A very big thank you to our awesome PH community! 🙏🏼
Folks - I'm Hoshang, CEO at Airbook. Ever since we started building Airbook, we've always wanted to first launch on Product Hunt. We'd been speaking to other founders and 10/10 founders always mentioned that launching on PH was the best way to get feedback. We've had 4 launches so far and you guys got us to the #1 Product of the Day, twice! It gave us incredible visibility and more importantly, we got some tremendously helpful feedback from the community. It's pretty hard to otherwise get your initial users to get on the product and give it a good try and take the time to share feedback. If it was not this community, we wouldn't have come so far.This week has been incredibly exciting for us. We launched the biggest release of Airbook. Once again, got some super helpful feedback. Every vote, comment, signup means a lot and we as a team go through each and everyone's feedback and make notes on what we can offer next! Your requests become our roadmap and that's how we build and iterate, together! This community is a part of our team and we're all very grateful to have your support!I'd love to take this opportunity to just say a very big Thank you! We will be here to share about what we're going to be building next - show you previews (before launch, before anyone else gets to see it ;) get your feedback, answer your questions, share honest stories about what we learn and unlearn, as we keep building! Stay tuned!Best, Team Airbook

What's your favorite defunct consumer social app? (and what does that say about you?)
@rrhoover 's comment on @kwindla 's "Happy Birthday, Photoshop" thread got me thinking:"I wish Product Hunt was around longer so we had more nerdy, tech archeology to explore."The products that made an impression on us, even if they didn't make it, often inspire the next generation of apps. Also, there's something interesting about a product that you resonated with and you thought should have been huge but didn't quite make it. It's an opportunity for reflection on maybe what was missing or how your values may differ from the world or how that product may have been a glimpse of the future and ahead of its time. I subscribe to the idea that most startup ideas will happen eventually, but timing matters. You need to see into the future, but if you see too far into the future, it may take a while for that to become reality.For me, there are lots of contenders in the consumer social space. I really loved @Clubhouse, especially in the early days of the pandemic. I thought @Airchat had a fascinating interface (twitter...but audio?). I also thought the authenticity and light attention requirements of @BeReal. was compelling. But maybe my favorite more niche product is @Honk by Benji Taylor. Honk was real-time messaging, one-on-one, without a log. You could see people typing in realtime. You could spam emojis, and your swarm of emojis would battle comically with your friend's swarm. It was silly, and beautifully designed, and a valiant effort at breaking through our cultural tendency to regress to boring async chat. There's also something really cool about seeing somebody type in real time. It's like seeing them think! One magic moment is when you start typing and before you can finish the idea, the other person's understood the idea and is responding. It's a funny feeling. Plus their Twitter account was genius. It would often just tweet "Honk" 😂What's your favorite social app that doesn't exist anymore? What did you take away from it? @rrhoover I'm guessing you have too many to count. @bernatfortet @kwindla @gabe

