Your starting point
“Let users invite a teammate by email. Invitations expire after 7 days. Only workspace admins can send them.”
An admin can invite a teammate by email. A valid invitation grants access to the workspace; an expired invitation grants no access.
Valid → join workspace
Expired → request new invite
Step 1
Open an invitation more than 7 days after it was sent.
Expected result: The workspace remains inaccessible.
Step 2
Request a new invitation.
Expected result: The user sees confirmation of the request.
AI gives you a starting point. You check the assumptions and edge cases before the team builds.
Browse public pagesHow it works
AI starts the draft. You decide when it’s ready.
Create a page and explain the feature in plain words, or paste the meeting notes you already have.
Ask the assistant for requirements, a process or sequence diagram, and initial test cases.
Review assumptions and missing paths. Edit directly or ask the assistant to change the relevant artifacts, then verify the result.
Share the page, discuss specific details in comments and agree on what to build and test.
Why Docion
Requirements, diagrams and tests belong in the same conversation.
Refine the text, change a diagram or adjust a test step. The draft stays editable.
Comment on the exact paragraph, diagram element or test step, and share one page with the team.
Save common blocks in storage, see where they are used and choose when to update their copies.
Who it’s for
Business and systems analysts
Draft requirements and process diagrams from your notes. Check the assumptions with stakeholders and capture their feedback on the page.
Product managers and owners
Turn a backlog idea into requirements and acceptance criteria. Bring a concrete draft to refinement so the team can challenge the details.
QA engineers and leads
Review test cases while the feature is still being defined. Add missing paths and expected results next to the requirements they cover.
Beyond the first draft
Use the same workspace to create, collaborate and maintain your product documentation.
For developers
Connect your coding assistant to your Docion space over MCP. It can read requirements, diagrams and tests, and help update documentation as the implementation changes.
Uses your connected assistant. No Docion AI credits are consumed.

Before you start
Treat it as a first draft. Check assumptions, business rules, alternative paths and expected results with your team before implementation.
You can ask the assistant to revise related artifacts. Review those changes yourself; do not assume every dependent artifact updates automatically.
Every new user gets $10 in AI credits to test the assistant. Documents, diagrams, test cases and collaboration remain free to use manually. Pro adds more AI credits, version history and backups.
A self-hosted deployment is available, with source access and offline operation. Contact us to discuss deployment and the connectivity needed for your chosen AI provider.
Sign in with Google or email and create a page. Use your $10 in trial credits to ask the AI for requirements, diagrams and test cases, then review and refine the draft.
