Langdock or Microsoft 365 Copilot: which one for a company on Microsoft 365?

Langdock is an EU-hosted AI workspace with chat, agents and workflows across many models. Microsoft 365 Copilot is the AI layer inside Word, Excel, Outlook and Teams, sold as an add-on to a Microsoft 365 licence. The deciding difference: Copilot works where your files already are; Langdock gives you model choice and a fixed EU hosting promise without Microsoft's peak-time routing.

Pick Langdock if…

  • You want a fixed EU hosting promise with no peak-time routing outside the EU.
  • You want to compare or switch between OpenAI, Anthropic, Google and Mistral models.
  • Your team is not all on Microsoft 365, or you want workflows with triggers and approvals without Copilot Studio credits.

Pick Microsoft 365 Copilot if…

  • Your work lives in Word, Excel, Outlook and Teams and you want AI inside those apps, not in a separate tab.
  • You want to buy through your existing Microsoft agreement and reuse Purview, DLP and retention policies.
  • You need Copilot to read your mailbox, calendar and SharePoint with the same permissions your users already have.

Where each one falls short

Langdock

  • Usage is metered in 5-hour and weekly windows; at the limit Langdock drops to a lighter model unless extra usage is enabled (Langdock docs, fair usage policy).
  • Langdock does not sit inside Office files. It reaches Microsoft 365 through integrations and a Teams bot, so editing a document in place is not the model (teamazing 90-day test, updated 17 Aug 2026).

Microsoft 365 Copilot

  • Researcher is capped at 25 queries per user per month, cannot take images as input, and cannot be customised with Copilot Studio (Microsoft Learn, Researcher FAQ, updated 18 Aug 2026).
  • Flex Routing sends model processing outside the EU Data Boundary when EU capacity is tight. It is on by default for EU tenants since 17 Apr 2026; admins must opt out (Microsoft message centre MC1269223).

Langdock or Microsoft 365 Copilot: the verdict

If you are a Microsoft shop and want AI in the apps people already open, Copilot is the natural buy; the price sits near Langdock's and the admin story is deeper. If you need a strict EU hosting promise, model choice, or workflow automation without a second credit system, Langdock is the cleaner choice. Many DACH companies run both: Copilot in Office, Langdock as the model-agnostic workspace.

A third option

If you want the work done, not a chat window

Both tools above give a person a place to prompt. If the team's real need is a competitor report, a campaign plan or the Monday performance PDF, that is a different product: a coworker you brief, a board the team sees, a file at the end. Sokosumi is a marketplace of named AI coworkers for marketing teams, built by Serviceplan Group with NMKR in Munich. Coworkers can be @mentioned in a channel; the task shows on a shared board and ends with a PDF, deck, spreadsheet or dashboard.

  • 52 coworkers and agents from 7 vendors; each profile names the vendor, the models and the hosting region.
  • Free: 250 credits per seat per month, no card. Paid seats €25, €75 or €200 per month; credits are used only when a task runs.
  • Scheduled tasks and finished files, so nobody has to re-prompt on Monday.

Langdock vs Microsoft 365 Copilot: questions

Do I need a Microsoft 365 licence for Copilot?+

Yes. Copilot Business is an add-on to a qualifying Microsoft 365 plan. Microsoft also sells bundles: Business Standard with Copilot at $23.50 and Business Premium with Copilot at $32 per user per month, annual.

Is Copilot data kept in the EU?+

Data at rest stays in the EU Data Boundary. Model processing can move outside the EU at peak demand under Flex Routing unless your admin disables it. Anthropic models inside Copilot are excluded from the EU Data Boundary.

Can Langdock work inside Teams?+

Yes. Langdock has a Teams bot and a Slack bot, so people can use models and agents from a chat window. It does not edit Word or Excel files in place.

Which one produces finished files for a team?+

Copilot creates Office files for the person who asked. Langdock returns chat output and files to the user. Neither puts finished work on a shared board; products such as Sokosumi are built around that.
