... what it actually does: It sees your screen and acts on it Not summarizes. Not suggests. Clicks, scrolls, fills forms, and navigates any page, on its own. It builds Google Sheets and Docs from scratch "Make me a competitor pricing table with graphs." It opens the tabs, pulls the data, formats the sheet, builds the charts. You just watch. It runs WhatsApp & Telegram like a personal assistant Broadcast to 50 contacts at once. Send follow-ups with Word docs ... ... attached. Message from your phone, get a finished file back. Nobody else does this. It monitors pages and pushes you alerts Price dropped? Ticket available? Competitor

... Most interview prep tools are built for one moment: interview in 2 weeks. You cram. You close the tab. Six months later, you panic again. The problem isn't the tools. It's the model. Cramming 3 days before a loop is like going to the gym 3 days before a marathon. The work should've happened months ago. DailyKnack is the daily habit layer. 7-10 SDET-specific questions every morning Playwright, CI/CD, API testing, agentic/LLM patterns, contract testing ...

... made them succeed or fail? For those who've sold into small/mid-sized businesses, what's usually the biggest blocker to adoption price, integration effort, or something else? Is there a feature here that seems like a "nice to have" versus something that would actually change behavior? Would appreciate any perspective, whether from experience building similar things or just as someone who's dealt with this as a customer or business owner. Comment from Tommy Kang(@sjtkang): What I'm building ... ... real users through forums and word of mouth? that's the kind of hustle most "growth hackers" pay thousands for courses to learn lol Comment from Jin Ci(@youliqn): honestly the post-launch waiting game is real lol. you prep

... busmark_w_nika  that's fair, popular hunters/people that have been in the community for a while definitely come with credibility. Comment from Denitsa Pencheva-Valtchanova(@denitsapenchevavaltchanova): You mention a hunter - curious, do you think it brings value Vs self-hunting. I see both self-hunted and hunted by a popular hunter products reach "Product of the Day" Comment from Eden(@builder_eden): Saving this one.

... ever had to prep a codebase for a SOX audit, a PCI-DSS review, or a FINRA examination, you know the pain: engineers write the code, compliance officers need to understand it, and the gap between those two worlds is expensive. We built compliancedoc to close that gap a VS

... tired of the noise in technical analysis. Some people swear by RSI, others rely on EMAs. But when you try to average them, you realise a static average doesn't work because different indicators dominate different market regimes (trending vs cycling). To solve this, I spent the months building an engine (TickerSignals) that scores 39 indicators across 6 layers daily for 2,500+ stocks. To calibrate the weights, I backtested roughly 2L+ historical signals. Here are my two biggest takeaways ... ... transparent, you can click any stock on the platform and see the exact breakdown of how all 39 indicators scored and the track record.

... didn t realize how expensive the #INBDE process was for dental students until someone close to me started studying for it. The exam itself cost over $1,000 and prep materials can easily add hundreds more. So I built Teefs Prep

... Hello everyone I'm a software engineer currently switching jobs, and the prep process has been frustrating. Editing my resume in one tool, asking ChatGPT for suggestions in another tab, never really knowing if my resume was landing the right signals for the roles I was targeting, and practicing answers only in my head with no idea whether they were actually comprehensive enough. So I built a job prep

... months ago. As excited as I was about building a startup, I felt paralyzed by the lack of direction and structure that came with it. I familiarized myself with various web design software and marketing strategies, treating them as prep work for when we "get serious" about officially launching it. I did not take the initiative sooner because, while Bailey grew up in the startup world, I had no idea what was "supposed to happen." I was waiting ... ... okay not to know. The relief hit so hard that I was confident enough to finally take the initiative and stop seeing every decision as a test I could fail. The web design tools, the marketing strategies, the "prep

Two asks: If you've launched before, what's the one thing you'd tell a growth team member prepping for their founder's launch? If you're launching around the same time as us (mid-to-late April), drop it below. I'll be in comments all day on the 22nd and happy to return the favor for yours ...

... product page, support email, docs, and social handles brand-owned from day one. That way the founder can create context without making the whole asset impossible to transfer later. We are doing this with Offer.cc in the AI interview prep space: the founder voice is useful for explaining real candidate pain, but the durable asset has to be the product promise itself: helping developers map a JD, predict interview probes, practice coding/system design explanations, and review misses after the call ... ... founders do not think about ownership later. Comment from YekSoon Lok(@ys_askodin): Having operated on both sides of the table as an allocator and a founder, I view this through a different lens. The binary of "personal brand vs

... Frank. I'm building Four-Leaf, an AI career prep platform that organizes everything around each job application. The thing that bothered me about existing tools was everyone prepares for interviews by reading answers on a screen. Then they freeze when they have to say it to a real person. Typing "tell me about a time you led a project" and speaking it under pressure are completely different skills. So Four-Leaf does full voice mock interviews. You speak your ...

... Looks like there are 300+ places one can "launch" their product these days, but I know PH is one of the top. I didn't realize how much work went into a proper and successful launch, so I'm prepping for that. I'm a developer, not a marketer, so we'll see how it goes. Let me know how I can help you! Comment from Rian Robertson(@rianbrob): Congrats on finally shipping after 15 years...that's huge! Love ... ... still hands-on. Clients wanting it right away is a great sign.

... employees as well as the field I'm specifically targeting. Started Shortlist because I kept seeing the same problem: founders spending weeks and $20K+ trying to hire one sales rep when the whole process could be 10x faster. Prepping for a PH launch soon and want to actually be part of the community here, not just show up on launch day asking for support. So here I am. Happy to connect with other builders. If you're hiring for sales ...

... Managers spend 3 5 hours every week on meeting prep, follow-ups, and trying to reconstruct conversations from memory. I ran the numbers and it s roughly a $10K $30K/year problem depending on role. But the real issue isn t just time. It s what gets lost: missed follow-ups inconsistent feedback reviews based on recent memory instead of reality I ve seen this pattern across companies for years, so I started building something to address it. It s called ... ... AspectOS. The idea is simple: capture moments as they happen (wins, issues, coaching) use that to prep

... which I'm genuinely happy with, but the real work now is converting the traffic that came in and keeping the momentum going in the weeks after. That part gets almost no attention compared to launch day prep. Comment from Aleksandar Blazhev(@byalexai): @ruxandra_mazilu  Oh yeah. When you re doing it for the first time, you honestly have no idea how much time you ll need. And there are almost always delays on the development/production side ... ... planning to launch? Comment from Eva(@eva_shivers): @byalexai  Thank you for your thoughts and experience! Comment from Eva(@eva_shivers): We launched two days ago and this resonated deeply. Our biggest takeaway wasn't about prep

... conversations vanish into the ether. Expectations get fuzzy three days after a 1:1. I started building the Vertex Suite to solve this. I'm currently refining AspectOS , which acts as a "Leadership OS" to capture real-time moments, prep for 1:1s, and ensure nothing falls through the cracks. It s the tool I wish I d had for the last decade. I m currently in the "lab" phase with a dozen testers (from frontline managers to CEOs ... ... from this community before a full "Product of the Day" push. I d love to hear from the leaders here: What part of managing people feels the most chaotic for you right now? Is it the follow-ups, the prep

... problem. The freelancers I built for aren't looking for a free tool they're looking for the right one. If 7 days isn't enough to know, the product isn't good enough yet. Your point about generalized vs tailored is exactly the right framework. The free tax calculator I built gives anyone a general estimate no signup, instant value. The paid dashboard is the tailored version your clients, your real numbers, your specific situation. Free = the concept. Paid ... ... just letting it rip .
