Build Your Own Jarvis With Claude
A Jarvis is not one app. It is a dashboard, a brain, a voice layer, and carefully chosen connectors that start read-only.
Dashboard
A local or hosted page that shows the daily briefing, active metrics, calendar, tasks, and assistant state.
Brain
Claude Code or Claude web routines handle reasoning, file reading, tool use, and connector calls.
Voice
Voice input can come from built-in dictation or browser speech APIs. Voice output can be wired through a TTS provider.
Connectors
Add Gmail, calendar, analytics, revenue, social, or ads one at a time. Test read-only before writes.
Subagents
Use specialists for research, inbox, ads, content, or engineering so the main assistant stays clean.
Routine
Schedule the daily brief only after the manual version works reliably.
Safety rule: start with read-only access. Anything that sends email, posts, spends money, changes ads, or updates customer data needs human approval.
