A random mix from the whole library. Shuffle for a new set.
One poster set up a single AI agent on WhatsApp for their three-person family, with each member using it for different tasks and the agent surfacing relevant information proactively before being asked. The whole setup runs on one $200/month AI subscription.
The app came out of his own frustrations managing two kids with his wife. Tiny Tummies is a UK baby weaning log that also tracks food, medication and sickness, and it has no subscription. It took about a month to build and three weeks to get approved, and a series of updates and an in app purchase are going through approval now. He built it on the AI Pro plan.
Eric's daughter and her friend needed lodging for a music festival in Europe during her study abroad. His Dot, Jarvis, priced four places and annotated each with whether the walk back from the shuttle has streetlights after 10 p.m. When a provider replied in French, Jarvis read it, updated the comparison and said what changed: one rental ruled out, another cheaper but with a longer, uphill, unlit walk home. Eric finished the checkout himself.
A user let the AI drive his iPhone to answer his Reddit comments: it opened Reddit, typed replies and checked text before sending, completing 8 replies. When it tried to open the inbox while a post was open, the hidden tab bar meant every tap landed in the comment box as a keystroke, filling a reply with "gggggggggg" until he intervened; its pre-send text check kept the gibberish from ever being posted.
One-shot a SketchUp plugin in Ruby, a language he does not know, for his wife, enabling easy 2D export from SketchUp.
Eleanor Konik writes that she hates requesting books through the county library website, so she told the AI to find books about chess aimed at a bright 6-year-old; the AI picked titles and requested them using her library account. A few days later the county emailed that the books were available, and she picked them up (her post also shares an AI invite code).
The AI monitored swimming lesson availability and automatically booked a suitable lesson for his son when one opened up.
He built a tool that reads the emails from his kid school and activities, swimming, music classes and scouts. It adds everything to their shared calendar, sends a WhatsApp message the day before reminding them what to pack in his school bag, and tells them what is on the lunch menu so they do not cook the same thing for dinner. He says the morning scramble is gone and the head space is back.
Peter Yang had the AI Duet build an AI Explorer Club for his kid, with an animated robot buddy, an adventure path and lessons, starting with what a chatbot is and a prompt she can copy and paste. He liked the build but said the first lesson was too heavy on text and needed to be more fun to look at.
The AI whipped up an animated demo to teach his 5 year old why the sky is not black, a better explanation than existing ones he found.
A fellow parent pointed him to the Tilt Parenting podcast, which has more than 500 episodes. He told his second brain in an AI app to search the archive for episodes relevant to his situation, and it picked 29 episodes, saved their transcripts, and wrote him a brief on what each one could teach him.
A new dad on paternity leave built a full baby tracker with AI in a week, then opened it to other parents as a cheaper SaaS after finding existing trackers obscenely priced. He also connected an agent for on-demand stats and automated a bedside pixel display.
The user built EVA, a family assistant on the AI, which finds what matters in school email, tracks deadlines, updates the family calendar, and answers questions about what is coming up.
A mom of four school age kids started using AI last week and it already watches her school email, the grades site, Google Classroom and the ClassDojo app. It adds events and tests to the family calendar, sends a weekly report on missing assignments, reminded her about a field trip permission slip today, and drafts the email when a kid is out sick.
Rosey adds calendar events and reads credit card balances for budgeting.
In the same roundup, Jason Zhang listed a bonus feature: sending messages to friends via connected Messenger and Instagram accounts.
He built an app that lets their nanny track her worked hours in it, so the family does not have to keep track so closely. The app holds their contract details with her, including the exceptions for vacation and sick days, and gives a total at the end of the week for payment reconciliation. It is one of several small apps he has built for family life.
Simmons asked László to check in with his father once a week about the business sale and report back, judging his father more likely to talk it through with an AI checking in than to raise it with his son. The article records the arrangement being set up, not its later results.
Given access to the user's XP Tickets account, the AI locked in two orchestra seats for a concert that night at $117, and is negotiating with a season ticket holder over Warriors vs Mavericks tickets for his brother's birthday.
He had the AI put together a big brief on summer day camps that take 5 year olds within a 15 minute drive in rush hour of his zip code, with one Spanish immersion camp. He read the options, checked drive times and the camp sites himself, and says the three camps they went with were great and close.
Every idea is a real post from someone who tried it, summarized in our words, with a link to the original. App names are swapped for plain words.
