In today’s pre-Thanksgiving episode, I walk you through how I vibe coded my very own “Thanksgiving party hub” using Lovable—and how I transformed it from AI-generated slop into something warm, personal, and genuinely useful. I show you exactly how I upleveled the typography, visuals, and structure using Google Fonts and Midjourney style references, and then I share one of my favorite real-life AI hacks: how to turn any messy online recipe into a clean, step-by-step, kid-friendly version that’s actually usable while you’re cooking. This is a cozy, practical walkthrough of my real design process—the little tricks I use to make AI-built apps feel handcrafted instead of generic.

What you’ll learn:

  1. How to build a fully functional Thanksgiving party hub in Lovable—guests, dishes, recipes, and photos

  2. How I uplevel AI-generated designs using Google Fonts and Tailwind

  3. How to use Midjourney style references to create custom images that match your aesthetic

  4. How to add custom features to vibe-coded apps, like dietary preferences and allergen tags

  5. How to iterate on layouts inside Lovable using screenshots and small, targeted prompts

  6. How I use ChatGPT to restructure recipes so the measurements are embedded directly in each step

  7. How to make recipes kid-friendly and easier to follow using a simple formatting prompt

Enjoy!


For the home

  1. Handcrafted Modern maple donut bowl: My wife got us this, and I was like “wtf is it?” But then I realized how much a beautiful wood piece adds to your space. The artist makes lots of other great stuff, too.

  2. Coyuchi 100% organic cotton sheets: Pricey, but oh so nice. You spend so many hours in your sheets, imho it makes sense to splurge here.

  3. Deadline candle: “Transforms your most dreaded moments into sacred ritual.”

  4. Matic: Wirecutter, Wired, Gizmodo, The Verge, and ZDNet have all reviewed it and said it’s the best smart vacuum ever made. I agree. We use ours constantly. They are raising prices on December 2 (from $1,095 to $1,245—tariffs 🫠), so ordering before then will save you $150. They also offered me a deal to share with this community: use this link to get a free 6-to-9-month supply of replacement HEPA bags. Their team sent me a unit to try out when they were just getting started, and I loved it so much I’ve been telling everyone about it.

  1. Living Tea seasonal tea club: A friend got this for me, and it’s so nice. They include background on each tea, how to best steep them, and all kinds of extras that make the experience feel special. These stainless-steel infusers are really handy (especially if you’re wary of tea bags these days). We also love Leaves and Flowers and Rishi teas.

  2. Koshi chimes: The sound of these is unique and delightful. “Simply move the chime gently holding it by its cord to produce a crystalline, relaxing sound that mesmerizes and calms.”

  1. Plant-based desk lamp: You may have noticed one of these in my podcast background. We bought it at the West Coast Craft fair in SF, but they also sell them at SFMOMA. I don’t recommend the ones with legs, though, as they tend to come off. These are also cute. As are these classic Noguchi lamps.

  2. Angels Horn vinyl record player: Includes built-in speakers (and Bluetooth!), so it’s a really easy, versatile, and affordable way to enjoy records. We’ve had this for years and love it.

  3. Graf Lantz Bierfilzl merino wool round coasters: I can’t get enough of these around the house. Lots of color options, and the square ones are nice too.

  4. Vera salt: Microplastic-free salt. After learning that I was half-man, half-plastic and also that sea salt is one of the most microplastic-laden foods one can consume (thanks, Huberman 🥴), we discovered this product (through Superpower marketplace), and it’s now our go-to salt. Pretty, healthy, and yummy. Pairs well with this plastic-free Klean Kanteen water bottle (which is not as fun as other bottles but easy to clean).

For parents and kids

  1. Charts for Babies by Michelle Rial: MY WIFE HAS A NEW BOOK COMING OUT. I know I’m biased, but it’s genius. It’s also cute as hell, will warm your heart, and will incept your kids into liking STEM. It’s coming out in April, and you can pre-order it here. If you haven’t seen her first book, that one makes a great gift too (for adults).

  1. Emerging Artist beanie for babies: We gifted this to our nephew when he was younger, and it’s never not funny.

  1. Kids’ guitar or piano: They come with guides to help you learn, and they are really high-quality. My wife and I even practice on it while we’re playing with our son because we’re both learning piano.

