Langdock vs WRITER

Langdock

Langdock sells the thing European enterprises actually need before they can roll out AI: one assistant across the company, hosted in the EU, with admin controls, audit and no single-model lock-in. The customer list (Merck, BASF, Der Spiegel) and the compliance certifications back that up. The pricing is where to look closely — the EUR 25 seat is only the base, and workflows, governance and API tokens are three separate meters on top.

Pros

• +Model-agnostic, so the underlying provider can change without a migration
• +EU hosting with ISO 27001, SOC 2 Type II and GDPR compliance
• +Cloud or on-premise deployment, plus custom branding
• +Chat, agents, workflows, integrations and API in one platform
• +Web, iOS and Android clients, and a 7-day trial with no card

Cons

• −Four separate meters: seats, workflow runs, governance and API tokens
• −The workflow add-on starts at EUR 539/month, far above the seat price
• −Governance is free only until January 2027, then EUR 3.50 per user per month
• −Priced in euros, so the dollar cost moves with the exchange rate
• −Enterprise pricing above 1,000 users requires a sales conversation

WRITER

WRITER is built for large marketing, sales and support organisations that want governed AI agents tied to their own data and brand rules, with admin controls that security teams expect. Individuals and small businesses looking for an inexpensive writing assistant will find it oversized and hard to price without talking to sales.

Pros

• +Governance features such as audit logs, guardrails and role-based access
• +Knowledge Graph and connectors ground outputs in company data
• +Own Palmyra models with the option to use other LLMs
• +14-day free trial of Starter without a credit card

Cons

• −No published price for any plan
• −Starter is capped at 5 users, 5 Playbooks and 3 active connectors
• −Most advanced orchestration and connectors are Enterprise-only
