UCD Chat
Free streaming AI chat for user-centred design.
Overview
Free streaming AI chat for UX and service design. No signup, role-tailored answers, plus a UX interview simulator.
The problem
Someone mid-workshop wants to know the difference between a service blueprint and a journey map. The gap between that question and an answer should be one box, not an email verification. Every friction point you add halves the audience for a question that small.
0→1
- 01
Cut the account system entirely — the product is the chat, the chat is the homepage.
- 02
Added role-tailored guidance: a researcher and a content designer asking the same question need different answers.
- 03
Added a UX interview practice mode that turns the same model into a rehearsal partner.
- 04
Put monetisation on a curated tools page, so it never touches the product surface.
Under the hood
Server-side streaming with the model layer never exposed to the client. Prompt architecture separates domain grounding from tone, so the practice mode swaps one and keeps the other.
Features & interaction design
- 01
No signup is the feature
It's stated in the meta description, not buried. The most common objection is answered before it forms.
- 02
Streaming is a UX decision, not a technical one
First token beats total latency for perceived speed. The interface is built around getting something on screen fast.
- 03
Role tailoring instead of a persona picker
Adapting to the phrasing of the question rather than making people classify themselves up front.
- 04
Practice mode reuses the surface
/practice is the same chat with a different contract — an interview simulator, not an answer engine. New job, no new interface to learn.
