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 limits, Dust is an agent-building platform priced per seat with monthly credits 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 across the company without anyone configuring it.

What you will take away from this article:

• Langdock lists €23.20 per user/month billed annually (Business, first 50 seats) and €99 (Business Max, 5× usage), with a session and a weekly usage limit per seat and a workflow package at €449/month billed annually for 40,000 runs beyond the 2,500 included.
• Dust lists €24 per user/month billed annually on Pro and €120 on Max, each seat with a monthly credit allowance; once it and the prepaid workspace pool are used up, the member is blocked. EU or US hosting is selectable, and Dust holds SOC 2 Type II.
• Both reach Microsoft Teams through a bot that answers when someone mentions it, and both are separate applications.
• The cost neither price list shows is build effort: on both platforms, someone has to create and maintain the agents.
• Neither builds a corporate memory: both remember per user at most, and both act on their own only for tasks someone has set up on a schedule or trigger.

What does Langdock actually cost?

The published Langdock pricing lists €23.20 per user per month billed annually on Business (€28.89 monthly) for the first 50 seats, rising to €99 for Business Max with 5× usage. Three line items decide the real number:

• The usage ladder. Every seat has a 5-hour session limit and a weekly limit. At the limit, a workspace without its own model keys drops to GPT-5.6 Luna until the window resets, unless it pays for Extra Usage by the token. Which of your people need Business Max shows up in production, not at purchase.
• Workflow runs. 2,500 a month are included. Beyond that, the workflow package costs €449 per workspace per month billed annually for 40,000 runs (€539 monthly), or €999 for 100,000 (€1,199 monthly).
• AI usage inside workflows is billed per token, even when AI models are included in the seat.

For 25 people, the Business seats alone come to €580 per month before any of that, and €2,475 if they all need Business Max. That range is the figure worth modelling, not the €23.20.

Langdock itself is a separate application, in the browser or as a desktop app. Its Teams bot answers in channels only when tagged, and Teams conversations do not appear in the web app’s chat history, so the real work still happens in another tab, which reintroduces the context-switching tax the tool was supposed to remove.

What does Dust actually cost?

Dust lists €24 per user per month billed annually on Pro (€30 monthly) and €120 on Max (€150 monthly), excluding VAT, with 8,000 or 40,000 credits per seat per month that do not roll over. On the Business plan there is no pay-as-you-go: a member who uses up their seat’s credits draws on a workspace pool your admin buys in advance, and once both are gone, they are blocked from sending messages. Dust connects to 20+ data sources, led by Slack, Notion, GitHub and Google Drive, plus any tool via MCP. Its security page lists hosting in the EU or the US, SOC 2 Type II and zero data retention with model providers. In Microsoft Teams, Dust is a bot your admin uploads as a custom app, and its agents see only the conversations where someone mentions them.

The cost that does not appear on the price list is the one that matters: somebody has to build the agents. Dust’s pricing page calls Dust “the platform for AI Operators”, people who “build it with judgment, deploy it, and run it for their whole team.” In a 60-person Mittelstand firm with no spare platform engineer, that work comes on top of someone’s actual job.

Dust’s EU option is a region you select, and its security page names no country. For your data protection officer that means one more question for Dust: in which country an EU workspace is stored.

Langdock vs Dust: which one fits?

Criterion	Langdock	Dust	amaiko
Entry price	€23.20/user/month, billed annually	€24/user/month, billed annually	€41.58/user/month, billed annually
Cost ceiling	€99 tier + usage limits + €449/month workflow package	€120 tier + prepaid workspace credits	Flat; no usage ladder
Microsoft Teams	Bot that answers in channels when tagged; separate app	Bot that sees only mentions; separate app	Native, no separate app
EU hosting	Azure in the EU (Frankfurt); “global” models may run outside the EU	Selectable EU or US region	Own German infrastructure, EU-only processing
Setup effort	Agents configured per use case	Agents built and maintained	Works out of the box
Corporate memory	Per account, regular chats only	Per user, private to each	Personal, team and company knowledge, consolidated nightly
Mode	Reactive, plus tasks you schedule	Reactive, plus schedules and triggers you set up	Proactive briefings without prompting

With amaiko that entry price is also the running price; the full per-user calculation against Microsoft 365 Copilot is worked through in what amaiko costs per user in everyday Microsoft 365 work.

