Lenny's Newsletter · Product & Work
TIER 4 2025-07-08
Everyone’s talking about [vibe coding](https://www.lennysnewsletter.com/i/153296003/vibe-coding), and how important it is to get your hands dirty by using the latest AI tools. But what are people building? And are these products useful, like for real? The answer is a resounding yes. I asked on [X](https://x.com/lennysan/status/1938252382447845524), [LinkedIn](https://www.linkedin.com/posts/lennyrachitsky_whats-a-producttool-you-vibe-coded-that-activity-7344093906420056064-PG_J?rcm=ACoAAABGvmoB4S920iEQfSFO_P91nw2wPqfPoic), and my subscriber Slack community: **What’s a product or tool you vibe coded that you actually use regularly in your work or life? And what tool/platform did you use to build it?** The response was overwhelming: Within 24 hours, I got over 1,000 enthusiastic replies, ranging from a buzzer app that automatically answers apartment deliveries, to a hyper-personalized greeting card generator, to a workplace accomplishments tracker, to a daily newsletter to help you learn a new language, to the perfect playlist curator for your next festival road trip. Your stories opened up my mind to what’s possible, and even inspired me to vibe code a few new tools for myself, including this sweet [YouTube thumbnail preview tool](https://project-youtube-podcast-title-and-thumbnail-previewer-348.magicpatterns.app), [a tool to help me craft tweets for my podcast clips](https://tweet-punch-perfect-posts.lovable.app/), and the beginnings of a [tracker of the most mentioned books by podcast guests](https://v0-lenny-s-book-mentions.vercel.app/) (data isn’t real yet). To nudge you forward on your own vibe-coding journey, I’ve pulled together over 50 of my favorite examples from everything you shared. As you’re reading through this list and wondering what to do, try opening up one of the AI tools (or a few at a time) and **simply describe what you want in plain English**, as if you were talking to a remote engineer. Then, iterate by describing what you want to change about what you see, as if you’re speaking with a remote engineer. You’ll be surprised by how far you’ll get. #### **Some high-level takeaways from the stories you shared:** - **Cursor**, **Claude Code**, **Replit**, and **Lovable** were your favorite vibe-coding tools, followed by v0, Bolt, and ChatGPT. Honorable mentions to Gemini, n8n, Zapier Agent, Warp, and Windsurf. - **Almost no examples are alike.** Everyone is solving their own hyper-specific problem (e.g. group drafting app for your multi-sports fantasy league), or exploring a random idea they (or their kids) suggested (e.g. a cats and sushi browser-based video game). Welcome to the era of n-of-1 personalized software. - **You’re creating a lot of Chrome extensions.** This makes sense—we spend most of our time in the browser. - **Even though you’re solving your own problem, many of the products end up being used by tens/hundreds/thousands of other people.** Excellent sign! - **Women are vibe-coding like crazy.** The male-female ratio in the responses is more balanced than in most tech conversations. Another excellent sign! Thank you to all 1,000+ of you who shared your stories 🙏  ## **Health, wellness, and style** ### Carb counter, by [Morgan Brown](https://www.linkedin.com/in/morganb/) using Replit > “I built CarbScanto help manage my son’s diabetes and blood glucose levels with faster carb counting.

Weather apps had too much clutter for simple daily clothing decisions.” [[Check it out](https://howmanylayersidag.se/)]  ### A “stupidly specific” workout app, by [Faraz Khan](https://x.com/farazKhan404) using v0 and Claude Code > “I built a stupidly specific workout app for myself. It’s pretty gross and not for anyone else, but I love it. I was chatting with Claude about switching up my program, and I was about to ask it to format it into a table when I realized, ‘Wait, I’m in Claude and it can make Artifacts.’ Finally I ended up dumping the code into v0 to get it deployed.”  ### Personalized meal plans based on what’s in your fridge, by [Nick Markman](https://www.linkedin.com/in/nickmarkman/) using Lovable and Cursor > “I built a web app using Lovable, Supabase, and Cursor where you can upload photos of your fridge/pantry/receipts (or use voice) to detect ingredients you have at home, save to ‘inventory,’ and generate recipes using AI. > > It factors in the user’s set dietary preferences and input of how strict/flexible recipes should be with using what you have in inventory vs. things you need to buy. It also auto-generates a shopping list for ingredients you need to buy for selected recipes.” [[Check it out](https://mealmuse.ai/)]  ### Find out what’s blocking your flow, by [Su](https://x.com/su_dreams) using Bolt > “Flowbound is an app that gives me games/exercises to do when I find myself procrastinating on something (which is often).” [[Check it out](https://www.flowbound.app/)]  ### Pickleball games tracker, by [Jacob Jolibois](https://www.linkedin.com/in/jolibois/) using Replit > “I (and users from all across the U.S.) use Paddles.ai to track and analyze my pickleball matches.

