Macy is a personal AI agent that operates inside Apple's iMessage, connecting to over 500 external apps to proactively monitor your digital life and initiate conversations via text messages.
What is Macy?
Macy is a personal AI assistant that lives as a contact in your iMessage app. It connects to your Gmail, Google Calendar, Google Drive, Slack, WhatsApp, Robinhood, and 500+ other services through a web dashboard. Macy watches your inbox, calendar, markets, and group chats around the clock and texts you first when something requires attention—like a flight change, price alert, or a decision in a group chat. It is built by the team at heymacy.ai.
Key Features
- Proactive notifications – Macy sends you a text message before you think to check—e.g., flight delays, price alerts, important emails—without requiring you to open any app.
- 500+ app integrations – Connect Gmail, Calendar, Drive, Slack, WhatsApp, Robinhood, Notion, and more from the web dashboard; all interactions happen in the iMessage thread.
- Document memory – Save files, notes, and documents to a private drive; retrieve them on demand with a single text (e.g., "get the lease I saved on March 9").
- Automated trading – Macy researches and proposes trades via Robinhood's agent API; nothing executes until you reply "yes" in iMessage.
- Cross-app chains – A single "yes" can trigger multiple actions: catch an email, save the file to Drive, and draft a WhatsApp reply—all from one thread.
- Standing rules – Set a condition once (e.g., "trim NVDA if it drops 5%") and Macy monitors continuously, only proposing the move when it triggers.
- In-chat content generation – Ask for a sticker, an image, or a short video; Macy generates it directly in the chat for sharing.
- Language learning – Macy texts you daily Spanish lessons, sends audio, and corrects voice notes you send back—no separate app required.
- Memory of preferences – Tell Macy you like the window seat once; it remembers your preferences and uses them in future recommendations.
Who is it for?
- Busy professionals – who want a chief-of-staff that watches their calendar, email, and notifications, and proactively handles schedule changes and reminders via text.
- Active investors – who want to set trading rules and get notified of opportunities, but require explicit approval before any trade executes.
- Multitaskers with group chats – who need summaries of family or work chats, urgent messages surfaced, and replies sent on their behalf through WhatsApp or email.
- Language learners – who want daily practice with audio and correction sent directly to iMessage without maintaining a separate app habit.
Use cases
- Flight change management – Macy detects a schedule change in your email, texts you the new time, and offers to reschedule a dinner appointment—all confirmed with a single "yes."
- Group chat summarization – In a busy family WhatsApp group, Macy summarizes the flood, flags decisions, and lets you reply without scrolling through hundreds of messages.
- Document retrieval – Ask "where's that lease from March?" and Macy fetches the exact file you saved earlier from the private drive.
- Trading with guardrails – Set a rule like "sell if NVDA hits $150"; Macy watches the market and texts you a proposal; nothing happens until you approve.
