Wu recalls moving from specialist quantitative tools toward a multi-perspective research workstation. Stars measure attention rather than completion, live performance or verified returns.
Beginner entry page for Will (Xiaohongshu UX job search blogger)'s "AI-Assisted Design" materials. Distills content exclusive to the Let's Start section: ① 6 must-read usage tips before viewing the materials (the product only serves portfolios/interviews, generate AI images in English first then switch to Chinese, download Prompts instead of opening them directly, which parts of the four modules to read, choose Claude between the two tools); ② 5 core capability pillars of the full material set (portfolio narrative / detailed content generation / Vibe Coding / AI capability system / Agent+Skill+MCP) + 3 ready-made combination recipes (end-to-end portfolio from 0 to 1 / quick experience validation); ③ The resume-tailoring skill that comes even earlier than PitchPro (one tailored resume per job posting). Bot usage mindsets, interview question banks, and creative project explanation prompts are all fully overlapping, and point to [[ai-tools-bot-interview]] without rewriting. Targeted at non-technical PMs, with emphasis on Why and onboarding routes.
Distilled from the Tools section of Will (a Xiaohongshu UX job search blogger). Three reusable assets: ① Transferable principles for writing portfolio copy/interview scripts with custom GPTs like PitchPro — how to feed context (screenshots + JD + goals), how to drill down into details layer by layer from the big framework, how to use a notepad to save content to avoid full rewrites, how to reverse-engineer data and solutions from UI screenshots, and the most taboo vague instructions; ② 60+ common UX/design interview questions grouped into 8 categories (opening/project background/value metrics/design approach/results/retrospective/cognitive methodology/management) + how to answer each category and the interviewer's real intent; ③ 10 sets of creative narrative prompts to tell projects as stories (documentary/user one-take/suspense/battle/dual-timeline/failure reversal/flashback, etc.). The interview questions complement the presentation templates/STAR method in google-ux-portfolio-career — that piece covers structure, while this one provides the question bank and scripts. Targeted at non-technical PMs, with emphasis on Why and reusable templates.
An "AI-empowered UX workflow path" that strings the full process from "problem discovery to delivery and presentation" into a reusable thinking framework. The main thread runs A-Discover & Research → B-Define & Insight → C-Ideate → D-Experience Design → (E-Validate) → F-Deliver; for each phase, it first lays out "what to do" and then matches it with "how to do it with AI". This article is the entry/table of contents page for the will-ai-note series: it explains the core mindset of the full workflow (why phases are divided this way, what role AI plays in each phase), and provides navigation to each phase's wiki + tool-focused wiki pages, as well as its relationship to the google-ux craft series on "how to do UX" — this series is about "doing UX with AI".
