Tell once.
Done forever.
Your autonomous desktop AI that reads emails, organizes files, and runs automations — so you never have to.
Done! Here's what I did:
5 unread emails — 2 urgent, 3 FYI
Downloads organized: 12 PDFs moved to Documents, 8 images to Pictures, 3 ZIPs to Archives
Built for how you actually work
Nina adapts to your role. Pick your persona and she optimizes for your workflow — no setup required.
“Summarize emails, draft replies, organize invoices”
Nina reads your inbox every morning, categorizes emails by urgency, drafts professional replies, and tracks your invoices — all automatically.
“Find TODOs, run tests, set up CI reminders”
Nina greps your codebase, runs shell commands, monitors builds, and creates scheduled reminders for code reviews and deployments.
“Track competitor prices, write social threads”
Nina monitors competitor websites for changes, generates content ideas from trending topics, and drafts multi-platform social posts.
“Morning briefing: emails, calendar, action items”
Nina prepares your daily briefing at 8am — email triage, upcoming meetings, pending tasks. One glance and you know your day.
Your data never leaves your computer
Nina runs locally. Your conversations, files, and emails stay on your machine. We can't see them even if we wanted to.
