Native to Gmail

One place for all
your Google accounts.

Apple Mail can fetch your Gmail, but it flattens it into generic IMAP folders and one grey pile. Clementine talks straight to the Gmail API, so every account keeps its labels, categories, and its own color.

In Apple Mail
  • Gmail labels collapse into plain folders
  • Every account piles into one grey inbox
  • IMAP search, no Primary / Social categories
In Clementine
  • Real labels and categories, exactly like Gmail
  • A signature color for every account space
  • Gmail-native search, archive, and shortcuts

Spaces with their own color.

Give each account a signature color and the whole window dresses to match, so you always know which hat you're wearing before you hit send.

  • Unified inbox, or one space per account.
  • Per-profile colors, notifications & Focus filters.
  • Categories & labels, exactly like Gmail, only faster.
Gmail, all of it

Real Gmail,
kept intact.

Categories, labels, filters, snooze, the whole Gmail feature set a generic mail app loses, working natively on your Mac.

  • Inbox Categories

    Primary, Social, Promotions and Updates, sorted by Gmail so your inbox shows only what matters.

  • Gmail Labels

    Full Gmail labels with color-coding and visibility, kept as labels and never flattened into folders.

  • Filters

    Create and manage your server-side Gmail filters without leaving the app.

  • Snooze

    Snooze a thread out of the inbox and have it return at a better time.

  • List Filtering

    Narrow the list to unread, starred, or whatever you need, in a tap.

  • Vacation Responder

    Set up and manage your Gmail vacation reply right from your Mac.

Calm AI

Help that waits
to be asked.

No autopilot, no pop-ups, nothing humming in the background. It waits until you ask, then summarizes the thread or writes the draft.

The gist, in one tap.

Eleven replies deep? One click turns the whole thread into a paragraph that says exactly what's being asked of you, and a "Needs you" lane surfaces the mail that actually wants a reply.

  • Summaries read the full thread, not just the last note.
  • Nothing runs in the background, only when you click.

Fast and effortless writing.

Formatting, mentions, and signatures sit where your fingers expect them. Tell the AI what to say and it drafts a full reply in your voice, then hands it back. It never sends on its own.

  • Rich text, @-mentions, templates, and send-later, built in.
  • AI rewrites, shortens, or fixes the tone, in your voice.
  • You're always the last set of eyes before it sends.
Bring your own model
OpenAIAnthropicGoogle GeminiMistralLocal models

Connect your own API key and Clementine uses it as-is. No markup on usage, no lock-in, and your mail is never sent off to train anyone's model.

For builders & agents

Give your agent
an inbox.

Clementine already holds your authenticated Google connection, so the clem CLI works the second you install it. No server to run, no OAuth to wire, no infrastructure to babysit. Triage, search, summarize, and send, straight from your terminal or an agent.

Your inbox, as an API.

Pipe messages into any model, wire it into an MCP server, or let an agent clear your low-priority mail overnight. Local-first, permissioned, and auditable: it only does what you allow.

  • $ clem inbox --needs-reply --json
  • $ clem summarize thread_8f2 --space work
  • $ clem draft --to jordan --voice "confirm the rate"
  • $ clem mcp serve
◇ Works with the Model Context Protocol
Built for privacy

Your email is
your business.

Clementine keeps your data and your tokens on your device, and connects straight to the Gmail API. No intermediary sync service ever touches your mail.
