The AI that instantly gets you and cooks up mini-apps

Macaron is a personal AI you'll click with from the very first chat. It remembers your preferences, experiences, and desires far better than a friend, and can instantly cook up personalized mini-apps to make the conversation sweeter.









👋 Hey Product Hunt!
I'm Kaijie, and I've been passionate about building AI products since GPT-2. Previously, I founded @MidReal that I grew to over 3 million users.
🤔 What is Macaron?
Macaron instantly connects with you from the very first chat.
Macaron effortlessly remembers your preferences better than any friend (thanks to reinforcement learning), and cooks up personalized mini-apps in your conversations to help you. Think: fitness trackers, travel planners, reading companions, mini-games — anything you need. And you can share your favorite mini-apps with your friends!
🍪 Why Macaron?
Most AI apps today are about productivity, not people. I wanted to create something that gets to know you and is useful in everyday life. That's why I built Macaron.
I’ve put a lot of love and thought into Macaron, and I’m incredibly excited to share it with you today.
Imagine if you could fill in a form for ChatGPT on a regular basis (e.g. calorie tracker, OOTD picker)? What kind of mini-apps would you create with Macaron?

@kaijiechen Interesting product indeed! :) Since Macaron remembers personal details, how does it handle privacy and data security?

@rohanrecommends
Hi, thanks for the thoughtful question! Macaron uses Personalized Deep Memory: it remembers only key preferences, experiences, and emotions that meaningfully improve support, not everything. We’ve documented this exact topic in our official website.
@kaijiechen Feels like it actually learns me, not just prompts. Can I templatize a mini-app and share it with a public link?
MidReal
@anwarlaksir
Thanks for the question, and glad to hear Macaron feels that way! You can’t share a mini-app publicly just yet, but we’re already working on a sharing feature so friends can use your creations!
@kaijiechen I love what you and your team built, and the video you did, man, what a way to sell your product, it's the first launch video of cofounders I see till the end, and I immediately downloaded the app. Well done, guys.
MidReal
@nico_ramella Hi, thank you so much for the kind words, and that really means a lot to our team. We’re thrilled to hear you’ve already downloaded the app! If you run into any questions or have suggestions while using it, feel free to reach out directly. Can’t wait to hear how your experience goes!
@juno_ So far, it has been amazing. I'm about to create a personal app for expenses that I wanted to do months ago. I will update how that goes here. But the onboarding is SO cool, I will keep it in mind for inspiration ❤️

@kaijiechen lovely and totally agree! we need more personal AI rather than productive AI
@kaijiechen Fitness trackers, travel planners, mini-games, etc. make it easy for people to imagine value.Also Istantly connects from the very first chat” feels warm and relatable.
Congrats on the launch! Trying it out now. Is there a specific type of output that Macaron shines with?
@cholden_lewis Oh yea, it's best at helping you plan or track things, your trip, budget, exercise, meal plan, plants, pets, or anything you desire. It can also create cute mini-games if you like 😆
MidReal
@cholden_lewis Thanks so much, and best of luck with your upcoming launch! Can’t wait to try it out once it’s live.

Fantastic name and design! I'm gonna build a few mini-apps with it and launch them on Product Hunt :D
@justin2025 Hahaha this is a truly brilliant idea, man. I am so looking forward!
MidReal
@justin2025 Hi, thanks so much! The best part for us is seeing how people take Macaron in directions we didn’t even imagine. Looking forward to your mini-apps 😆
@kaijiechen this is so cool. Awesome work, looking forward to checking this out today.
@mcval_osborne Thank you so much! If you found any bug please tell me :)
MidReal
@mcval_osborne Really appreciate it! Always great to have more people join in! We’re looking forward to hearing your thoughts once you’ve tried it.
Wow, the memory function can actually remember my preferences? This is a game-changer. For someone who can't even remember the coffee I ordered, this feels amazing. Is there a limit to the context memory? Is it based on the time dimension or the number of tokens?
@andrew_jameson111 Great questions! Right now the memory is determined by our RL algorithm, and can adjust accordingly. It constantly tries to recall all the things that's important to the conversation right now. So hopefully you never feel it's forgetting things.
@kaijiechen Wow, that's great. It's really an excellent strategy to extract and remember the core points from a lot of context. Looking forward to the follow-up updates.

Discovered your product today! Looks extremely interesting! Congrats @kaijiechen
@viktoriia_yadoshchuk Thank you so much! Chatting with Macaron and see what it can make is indeed interesting 😆
MidReal
@viktoriia_yadoshchuk Hi, thanks so much! Hope you enjoy your first conversation with your Macaron. There’s a lot to discover in Macaron, so have fun exploring, and please let us know which part clicks for you!
I've always wanted an AI that could remember my habits! Can I create little trackers on the fly? I want to use it to record conversations with my girlfriend so I don't forget important holidays. This must be every guy's problem, hahaha. It feels amazing! ✨
