Process

Three steps. Five minutes.

From mailbox connection to one-tap WhatsApp replies in under five minutes.

01

Connect your mailbox in 60 seconds

One-click sign-in via your existing Azure AD. We don't see your password. We don't store your emails. Your organisation's MFA, conditional access, and DLP policies apply automatically — because we use Microsoft Graph, not a copy of your inbox.

02

AI reads, prioritises, drafts

Every minute, the assistant scans new mail. It reads the full thread — not just the latest message. It classifies priority and tells you why. It drafts a reply in your tone, in the language and register of the inbound email. Drafts land in your Outlook ready to review.

03

Act from WhatsApp

High-priority emails arrive on WhatsApp with a summary, the reasoning behind the flag, and a suggested reply. Type SEND, SKIP, or CHANGE to act in seconds — no inbox, no laptop, no app switch.

What makes BJ Assistant different

Four things no other inbox AI does this way.

The features US-built rivals miss when they default to monolingual English and untraceable AI guesses.

// 01 · Language

Drafts in your reader's language. And register.

German Sie. German du. British English. American English. French formel. Detected automatically from the inbound email — overridable per contact.

DESehr geehrter Herr Mustermann → Sie-Form DEHi Markus → du-Form ENMirrors UK or US spelling and idiom
// 02 · Trust

Every priority comes with reasoning.

The assistant doesn't just flag — it explains. "Flagged because sender is in your top-10 contacts and the email mentions a deadline this week." Disagree? Override it once and it remembers.

HIGHWhy: deadline mentioned + reply-required to a frequent correspondent
// 03 · Away mode

Smarter than an Outlook auto-reply.

Tell the assistant you're at LogiMAT until Thursday. It writes contextual holding replies in your voice. Genuinely urgent emails still escape to WhatsApp — flagged as "during away mode."

OOOAuto-acknowledged in your voice, with your context URGENTStill escapes to WhatsApp, tagged "during away mode"
// 04 · Meeting prep

A briefing before every meeting.

An email arrives ahead of each meeting: who you're meeting, the agenda, the relevant figures and open threads pulled from your inbox, plus location or dial-in. The kind of thing an executive assistant gives you. Now you have one.

Plus the basics, done right

The table stakes — finally delivered properly.

// 05 · Context

Reads the thread, not just the message.

Drafts that reference earlier commitments and don't repeat already-answered questions.

// 06 · Mobile

One-word replies from WhatsApp.

SEND, SKIP, or CHANGE. No app to install. No inbox to open.

// 07 · Sync

Microsoft To Do, synced both ways.

Todos flow into your default list automatically. Edits and completions stay in sync.

// 08 · Focus

Focus time and lunch, booked for you.

Tell the assistant how much focus time you want. It books focus blocks and a daily lunch break straight into your calendar — up to four weeks ahead, refreshed weekly, without double-booking or clumping.

// 09 · Security

Your data, your tenant. Always.

Each company connects their own Azure AD app. We never see your password. We never store your emails. EU-hosted infrastructure throughout.

// 10 · Threads

30 days of mail, organised by conversation.

Every message from the last month — sent and received — grouped into threads. Open one and read it top-to-bottom, your replies inline.

// 11 · Briefings

Summarise any thread in one click.

Long back-and-forth? Hit Summarise. The assistant returns where things stand, what you still need to do, and the overall priority. Works in Inbox, Last 30 days, and Archive.

// 12 · Knowledge

Ask your mailbox a question.

"What did Anna decide about the Q3 budget?" Knowledge AI searches your emails and answers with sources. Locked to your inbox — not a free-form chatbot.

// 13 · Daily brief

Your day, in one morning email.

A daily brief lands in your inbox: today's meetings, what's urgent, and what still needs a reply — generated fresh each morning.

// 14 · Travel

Flights and hotels, on your calendar automatically.

Booking confirmations become calendar entries with airport travel time blocked — and flight delays are tracked live, so you know before you leave.

// 15 · Follow-ups

Follow-ups that don't slip.

When an offer or proposal you sent goes quiet, the assistant drafts a nudge and adds a to-do — so nothing falls through the cracks.

// data_handling.md

Your data, your tenant. Always.

We don't store your emails. Anywhere. Ever.

Email content stays in your Microsoft 365 mailbox. When the assistant drafts a reply, the message is processed in-memory in EU infrastructure, and the draft is written straight back to your Outlook. We keep no copy.

The only persistent trace is a short-lived deduplication marker — purged after 30 days — so the assistant doesn't process the same email twice.

Voice notes from WhatsApp are transcribed in-memory and discarded. We don't retain audio.

No US data residency. No third-party model providers outside the EU. No exceptions.

FAQ

Six questions, no fluff.

Does it work with Gmail?

No. BJ Assistant is Microsoft 365 only — and that's deliberate. We focus on doing M365 right, not on covering every email provider.

Where is my data processed?

EU infrastructure throughout. No US data residency. No third-party model providers outside the EU.

Can I use it in German?

Yes — and in the right register. The assistant detects whether the inbound email is Sie or du form and drafts accordingly. French and Italian supported as v1.5.

Does it auto-send emails?

Never. Every reply is a draft until you approve it — in Outlook, or with one word over WhatsApp.

How is this different from Microsoft Copilot?

Copilot drafts inside Outlook. BJ Assistant works outside Outlook — over WhatsApp, with priority reasoning, multilingual register detection, and meeting briefings. Use both, if you like.

What if I'm at a conference for a week?

Tell the assistant you're away. It sends contextual holding replies in your voice. Genuinely urgent emails still escape to WhatsApp — flagged so you know.
