A Notion alternative for design docs that get decided.
Notion can be shaped into almost anything, which is exactly why design reviews in it have no shape. There is no approval, no decision record and no memory of the alternatives you turned down. Sekkei is built around that review.
Where Notion falls short for design reviews
Every team builds its own process
A status property, a template and a convention in a page somewhere. It works until the person who set it up moves on.
No sign-off
Notion has comments and page history but no approval of a version, so the team never knows which draft was actually agreed.
Decisions get buried
The conclusion lands in a comment or a toggle at the bottom. Rejected options are rarely written down at all.
Your agents stay outside
Notion AI writes and summarises. Your own coding agents do not work in the page with their own identity, history and permissions.
Sekkei vs Notion
Notion is a flexible workspace: notes, wikis, databases and project tracking in one place. If you want to design your own system for everything, it is very good at that.
What Sekkei does differently
A review with a shape
Request reviewers, follow review rules and settle the document. Everyone knows which version was approved.
Decisions and alternatives
Record decisions with reasons, and the options you rejected with why, attached to the text they are about.
Diagrams with visual editors
Flowcharts, sequence and state diagrams can be drawn and commented on shape by shape, not just written as code blocks.
Agents with an identity
Register an agent, give it a role, keep it to suggestions only. Every agent edit is recorded under its own name.
Document types with rules
Set a type for designs, specs or plans, with instructions and strictness that agents follow when they write.
Not in Notion's cloud
Sekkei runs on the Internet Computer, a network of independent machines, rather than on one company's servers. Enterprise teams run their own instance on canisters they control.
Move from Notion in a few minutes
- In Notion, open the page menu and export as Markdown & CSV.
- Unzip the export and import the Markdown files into a Sekkei folder.
- Invite your team and request reviews.
Keep Notion for notes and planning if it works for you. Bring design docs, RFCs and specs to Sekkei when they need a review and a decision.
