Show HN: We built a multimodal AI interviewer for mock system design interviews
Hey HN! We’re Jared, Shreyas, and Varun the creators of TechInterviewer. We’re building a product for software engineers to go through an entirely simulated systems design interview. Our AI interviewer, Steve, gives you a prompt and you talk out loud and draw on a whiteboard while Steve guides you through the interview and gives real-time feedback. Check out our demo:<p><a href="https://app.techinterviewer.ai" rel="nofollow">https://app.techinterviewer.ai</a><p>Every software engineer today has to prepare for systems design interviews and have two awful options: pay hundreds of dollars for a single session with a FAANG engineer or follow silently alongside a YouTube playlist. Because there is no instant feedback while practicing, engineers often learn about their most important knowledge gaps during the course of the interview loop.<p>Jared and Shreyas are both senior engineers who have spent 1000s of hours preparing for and administering systems design interviews. Shreyas was an early engineer at Deepgram and spent many years tracking developments in the TTS (text to speech) space. He realized that voice interviews had potential to change the candidate experience when he starting using chatGPT to prepare for interviewing founding engineer candidates at his startup.<p>We’re hoping that having easy access to interview feedback will level the playing field of software engineers at different skill levels. We’re really excited to share this with you all and we’d love any thoughts, feedback, and comments
Show HN: Roundtable – Survey fraud and bot detection API
Hi HN, we're Mayank and Matt of Roundtable (<a href="https://www.roundtable.ai">https://www.roundtable.ai</a>). We launched our Survey Simulator as part of YC S23 (see Launch HN: <a href="https://news.ycombinator.com/item?id=36865625">https://news.ycombinator.com/item?id=36865625</a>), and ultimately decided to pivot because we couldn't convince users to trust our results and our value proposition wasn't clear.<p>We conducted tons of user discovery interviews, and a lot of big players talked about the pain of manual QC and bot detection. We launched a survey fraud and bot detection API (Alias; docs.roundtable.ai) that determines whether a bot is answering your survey or not. Our API embeds Javascript into survey programs (Forsta, Qualtrics, jsPsych, etc.) to track user behavior and make a judgment on whether the data is from a high-quality participant.<p>You can use our demo, and try to break it, here: <a href="https://www.roundtable.ai/hn-demo">https://www.roundtable.ai/hn-demo</a>. See if you can generate LLM-based text without any flags going off! Feedback welcome!
Show HN: I built presently.live for better weekend planning and insights
Hi HN , my partner and I were looking for easier answers to our weekend planning ritual, such as:<p>- When is our next free weekend?
- What weekend activities have we got planned?
- How busy/available are we to travel / host?<p>Especially at the start of each year, when we're trying to plan flights and/or commit to hosting friends & family visits, I struggled to find a usable overview of multiple months that wasn't cluttered with weekdays. Our social events are overwhelmingly centered around weekends and we wanted a view of the year ahead that reflected that.<p>How about just a line of 52 boxes, one per weekend ahead, shaded differently whether it was free or maybe busy or definitely busy? That was the initial sketch on a napkin that lead to a first proof of concept script that I ran locally.<p>Now, it's a webapp* that reads from our calendars (Google only for now, sorry) to visually summarise weekends - all with readonly access. I've since added some calendar-write features from there ("pro" version, completely free) as our lives become busier with a dog, and parenthood more recently. Features like event templates, summarising events by hashtags, flagging draft/unconfirmed events etc.<p>We've been using it to scratch our own planning itches for some years now already, and I'm sharing here now in case it can be useful for others. Even better if you have any feedback.<p>What / how have you hacked to get clearer and direct insights into your time?<p>I think time management and calendars have been lacking a UX overhaul for a long long time so it's a space I'm passionate about tinkering within.<p>*stack is Nuxt 3, backed by Supabase, hosted on Cloudflare Pages.

Show HN: Lightweight Productivity Tool
Hi HN!<p>I’m the founder of Zlinky (<a href="http://Zlinky.com" rel="nofollow">http://Zlinky.com</a>).<p>Zlinky is an app that helps you save and organize your links and screenshots. We have worked hard to keep the app very simple. We also have a web version and a Chrome Extension.<p>I was inspired to build this app as I was struggling to find an easy way save / organize / revisit / connect ideas. I couldn't find an existing tool that was lightweight and purpose built.<p>I spend a LOT of time consuming content, and I felt that I wasn't being effective revisiting the highest quality content for work or personal purposes. My screenshots were also in a mess and that one important screenshot often got lost.<p>I learnt about building prosumer apps as the Co-Founder of ManageFlitter (RIP). We scaled ManageFlitter to over 4 million users. Eventually Twitter refused most of our most valuable features. The ManageFlitter story captures the crazy rollercoaster that was building on top of the public Twitter API.<p>Zlinky has a very generous free account that should be sufficient most users for a long period of time.<p>Would love to get your feedback, questions, and ideas. Thanks! :)<p>Kevin
