Which AI runs natively in Microsoft Teams?

Introduction

The question “Which AI runs directly inside Microsoft Teams?” has a clear answer: Microsoft 365 Copilot, Teams Premium and amaiko are the three most important AI solutions that are natively integrated into Microsoft Teams and work without separate applications. The decisive difference, however, is not mere availability — it is depth of integration and the ability to build persistent corporate knowledge.

Native AI features differ fundamentally from add-on tools: they run directly inside the Microsoft 365 infrastructure, require no separate user accounts and tap into existing data structures in Teams, SharePoint and Outlook. Add-on tools, by contrast, demand external platforms, additional logins, and frequently cause context switches in day-to-day work.

This article is aimed at mid-market B2B companies with an existing M365 infrastructure that want to deploy AI tools deliberately without launching months-long IT projects. The focus is on choosing the best AI solutions for different business needs, taking into account both company requirements and end-user concerns — particularly usability and per-user cost.

The core problem: the fragmented tool landscape in many companies prevents AI from being seamlessly integrated into existing workflows. The answer lies in native AI knowledge layers that replace multiple tools like amaiko, draping themselves over the existing infrastructure.

The most important takeaways from this article:

• Session-based AI solutions forget the context after every session; persistent systems like amaiko continuously build up corporate knowledge
• The integration depth of AI tools into Microsoft Teams determines how seamlessly they slot into existing workflows
• GDPR-compliant AI solutions with German hosting eliminate compliance risks without a configuration marathon
• Automatic knowledge build-up from real interactions replaces manual wiki upkeep
• AI supports the organizational analysis of meetings in real time and creates personalized summaries

The problem with AI gadgets: why “plug & play” so often breaks against IT reality

Many AI tools are marketed as quick fixes but founder on the IT reality of the mid-market. Separate AI applications fuel shadow IT: employees use tools that have not been approved by IT and store sensitive corporate data on external servers. Transparency in AI data processing is often missing entirely. Nobody knows what data flows where. On top of that, the missing or limited features of these external tools complicate everyday work, because central capabilities such as automated meeting management or privacy controls are not integrated.

US-based tools without GDPR-compliant hosting pose a significant risk. Data minimization is one of the central principles of GDPR (Art. 5): only the personal data that is strictly necessary for the processing purpose may be processed. Many external AI tools fail to meet this requirement and transfer more data than necessary. Securely managing and controlling this data also requires specialist technical know-how to deliver data protection, AI governance and compliance reliably.

The IT overhead caused by fragmented tool stacks is measurable: additional user accounts, separate permission management, divergent privacy standards and a lack of conformity with existing compliance policies. Internal support is missing too, because fragmented AI tools offer no central support for IT helpdesk, HR policies or access to employee knowledge. IT administrators spend valuable time managing tools that were supposed to deliver efficiency.

Classic wikis and knowledge-management systems fail at manual data upkeep. Knowledge ages, documents are not updated, and new employees can’t find relevant information. Usage drops until they are eventually abandoned.

Why separate AI tools undermine M365 efficiency

Context switches between Teams, SharePoint, Outlook and external AI applications cost time every day. A typical scenario: you receive an email in Outlook, have to search for relevant files in SharePoint, reconstruct the context from a Teams chat and then craft a summary in a separate AI tool. Every context switch breaks your workflow and reduces productivity.

The lost time adds up. Employees spend several hours a week looking for information across multiple systems that don’t talk to one another.

Security gaps open up because of inconsistent permission management. When an external chatbot has access to Teams data but does not follow the same permission rules as SharePoint, sensitive information can leak to unauthorized users. The accountability principle in Art. 5(2) GDPR requires that data protection be demonstrable — from configuration through to daily use. With fragmented tool stacks that proof is almost impossible to produce.

amaiko: the native AI knowledge layer instead of yet another tool

amaiko does not position itself as a replacement for Microsoft 365, but as an upgrade to the existing infrastructure. The solution drapes itself as a native AI knowledge layer with intelligent capabilities over Teams, SharePoint and Outlook. No new user interface, no separate app, no training overhead.