🇪🇺 eu/acc AMA: How can we save Europe?
👋 Hi Product Hunters!I'm here today not to launch a product, but in a way for something much more interesting: to talk about eu/acc 😊For the last decade, I was digital nomading and living in different places all around the world. While the places where I lived abroad, like Asia and America, were getting more ambitious and modern every time I visited them, Europe, and especially Western Europe, started to feel stagnant to me.Of course, that was one of the reasons why I left Europe in the first place. When I said I wanted to be an entrepreneur after graduating university, I was laughed at even by my university classmates who studied business! It was "safer" to get a job for a big corporation and get experience first. Then you could start a business later.And when I finally had my own internet business that was making thousands per month, I remember telling people in Amsterdam, and they'd ask me "when are you going to get a real job?".This was a stark difference from when I was abroad and told people what I did. People were excited, supportive and wanted to learn to do the same thing.Every year that I came back to Europe the culture felt more stagnant, more pessimistic, and more normie.Of course there was great things about Europe for me pulling me back: my parents and brothers live here, and when I ended up in Portugal during COVID, I loved the nature, the clean air and the laid-back coastal surf village life and ended up moving here.And that brought me to an interesting point: seeing where the rest of the world was going, as a European, while seeing Europe slowly getting worse. It became harder and harder to build a startup here. And we started seeing this in losing any lead we had in technology in the last decade. The big tech and AI companies are now all in the US and China, there's very few left in Europe:The insane regulation that the EU brought upon everyone I think directly caused this:VATMOSSGeneral Data Protection Regulation (GDPR)Digital Services Act (DSA)Digital Markets Act (DMA)ePrivacy RegulationThe AI Act...and many moreWhich all had good intentions, but made it very difficult to comply as a small or medium business owner. Sure if you're a billion dollar corporation, you can hire bookkeepers and lawyers to comply. But if you're a one-man or small startup?Last year around April, the data finally started showing what I felt for over decade, Europe was in fact struggling and for the reasons that I felt in my gut:https://x.com/levelsio/status/1784943280171467260I felt we had to at least try do something to change the mindset in Europe. I started eu/acc, European Accelerationsim as an offshoot of e/acc, Effective Accelerationsim, a similar movement by Beff Jezos in the United States. Out with the pessimism about the future, and in with optimism about technology and the future. And in particular in eu/acc's case: draw attention to the problems of Europe and propose practical ways to fix them.eu/acc is a movement to deregulate and save EuropeThousands of people have now crowdsourced tens of thousands of ideas of which the most important ones have now become part of the official eu/acc manifesto on euacc.comAnd it hasn't just stopped there: eu/acc's ideas are part of Mario Draghi's European Competitiveness report which was presented to the European Commission in September 2024 and implemented in January 2025 by Ursula von der Leyen as the European Competitiveness Compass.Of course that's just reports. We need actual action and laws changed to make Europe a great place for people and business again. And to guarantee its economic future.One of the most important components is not regulation, but deregulation: remove regulation that makes it impossible for tech entrepreneurs, startups and companies in Europe to do business and compete with the rest of the world.Because Europeans are highly skilled, highly educated, they have great ideas, and many are actually ambitious. They're just stifled by regulation and as a consequence a culture that has slowly become so risk-averse that it's been starting to self-sabotage its future.Europe can be great, so let's make it that again! 😊Today I'd love to answer your questions, and I'd even more love to hear YOUR ideas on how to save Europe!-A proud 🇪🇺 EuropeanFollow @euaccofficial to get updates

Thank you for supporting Tanka!
🎉 What a week. What a ride! Tanka just launched this week, and thanks to all of you, we didn’t just launch—we took off. 🏆🚀We set out to introduce the world’s first messenger with AI long term memory for teams, and the response has been nothing short of incredible. You didn’t just support us—you rallied behind us, upvoted, shared your thoughts, and made this moment even bigger than we imagined.We hit #1 Product of the Day, and soon, we’re coming for Product of the Week. But this isn’t just about rankings—it’s about the community that made it happen. You are the early adopters, the builders, the thinkers who see the future and want to shape it.When we started building Tanka, we knew that fragmented conversations, lost context, and scattered knowledge were some of the biggest productivity killers in modern teams. We wanted to fix that—not by building just another chat app, but by creating a Chief Memory Officer for every team. A system that doesn’t just store information but understands it, retrieves it when needed, and helps teams think and work better.Thanks to you, that vision is now out in the world. And the value about this platform goes beyond the recognition. You, the amazing community on this platform, has been helping us shape our product roadmap. During our launch, I got dozens of DMs from makers, founders, and builders sharing their thoughts. A few stuck with me:"I need to separate work from different clients, but I also want my AI assistant to understand the big picture across them. Can Tanka help?"→ This is leading us to explore AI auto-folder grouping and multi-context understanding. We've added these requests to our Q2-Q3 roadmap."I spend hours summarizing interviews and manually creating social posts. What if Tanka could summarize, generate highlights, and even draft Twitter/LinkedIn posts?"→ Expect AI-generated content from insights, seamlessly turning meetings into blog posts, interviews into summaries, and ideas into shareable content."I schedule so many Zoom calls—if Tanka could just auto-schedule, send invites, and summarize meetings, that would be a game changer."→ We hear you. This is great feedback. We're exploring the integration now....And for that, thank you.If you haven’t yet, we’d love your support to push for Product of the Week—not just for the votes, but for the conversations, the feedback, and the shared belief that memory should work for us, not against us.🚀 We’re just getting started. Let’s show the world what work looks like when AI actually remembers.— Kisson & The Tanka Team

