If you can’t AI prototype after this, nothing will help you

Sachin Rekhi (Former Head of Product of LinkedIn Sales Navigator) breaks down the complete AI prototyping system. The 15-skill mastery ladder, live demos, and why Anthropic builds features this way.

Product shaping changes everything - Anthropic builds multiple prototypes for every problem, launches internally, sees what people use, then productionizes winners. This used to only be possible at Apple with massive labs. 2. AI slop is real - Type "create a CRM" and you get generic styling, vanilla features, basic scenarios. Looks magical but you'd never ship it. The challenge is going from slop to production-grade prototypes. 3. The 15-skill mastery ladder - Apprentice level: prompting, editing, design consistency. Journeyman: versioning, debugging, diverging. Master: functional prototyping, product shaping, analytics integration. 4. Design consistency starts with baselining - Take screenshot of your product. Recreate it. Iterate until perfect. Save as template. Now every prototype inherits your design system automatically. 5. Diverging is the secret weapon - Generate 4 design variants instead of 1. Magic Patterns has this built in. Or use multiple tools to get 8 options. Evaluate alternatives like designers do. 6. Functional prototypes unlock real validation - Integrate OpenAI API for actual responses. Add PostHog for session recordings and heatmaps. Build surveys. Track clicks. Test with real data, not mockups. 7. The tools face-off: which to actually use - Bolt for speed. V0 for beautiful UIs. Replit for full-stack. Magic Patterns for product teams with diverging. Reforge Build for context integration. Cursor for technical PMs. 8. The $5/month unlimited execution hack - Host n8n on Hostinger instead of paying per execution. Get unlimited runs. Build workflow that backs up to Google Drive for version history. 9. PMs can build what used to require engineering - Calendar integration. Email agents. Analytics dashboards. Multi-model comparison. Survey collection. All from prompts. No code required. 10. Traditional workflows beat agents for production - Workflows save tokens, run faster, and are more reliable. Use agents only when tasks need real decision-making. For known processes, use workflows. ---- 👨‍💻 Where to find Sachin Rekhi: LinkedIn: https://www.linkedin.com/in/sachinrekhi/ Newsletter: https://www.sachinrekhi.com/ Reforge AI Prototyping Course: https://reforge.com/Aakash 👨‍💻 Where to find Aakash: Twitter: https://www.x.com/aakashg0 LinkedIn: https://www.linkedin.com/in/aagupta/ Newsletter: https://www.news.aakashg.com #aiprototyping #aipm ---- 🧠 About Product Growth: The world's largest podcast focused solely on product + growth, with over 200K+ listeners. 🔔 Subscribe and turn on notifications to get more videos like this.

CHAPTERS

  1. Why most AI prototypes feel like “slop” (and why that’s fixable)

    Aakash introduces Sachin Rekhi and the central objection he hears: AI prototypes look impressive from a simple prompt, yet still aren’t shippable. Sachin frames the episode as a path from generic one-shot outputs to high-craft prototypes that can actually inform real product decisions.

  2. Anthropic’s “prototype-first” roadmap: prioritizing problem–solution pairs

    Sachin contrasts the standard roadmap flow (prioritize problems, then design solutions) with Anthropic’s approach: prototype multiple solutions first, dogfood internally, and only then decide what to productionize. The key shift is prioritizing validated problem–solution pairs rather than abstract problems.

  3. Product shaping: making Apple-level prototyping feasible for everyone

    Sachin introduces “product shaping” as the discipline of prototyping multiple solutions, testing with customers, and deciding what to build. He explains how only elite companies historically could afford extensive prototyping, but AI makes it cheap enough for most teams to adopt.

  4. Diagnosing “AI slop”: generic design, no differentiation, shallow scenarios

    Using a CRM example, Sachin explains why AI-generated apps often fail the bar for real products. The outputs are typically visually generic, undifferentiated versus incumbents, and don’t reflect true customer workflows—yet the underlying tools can still produce great results with the right skills.

  5. The AI Prototyping Mastery Ladder: 15 skills from apprentice to master

    Sachin lays out a structured ladder for learning AI prototyping as a craft. Apprentice skills include prompting, editing, and design consistency; Journeyman adds versioning/debugging, divergence, and validation; Master includes functional prototypes and product shaping workflows.

  6. Design consistency via baselining: recreate your product, then refine it

    Sachin demonstrates baselining in Bolt by recreating a screenshot of his product NoChoy, then iteratively editing details until it matches the real UI. The goal is a reusable template so future prototypes inherit the product’s look and feel automatically.

  7. Exploration prompts on top of a baseline: prototyping “Ask AI” in-context

    With the NoChoy baseline established, Sachin uses an “explore style” prompt to prototype an Ask AI feature with multiple entry points. Because the prototype is built on the baseline, the new feature looks native and quickly reaches meaningful UX interaction decisions.

  8. Diverging: generate multiple design directions (Magic Patterns + Bolt)

    Sachin shows why divergence is a “secret weapon”: AI should produce many alternatives, not a single mock. He demos Magic Patterns’ built-in divergence to prototype “News in Your Network” on LinkedIn, then repeats the approach in Bolt to show tool-to-tool variation.

  9. From prototype to functional app: deploying and wiring real LLM calls

    Sachin levels up the Ask AI prototype into a deployed, functional experience: real note content, real prompts, and responses via OpenAI API, plus a model selector for comparison. He explains the practical workflow of adding API keys and securing secrets in modern prototyping tools.

  10. Customer validation at scale: in-prototype surveys + analytics + session replay

    Sachin demonstrates how functional prototypes enable scaled feedback loops beyond 1:1 interviews. He embeds an in-app survey, integrates PostHog for analytics, instruments specific events, and uses heatmaps/session replays to identify friction and simplify the UI.

  11. PM vs designer vs collaborative prototyping—and why prototypes are for discovery

    They discuss who should prototype: PM-led, design-led, or collaborative, each with tradeoffs. Sachin emphasizes prototypes should primarily support discovery and validation, not replace engineering delivery—since prototype code is often not production-grade.

  12. Workflows vs agents (and why PRDs aren’t dead): strategy still matters

    Sachin addresses the idea that prototypes replace PRDs, arguing prototypes capture UX/functional requirements but not strategic rationale. They outline what still must be documented: differentiation, acquisition/monetization logic, hypotheses, metrics, and open questions—even in an AI-first workflow.

  13. AI prototyping tools face-off: categories, tradeoffs, and what to choose

    Sachin maps the tooling landscape into three buckets: AI app builders, purpose-built prototyping tools for product teams, and engineering AI coding tools. He shares practical selection advice—start with lowest-friction access in your org—then offers opinionated picks depending on needs and technical comfort.
