Top 5 Microsoft 365 Copilot Alternatives (2026)

Companies look for a Microsoft 365 Copilot alternative for reasons Microsoft documents itself. Copilot runs in the EU Data Boundary, and flex routing, on by default for EU tenants created after 25 March 2026, lets its AI processing move to the US, Canada or Australia at peak load. Data residency in Germany needs the Advanced Data Residency add-on on 100% of your paid licences. Copilot’s memory is in preview and is stored in each user’s own mailbox. Its daily briefings, scheduled prompts and email-triggered tasks run in Copilot Cowork, which is billed by usage. And Copilot is an add-on: Microsoft sells it only with an eligible Microsoft 365 plan underneath.

For a company in the German Mittelstand that adds up to a setting to audit, knowledge kept per person and a bill that grows with use. We cover where Copilot stands on GDPR in 2026 separately. Here are five alternatives. For the direct head-to-head, see amaiko vs Microsoft 365 Copilot.

1. amaiko: knowledge that stays, hosted in Germany

amaiko lives in Microsoft Teams, in the chat your company already uses. There is no separate app tab, no browser extension and no new tool to learn, and it needs no Copilot licence.

amaiko builds a persistent corporate memory. Every night it consolidates your team’s conversations into lasting company knowledge: projects, customers, decisions and who knows what. Knowledge can be personal, team-wide or company-wide. It learns how each person works and gets better every day. When someone leaves, what they knew stays. amaiko teams spend 35% less time searching, and new hires get up to speed 57% faster.

That memory feeds a multi-agent network: specialists for email, calendar, documents, research and your business systems. The marketplace adds HubSpot, Dynamics 365 Business Central, Personio, Jira, Confluence, DATEV and more, and amaiko can orchestrate several systems in one request.

And amaiko works before you ask. Your morning briefing is ready when your day starts, Active Inbox reads incoming email and flags what needs attention, and flagged emails become to-dos. It is part of the plan, with unlimited tokens, at no extra cost.

amaiko is GDPR-compliant and hosted in Germany on its own infrastructure, not in the Microsoft cloud, with AI processing only inside the EU, for every customer. Details are on the security page. It costs €41.58 per user per month billed annually (€499 per user per year), or €49.90 monthly. A 10-person company pays €4,990 a year. Copilot Business costs less per seat, at €18.20 billed annually, before Cowork usage and on top of a Microsoft 365 plan. See pricing.

2. ChatGPT Enterprise

ChatGPT Enterprise is OpenAI’s company plan. Its price is not published: the pricing page sends you to sales. Your team works in ChatGPT. Its Microsoft Teams app connects Teams to ChatGPT so it can search your chats on request, and your Microsoft Entra admin has to approve its permissions.

3. Langdock

Langdock is a model-agnostic AI platform in its own application, in the browser or as a desktop app. In Microsoft Teams it answers through a bot whose conversations do not appear in the Langdock web app’s history. Its Business seat costs €23.20 per user per month billed annually, within a 5-hour session limit and a weekly limit; Business Max, with five times those limits, costs €99.

4. meinGPT

meinGPT is an AI platform with chat, assistants and meeting notes. Its price page shows €18 per user per month for up to 50 users, with the 10% annual discount included. Model costs are not in that price; the calculator adds a model budget on top, preset at €2.31 per user. Your team works in meinGPT’s own interface: its Teams connector is read-only and does not post messages.

5. Glean

Glean is an enterprise AI platform with no public price list. Its own comparison with Copilot gives the typical cost as “Approximately $50 per user per month, plus approximately $15 for AI features”. According to its region documentation, Glean-hosted tenants default to us-central1 in the US, and a non-preferred region such as Frankfurt raises the subscription.
