Langdock Alternative: Ziya ONE Compared

Langdock is an established AI platform from Berlin and, for many companies, a good way into AI. Ziya ONE is the alternative for companies that need more than an AI workspace in a chat: their own AI apps for their processes, local AI without being a corporation, and one partner from strategy to operations.

The short version

Langdock

Langdock is a good fit if you want to roll out a model-agnostic AI chat with agents to many employees quickly, prefer to start self-service, and care about certifications such as ISO 27001 and SOC 2.

Ziya ONE

Ziya ONE is the better fit if your most important use cases are not solved in a chat but need their own apps with their own interface. Or if your data has to stay 100 % in-house but you do not have 5,000 employees. Or if you want strategy, implementation and training from one source.

Where Ziya ONE fits

Langdock and Ziya ONE both have an agent chat for every employee. The difference is underneath: in Ziya ONE the chat is one app of many on ZiyaOS, and every further app uses the same connections, permissions and models.

The chat is one app of many.

Every alternative has a gap.

Most routes are strong as a platform or strong as an app. ZiyaOS brings both together: a core with governance and real apps for your users.

A core with permissions, connections and cost control. On top of it, real apps for your users.

Both run on the same core, with the same permissions, the same connections and the same cost control.

For every process an app, all on one core.

An app instead of a prompt lottery.

In a chat, the result depends on how well someone asks. An app sets the path: the buyer in purchasing uploads the quote, clicks Check and gets the comparison with her framework contracts.

Your process is on no one else's roadmap. Connections, permissions, models and audit logging come with the AI operating system, and your team concentrates on what only you know.
