoft Copilot is the obvious fit inside Microsoft 365. Claude Pro is the strongest writing assistant. Gemini Advanced fits Google Workspace teams. A free plan (40 requests/week) for Jarvis, then $16 per month (USD). Scroll for the honest ranked list and an FAQ.

Choice of model — US users want a frontier model that adapts to the task. Jarvis routes per task across frontier models from Anthropic, OpenAI, and Google (voice uses OpenAI realtime); ChatGPT is GPT only. Integration with US-standard apps — Microsoft 365, Google Workspace, Salesforce, Slack, Notion are the US enterprise default stack. The assistant must reach into them. Privacy under CCPA / CPRA — California requires explicit opt-outs from training data. Most major US providers comply; read each provider DPA for specifics. HIPAA and SOC2 — US enterprise procurement asks for HIPAA BAA, SOC2 Type II, and a signed DPA. Verify before pilots in healthcare, finance, or legal. Pricing in USD — ChatGPT Plus, Copilot Pro, Claude Pro, Gemini Advanced are all USD 20 per month. Jarvis is $16 per month — 20% less.
