Macchiato is a chat app built from the ground up for talking to your AI agent — not to other people. Personal agents today borrow human messaging apps like Telegram or Discord. But those apps were designed for people talking to people, so an agent's real work — tool calls, file edits, approvals, progress — gets flattened into a wall of text. Macchiato is different: every part of the interface is designed around the way an agent actually works. PAIR YOUR OWN AGENT Scan a QR code to securely link the agent running on your own machine. Macchiato is the front end; your agent stays where you run it. Add more than one and switch between them in a tap. SEE STRUCTURE, NOT A WALL OF TEXT • Tool calls render as clean cards instead of raw logs • File changes show up as readable diffs • Approvals become real buttons you tap to allow or deny — and the history shows exactly what you approved • Replies stream in token-by-token, and you can interrupt any time SAY SOMETHING MID-TASK • Send it straight into the running task — no interruption • Or queue it: it waits in the chat, greyed out, and one tap takes it back • Or stop and take over • Background tasks and pending approvals dock above the composer, always in reach TALK, TYPE, OR SEND FILES • Tap to record a voice message and your agent transcribes it • Attach images, PDFs, and documents • Rich Markdown, code blocks, and tables, rendered natively with selectable text STAY ORGANIZED • Keep many conversations going at once and jump between them instantly • Full-text search across your whole history • Pin, rename, and archive conversations PRIVACY BY DESIGN • Passwordless email sign-in — no password to leak • Optional per-conversation end-to-end encryption: your device and your own agent hold the keys, and our servers only relay the ciphertext • We never sell your messages, use them to target ads, or train models on them Built as a fully native iOS app — system typography, materials, haptics, and automatic light and dark themes — so it feels at home on your iPhone. Note: Macchiato is the client for an AI agent that you run yourself — Hermes, OpenClaw, Claude Code, or Codex. You pair your agent once by scanning a QR code; the app talks to it through our relay.
