- Deploy web apps or frontends to Vercel from mobile
- Manage Supabase backends and databases while away from a workstation
Quartz
datarockets
AI-native email client for Mac that sorts your inbox and drafts replies in your voice, running entirely on-device.
Key features
- On-Device AI: Inbox sorting and reply drafting run locally on Apple Silicon, so email is never sent to external AI providers.
- Importance-Based Triage: Auto-categorizes every message by importance you define and the system learns over time, surfacing what matters and collapsing FYI, Icebox, and Noise.
- Voice-Matched Drafts: Learns your writing style, sender relationship, and thread context to draft replies that sound like you rather than a template.
- Local Encryption: Mail is encrypted on your device with keys only you hold, and the company has no servers that can read it.
- Gmail Integration: Connects to Gmail accounts and has been independently audited under Google's Cloud Application Security Assessment.
Best for
- Inbox Overload: Professionals who get high message volume let Quartz triage by importance so they focus only on mail that needs attention.
- Privacy-Sensitive Email: Users who handle confidential correspondence keep AI processing fully on-device instead of uploading mail to cloud AI services.
- Faster Replies: Drafting routine responses in the user's own voice to cut time spent writing repetitive email.