  1. Yoto mini player: A neat screen-free audio player for kids. Our son loves his so much. He rotates between the Beatles, Raffi, Queen, and Spanish cards while he walks around dancing, listening to it (rather than staring at a screen). How can you not love that? Sir Paul McCartney and Chan Zuckerberg Ventures are investors, to encourage more screen-free entertainment options for kids. Many people love the Tonies as an alternative.

  1. Personalized ring (or necklace): For your BFF, mom, lover, or just get it for yourself. As a fun twist, make it the joke name you call your kid/pet.

  1. Personalized pennant or blanket: Is there anything kids/parents/humans love more than their name on stuff?

  1. Coyuchi handstitched organic toddler blanket: Nontoxic naps for your little one.

  2. Kids’ Adirondack chair: Extra-cute if you place it near your adult-sized chair on the porch.

  1. Organic floppy brown teddy bear: This teddy bear is relatively expensive, but it’s a rare non-polyester option for something your kid will be snuggling all night. It’s made in Germany from certified organic cotton and pure organic wool. They have other animals too.

  1. John Klassen prints: There are also originals, but most are sold out. More prints here. IYKYK 🔺

For gadget lovers

  1. ModRetro Chromatic: A modern remake of the original Game Boy by Palmer Luckey (founder of Anduril and Oculus). It feels great, plays great, and makes a unique gift for gamer friends.

  1. Peak Design tech pouch: They also make a larger version, and their toiletry bag is great.

  1. Aranet CO2 monitor: Did you know high CO2 impairs your cognition? Research shows that brain function decreases by 15% when CO2 levels are over 1,000 ppm, and by over 50% above 1,400 ppm. Freaky shit. I’ve got one of these in my office and open a window anytime it gets into the yellow zone.

  1. Belkin MagSafe 3-in-1 charger: I saw these at a hotel once, immediately got it, and love it. Better than any other nightstand charger I’ve tried.

  2. Herschel tech backpack: This has been my go-to bag for years.

  3. Sony WH-1000XM5 noise-canceling wireless headphones: These have become my workhorse headphones. Grab this cute stand if you use headphones at your desk. My wife prefers the Bose QuietComfort because, as the name suggests, they are comfy.

  4. iPhone case with built-in stand: I learned about this from Kevin Rose’s newsletter. There’s also an Anker version, but I like this one better.

  5. Hooga amber book light: I originally got it to change the baby’s diaper during the night while keeping the lights dim and super warm. Now use it nightly while reading in bed. Lasts forever, charges easily, and has multiple brightness settings.

  6. Amazon Kindle Colorsoft: Did you know they make Kindles in color? Thanks for the tip, Laura Fingal-Surma.

  7. AirPods: For all your friends who have “AirPods #1,” “AirPods #2,” . . . “AirPods #5” in their Bluetooth devices list.

For your stressed founder friend or family member

  1. Function Health or Superpower membership: Make sure they aren’t pushing themselves too far.

  2. Spirit Rock gift certificate: I did a 10-day silent retreat there a number of years back, and it was life-changing. Check their upcoming retreats here.

  3. The Anti-Anxiety Notebook: “Utilizing Cognitive Behavioral Therapy, a rigorously-tested and widely-used treatment, you’ll develop the skills to identify, challenge, and change unhelpful thought patterns so you can feel better.”

  4. Japanese Hot Spring Minerals bath salts: 🧘🧘🧘

  5. Leaves and Flowers Sleep Tea: 💤💤💤

  6. Rice wax Japanese candles: 🕯️🕯️🕯️

  7. Candle holder: Goes well with beeswax tea lights, and creates a really nice light effect.

  8. Runnin’ Down a Dream: How to Thrive in a Career You Actually Love by Bill Gurley: I haven’t read this yet, but I’m 100% sure it’ll change many people’s lives, considering the impact his talk on the same subject has had on people I know.

  9. Squishy stress ball set: I’ve got fidgety hands, so I often need something to play with. You may see me holding these during my podcast chats sometimes. “Free from BPAs, phthalates, and latex.”

  10. “Things will work out” keychain: A comforting reminder to have around.