The 3-tier stack model makes the architecture explicit:

1. Native AI knowledge layer (amaiko): persistent memory, proactive knowledge management, context-relevant availability, plus, with the Meeting Notetaker add-on, automatic meeting summaries, live transcription and speaker identification.
2. M365 base infrastructure: Teams, SharePoint, Outlook as the central work environment.
3. Specialized tools: HubSpot, Personio and other domain applications with specific capabilities.

What makes amaiko technically unique is its multi-agent network. While conventional AI assistants typically use a single generic language model, amaiko taps into specialized AI agents. Each one is an expert in its own field — from project management to compliance to technical documentation. They work together in the background to resolve complex requests with greater precision and context than any single AI could.

Automatic knowledge build-up happens out of real interactions. Emails, chats and meetings are analyzed by intelligent analytics, relevant information is extracted, and the result flows into a persistent corporate memory. Unlike classic wikis that fail at manual upkeep, the knowledge grows organically with the daily work.

The GDPR-compliant architecture with German hosting addresses the compliance demands of the mid-market. Under Art. 35 GDPR, a data protection impact assessment (DPIA) is mandatory whenever there is a high risk to the rights of data subjects — which is virtually always the case with modern AI tools. amaiko provides the documentation and transparency required to meet that bar.

Why amaiko is not an IT project: integration vs. implementation

Installation is genuinely simple. Connect your account, get going — no months-long implementation, no external consultancy, no separate employee training. amaiko uses existing SharePoint and Outlook data structures rather than building parallel systems.

The decisive difference compared to session-based chatbots: amaiko keeps a persistent memory. It consolidates your team’s conversations into company knowledge that is personal, team-wide or company-wide, so nobody has to explain the same context twice. That is precisely why the rollout works without tedious prompt training.

The benchmarks speak for themselves: companies report 57% shorter onboarding time for new employees and 35% less time spent searching for information. These efficiency gains arise because knowledge is no longer locked in the heads of individual employees or scattered across documents — it is centrally available and searchable.

Proven innovation from Germany

amaiko is not an experiment but a battle-tested solution for the mid-market. Awarded 2nd place at BayStartUP Ideenreich 2026 and already cherished by more than 200 daily users as their indispensable AI buddy, amaiko offers the security and stability that managing directors look for in their digital transformation.

Workflow check: how your day in Teams changes with an AI buddy

A typical workday begins differently when amaiko is active as your AI buddy. Instead of sorting through emails and trying to get an overview of upcoming meetings each morning, you get a proactive morning briefing: the most important emails are prioritized, relevant information from past meetings is summarized, and upcoming appointments already include the necessary context.

With the Meeting Notetaker add-on, the automated follow-up takes over after meetings. While Microsoft Teams Premium offers basic features such as transcripts and task lists through Intelligent Recap, amaiko goes a decisive step further: the AI knowledge layer feeds those results directly into the persistent corporate memory. Outcomes are not only logged but immediately linked with running projects and the knowledge of other departments. And the best part: amaiko gets better every day, learns your priorities and your style, and adapts to your needs.

The knowledge-retention scenario makes the difference clear: a long-tenured employee leaves the company. Without persistent knowledge management, tacit knowledge is lost — customer relationships, project histories, internal processes. With amaiko, that knowledge stays searchable in Teams. The successor finds the relevant email threads, meeting summaries and decision histories without a manual handover. More on this: How to secure corporate knowledge when employees leave.

Search frustration is universal: you know a piece of information exists but not where. Searching in three SharePoint folders, two Teams channels and the Outlook archive at the same time costs time and nerves. amaiko consolidates these sources in the background and delivers context-relevant results from a single query. External knowledge sources can also be folded into internal support solutions to provide access to the right documents and information from inside Teams.

