synoia or Notion?
An all-in-one cloud workspace for docs, wikis and databases.
The short answer
Pick Notion for the richest all-in-one workspace, with databases, templates and a built-in AI, if you're content for your knowledge to live in Notion's format and cloud. Pick synoia if your knowledge has to stay as files you own, shared folder by folder, with each person's own AI.

Yes, No and Partly describe Notion as we found it in September 2026, from Notion's pricing, help and developer pages. Products change; check with Notion before you rely on a line here. For synoia, each line describes the product as built today. Nothing is released yet.
Where Notion is the better choice
Breadth. Databases and wikis in one place, an AI built in, and mobile apps that work offline. For a team that already lives in Notion and doesn't need its knowledge as files, it's the more complete product by a distance.
Where synoia fits
Ownership, and a boundary you can explain. Your notes are files on your computers. Folders can be restricted to the people who need them. Your own AI, bound to your access. A service in London. The answer to “where does our knowledge go?” fits in one sentence.
Switching
Can you switch?
Notion can export pages as Markdown and databases as CSV. Moving an export into synoia is something we'll test with pilot members. Leaving synoia is simpler: your notes were always files.
Questions
Can synoia do databases?
No. Notes have properties and tags, but there are no database views. If your work is mostly databases, Notion is the better tool today.
Does Notion offer UK data residency?
We didn't find a UK option in September 2026. Notion offers EU data residency on Enterprise. Check with Notion before relying on this.
