An inbox that moves life forward
Bring Gmail, Outlook, and Fastmail together, then turn a message into action while the reason, people, and conversation are still attached.

More life. Less upkeep.
Everything around the work, finally working together
Meridian keeps the connective work organized — the conversation, the commitment, and the time to do it — so you can stop carrying your whole day in your head.
A schedule that feels intentional
See every calendar together and make room for the work that matters, instead of letting the next meeting decide your whole day.
To-dos you can actually finish
Keep the source conversation close, break work into clear next steps, and give important tasks real space around the life already on your calendar.
A second brain that stays yours
Catch action items, understand long threads, draft the first reply, and find what you meant — with intelligence that runs on your Mac.
Let the busywork fade into the background
From scattered inputs to a day you can trust
The message becomes the task. The task finds its place in the day. The context stays attached all the way to done — without another system to babysit.
Bring your world together
Add Google, Microsoft 365, Fastmail, or iCloud and see the full shape of your day without bouncing between accounts.
Turn intention into a plan
Drag a message into To-Dos & Reminders to create the work, or attach it to an activity already moving forward.
Move through the day with clarity
Know what needs a reply, what is due, and what comes next — then focus without wondering what you forgot.
Nothing important, forgotten
Stop relying on memory to keep every promise
Meridian notices the replies, commitments, conflicts, and overdue work that are easy to miss, then brings each one back when you can do something about it.
Explore on-device AIPrivate enough for real life
An assistant only works if you can trust it
Your inbox and calendar contain the story of your life. Meridian is built to help with that story without reading it in the cloud: provider connections and AI run on your Mac, and synced content is encrypted before it leaves.
Read about securityOn-device provider access
Your Mac talks directly to Google, Microsoft, Fastmail, and iCloud for provider sync and write-back.
Local AI
Language models and semantic search run locally. Your content is not sent to a cloud AI service or used to train one.
End-to-end encrypted sync
Synced content and portable provider credentials are encrypted client-side so Meridian's servers cannot read them.
Ready when you are
Get your time back — and spend it like it matters
Make space for focused work, present conversations, and evenings that do not begin with wondering what you forgot.