Proactive knowledge management instead of reactive search

The notion of “knowledge that finds you” is what sets amaiko apart from passive chatbot features. Instead of waiting for queries, the AI assistant recognizes relevant information and surfaces it proactively. Before a customer meeting you automatically receive the history of previous conversations, open items and relevant documents.

The buddy status means amaiko acts like a colleague who thinks along with you. Suggested replies and automated workflows accelerate communication and reduce manual chores.

The integration into natural Teams workflows happens without context switches. You stay in your familiar environment — Teams chats, Outlook emails, SharePoint documents — and get AI support exactly where you need it. No jumping to external platforms, no extra logins.

Security in the mid-market: GDPR and ISO 42001 without a configuration marathon

amaiko hosts in Germany and keeps AI processing inside the EU, for every customer. Microsoft Copilot runs in Microsoft’s EU Data Boundary, and its flex routing, on by default for EU tenants created after 25 March 2026, lets AI processing move to the US, Canada or Australia at peak load. amaiko stays consistently in the EU.

The accountability principle in Art. 5(2) GDPR requires data protection to be demonstrable — from configuration through to daily use — and that demands regular audits and documentation. With amaiko, hosting and AI processing are the same for every customer, so there is no tenant setting to audit.

With external AI tools such as ChatGPT or Gemini, GDPR conformance depends on the right configuration and regular data-protection reviews. amaiko is unequivocally GDPR-compliant and the AI sees only what each user’s own Microsoft 365 permissions allow.

ISO 42001 certification as a quality marker for AI systems is gaining traction in the B2B context. The standard for AI management systems complements the well-known ISO 27001 for information security and addresses the specific risks of modern AI tools. More on this: ISO 42001 – certified or merely aligned?.

The practical implementation of the data protection impact assessment (DPIA) becomes considerably simpler. Companies should ensure that critical AI-supported decisions are subject to human review, in order to meet GDPR requirements. amaiko is designed so that this oversight remains intact.

Comparison: amaiko vs. Microsoft Copilot in a fast rollout

Criterion	amaiko	Microsoft 365 Copilot
Persistent memory	Yes — continuous knowledge build-up across sessions	Per-user memory (preview), stored in each user’s mailbox
Rollout effort	Minimal — direct integration into M365	Higher — license configuration, policy settings, IT approvals
Training need	None — native integration into existing workflows	Prompt training recommended for optimal use
Hosting	Germany, on amaiko’s own infrastructure; AI processing in the EU only	EU Data Boundary today, but “flex routing” can send AI processing to the US, Canada, or Australia — on by default for EU/EFTA tenants created after March 25, 2026; existing tenants must check MC1269223 and opt out
Context retention	Across projects, employees and departments	Per user; the memory stays in that person’s mailbox
Cost	€41.58 per user per month billed annually; briefings and Active Inbox included	Copilot Business €18.20 per user per month billed annually (up to 300 users), add-on to an eligible Microsoft 365 plan; Cowork billed by usage

Advanced AI features in Microsoft Teams, such as Intelligent Recap, require either a Microsoft 365 Copilot license or Teams Premium.

The decisive difference lies in who the memory belongs to. Copilot’s memory is a preview feature that Microsoft stores in each user’s own Exchange mailbox, so it remembers for one person. amaiko builds a persistent corporate memory: knowledge that is personal, team-wide or company-wide and stays when someone leaves.

Choosing the best solution depends heavily on the use case, the data-protection requirements and the specific needs of the users. For companies that value an intuitive system and company-wide, persistent knowledge management, amaiko is the best choice. The full structural breakdown lives in our piece on the difference between amaiko and Microsoft Copilot.

Teams Premium as an interim solution

Teams Premium adds AI features for meetings, such as Intelligent Recap and live translated captions.

Its AI summaries and automatic minutes stay with the individual meeting. Teams Premium offers no persistent knowledge layer across projects.

Migration from Teams Premium to more comprehensive AI architectures is feasible. Companies that start with Teams Premium and later realize they need more can add amaiko as a complementary knowledge layer without disrupting existing workflows.

