Alternatives
Products that do what Calendly alternative where LLM decides which slots to show does
During my fundraise, I had 6 Calendly links I was managing actively. My goals were: 1. Investors should always find links comfortable to their timezone 2. They should not see full day slots thinking I am free throughout the day ( wrong sign ) 3. So I had to manage multiple calendly for every timezone and opening slots - when one close. I really wished someone would have given me power to add all these things just as agent instructions for AI to decide - and we did it now. buxo.ai for everyone.

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so. Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you're coming to the wrong place, but feel free to yoink the code. Its just one fat index.html file. Served off my VPS via…

I'm Canadian, live abroad, and my money is scattered across two countries, multiple currencies, banks, brokerages, real estate, and some private equity. No app could hold all of it, and none could answer a simple question like "what's my actual USD exposure?" Brisa pulls everything together (Plaid + manual accounts + real estate + PE, all multi-currency) and puts an AI on top that has my full financial picture in context. Instead of clicking through charts, I can just ask. Would appreciate any feedback!

I got tired of trying to figure out my vacation balance throughout the year, so I made this website to be a stupid simple solution. It was pretty satisfying to bang it out over a weekend. * not all holidays are supported, and probably will do some custom-holiday-in-cookie functionality, but this is a common US list. * basically only looks good on 'normal' sized browsers

I've spent the last couple weeks working on getting this up and running. It's my first web app. The use case it is designed for is for shift workers who work x days on, y days off. So if you ask them "Are you going to be able to go to my wedding on July 15, 2012" they have no idea. This helps solve that problem. Feed back as always is appreciated.

Hey HN, I just updated my project that compares some LLMs. It uses your prompt for all the models and runs at the same time. You can see the results being generated in real-time and decide what's the best for your use case. I'm open to any suggestions and feedback. Thanks!

Hey everyone, Through my career, I've spent too many hours and too much mental load on busywork like scheduling and following up on people's availabilities. So, I built Carrie. You simply cc her into your emails, and she sorts out meeting times across time zones, finds what works best for everyone, confirms the meeting and sends the invite. She handles scenarios beyond what Calendly can handle and it’s been freeing me up from the back-and-forth of juggling different meeting requests. I’ve been testing this with a beta group of users and am now looking to expand the user pool (please feel…

I use multiple AI tools for work and also my side projects, and the annoying part was to track my costs and token usage across tools. Everytime I had to visit each tool and its respective usage setting to check it and I was losing patience and also was getting hit by surprise limits Now I know that there are already free/open-source trackers for Cursor or Claude usage, and they are useful if that is all you need. My problem is broader as I wanted one small place to see tokens, spend, subscriptions and limits across the AI tools I actually use. I was really tired of switching tabs and…

Hello! For the last year I've been working on a side project, a booking management system. Among others, it allows anyone who owns a business that accepts bookings to manage them, to communicate with customers, to easily create a personalized website or to embed a calendar widget on any existing website. Link: https://www.planorio.com There is still a long way to go, but I feel that now it is ready for some very direct feedback. :) It mainly consists of an Angular frontend, a backend written in Node.js and some small tools written in PHP and Kotlin. I also created a hybrid mobile…

Hello fellow hackers! I love creating products that solve people's needs. One day, my wife asked me if I knew of any tools that could help plan a week-long company getaway. The requirements were fairly straightforward: - 14 people - A 7-day trip - Sometime in the next 6 months They weren’t concerned about choosing the exact time yet; they just needed to know which dates would work for everyone—or put another way, when does it NOT work? I searched but couldn’t find anything that met this specific need, so I decided to build it myself. The concept is simple: think of it as an inverse Doodle.…

Hi HN, When I was in FAANG, I despised ticketing. I was always the eng that refused to update. Then when I was a tech lead, I had the pain of pinging everyone for updates because they hated it too. Things would go out of date, and then no one would really know if we were on track. We also had little visibility into what the team was doing outside of pinging/standups. So I made an AI that looks at every commit you push and updates tickets for you. It can create tickets if there isn't one, update, leave comments, tag associated commits etc... Basically, it's an "AI Board Babysitter" so…

I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

I was with BOFA and Chase Private Client for years before I realized that they were making tons of interest off my money and just keeping it for themselves. The funny thing is that since I had a lot of money with them they raised my rate as a thank you to wait for it 0.02% instead of 0.01% lol. Got upset because of this and made this site. It scrapes all the banks every 30 minutes so it is the most real time source of APY data on the internet. Rates are now over 3% at the high end so it makes sense to park your money in these places rather than the big three banks.

Hi all, Been a while since I've posted and in the time since I have created a trading journal website where you can submit and track your trades with the USP of tracking your outgoings too. There has been a huge rise in the number of retail traders (me included) and a lot of people now have the very real possibility of quitting their day jobs and trading full time. I want to help people do that! It's still in very early stages and I'm releasing new updates daily but would be very grateful to get some other peoples feedback! Thanks in advance and hope you're all having a good day! :D

One station to find per day, 2 or 3 gamemodes depending on the city (if your city is not live yet, or you can't find it in the selector, try https://dailymetro.live/cityname/mode/classic ) Like https://dailymetro.live/sf/mode/classic for San Francisco Got huge traction in France, so I thought maybe you'll like it here too :) Made with Claude code but still took at least 50-100h of dev/design/taking user feedbacks ahahah Hope you like it

Backstory: Few years back, I used a shared spreadsheet (GSheets) to organize my property hunt, and found it quite frustrating to keep on top of things just on the productivity side alone. Felt that there should be a better way to do this, and that's when I started creating a webapp, with features that can make this journey feel less stressful. This is a solo dev project. Have a look at the demo, and let me know your thoughts! Cheers

My partner and I do a lot of planning around things like holidays and trips, which involves a mix of firm, tentative, and overlapping plans, and normal calendars are the wrong fidelity for that kind of planning. We often found ourselves drawing on top of screenshots of calendars with tools like Miro or even printing out calendars we could draw on. We're both product designers, and so we're used to working in low fidelity tools like Excalidraw and FigJam. We decided to try and make a low-fidelity equivalent for calendars, and built Walnut. It's just lines and stickies, with a few different…

Hey HN, I've been working on something cool that I wanted to share with you all. It's called Viewpoint, an analytics tool for LLMs like OpenAI, Anthropic models, and Gemini. The idea came from the constant flood of new LLM models and the need to figure out which ones work best for my projects without breaking the bank. With viewpoint, I can track token usage, costs, latency(WIP), and traffic over time, making it easier to compare different models and see which ones perform best and save money. The tool works asynchronously, so it doesn't add any latency to your LLM requests, and you have…
