ZCHUT-AI

I designed and tested a prototype that turns an Israeli benefit letter into one plain-language next step, and says when the AI is unsure.

About the project
00The problem

People can qualify for support and still never claim it. In three Israeli benefit programs, more than half of those eligible did not.

01Explain the letter before asking for action

Scanning a letter and asking by voice converge on one interpretation layer. The system explains what the document means before it asks for a decision, and ends in either a specific action or a clear reason nothing is needed.

Guided flow

Known rules and deadlines

  1. Focused question
  2. Structured check
  3. Clear action
02

AI interpretation

Letters, voice and open questions

  1. Natural input
  2. Interpretation
  3. Clarify or escalate
Every answer carries

An official source, a confidence state, or a way to continue with an adviser.

    Says what it sees

    The scanner names the letter before the photo is taken.

  2. 02

    A way around the camera

    A photo from the gallery works too.

Or ask, transcript confirmed first
02Every answer says how sure it is

A confidence gate decides how the answer is framed. When it escalates, the system says why and passes the conversation to an adviser, so the user does not repeat the story. The cost: more interface states, and a dependency on adviser tools.

03What four sessions changed

I ran four moderated sessions with Wizard-of-Oz responses. Participants used the AI to work out what to ask, not as a final authority on money, so the source, the verification step and the handoff stay visible in every response.

    Count first

    The headline says how many items need action.

  2. 02

    "!" means act

    The warning badge appears only where action is required.

  3. 03

    Specific action

    The button names the task: sign the form.

  4. 04

    AI on offer

    Help sits beside the work, not in front of it.

"!" now means action is required. When nothing is needed, the state is neutral.

04How I used AI

I used AI to scaffold prototype states and edge cases. I set the product rules, the research questions and the validation boundary.

What this does not prove

Four qualitative sessions are not statistically representative. Wizard-of-Oz responses tested comprehension and trust, not model or legal accuracy. Without a baseline, I can explain the changes but not quantify a gain in comprehension.
