Hilo — Mail for Mac that reads like a conversation

Mail that reads like a conversation.

Hilo folds long threads, hides the quoted history, and turns any conversation into chat bubbles when that's easier to follow. Fast, native, and private.

Every thread, two ways to read it. Switch with one click.

Built for long threads

Never lose your place in a 40-message thread again.

Most mail apps stack every reply on top of the last one, quotes and all. Hilo shows you what's new and gets everything else out of the way.

Folded history

Older messages collapse into one line. Read ones shrink to a summary; unread ones stay open.

Classic or bubbles

Read like email or like a chat. Pick a default, then switch any thread with one click.

Private by design

Your mail is cached only on your Mac. Hilo talks directly to Google — no Hilo servers in between.

Works with Claude

A built-in MCP server lets Claude search, summarize and draft replies. It can't send — that stays with you.

Your data

What Hilo does with your Gmail.

Hilo asks Google for permission to read and organize your mail so it can show it to you. That's all it uses it for.

Mail is stored only on your Mac, in Hilo's local database.
Sign-in tokens live in the macOS Keychain.
No analytics, no ads, no selling or sharing of your data.
Disconnect any time from Hilo or your Google account settings.
