Email you already know, far more powerful with AI.
The unread pile. The reply you keep postponing. The filters you never got working. Conduit handles them with you — familiar on the surface, doing things underneath that email apps haven't done before.
Web · installable PWA · desktop and mobile apps on the way — works with Gmail, Yahoo, AOL, iCloud, Fastmail, IMAP
You loved email once. You can again.
There's a reply you've drafted four times in your head. It still hasn't left today.
Drafted below ↓Filters would help. You've known that for years. The dialog box stands in the way.
Rewritten below ↓The AI mail apps are impressive. Step one: ship them your whole mailbox, they say.
Answered below ↓Not a haiku, not quite a sonnet — though we're partial to the lineage.
One keystroke. The whole inbox.
A command palette that answers back. Ask it to find the thread from last Tuesday, summarize it, draft the reply, label it, file it. It has real tools on your mail, and it shows every action it takes in an activity strip while it works.
- Searches your mail, summarizes threads, drafts and sends replies
- Applies labels, writes automation rules, saves notes
- Shows its work, action by action, as it goes
Draft in your voice, not the model's.
Describe what you want to say and get a draft that reads like you wrote it — Conduit learns your voice from writing samples it collects from your sent mail. Then rewrite a paragraph, fix the grammar, or move the tone up or down without leaving the composer.
- Describe it, get a draft
- Rewrite, grammar and tone, in place
- Undo send with a delay you set, for the ones you regret
Your inbox, already sorted.
Every message that arrives is read for what it is and filed into one of six categories. The pile becomes six short lists, and the list you actually care about sits at the top. Conduit gets a call wrong now and then, and you can move it.
One morning of mail, sorted on arrival.
Describe a rule. Conduit builds it.
Type archive receipts older than a month and label them Receipts. What you get back is a real rule, laid out where you can read every condition, edit it, or switch it off.
Search like you'd ask a coworker.
Ask for invoices from Stripe over $50 this year. Conduit turns the sentence into structured filters and shows them as chips you can adjust or throw away. No operators, no colons, no quote marks in the wrong place.
The sentence is interpreted by Claude; the filters then run against mail already on your device.
The sentence becomes a chip you can edit.
Your AI can finally see your email.
Conduit runs a hosted MCP server. Connect claude.ai, Claude Desktop, or Claude Code to your mailbox and Claude can read, search, draft, and manage your mail — with the permissions you grant, one capability at a time, revocable whenever you want.
No mainstream email client has this. It is the feature we are proudest of, and the one that takes the longest to explain at parties.
Your inbox lives on your devices, not in our database.
Mail passes through our servers on its way to you; it isn't stored there. Our database has no table for your email.
Nothing indexed on our servers
The sentence you type is interpreted by Claude and turned into filter chips. The filters then run against mail already on your device — nothing is indexed on our servers.
Never training data
Your email is never used to train AI models. Not by us, not by Anthropic — their commercial API terms forbid it, and Google's restricted-scope rules bind us to it in writing.
AI waits to be asked
AI features are yours to invoke — summaries, drafts, search, and chat all wait for you to ask. One thing runs on its own: sorting new mail into six categories. A local classifier on your device does the sorting. On paid plans, the messages it's unsure about get a second look — just the sender, subject, and a short preview go to Anthropic, never the body. On the free plan, categorization stays entirely on your device and sends nothing.
We don't store your emails. We do store a few small things that make Conduit work the same on every device — your rules, the notes you save, and short writing samples from your sent mail so drafts sound like you everywhere. All of it is visible in Settings, and all of it is yours to turn off or delete.
