EP365 Private secure AI a private AI assistant inside your Microsoft 365
A full-featured AI for every employee — right inside your Microsoft 365. It answers from your company documents (with a link to the source), and handles your everyday work too: mail, calendar and tasks. One licence for the whole team, your data stays with you.
Ask in plain language – about a contract, an email to a client or a revenue overview. The assistant answers right inside your SharePoint, and your data stays in your Microsoft 365. Click the demo to enlarge it.
Sound familiar?
This is what companies tell us before they deploy secure AI. Not because people are doing anything wrong — they simply want to work faster and reach for whatever is to hand. But personal ChatGPT was never built for company data.
“Half the office is quietly pasting work into ChatGPT.”
They write emails there, translate contracts, summarise meeting notes. Company data leaves the organisation and nobody knows where it goes — until something goes wrong.
“We do have AI, but five enthusiasts use it.”
The rest of the company is left out. Copilot is excellent, but it's licensed per head — so in the end only a chosen few get it.
“Who is allowed to use AI, for what, and with which data?”
There are no rules and no overview. Without control over where data flows, the security team simply won't let new tools through.
What Private AI does about it
The assistant isn't just about documents — it also helps with mail, calendar and tasks, and everything stays with you. The complete feature list is below in the details.
Answers from your documents — with a link to the source
Flip a toggle next to your question and within seconds the assistant searches your documents across SharePoint and Teams. It answers and shows which documents it drew on — click to open the source straight away. It can also summarise several documents at once, or compare two versions and tell you what changed. On top of that, you can turn an answer or your company knowledge straight into new content — a Word document, a SharePoint page, or a social media post.

Not just documents — mail, calendar and tasks
The assistant handles your everyday work over your mailbox and calendar too: in the morning it assembles a brief (meetings, mail to reply to, tasks), drafts a reply as an Outlook draft, triages your mail or turns a meeting into minutes, and pushes tasks into Microsoft To Do. It never sends or deletes anything — you just confirm.
Switching between Outlook, calendar and tasks the assistant prepares it, you confirm
Your data stays with you in Microsoft 365
Conversations, attachments and settings are stored exclusively in your Microsoft 365. The AI model runs in your Azure subscription and, in the default deployment, processes requests only in European datacentres — your content stays in your Microsoft environment and is not trained on. No third-party cloud.
Everyone sees only what they're entitled to
The assistant searches under the identity of whoever is asking. So two colleagues can get different answers to the same question — depending on what each of them is allowed to see.
Shared prompts for the whole team
Prepare proven templates for emails, summaries or translations once and share them across the company. Everyone starts from a solid brief, not a blank field.
The fastest route: 30 minutes at a screen.
No company slideshow. We share a screen and click through the assistant on sample data — you'll see exactly what your people would see, including answers from documents with a link to the source.
„People wanted AI. Now they finally have it — and we don't lose sleep over where the data goes. In the first month 78% of people moved to the company assistant.“
Manufacturing company · 240 employees
Deployment took five days from the kick-off call. Beforehand, IT found that over 60 people were using personal ChatGPT accounts for company tasks — now everything is under one roof.
For those who want to know more
Everything that matters in one place — features, a comparison with Copilot and ChatGPT, security, pricing and answers to the common questions from CIOs and security teams.
Chat right inside your environment
The assistant is part of your company page in Microsoft 365. Answers stream as they're written, you save conversations with favourites, tags and an archive, search within them and export to Word, Excel or HTML. On request it drafts an email, a task or a calendar event too. No installation, no extra sign-ins — in English and Czech.
Answers from your documents
Flip a toggle next to your question and the assistant searches your documents across SharePoint and Teams. It answers with a link to the source (a click opens a preview), summarises material from several documents at once and compares their versions. You can also ask about people from the company directory (“who handles health and safety here?”) or by time (“what's new in the policies over the last month”).
Verified (authoritative) sources
An administrator marks key areas of content — policies, regulations, official procedures — as verified sources. The assistant draws on them first, visibly flags them in the answer, and when a regular document contradicts a valid policy it points out the discrepancy and follows the verified version. A verified source can optionally be limited to members of a specific Entra ID group (e.g. the sales playbook only for the sales team) — SharePoint permissions always apply.
Attachments: PDF, Word, Excel, images
Attach a file from your computer or pick one straight from the company library. The assistant reads text from PDF, Word, Excel and PowerPoint, and understands images too. Attachment content is never stored — only the file name.
Prompt Studio — all your prompts in one place
One place where everyone has every assistant prompt at hand — open it with a button or by typing “/”. It opens with an overview of scenarios (Mail, Calendar, Teams, SharePoint, Writing & summaries, Analysis, Translation & language, Code, Excel, Social media) — pick a scenario and its tasks and assistants sit together. In two layers: Tasks are ready-made briefs that drop into your message (summarise a document, write an email, translate, find the right person), while Assistants are specialised personas that set the behaviour of the whole conversation (legal adviser, HR guide, translator). You pick from a ready-made gallery, centrally managed company-shared prompts, or your own personal ones. On top of that, you smartly add real company documents, people and conversations right into the brief.
Mail, calendar and tasks
The assistant handles your everyday work too — always over your own mailbox and calendar, and under your own sign-in. In the morning it assembles a “Prepare me for tomorrow” brief (meetings, mail awaiting a reply and tasks from Microsoft To Do), drafts a reply to an email, triages your mail into groups with bulk actions (categories, archiving) and turns a meeting into minutes with an email to attendees. The key part: it never sends or deletes anything — replies and emails are created as Outlook drafts, tasks go into Microsoft To Do in one click, and the final step is always yours. An administrator enables the area (a one-time consent to Microsoft permissions) and can switch it off for the organisation.