For the PM who just cashed out their OpenAI stock

  1. Donate to GiveDirectly, St. Jude Research Hospital, SF-Marin Food Bank, or your favorite charity.

  2. Evil eye charm or stoneware

  3. 100-pound Parmesan wheel: “Crafted by hand from the milk of cows grazing high in the alpine meadows of Benedello di Pavullo, these monumental Parmesan wheels are aged by Giorgio Cravero, whose family has been perfecting the art of affineurship in Bra, Italy, since 1855. Simply put—the best Parmigiano Reggiano that exists.”

This week on How I AI: How Emmy Award–winning filmmakers use AI to automate the tedious parts of documentaries

2025-11-18 00:03:26

Hey friends 👋,

Here’s a weekly recap of new podcast episodes across Lenny’s Podcast Network:


Every Monday, host Claire Vo shares a 30- to 45-minute episode with a new guest demoing a practical, impactful way they’ve learned to use AI in their work or life. No pontificating—just specific and actionable advice.

“Nobody wanted to do this work”: How Emmy Award–winning filmmakers use AI to automate the tedious parts of documentaries

Brought to you by:
Brex—The intelligent finance platform built for founders

Guest: Tim McAleer, producer for Ken Burns’s Florentine Films

Biggest takeaways:

  1. Custom AI tools don’t need a large market to be valuable. Tim built hyper-specific tools for his team’s unique workflows, noting that while the “total addressable market” might be tiny, the impact on their production process has been enormous.

  2. Different AI models excel at different tasks. Tim uses Claude for coding, OpenAI for image analysis, Whisper for audio transcription, and CLIP for embeddings—demonstrating how a thoughtful multi-model approach delivers better results than relying on a single system.

  3. Embedded metadata is the secret weapon. Rather than just generating descriptions, Tim’s system extracts existing metadata from archival sources (like Library of Congress annotations) and uses that as ground truth to guide the AI, preventing hallucinations and ensuring accuracy.

Brex—The intelligent finance platform built for founders


Tim McAleer is a producer at Ken Burns’s Florentine Films who is responsible for the technology and processes that power their documentary production. Rather than using AI to generate creative content, Tim has built custom AI-powered tools that automate the most tedious parts of documentary filmmaking: organizing and extracting metadata from tens of thousands of archival images, videos, and audio files. In this episode, Tim demonstrates how he’s transformed post-production workflows using AI to make vast archives of historical material actually usable and searchable.

What you’ll learn:

  1. How Tim built an AI system that automatically extracts and embeds metadata into archival images and footage

  2. The custom iOS app he created that transforms chaotic archival research into structured, searchable data

  3. How AI-powered OCR is making previously illegible historical documents accessible

  4. Why Tim uses different AI models for different tasks (Claude for coding, OpenAI for images, Whisper for audio)

  5. How vector embeddings enable semantic search across massive documentary archives

  6. A practical approach to building custom AI tools that solve specific workflow problems

  7. Why AI is most valuable for automating tedious tasks rather than replacing creative work

The Godmother of AI on jobs, robots & why world models are next | Dr. Fei-Fei Li

2025-11-16 22:03:30

Dr. Fei-Fei Li is known as the “godmother of AI.” She’s been at the center of AI’s biggest breakthroughs for over two decades. She spearheaded ImageNet, the dataset that sparked the deep-learning revolution we’re living right now, served as Google Cloud’s Chief AI Scientist, directed Stanford’s Artificial Intelligence Lab, and co-founded Stanford’s Institute for Human-Centered AI. In this conversation, Fei-Fei shares the rarely told history of how we got here—including the wild fact that just nine years ago, calling yourself an AI company was basically a death sentence.

We discuss:

  1. How ImageNet helped spark the AI explosion we’re living through [09:37]

  2. Why world models and spatial intelligence represent the next frontier in AI, beyond large language models [23:53]

  3. Why Fei-Fei believes AI won’t replace humans but will require us to take responsibility for ourselves [05:31]

  4. The surprising applications of Marble, from movie production to psychological research [48:02]

  5. Why robotics faces unique challenges compared with language models and what’s needed to overcome them [40:45]

  6. How to participate in AI regardless of your role [01:14:24]
