Show HN: Summary Cat, a YouTube Video Summary Generator Hello HN! Please check out Summary Cat ( https://ift.tt/5qvwkAh ). It uses OpenAI's GPT-3.5 to summarize YouTube transcripts. Please note that it only works for *English* videos right now. I'd appreciate any feedbacks, criticisms, or feature requests!! You can also find my contact info in my profile. Thank you in advance. --------------------------- Tech Stack - Frontend: HTML/CSS - Backend: Python/Flask APIs: - For grabbing YouTube's transcripts, I used youtube-transcript-api ( https://ift.tt/lTiPsxO ) - For summarizing the transcripts, I used OpenAI's GPT-3.5-turbo-16k: https://ift.tt/WSB5zwG . (I used GPT-3.5 because GPT-4 is quite a lot more expensive (roughly 10X). https://ift.tt/5qvwkAh September 23, 2023 at 01:54AM

Show HN: Learn piano without sheet music https://ift.tt/hz5ROLv

Show HN: Learn piano without sheet music I always found sheet music way too hard to read - and I literally spent a year at a company building a sheet music rendering engine. I wanted an app that would display music like the tutorials on YouTube, but not be focused on upselling lessons etc. like most current apps, and also would let me import my own files This works on MIDI files. If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a subscription - which has absolutely tanked revenue so far - but maybe it will pick up Would love to hear your thoughts and if you have any suggestions! https://ift.tt/c4LJUDi September 22, 2023 at 06:32PM

Show HN: Corgi – on-demand, 1-on-1 tutoring https://ift.tt/aLBjWrh

Show HN: Corgi – on-demand, 1-on-1 tutoring Hey all — I’m Sameer, a software engineer and longtime math/CS tutor who’s just launched an on-demand tutoring platform called Corgi. The product is a mobile app (currently iOS only) that allows users to request and receive tutoring help whenever they want it, for as little or as long as they need. Here’s how it works: 1. User selects a subject, adds a brief summary of what they need help with, and submits their request 2. All tutors who are online and qualified in that subject receive a notification that someone needs help 3. The first tutor to accept the request gets matched with the user, and both parties are placed in a in-app video chat session 4. The user works with the tutor for as long as they need 5. When the session is complete, the user is charged for the time they used (currently billed at $1/minute, rounded to the nearest minute) and the tutor receives 80% of the student fee As a starting point, the only subject we’re offering is SAT math help, but we plan to expand to other subjects in the near future. I built Corgi because 1) tutoring is a lifelong passion of mine, and 2) I haven’t found a quality, on-demand tutoring service that currently exists, but I believe it’s something that could really help students. The idea here isn’t to try and replace the traditional tutoring model (i.e. working with the same tutor on a consistent basis over a long period of time) but to supplement existing resources with an office hours-like service that can provide immediate help (e.g. at the exact moment when someone is struggling with homework, or is studying for an imminent exam). Eventually, I’d like to offer this platform directly to schools or districts, so that students can use it irrespective of ability to pay. There is at least one major player in this space doing something similar ( https://paper.co ) but from my own research they seem to have a lot of issues (e.g. students getting matched with tutors who aren’t qualified in their subjects, tutors working with many students simultaneously despite the company claiming the tutoring is all 1-on-1) and districts who previously signed contracts with them don’t seem keen on continuing their relationships ( https://ift.tt/WpVklP0... ). I’ve also been a tutor on some of the existing traditional tutoring platforms (e.g. Wyzant) and have found the experience frustrating (mainly due to unfairly low compensation combined with a struggle to match with students). My goal with Corgi is to build something that provides real value and a positive experience for both the tutors and students who use it. I’ve spent the last week or so recruiting an initial batch of tutors, and am now kicking off the process of finding students to help test it out. I’m also building out some additional features to help make the actual tutoring sessions feel a little smoother (e.g. browser-based sessions to allow usage from any device, virtual whiteboards for easier collaboration). I’d appreciate any and all feedback the HN community has to share, positive or negative! https://ift.tt/8ZSuMQz September 22, 2023 at 07:53AM

Show HN: A website that gives voice to unfulfilled customer needs https://ift.tt/Hl9WCPA

Show HN: A website that gives voice to unfulfilled customer needs How does it work? You just write a short title of what you want like “24/7 cafe in my town”, a short description why you need it - “I like to work late, don’t like to work at home and all coffee places close at 9” and how much you would pay per visit. If many people subscribe to your idea, hopefully someone will see it and open that coffee shop. You can also see what others want and maybe get inspired. Or you can just use the website to track your ideas. What problems am I trying to solve? 1. Many startups fail because they build something that customers do not want 2. Customers do not get services they need because their voices are not heard This project attempts to solve the two problems by giving the voice to the customers and a platform for startup founders to research customer demand backed product ideas. The project is at its earliest stage, so any feedback, bug reports and feature requests are welcome! https://ift.tt/3GwiTyo September 21, 2023 at 05:17AM

Show HN: Mana Pool Hi folks. I launched my first startup on HN 15 years ago (see my profile), and I wanted to post here again now. Like my last one, this project comes from one of my life's passions. I have played Magic: The Gathering for 30 years. My co-founders and I think Magic deserves its own market, and this thinking will lead to dozens of ways to make a great app. We consider what we have an MVP, and we are all going to MagicCon this weekend in Las Vegas to walk around in our Mana Pool shirts and talk to people about the future. If HN likes the site, I would appreciate you crashing it before we head out tomorrow night! https://manapool.com/ https://manapool.com/ September 20, 2023 at 10:31PM

Show HN: Hydra - Open-Source Columnar Postgres https://ift.tt/ScyihpW

Show HN: Hydra - Open-Source Columnar Postgres hi hn, hydra ceo here hydra is an open-source extension that adds columnar tables to Postgres for efficient analytical reporting. With Hydra, you can analyze billions of rows instantly without changing code. demo video (5 min): https://youtu.be/1yzxgb0Oyrw github repo: https://ift.tt/9Yc5ICs For 1.0 GA release, aggregate queries are over *60% faster* than Hydra beta due to aggregate vectorization. Spatial indexes (gin, gist, spgist, and rum indexes) and pg_hint_plan are now enabled for performance optimization. postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without changing code. for testing, try the hydra free tier to create a column postgres instance on the cloud. https://ift.tt/NJ7uHYn https://ift.tt/qtDIeL1 September 19, 2023 at 09:35PM

Show HN: Focusdoro(AI) – AI assisted Pomodoro task list https://ift.tt/7o6DPL3

Show HN: Focusdoro(AI) – AI assisted Pomodoro task list Hi, I have always struggled with changing priorities and figuring out what to focus on a particular day. The actual priorities get missed amongst all other things in life. With the launch of Gen AI in almost all aspects of our lives, i decided to build something that can assist me in finding the right priorities and staying on them. This has helped me out for the past couple of days. I am using Openai apis for task breakdown and Daily planning bot and the rest of the site is built using Django, JS, and Tailwind. I have tried a lot of productivity tools throughout the years and Pomodoro and timer-based focused work has worked out best for me. If there are other techniques that have worked out for you, do let me know, I will try to incorporate those :) Would love honest feedback on this so that I can make this more useful to others and to myself. Looking forward to your feedback, thanks in advance :) https://focusdoro.com September 19, 2023 at 08:13PM
