Light Speed
A native macOS Gmail client that opens, archives, and replies before browser-based alternatives finish loading the page.
Free 7-day trial. No credit card required. macOS 14+
Inbox zero by 9:15am
Your inbox is already sorted when you arrive. Cold pitches are filtered. Newsletters are in their own lane. You start with the emails that actually matter.
Your inbox organizes itself
An on-device ML model classifies every email the instant it arrives into Priority, Team, Newsletters, Transactions, Calendar, and Updates. Cold sales pitches are auto-detected and routed out of your way. No rules to write. No filters to maintain.
Classification runs on your Mac first
The classifier runs locally on your Mac's Neural Engine. When it's confident, nothing leaves your device. Low-confidence emails are sent to an LLM for a second opinion — no subject lines, no sender names, just the signals needed to classify. Your corrections improve the model for everyone through differential privacy.
Premium value, half the price
Premium email clients charge $25/month or gate their best features behind higher tiers. Hyperdrive is $13/month with everything included. One plan, every feature, no tiers. 7-day free trial, no credit card.
Everything you need to own your inbox, nothing you don't
Every feature exists because we built the email client we couldn't find anywhere else.
Keyboard-native, not keyboard-optional
100+ shortcuts. Vim-style chords (g+i for inbox, g+e for done). A command palette (Cmd+K) that searches actions, contacts, threads, and settings. Rebind any key. Navigate your entire inbox without lifting your hands.
Sales pitches, gone before you see them
On-device ML scores every inbound email for cold-pitch signals — opt-out links, "quick call" language, founder intros from strangers. Pitches are quietly routed to a separate vector. No rules to write. Adjust sensitivity or rescue false positives with one click.
Scheduling links and a full calendar
Share your availability as a booking link. Recipients pick a time and the event auto-creates. Day, week, and month views in a sidebar. Create events from email threads. RSVP to invites without opening Google Calendar. Zoom and Google Meet integration.
Messages and email in one inbox
Connect your Slack workspace and read DMs, channels, and mentions alongside your email. Reply from the same keyboard. One triage flow, zero tab switching. Read/unread state syncs across devices.
Know when your email gets read
Pixel-free read tracking shows who opened your message and when. Contact cards surface job title, company, social links, and your full conversation history. Know who you're talking to before you reply.
Snooze, send later, reminders
Type "next Tuesday 9am" and the email vanishes until then. Schedule sends with Cmd+Shift+Enter. Set reminders on threads you're waiting on. Natural language parsing. No date pickers, no dropdowns. Cross-device sync.
Native macOS. Not a browser in disguise.
Hyperdrive is built with AppKit and Swift, the same frameworks Apple uses for Mail.app. No Electron. No web wrapper. No Chrome process eating your RAM.
How Hyperdrive compares
Local-first instead of server-round-trip
Gmail's web UI fetches every thread over the network. Hyperdrive stores your inbox locally — search returns results as you type, navigation doesn't wait on a server, and you can triage offline. Adds keyboard shortcuts, vector sorting, and a denser UI.
Same speed, more features, lower price
Hyperdrive includes Slack integration, a full calendar with scheduling links, on-device ML classification, cold pitch filtering, and Zoom/Meet integration. $13/month vs $25/month.
Built for individual power users
Spark focuses on team collaboration features. Hyperdrive is built for individuals who process high volumes of email solo. One price, every feature, and your email stays on your Mac.
Try it for 7 days. You won't go back.
