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

  1. 01

    Cut the account system entirely — the product is the chat, the chat is the homepage.

  2. 02

    Added role-tailored guidance: a researcher and a content designer asking the same question need different answers.

  3. 03

    Added a UX interview practice mode that turns the same model into a rehearsal partner.

  4. 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.

Outcomes

  • A free, signup-free streaming chat, a UX interview simulator, and a curated tools directory. Live.
  • Companion product to UCD Services and UCD Coach
  • Practical on-ramp for UCDOps Agent upsell path
