24 alternatives to ExplainToMeGPT
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…

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…

heyo! Explainpaper lets you upload a research paper PDF. If you don't understand a formula or sentence, just highlight it and the tool explains it for you I built this a few weeks ago to help me read a neuroscience paper, and it works pretty well! I didn't fine-tune GPT-3, but I do take a lot of context from the paper and feed that into the prompt (not the whole paper). Ppl have uploaded AI, biology, economics, philosophy papers and even law documents. Works in Chinese, Japanese, Spanish, French and more as well!

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…

Hey Hacker News! Launching gptengineer.app into beta today. It's like Claude Artifacts, but: - you can edit the code in your fav IDE (two-way github sync) - installs npm packages - automatically picks up build and runtime errors and fixes them - very fast, built with rust The full stack capabilities are built on supabase (prefer to not have to handle auth + user data at this point so this is owned by the user) The seed for this project was an open source experiment, posted about that previously here: https://news.ycombinator.com/item?id=36422730 Would love feedback if you give…

very much inspired by karpathy's microgpt of the same name. it's (by default) a 4000 param GPT/LLM/NN that learns to generate names. this is sorta an educational tool in that you can visualize the activations as they pass through the network, and click on things to get an explanation of them.

Hi HN, As a developer, I much prefer to write code than read other people’s code. But most projects I work on involve other developers so it’s hard to avoid. Often I find it really hard to quickly parse other people’s code so I thought maybe ChatGPT could help. ChatGPT does a really nice job of giving clear explanations when you paste in code and ask it to explain it. But the interface is a bit of a pain to use if you’re using it many times a day. It’s also hard to share explanations with co-workers. So I built whatdoesthiscodedo.com. Just paste your code and get your ChatGPT explanation and…

OP here. This comment contains SPOILERS so try the dystopia simulator first before reading further! I built "WeChatGPT+" in December on top of GPT-3. It was pretty surreal when OpenAI released an actual product named "ChatGPT Plus" a few months after that. Then the Microsoft partnership was announced, Bing AI was released, and marketing materials were leaked indicating that Bing AI would start including advertisements within the chat responses. Reality imitates fiction, I guess. Today - literally a few hours ago - OpenAI announced public ChatGPT API with 10% the cost of GPT-3. I immediately…

Hi HN — we’re John and Vish! We built WhyBot, a tool to help you deeply explore a question or topic. You ask a question, and WhyBot responds by building an ever-expanding knowledge graph. It does this by recursively generating answers and follow-up questions. You can change its persona to change the flavor of the generations (try toddler mode!). We originally built this for the AngelList Agent Hackathon (https://twitter.com/AqeelMeetsWorld/status/16502799744050421...) and got a lot of interest from folks asking to play around with it. So we thought it’d be fun to…

Hi HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…

"Explain This" was inspired by Github Copilot, where you can get an easy code explanation. So we bring this into a web app for customer support. I believe that chatbots are not it for customer support and that AI has better uses. "Explain This" allows the user to pick any part of web app and get it explained. The explanation is generated on the fly from the knowledge base; no need to have the content prepared; it will figure out the user's context and find the most fitting parts of the text we can then use to generate the content. When implemented it reduces the number of chatbot…
