Quartal Messages

Companies own the data; persons, advisors and AI agents with MCP tools and UI widgets take part in the conversations

Communication between humans and agents.

A modern and secure real-time threaded chat, optimized for hundreds of customers and their advisors together with AI agents. Every party is authenticated, and all the conversations are owned by the customer company.

  • Agents take part in the conversation, alone or supporting the humans
  • Agents show widgets in the thread: reports, forms and other interactive user interfaces
  • Advisors act on behalf of the company, with the rights governed for them
  • Embed it into your own service, or connect to Slack, email, WhatsApp and more

Quartal IAM

Users authenticate with strong authentication; companies are checked from the company registry and Suomi.fi authorizations

European authentication and authorization for Service-as-Software.

  • National strong authentication for people, verified company data and GDPR built in
  • Authorization optimized for managing hundreds or thousands of customer companies: customer groups, advisor teams, roles and row-level security
  • The same security rules for agents and automations as for people
  • Single sign-on with OAuth 2.0, OpenID Connect and SAML, on open-source Keycloak

Quartal Plugins

Define agentic logic once, use it from anywhere.

Plugins package the business logic for agents: tools, widgets, agent skills and agents. Quartal Hub comes with the financial management plugins included, and you can add partner and community plugins, or package your own. Quartal Plugins is open source.
