Integrations

Sparks provides all backend components – or you connect what you already run: from full sovereignty and your Matrix backend to hybrid with Microsoft 365 or your own Exchange and SharePoint. Word, Excel and Outlook can stay on the desktop – Sparks brings chat, video, calendar and AI together in one interface, usually without migrating data.

Default

Sparks provides all backend components

Office Add-in

Sparks inside Outlook

If Outlook remains your mail and calendar client, you can schedule Sparks online meetings without switching apps: the Sparks Outlook add-in (Office.js) extends Outlook desktop, Outlook on the web, and New Outlook for Windows – similar to the “Teams meeting” button.

Available as an Office add-in (React + Office.js). The meeting button and calendar task pane are implemented; create appointment from email, dual-write to the Sparks Cloud calendar, and RSVP sync are in progress.

What the add-in does today

  • Sparks meeting in appointments

    When composing an Outlook appointment, the “Sparks meeting” button inserts a join link, meeting ID, and invitation block – including meeting options (lobby, E2EE, etc., depending on plan).

  • Sparks calendar task pane

    The ribbon opens a compact Sparks calendar panel: view events and manage Sparks appointments without leaving Outlook.

  • Connected to Sparks backends

    Authentication via Entra SSO or Keycloak; appointments and online meetings use the Sparks account API and appointment manager – compatible with Exchange/M365 hybrid setups.

  • Central rollout

    Deploy as an integrated app in the Microsoft 365 admin center or sideload for pilots. Production hosting: outlook-addin.sparks.team.

In development

  • Create an appointment directly from an email (carry over recipients as attendees)
  • Dual-write: appointment also in the Sparks Cloud calendar (Postgres)
  • Sync RSVP status between Sparks and Outlook

The principle: connect, don't migrate

Sparks is not a new silo. It connects to your existing backends and leaves your data where it is – or you use the native Sparks Cloud calendar (EU Postgres) without an external calendar source. Exchange data stays in Exchange. Google data stays in Google. Nextcloud data stays in Nextcloud. Sparks is the frontend that brings everything together.

Data stays in your backends – Sparks is the frontend.

No other provider can do this

AI assistant with real context from all backends

The Sparks assistant accesses calendars, chats, tasks and files from all connected backends – simultaneously. Questions like "What are my tasks for today?" or "Summarise the Nextcloud document we discussed in the last meeting" are answered with real context – not hallucinations.