Document creation
From a conversation or from company knowledge, have the assistant write a document — a summary and conclusions, a piece on a topic (with clickable source links), a comparison of documents, or the content of a new web page. You see a formatted preview and can edit it before saving. Download it as Word (.docx), Markdown or HTML, save it to a chosen SharePoint library, or turn it straight into a SharePoint page — all under your sign-in and only over your data. Prompt Studio has ready tasks for it (Summarize into a document, Document from SharePoint sources, Compare, Web page).
Social media content
From company knowledge or a conversation, the assistant writes a social media post (for LinkedIn, say) — you edit the draft and save it as Markdown (.md) to a chosen SharePoint library. Because it then knows the saved posts, you can come back and ask “what did we last post about…”, have it follow up on an earlier post, or request an overview of what you've published. Prompt Studio has a dedicated Social media scenario for it (write a post, follow up, overview).
Floating assistant on every page
The assistant doesn't wait on a single page — a floating button opens it anywhere on the site, including answers from your documents. In one click you move the conversation into the full application, along with its attachments and templates.
Daily limits and privacy
Every user has a daily query limit you set. Conversations are private — nobody ever sees anyone else's, by any route. For oversight you can optionally enable administrator supervision and a record of searches; both are off by default and people always know about them.
Cost overview for administrators
A monthly overview: total queries, consumption, estimated cost, a daily chart, the top 10 most active people and the engagement rate (daily / weekly / monthly). Costs in black and white.
What's new and feedback inside the app
The What's new page shows what each version added, improved and fixed, with the version you run highlighted. People can report a bug or suggest a feature straight from the application.
Central management across sites
With Workplace deployed, you manage the assistant's key settings from one place for all sites: company prompts, answer sources and the AI's default behaviour. Each site either inherits the values or configures its own.
Data stays with you
Conversations, messages and settings are stored exclusively in your Microsoft 365. No data travels to our servers or to a third-party cloud.
Everyone sees only their own
By default each employee sees only their own conversations. Other people's data is technically out of reach, even if someone knew the direct link.
SharePoint guards permissions
Answers from documents draw only on content the person has access to. The application has no privileged account that could see more than the person asking.
No copy of your data
Document search happens at the moment of the query, directly over your SharePoint. No external index or copy of the files is created — the administrator sets the scope.
Controlled oversight — optional
For oversight purposes you can enable administrator supervision of conversations (§316 of the Czech Labour Code) and a record of searches. Both are off by default, and the user always sees whether their conversations are private or visible to an administrator.
Access keys kept hidden
The AI model's keys are held securely on the server side. They never reach the browser — neither users nor anyone on the site can see them.
AI that doesn't learn from your data
Microsoft contractually guarantees your content is not used to train models — unlike consumer AI tools.
Outside company search
Conversations with the assistant never appear in SharePoint search results — they're completely excluded from it.
Hosted in the EU
The AI service and the model run in European Azure regions (Sweden Central by default) and the model is deployed as Data Zone EU — requests are processed only in European datacentres (EU Data Boundary).
Roll AI out to the whole company. Pay only for what it actually does.
The price follows the number of AI actions per month. An AI action is one completed assistant response to a person's request — a chat answer, an email draft, meeting minutes, a filled-in template. Not every click counts: internal intermediate steps, failed attempts and background document preparation are never counted as actions. No per-seat licence maths — everyone in the company can use the assistant. Your band is set by the average of the last three months (it works in both directions), and the start is risk-free: measurement comes first, so you know your real volume before you pay. Administrators see how many actions your company makes day by day in the app — the same numbers we bill from. Running the AI model itself comes straight from your Azure subscription (typically ~CZK 0.10–0.40 per action).
On-site implementation
We take care of getting you started: installation, configuration, connecting your AI model and training your people. Starter (one site / one department) usually takes 3–5 days, a full company rollout 5–10 working days.
The exact price depends on the size of the organisation, the scope of the rollout and any regulatory requirements. We'll send a precise quote after a short call.
Support pricing
Consultations, environment adjustments, model tuning or user support.
Support is billed per started 15 minutes of work. We always tell you the expected scope in advance.
A worked example: company of 60, first six months
The start is measurement only — the first month is free. Then you are invoiced in advance by the band from the average of recent months. Growth moves you up smoothly, and down the same way when usage drops.

What is an AI action?
One completed assistant response to a person's request — a chat answer, an email draft, meeting minutes, a filled-in template. Not every click counts: internal intermediate steps, failed attempts and background document preparation are never counted. Administrators see the same numbers we bill from, day by day, right in the app.
What will AI cost you per month?
Two separate items: the EP365 band you pay us, and the model tokens you pay Microsoft directly from your own Azure. Change anything — the estimate recalculates instantly.
Typically 20–40 % of employees use AI regularly.
A regular user makes ~4 actions a working day (Worklytics 2025, OpenAI/NBER).
The app sends a different amount of text to the model depending on the task — an attached document and a company-knowledge question cost more than a plain question. Set the mix and the token consumption recalculates.
system prompt plus conversation history (default depth 10 messages)
an extra 15,000 characters of document text (the default per-file cap)
snippets from found documents fill the message budget up to the 32,000-character cap
The most expensive action has a ceiling: the administrator sets the message budget (32,000 characters by default), and the input never exceeds it.
Advanced assumptions
Defaults describe a typical question over company knowledge: system prompt, conversation history and retrieved document excerpts on the input, a paragraph answer with citations on the output.
