How it works
We assemble a structured brief
Your inputs are organized into the standard sections a designer expects: users, goals, flows, constraints, priorities, and success metric.
Get a completeness score
Each section is scored for genuine detail, not just presence, so a thin one-line answer scores lower than a specific one — giving you a clear signal on what to fill in before handoff.

Frequently asked questions
Does UX Brief AI use real AI to write my brief?
No. UX Brief AI assembles a structured brief and completeness score entirely from the text and lists you type in. It does not run a real AI/LLM generation step, and it does not read your existing product, designs, or documents — everything in the output comes from your own inputs.
What makes a section score low even if I filled it in?
The scoring checks for genuine detail, not just a non-empty field. A one- or two-word answer for target users or primary goal scores partial credit; a specific, sentence-length answer scores full credit. Comma-separated lists (flows, priorities) are scored by how many distinct items you list.
How many key flows and design priorities should I list?
The score rewards at least 3 key flows and at least 2 ranked design priorities as a practical minimum for a brief a designer can act on — fewer than that usually means the scope or trade-offs are not yet clear enough to hand off.
Can I use the assembled brief as-is with an agency or freelancer?
Treat it as a strong starting draft. Review it with the designer or agency you are working with and adjust it to match their intake format — some will want more detail in specific sections than others.
Is this the same as a full product requirements document?
No — a UX brief is narrower, focused on the information a designer needs to start (users, goals, flows, constraints, priorities). A full PRD typically also covers technical requirements, timelines, and business logic beyond design scope.
How We Compare
| Feature | MVPHub | Notion | UXPressia |
|---|---|---|---|
| Structured brief assembled from your own inputs | Included | Limited | Not included |
| Brief-completeness scoring | Included | Not included | Not included |
| Free-form document editing and collaboration | Not included | Included | Limited |
| Customer journey and persona mapping canvases | Not included | Not included | Included |
Notion is a general-purpose workspace where teams write and share briefs manually with no built-in completeness check. UXPressia focuses on persona and journey-map canvases rather than a project-kickoff brief. UX Brief AI is narrower and faster: it turns a few structured inputs directly into an organized brief with a score showing what still needs detail.
