Langdock vs Dust: Pricing, Teams Fit, and What Each One Actually Costs

Langdock and Dust solve the same problem from opposite ends — Langdock is a chat-and-workflow layer priced per seat with usage tiers, Dust is an assistant-building platform with a flat Pro price and a selectable EU region — and if your company already lives in Microsoft Teams, amaiko is the third option that neither of them is: native rather than integrated, with a memory that accumulates without anyone configuring it.

What you will take away from this article:

• Langdock lists €25 per user/month (Business) and €99 (Business Max, 5× usage), plus a €539/month workflow add-on beyond 2,500 runs and a 10% token markup on API usage.
• Dust is roughly $29 per user/month on Pro with EU-or-US hosting selectable, SOC 2, and zero data retention with model providers.
• Dust has a native Microsoft Teams integration. Langdock does not — it is a separate app.
• The cost neither price list shows is build effort: both platforms deliver value in proportion to how much time someone spends creating and maintaining agents.
• Neither accumulates a corporate memory on its own. Both are reactive: every interaction starts with a user.

What does Langdock actually cost?

The published Langdock pricing starts at €25 per user per month on Business, rising to €99 for Business Max with 5× usage. Three line items decide the real number:

• Workflow runs. 2,500 are included. Beyond that, 100,000 runs cost €539 per month as an add-on.
• API usage carries a 10% token markup.
• The usage ladder. Business Max exists because Business runs out. Which tier you land on is discovered in production, not at purchase.

For a 100-person organization, the seat cost alone is €2,500 per month before the first add-on. That is the figure worth modelling, not the €25.

Langdock is a genuinely good product for what it is — a European, multi-model chat layer with workflows on top. But it is a separate application. Your team leaves Teams to use it, which reintroduces the context-switching tax the tool was supposed to remove.

What does Dust actually cost?

Dust is around $29 per user per month on Pro — flatter and easier to model than Langdock’s ladder. Founded by ex-OpenAI and ex-Stripe engineers and backed by Sequoia, it builds department-level assistants connected to Slack, Google Drive, Notion, Confluence and GitHub. It offers a selectable EU or US hosting region, SOC 2, and zero data retention with model providers. It also has a native Microsoft Teams integration, which Langdock lacks.

The cost that does not appear on the price list is the one that matters: somebody has to build the assistants. Dust returns value in proportion to the time invested in creating, refining and maintaining them. For a company with an engineer who enjoys that work, this is a feature. For a 60-person Mittelstand firm with no spare platform engineer, it is an unfunded project.

Note also what “selectable EU region” means: EU hosting is a configuration you choose, not a property of the product. A setting that can be selected can be misconfigured — which is a different risk profile from an architecture with one jurisdiction.

Langdock vs Dust: which one fits?

Criterion	Langdock	Dust	amaiko
Entry price	€25/user/month	~$29/user/month	€29.91/user/month, billed annually
Cost ceiling	€99 tier + €539/month workflow add-on + 10% API markup	Flat Pro price	Flat; no usage ladder
Microsoft Teams	Separate app	Native integration	Native — no separate app
EU hosting	German/EU	Selectable EU or US region	Own German infrastructure, EU-only processing
Setup effort	Agents configured per use case	Assistants built and maintained	Works out of the box
Corporate memory	None that accumulates on its own	Per-assistant, built	Persistent, accumulates automatically
Mode	Reactive	Reactive	Proactive briefings without prompting

Choose Langdock if you want a European multi-model chat layer with workflow automation and you are comfortable modelling the usage ladder. Choose Dust if you have the engineering appetite to build assistants and want connectors into Slack, Notion and GitHub rather than Microsoft 365.

Book a demo if you would rather not choose between a separate app and a build project.

What do Langdock and Dust have in common?

This is the more useful comparison, because it is the part that does not show up in a feature grid.

Both are reactive. Every interaction begins with a person deciding to ask. That sounds unremarkable until you look at adoption: the tools stop being used the moment the novelty fades, because remembering to open them is itself work. This is the mechanism behind why employees ignore Copilot, and it applies equally to any pull-based assistant.

Neither builds a memory by itself. Both can be pointed at your documents. Neither accumulates what your company learns — decisions, context, who owns what — unless somebody encodes it. A retrieval layer answers from documents; it does not remember that the pricing question was settled three weeks ago. That distinction is the subject of what persistent AI memory actually means.

Both price the software and not the project. The seat cost is visible. The person configuring agents is not.

Where does amaiko fit?

amaiko is the Teams-native option: €29.91 per user per month billed annually, running inside Teams and Outlook with no separate app, no new portal and no training course. It is more expensive than Langdock’s €25 entry — that is the honest comparison — and the argument for it is total cost rather than entry price. There is no usage ladder, no workflow add-on, no token markup, and no agent-building project to staff.

It runs on our own infrastructure in Germany, with EU-only processing. Not a region you select — the only way it runs. amaiko is GDPR-compliant and aligned with ISO 42001; the detail is on the security page. In production this measures as 57% shorter onboarding and 35% less time lost to searching, across 200+ daily users.

For strict data requirements, amaiko liberté at €44.87 per user per month runs exclusively Mistral models with every token processed in the EU.

Frequently Asked Questions

How much does Langdock cost per user?

€25 per user per month on the Business plan and €99 on Business Max, which includes 5× the usage. Workflow automation beyond the included 2,500 runs is a €539 per month add-on for 100,000 runs, and API usage carries a 10% token markup. A 100-person organization pays €2,500 per month in seat costs before any add-on.

How much does Dust cost?

Around $29 per user per month on the Pro plan, which is flatter and easier to model than Langdock’s usage tiers. The cost that is not on the price list is the time required to build and maintain the assistants, since Dust delivers value in proportion to that investment.

Does Langdock or Dust work inside Microsoft Teams?

Dust has a native Microsoft Teams integration. Langdock does not — it is a separate web application, so your team leaves Teams to use it. An integration surfaces an external tool inside Teams; a Teams-native product has no outside application to surface.

Which one is better for GDPR and EU data residency?

Langdock hosts in Germany and the EU. Dust offers a selectable EU or US region, which means EU hosting is a configuration rather than a property — a setting that can be selected can also be misconfigured. amaiko processes exclusively in the EU on its own German infrastructure, with no US option to configure incorrectly.

Do Langdock and Dust build a corporate memory?

Neither accumulates one on its own. Both can retrieve from connected documents, and both let you build assistants that carry instructions, but company knowledge — decisions, ownership, context from previous conversations — does not accumulate unless someone encodes it deliberately.

What is the cheapest of the three?

Langdock’s €25 entry price is the lowest headline number. Whether it is the cheapest at your size depends on workflow runs and which usage tier you end up on, because the €539 add-on and the €99 tier are where the cost actually lands. amaiko is €29.91 per user per month billed annually with no usage ladder or add-ons, so the entry price is also the running price.