🧠 Best way to come up with profitable ideas?
SPOILER ALERT: Focus on YOU.The last 3 months, I have been doing a lot of research on that topic. I have now identified a pattern when it comes to generating ideas that can lead to profits. Ideally this works for app ideas, but apply it to anything.It is all about asking the right questions. The old way of "what opportunities you see in the market", "what others struggle with" do not really work anymore. COVID, put us in isolation. This was a bad experience. However, this generated a "wave" that did not exist before that much.You spending a lot of time alone, means more problems arise that are around YOU.Here is the questioning I do:What activities do I do daily online? - Include anything, from weather checking, to binge scrolling.What apps do I use daily?Why do I use those apps daily? - this helps identify what you really care about, good or bad.What takes me a lot of time to do DAILY?For what things do I pay money DAILY/WEEKLY/MONTHLY? - answer for all the 3 different timeframes.On what apps do I spend more time on?In those particular apps, is there a valuable resource that is not shared? Try to find IDLE resources in the apps you use.What online resources do I have that are not shared with anyone yet?The thing that takes me a lot of time daily, can it be done in another way?Open your bank mobile app, check the services you paid for the last 3 months and ask yourself - What problem did I solve by paying this? Can it be done differently?These are my top questioning techniques to identify things THAT MATTER TO ME. And If I am willing to pay for them, probably there is a market out there.As Kevin Kelly said: "The new big thing will be about sharing an abundant resource we have been using that was not shared before!"Happy Friday.

Do you think AIs can be conscious?
Yesterday, Microsoft's Majorana 1 was launched here, a prototype of a quantum processor powered by topological qubits, a breakthrough that may enable quantum computers capable of solving real-world problems that are intractable with classical computers. As @chrismessina and @terrence_kelleman mentioned, some scientists believe that quantum effects give rise to consciousness, including the mathematician, physicist and philosopher Roger Penrose (Nobel prize 2020).However, most scientists seem to believe that quantum effects are not relevant to information processing in the brain, and many AI researchers (e.g. Ray Kurzweil) think it will be possible to create generally intelligent robots that behave completely as if they were conscious (using classical processors), and then argue that we would then have to assume that they are indeed conscious, just like we do with other humans. Whether / which AIs or robots are or will be conscious, and if they can suffer, is of course a crucial question because of the ethical implications (the next question then would be if people will even care, considering the staggering indifference towards the suffering of animals).All the below options are compatible with our current scientific knowledge (and there are further possibilities). What do you believe?Do you think we will ever find out for sure?The problem is of course that it is impossible to “measure” consciousness directly from the outside. We should be aware that we can't even proof that other people are conscious (the possibility of zombies is not as far-fetched as most people think: If we live in simulated reality, which some very intelligent people think is probable, whoever runs the simulation may have decided for computational or ethical reasons not to simulate all people in a way that they are conscious).

The differences between prompt context, RAG, and fine-tuning and why we chose prompting
When integrating internal knowledge into AI applications, three main approaches stand out:1. Prompt Context – Load all relevant information into the context window and leverage prompt caching.2. Retrieval-Augmented Generation (RAG) – Use text embeddings to fetch only the most relevant information for each query.3. Fine-Tuning – Train a foundation model to better align with specific needs.Each approach has its own strengths and trade-offs:• Prompt Context is the simplest to implement, requires no additional infrastructure, and benefits from increasing context window sizes (now reaching hundreds of thousands of tokens). However, it can become expensive with large inputs and may suffer from context overflow.• RAG reduces token usage by retrieving only relevant snippets, making it efficient for large knowledge bases. However, it requires maintaining an embedding database and tuning retrieval mechanisms.• Fine-Tuning offers the best customization, improving response quality and efficiency. However, it demands significant resources, time, and ongoing model updates.Why We Chose Prompt ContextFor our current needs, prompt context was the most practical choice:• It allows for a fast development cycle without additional infrastructure.• Large context windows (100k+ tokens) are sufficient for our small knowledge base.• Prompt caching helps reduce latency and cost.What do you think is the better approach ? In our case as our knowledge base grows, we expect to adopt a hybrid approach, combining RAG for scalability and fine-tuning for more specialized responses.