A company that runs on Teams and Outlook gets further with the option that needs neither a separate app nor 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 conversation begins with a person deciding to ask; the exceptions are tasks someone set up in advance on a schedule or, in Dust, a trigger. That sounds unremarkable until you look at adoption: when using a tool means remembering to open it, use fades with the novelty, one of the reasons employees ignore Copilot.

Neither builds a company memory. Langdock remembers per account and Dust per user, and both can be pointed at your documents. Neither accumulates what your company learns — decisions, context, who owns what — across people 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: €41.58 per user per month billed annually (€29.91 billed annually for new customers until 31 December 2026), running inside Teams and Outlook with no separate app, no new portal and no training course. On the price sheet it sits above Langdock’s €23.20 and Dust’s €24, and the argument for it is total cost rather than entry price. There is no usage ladder, no credit top-up, no workflow package, and no agent-building project to staff.

It stores data on our own infrastructure in Germany, with EU-only AI processing. The storage region is not a setting you select — it is always Germany. 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 runs exclusively Mistral models with every token processed in the EU, at the same price as amaiko.

Frequently Asked Questions

How much does Langdock cost per user?

€23.20 per user per month billed annually on the Business plan (€29 monthly) for the first 50 seats, with volume discounts above that, and €99 on Business Max, which includes 5× the usage (€119 monthly). Every seat has a 5-hour session limit and a weekly limit; at the limit, a workspace without its own model keys drops to GPT-5.6 Luna unless it pays for Extra Usage by the token. Workflows beyond the included 2,500 runs a month cost €449 per workspace billed annually for 40,000 runs (€539 monthly), and AI usage inside workflows is billed per token on top.

How much does Dust cost?

€24 per user per month billed annually on Pro (€30 monthly) and €120 on Max (€150 monthly), excluding VAT. Each seat carries a monthly credit allowance that does not roll over. On the Business plan, a member who uses it up draws on a workspace pool the admin buys in advance and is blocked from sending messages once both are exhausted. The cost that is not on the price list is the time someone spends building and maintaining the agents.

Does Langdock or Dust work inside Microsoft Teams?

Both are separate applications that reach Teams through a bot. Langdock’s bot answers in channels only when tagged, cannot be used in direct messages between colleagues, and its Teams conversations do not appear in the web app’s chat history. Dust’s bot is uploaded by an admin as a custom app, and its agents see only the conversations where someone mentions them. amaiko runs in Teams and Outlook with no outside application.

Which one is better for GDPR and EU data residency?

amaiko stores data on its own infrastructure in Germany and processes AI exclusively in the EU, with no hosting region to select. Langdock says it hosts via Microsoft Azure on servers in the EU, in Frankfurt according to its terms, and that models with a “global” deployment may run inference outside the EU. Dust offers hosting in the EU or the US; its security page names a region, not a country.

Do Langdock and Dust build a corporate memory?

Neither builds one for the company. Langdock’s Memory belongs to one account and is unavailable in Project and Agent chats; Dust’s agent memory is private to each user and kept separately for each agent. Both can retrieve from connected documents, but decisions, ownership and context from earlier conversations do not accumulate across people unless someone encodes them. amaiko consolidates conversations into personal, team and company knowledge every night, without anyone configuring it.

What is the cheapest of the three?

Langdock’s €23.20 billed annually is the lowest headline number, with Dust at €24. Whether either is the cheapest at your size depends on usage limits, credits and workflow runs: the €99 Business Max seat, the €120 Max seat, prepaid credit top-ups and the workflow package are where the cost lands. amaiko costs €41.58 per user per month billed annually, with unlimited tokens at a fixed price and no credits to buy, so a heavy user costs the same as a light one.
