Note-taking

Elium vs OneNote

OneNote is great at what it was designed for: one person's notes and meeting capture. Elium is the trusted knowledge platform for what comes next – one governed source your teams and your AI answer from.

Governed foundation

Articles the organisation owns, not pages one person keeps

In Elium, every article has a named owner, a review date and an attributed edit history – no conflict pages, no silent overwrites. OneNote pages belong to their author. Elium articles belong to the organisation, with the governance to keep them verified, current and governed.

  • A named owner on every article
  • Attributed versions – no silent overwrites
  • Review dates and validation flows built in

AI you can stand behind

AI answers grounded in knowledge you govern

Point Copilot, your own agents or Elium's built-in AI at one governed source. Every answer cites the article it came from, and permissions are respected in every response. AI is only as reliable as the notebooks it reads – Elium makes sure what it reads is verified and current first.

  • Every answer cites its source article
  • Permissions respected in every AI response
  • Workswith Microsoft Copilot, agent platforms and Elium's own AI

Delivered everywhere

One source, served wherever your teams work

Elium serves answers inside the tools your teams already use – Teams, Slack, ITSM tools, portals and your own apps through the API – in every language you work in. Structured content types too: procedures, decision trees and policies, not just freeform pages.

  • Served in Teams, Slack, ITSM tools and portals
  • Procedures, decision trees and policies – not just pages
  • Multi-language publishing and translation built in

Knowledge that outlives turnover

When people move on, their knowledge stays

When a notebook owner leaves, their knowledge often leaves with them. In Elium, articles have owners, attributed history and a transfer flow – so when someone moves on, their knowledge gets a new owner instead of a locked account. That is continuity, built in.

  • Ownership transfers when people leave or change roles
  • Attributed edit history on every article
  • Usage analytics show what still matters

The success of a knowledge base depends mainly on the involvement of the staff, who have to write, correct and update articles on a very regular basis. So we needed a tool that was dynamic, user-friendly and easy to use. Elium meets these criteria perfectly.

Elium has become the concrete embodiment of the collaborative spirit implemented within Eura Nova. People intuitively perceived that their inputs to the project were efficiently tackled, and that they were clearly invited to take part in the action through it.

FAQ

Questions we hearfrom teams switching from OneNote

Yes. OneNote sections can be exported and imported into Elium. Migration is also the right moment to restructure – a notebook layout that worked for one person rarely fits a team. Start with a migration assessment: we map your notebooks and give you a clear plan.
Yes. Elium serves answers inside Teams and other workplace tools through integrations and open APIs. The model is answer-first rather than notebook-embedded – your teams get the current answer where they work.
Elium is not a stylus notebook – it is a knowledge platform. Many teams keep OneNote for meeting capture and personal notes, and use Elium for the shared, governed knowledge those notes feed into.
It becomes one when more than one person maintains them, when concurrent edits create conflict pages, or when a procedure has to outlive its author. Elium gives procedures owners, review dates and a versioned history – none of which OneNote enforces.
Probably, if one person's notebooks genuinely cover it. Elium lands when knowledge has to scale beyond a single owner – multi-team, multi-language, regulated, or feeding an AI.
