24 alternatives to I made a cheap alternative to college-level math & physics tutoring
Hi everyone! I’m the founder of Explanations (https://explanations.app). I’m building a website where students can get college level math & physics help for 1/10th the cost of private tutoring. You’d type a question, and your teacher replies by drawing a Youtube/KhanAcademy-style video; and this happens asynchronously throughout the week. When I was studying at MIT, I often had to wait 40-60 minutes in line just to get 5 minutes of “help” from a TA - when I needed 1-2 hours. I understood that TAs can’t spend all their time helping me. That’s understandable. But what made…
Explanations is a website offering college-level math and physics tutoring at a fraction of private tutor costs. Students submit questions and receive asynchronous video responses from instructors who draw out… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a cheap alternative to college-level math & physics tutoring launched in 2024; newer entries below may have overtaken it.

Good math problems are hidden inside textbooks and online documents. To keep up with all the sources in the world is hard. For someone who just wants to continuously solve problems, finding and going through all the sources feels like a hassle. I wished for a website that could just dump all the math problems available in the world out there. And if I could filter the problems by topics, that would be beautiful. teachyourselfmath is a side project that was born out of this need. At its core, it is a math PDF extraction engine. The engine has some machine learning going on behind the scenes…

Wondering▲345Hey HN! I’m excited to show you my app that lets you learn any topic in a structured, bite-sized way. Each lesson has an audio version, some visuals, and interactive quizzes. They’re personalized to your background and goals, and you can pick a concept inside a lesson and ask it to go deeper. When my co-founder was at NotebookLM, he realized the biggest bottlenecks in learning are that people don’t have time or feel like they’re not smart enough. We wanted to see if software can take the mental load of figuring out what resources to use and what order to learn them in, and make lessons easy…

Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

I strongly believe that every developer is a teacher and likewise. Every time you are asked to help someone else understand your code, you’ll always be grateful to be able to share your own knowledge with others. Explain Code App is the place you can make this happen! I am eager to hear your thoughts on what I have put together so far. Would love to hear your feedback! Let me know if there are any other features you would like for this site, I’m open for ideas and would love the community feedback. Here is the link: https://www.explaincode.app/

Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…

Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even…

Hey HN, I’m a dev and a dad to a 10-year-old. I built this because I caught my daughter using ChatGPT to do her history homework. She wasn't learning; she was just acting as a "middleware" between the AI and the paper. The Backstory: I realized the problem isn't the AI—it's the zero-friction answers. Most "AI for kids" apps are just "parrots"—they mimic intelligence by repeating patterns. What’s Different: Qurio is a "Bicycle" for the mind. It treats the child like a future "Architect" rather than a "Junior Executor." Technically, it wraps an LLM in a strict "Socratic Loop." It detects…

Torial▲17I'm a huge fan of 3B1B and how he creates appealing and easy-to-understand videos. But he doesn't have a video for every single topic. Whenever I needed help in math or physics, I would try to watch his videos but the issue is that are just not specific enough to my content or curriculum. This issue applies to every single video explanation out there, they just aren't personalized. Most educational videos explain general topics, but they don’t align perfectly with the specific question I have or the way I need it explained. That’s the gap I wanted to fill. So I built a tool that generates…

Hi HN, we’re building deriveit.org, the website where you can learn any topic, quickly. On our website, you pay to ask any physics, computer science, or math question, and our community competes to give you the best explanation (for a cash reward). Right now, resources with high quality content are a time drain (papers, textbooks, and courses). We think that material is typically written in an unnecessarily hard-to-read way, but that there are tons of people who are passionate about explaining it well to others. We want to give the world access to those people, and remove barriers for them…

My niche is LSAT prep. I write books of explanations to LSAT practice tests. It's a pretty big industry, as people will pay a lot to improve their odds of law school admissions. I realized that, with my books, I have ~400,000 words of quality content that people search for. Lots of long tail searches for individual LSAT questions. So I made a site of free explanations for the most recent LSAT: http://lsathacks.com/ Took about a week to write them and put them up. If it goes well, I'll release my other explanations. Hope to make this a hub for LSAT study. If it's well received,…

This course was intended for ages 7 and up, including adults. I really tried to make the material accessible to everyone, and hopefully not be too boring, while it establishes a solid foundation for learning anything else. If you do watch it, let me know if it is helpful in getting a solid foundation! My background: Before I got full-time into software development, I was doing a Ph. D in math at NYU. I thought YouTube needed something like this.

Hi HN, I'm Ben, a solo developer. I've just launched ELI5 GPT: https://explaintome.netlify.app, a simple tool that utilizes GPT to explain anything in very simple terms — as if you're 5 years old. I built it because I was tired of having to Google explanations for tech topics that were either too complex or filled with jargon. I wanted something minimal, fast, and fun — no logins, no bloat. It's built with plain HTML, CSS, and JavaScript, hosted on Netlify. You can enter any concept (e.g., "quantum physics" or "inflation") and it'll explain it at a childlike level using AI. It’s…

Hey HN! I'm Dris, a 17y/o solo founder. Over the past few weeks, I've been developing LIRA, a free Chrome extension that helps you take notes & get instant answers on any site. Instead of switching tabs or copying/pasting to ChatGPT, just select and right-click text, images, or links to save a note or ask LIRA anything. LIRA can instantly find accurate answers, summaries, and explanations, and automatically highlights correct answers. I made LIRA to help busy students like myself study smarter, not longer! That being said, LIRA is still a work in progress. There may be a few bugs &…

Cut to the chase: https://www.youtube.com/watch?v=4nyzl3pVXp4 I really am a big supporter of quality education being available for everyone, and because of that I've opted to open source my CS education on YouTube. I'm starting with Rails, and I will eventually work around to more core CS topics like circuits -> logic gates -> binary -> assembly -> c -> Data Structures -> Algorithms etc. If you like it subscribe and I'm looking for all the feedback I can get on how to make it better :)
