Why people who live in their inbox stay.

Workspaces

Work, the side project, the family thread. Each account sealed in its own space, with its own signature and its own silence.

Plain text, on purpose

Writes plain text by default and renders it the same way. No tracking pixels, no marketing HTML, no read receipts.

Real threads

Back and forth stays in one place and in order, the way the conversation actually happened.

Nothing else

No AI summaries, no CRM, no snooze-and-boomerang. It is an inbox, and it intends to stay one.

Like Charlie? You might love Viola.

Viola is our web browser: the same restraint and the same quiet defaults, pointed at your tabs instead of your inbox.

Frequent questions

Everything worth knowing before you point your mail at Charlie.

What makes Charlie different?

Workspaces, and threads that read like conversations instead of stacks of quoted replies. Beyond that, deliberately very little.

Why does it do so little?

Because an inbox that also wants to be a calendar, a task list and an assistant is four things done adequately. Charlie is one thing.

Does Charlie use AI?

No. No summaries, no smart replies, no drafting. Your mail is not training data and nothing is sent anywhere to be interpreted.

Where does my mail live?

On your device. Charlie talks to your mail provider directly and keeps its cache locally.

Is this related to Viola?

Same people, same design language, same restraint. Charlie is the inbox, Viola is the browser.
