About
Nuclino is a Munich-based team knowledge base and wiki platform, offering a clean, lightweight alternative to Notion for documentation, meeting notes, and internal wikis.

Frequently asked questions
What does Nuclino do?
Nuclino is lightweight team wiki and knowledge base — a german alternative to notion and confluence. It is listed under collaboration and knowledge management on EU Alts because its core functionality serves teams looking for a European collaboration tool with EU data residency, typically as a switch away from Notion.
Is Nuclino GDPR compliant?
Nuclino is headquartered in Munich, Germany and falls under EU jurisdiction, so it likely processes user data under the GDPR by default. Customer data processing is supervised by Germany's data protection authority, the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI). EU Alts has not independently verified Nuclino's exposure to the US CLOUD Act, so we can't confirm it either way.
How do teams switch from Notion to Nuclino?
Teams considering a move from Notion to Nuclino are usually drawn by its collaboration workflow fit. EU Alts has not independently verified Nuclino's exposure to the US CLOUD Act, so treat any CLOUD Act or Schrems II conclusions as provisional. Plan a migration in stages regardless: export your data from the US incumbent, pilot Nuclino with a small team, then move the rest once integration coverage is confirmed.