And all my friends have used it already. > > I also built a logo animator with Bolt that uses the GSAP library to animate our logo in cool ways, for different onboarding experiences.” [[Check it out](https://timelessmemories.me/)]  ### Baby care tracking, by [Javier Evelyn](https://x.com/hah_vee_AIR) using Lovable > “I’m a new dad, and while waiting for the little one to arrive, I started tinkering around with Lovable. I built My Baby Logger over two weekends. Tracks feedings, sleep, diapers, and meds. It’s been helpful for us.” [[Check it out](https://mybabylogger.com)]  ### A chore app for kids, by [Ben Ogren](https://x.com/benogren) using v0 and Claude Code > “I built a chores app for my kids. It’s my first iOS app! I started with v0 but quickly moved off it and started using Claude to help me through areas where I got stuck.” [[Check it out](https://www.chores-ai.com/)]  ### A bedtime storytelling app, by [Harshitha P.](https://www.linkedin.com/in/harshitha-p-991776149/) using Bolt > “I built this for parents, and now I use it every night. It’s a bedtime storytelling ritual that turns your daily emotions into personalized stories for your child. You reflect, drop a ‘pebble’ or plant a ‘story seed,’ and the app creates a calming, age-appropriate story shaped by what’s on your heart. I built it solo in Bolt + Supabase**,** and what started as a side project became my nightly parenting ritual.” [[Check it out](https://stories-of-life.vercel.app/)]  ### Personalized greeting card generator, by [Bob Sheth](https://x.com/bobsheth) using Cursor, Windsurf, and Claude Code > “I vibe coded an AI greeting card generator, and send everyone I know these hyper-personalised cards.” [[Check it out](https://jenicards.com/cards)]  ## **Work productivity** ### Meeting prep automation, by [Marissa Goldberg](https://x.com/mar15sa) using Zapier Agent > “It checks my calendar each morning, identifies who I’m meeting with, and compiles everything I need to show up prepared.” [[Here’s how to build it](https://ideakitchen.substack.com/p/ai-recipe-create-your-own-meeting)]  ### A standup order randomizer, by [Rob Balderstone](https://www.linkedin.com/in/robbalderstone/) using Lovable > “I use this daily at work.” [[Check it out](https://standup-buddy.lovable.app/)]  ### Chrome extension to share your availability, by [Olena Vozna](https://www.linkedin.com/in/alionavozna/) using Replit > “A Chrome extension that adds my availability to emails in natural, human-style language. It also analyzes suggested times from others, picks the best one, and books the meeting. İt learns my meeting habits to recommend the most suitable slots. > > Then, a Slack app for team scheduling that uses the same core algorithm. It learns everyone’s preferences and finds the best time when I type something like *Schedule a 45-minute call with Mary and Jane this week.* Or *Schedule a focus time for me today. I need 2 hours.* Both were built with Replit.”  ### A time tracking app, by [Asif](https://x.com/asifkabeer) using Warp.dev > “I built a time tracking app with Warp.dev. All done in a day.” [[Check it out](https://time.wisdemic.com/)]  ### Inbox focus tool, by [Ari Klein](https://www.linkedin.com/in/kleinari/) using Gemini > “I built a Gmail add-on that doesn’t let my inbox hijack my day or steal my attention. I use it every day. It holds my inbound email and delivers it to my inbox on a schedule I set (e.g. 10 a.m. and 3 p.m.) but still lets important emails through right away if they match certain VIP keywords (e.g. verification code), VIP domains (e.g. my-kid’s-school.org), or VIP email addresses (e.g. wife@gmail.com). Built with Gemini.”  ### Accomplishments tracker to showcase your wins at work, by [Kevin Kirkpatrick](https://www.linkedin.com/in/kevinkandco/) using Lovable > “Built this for myself because I hate updating my resume, and I think other people hate it too. Built it with Lovable and I use it weekly to track what I’ve accomplished.” [[Check it out](https://www.goaccomplishit.com/)]  ## **Personal productivity** ### Automatically answers your apartment buzzer calls, by [Darren Rulofs](https://www.linkedin.com/in/darrenrulofs/) using Bolt and Cursor > “I built Buzzerbee using Bolt and Cursor. It automatically answers your apartment buzzer calls based on the access rules and schedules you set in the app. I’ve been using it daily, and others have been joining as well. Turns out people don’t like missing deliveries!” [[Check it out](https://buzzerbee.app/)]  ### Bill splitter, by [Shashikiran Devadiga](https://www.linkedin.com/in/shashikirandevadiga/) using Lovable > “My one-screen, tip-first bill splitter. Whenever friends float dinner plans, I plug in the menu subtotal, head count, pick the state, and nudge the tip slider. In two seconds, I see each person’s final after-tax share—something Splitwise can’t show until the check arrives. It’s become my quick ‘Can I afford this outing?’ filter and saves the awkward math at the table. And I built it using Lovable dev + Unicorn Studio.” [[Check it out](https://my-bill-split-project.lovable.app)]  ### A personalized restaurant recommendation app for friends, by [Lani Young](https://www.linkedin.com/in/lani-young/) using Replit > “I used Replit to bring to life something I’ve always wanted to build: a restaurant recommendation site for my friends to give them a curated restaurant recommendation based on what they are looking for in a specific meal/experience. It’s a combo of a database, RAG, and natural language chat with an LLM. Right now, it’s only Denver-based, but aiming to fill that gap between Yelp (too much junk/can’t trust the recommendation) and trying to find a new place.” [[Check it out](https://www.curated.now)]  ## **Personal development** ### Conversation intelligence, by [Peter Nixey](https://x.com/peternixey/status/1938537295763636456) using Claude Code > “This lets you paste in the transcript from a call and gives you a breakdown of what you did well and what you can improve on. I just used Claude Code. It’s surprisingly powerful.” [[Check it out](https://claude.ai/public/artifacts/cf207ca7-a35a-42e6-8843-3d5edcccf9f8)]  ### Daily newsletter to help you learn a language, by [Dustin Coates](https://www.linkedin.com/in/dustincoates/) using v0 > “I created a daily newsletter (with an audience of 1) that emails me every day at lunchtime: > > - A story in the language I’m learning, geared toward my beginner level. The story is about something that happened on that day in history, generated by Gemini. > - A list of vocabulary from that day’s story > - A short grammar lesson from that day’s story > > I tried Replit, Bolt, Gemini, and v0, and v0 came out with the best newsletter design. Then I had v0 also create the script for running the email (via Resend) and a script for packaging the code to upload to Lambda.”  ### Talk to an AI about your day, by [Alex Mathew](https://x.com/alxmthew) using Replit > “I built an app that lets you talk to an AI about your day-to-day problems. Used Replit.” [[Check it out](https://talk.berryplush.com/)]  ## **Music** ### Curate the perfect playlist for your next festival road trip, by [Steven Newstead](https://www.linkedin.com/in/steven-newstead-33547414/) using v0 and Cursor > “I made a website to help with artist discovery for UK festivals. I use it to quickly generate playlists. I wouldn’t say it’s widely used beyond a handful of people. But it’s quite decent. I used Cursor and backed by Supabase for Spotify authentication. Currently all running on free tier infrastructure.” [[Check it out](https://www.fyredrill.dev/)]  ### A music production tool to inspire new ideas, by [Scott Korchinski](https://www.linkedin.com/in/scottkorchinski/) using v0 and Cursor > “I made this music production tool the first week we got the Lenny AI bundle, with 90% v0 and 10% Cursor. I think it took three days from idea to shipping. I use it weekly just to get inspired for new musical ideas. Hotjar shows a handful of users per week, too!” [[Check it out](https://splintr.dreamgazeraudio.com/)]  ## **Other/Fun** ### An RPG game, by [Jean Kaddour](https://www.jeankaddour.com/) using Cursor > “I love RPG games and was looking for an online, AI-based RPG game so I can play without friends around. I then vibe coded Rehearsal—a browser game where you have 10 minutes to convince an AI character. For example, to convince a hostage taker to release hostages, or convince a broke flatmate to pay his share of rent. I used Cursor (Sonnet 3.7) + Next.js. I built a first version in a day. Since then, both my g.f. and I are addicted to it and play daily.” [[Check it out](https://rehearsal.so/)]  ### Immigration document manager, by [Shree](https://x.com/sreeenidhi) using v0 > “Immigrants from India and China have a 10- to 20-year journey where you have to file something every couple of years. VisaMonkey keeps all your immigration-related documents in one place so you can find the information you are looking for quickly instead of searching through mountains of documents. It’s also useful to fill out forms.” [[Check it out](https://visamonkey.com)]  ### **Have you vibe coded something that you use regularly?

I’m a designer, and I used Cursor + ChatGPT. The ability to quickly spin up Figma plugins for niche uses is a game changer!” —[Kayt (Campbell) Wilson](https://www.linkedin.com/in/kayt-wilson-4973b350/) 9. “Not a product per se, but I vibe coded our backend systems across Women Defining AI to help us centralize member management—auto sync to Mailchimp and Slack, and help us auto-approve registrations to Luma events using the member list.” —[Helen Lee Kupp](https://www.linkedin.com/in/helenleekupp/) 10. “I built a tool for our agency that reads AI summaries of meetings and creates tasks and puts them on calendars.
