A job in plain words

The Ask bar is the same everywhere: Today, Agent, ⌘K, the phone. It acknowledges in one line before any tool runs.

The part no personal agent has

They know your inbox. Sentra knows your company.

Hi Will, quick note on the V3 date. Engineering moved the target to October 20 when the telemetry rework was scoped; the campaign is still October 6. I'm locking one date this week and will confirm by Thursday.

FAQ

Only what you connect and tick: your calendar, your mail, the channels you are in, the docs shared with you. Never other people's DMs. You can untick anything, and the trace shows you exactly what it read.

No. Reading and drafting happen on their own; sending, booking, posting and buying wait for your word, every time. There is no approve-all.

They know your inbox. Sentra knows your company: every decision, promise and change across the meetings, threads and docs you can see, with a receipt on each. And it is built to be allowed at work: guardrails, an activity log, nothing sent without you.

In Sentra's own environment, encrypted, never used to train models. Your personal pages are yours alone. When your team turns on the organization memory, you share only what you already have access to at work.

When three people at one domain have a personal Sentra, each sees a card to turn on the organization memory. One click, thirty days free. Your personal pages stay personal.

Disconnect any source in one click. Ask it to forget a person, a source or everything. Deletion within 30 days, confirmed in your activity log.

The best contact in your phone, and the only one your company trusts.