Common challenges and how to solve them

IT security concerns when integrating AI

The answer lies in German hosting infrastructure and transparent data-protection practices — exactly what amaiko provides. Transparency in AI data processing obliges providers and operators alike to disclose how personal data is processed in order to ensure traceability.

User adoption without training overhead

Native integration into existing workflows eliminates the learning curve. Teams already offers suggestions for short replies in chats based on the prior conversation. amaiko extends that idea without introducing new user interfaces. Employees keep working in Teams, Outlook and SharePoint, with additional AI support layered on top.

Knowledge quality without manual upkeep

Automatic knowledge build-up from real interactions solves the wiki problem. The amaiko AI buddy in Microsoft Teams automates routine tasks such as minute-taking (with the Meeting Notetaker add-on) and continuously improves the knowledge base in the process. Instead of manual documentation, knowledge flows from emails, chats and meetings automatically into the corporate memory.

Compliance during rapid AI adoption

Pre-configured GDPR-compliant settings make a fast rollout possible without a compliance marathon. The settings needed for data protection, data processing and user transparency are already integrated. IT administrators don’t have to configure complex policies by hand.

Conclusion and next steps

Native AI knowledge layers like amaiko offer a sustainable alternative to separate tools that breed shadow IT and force context switches.

Frequently asked questions (FAQ)

Which AI runs directly in Microsoft Teams without a separate installation?

Microsoft 365 Copilot, Teams Premium and amaiko are the central AI solutions that operate seamlessly inside Microsoft Teams. Copilot’s memory belongs to each individual user and Teams Premium’s recaps to each meeting, while amaiko acts as the native AI knowledge layer. It simply lays itself over your entire M365 infrastructure. The decisive difference: amaiko builds a persistent corporate memory that consolidates knowledge from chats, mails and documents automatically and surfaces it proactively — GDPR-compliant on German servers.

How does amaiko differ from Microsoft 365 Copilot?

The central difference is who the memory belongs to. Copilot’s memory is a preview feature stored in each user’s own mailbox, and its scheduled briefings and email-triggered tasks run in Cowork, billed by usage. amaiko consolidates conversations into company knowledge that stays when someone leaves, and its morning briefing and Active Inbox are part of the seat. amaiko is also hosted in Germany, with AI processing exclusively within the EU.

Is amaiko GDPR-compliant, and where is the data stored?

amaiko uses German hosting and is fully GDPR-compliant. Data is stored in Germany and AI processing runs inside the EU only; there is no flex routing into other regions. The platform addresses the accountability principle in Art. 5(2) GDPR through transparent documentation of data processing.

Does amaiko require separate employee training?

No, amaiko requires no separate training. The platform integrates natively into existing Teams, Outlook and SharePoint workflows. Employees stay in their familiar environment and get AI support exactly where they need it. The rollout works without tedious prompt training, because the persistent memory understands the context automatically.

How does the persistent memory compare to session-based chatbots?

Session-based chatbots forget the entire context after every session. Each new conversation starts from zero, and users have to re-explain important information. amaiko, in contrast, stores knowledge continuously, adapts to your style and builds a corporate memory that survives across sessions, projects and employee changes.

What costs are involved compared to Microsoft 365 Copilot?

Microsoft lists Copilot Business, for up to 300 users, at €18.20 per user per month billed annually, as an add-on to an eligible Microsoft 365 plan, so Microsoft’s seat costs less than an amaiko seat. Cowork, which runs briefings and scheduled tasks, is billed by usage on top. amaiko costs €41.58 per user per month billed annually, with the morning briefing, Active Inbox and unlimited tokens included and hosting in Germany.

Can amaiko be integrated with existing tools such as HubSpot or Personio?

Yes. amaiko fits the 3-tier stack model: native AI knowledge layer (amaiko), M365 base infrastructure (Teams, SharePoint, Outlook) and specialized tools (HubSpot, Personio). The integration ensures that knowledge from different sources flows together into a central knowledge layer and is delivered context-relevant.
