Free streaming AI chat for user-centred design.

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. 1

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

2. 2

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

3. 3

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

4. 4

   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.

Interaction.

• No signup is the feature

  It's stated in the meta description, not buried. The most common objection is answered before it forms.

• 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.

• Role tailoring instead of a persona picker

  Adapting to the phrasing of the question rather than making people classify themselves up front.

• 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.
