Jarvis is a native desktop app (macOS & Windows). The interface you see is a web layer; underneath runs a compiled Rust core that does all the real work and owns your OpenAI key.

• The key lives only in the OS keychain (macOS Keychain / Windows Credential Manager) — never in the app bundle, never in logs, never sent anywhere but OpenAI on your own account.
• The web layer talks to the core through small typed calls and receives streamed results back — it never touches the key or calls OpenAI directly.
• Everything is local-first: your tasks, notes, finance, memory and audit log stay on your machine.

• Chat streams replies token-by-token from gpt-4o-mini. Transient network/rate errors retry automatically with backoff.
• Voice is hands-free: press the mic once, just talk. Local voice-activity detection ends your turn after ~1.3s of silence, transcribes it, Jarvis answers and speaks each sentence as it's generated, then keeps listening. Start talking over it to interrupt (barge-in).
• Short-term memory — the recent back-and-forth of the current conversation is always in context.
• Long-term memory — durable facts (names, preferences, projects) are saved with the memory_save tool and injected into every future conversation, so Jarvis remembers across sessions and restarts. Manage them in the Long-term memory section above.
• Conversation archive — every chat is saved in full. The clock icon in the chat header opens the history: browse all past conversations, search across them by any word, reopen one to keep talking, delete, or export them all to JSON. The + starts a fresh conversation.

Jarvis acts through tools. When you ask for something, it calls the right one and the matching panel updates live:

• Tasks/boards — add, move, list, create boards.
• Goals & tracker — set goal progress, log habits.
• Knowledge vault — save and search notes.
• Finance — record expenses, summarize the budget.
• Research — queue a topic to search & summarize.
• Memory — remember/forget durable facts.

Jarvis — and any agent you grant the Computer / shell capability — can operate this machine: open apps and folders, find files, run builds, deploy.

• Nothing runs on its own. A command appears as a card showing the exact text; it executes only after you click RUN (30s timeout, output shown inline).
• Every run and denial is written to the audit log (in Computer control), tagged with the agent name when an agent issued it.
• The Computer control toggle is the kill-switch — turn it off and execution stops instantly, everywhere, including agents.
• Agents are scoped assistants you build with their own prompt, tools and knowledge. They run in their own window with their own memory.

• Usage & cost tallies real tokens from every response and estimates spend per month. Set a monthly budget and Jarvis warns you as you approach it.
• Updates — the app checks for new signed releases and offers a one-click “Update & restart”. Each update's signature is verified before it installs.
