Show HN: Spreadsheets Cells with Uncertainty Distributions
https://github.com/PragmaticMachineLearning/maybe
Hi HN,I built a spreadsheet for modeling uncertainty directly in cells.Cells can contain probability distributions, ranges, or distributions inferred from confidence intervals. Formulas then propagate that uncertainty through the sheet.For example:A1 = N.CI(10, 20)B1 = U(2, 5)C1 = A1 * B1Instead of a single value, C1 becomes a sampled result.The formula engine is powered by GaussFormula, a...
Show HN: A tool that makes sense of Reddit and YouTube product reviews
It's basically an AI-powered scraper that pulls reviews from Reddit and YouTube, then structures all that messy data into something actually useful - pros, cons, sentiment analysis, and an overall "should you buy this?" recommendation. Built it with FastAPI, Next.js and PostgreSQL, all wrapped up in Docker.
Looking back, I probably should've just made it a simple CLI tool instead of a whole web app. Would've saved me a lot of time...
Still rough around the edges, but the core works. Code’s on GitHub if you want to tinker
Unlike Jupyter or Deepnote where you write code directly, Probly is primarily prompt-based - you describe what analysis you want in natural language, and the AI generates and executes the appropriate Python code behind the scenes using Pyodide.
The key difference has to be that Probly runs python entirely in your browser using WASM, while jupyter/Deepnote run code on servers.
Glad to hear the setup was smooth and that the chat box + import/export features worked well for you. Noted on the UI tweaks, I'll look into making them more intuitive.
On the categorization issue, yeah, LLMs can struggle with nuanced transaction labeling, especially without proper context or examples. Structured prompting could help, which ties into your second point -- having a library of refined prompts that can be reused for repetitive tasks would be really valuable.
I love your feedback -- it's exactly what helps improve the tool. And again, thanks for testing it out!
Probly is earlier stage and more minimalist, but we're tackling the same fundamental problem. Our specific focus is on making data analysis a fully autonomous process powered by AI - where you can describe what you want to learn from your data and have the system figure out the rest.
This is something we're considering for future development, so this is a great shout!

Right now, you can clone the repo and follow the instructions to run it locally with your own OpenAI key. I'm working on a hosted demo that will let you try it out directly without any setup. stay tuned :)
Show HN: Probly – Spreadsheets, Python, and AI in the browser
https://github.com/PragmaticMachineLearning/probly
Probly was built to reduce context-switching between spreadsheet applications, Python notebooks, and AI tools. It’s a simple spreadsheet that lets you talk to your data. Need pandas analysis? Just ask in plain English, and the code runs right in your browser. Want a chart? Just ask.While there are tools available in this space like TheBricks, Probly is a minimalist, open-source solution built...
I'm excited to share my project, Degrees of Torvalds. Inspired by the "The oracle of Kevin Bacon" concept, this tool maps the open-source community by tracing connections to Linus Torvalds through GitHub commit histories.
What is Degrees of Torvalds?
Degrees of Torvalds lets you visualize how any GitHub user is connected to Linus Torvalds. By analyzing commit graphs, it reveals the collaborative network within the open-source ecosystem. This first iteration features a straightforward user interface that shows a given user's connection history to Torvalds.
Why Did I Create This?
The project celebrates the interconnected nature of open-source development, illustrating the collaborative spirit that drives it. Whether you're a seasoned developer or new to open-source, Degrees of Torvalds aims to inspire by showing how close you might be to one of the community's most influential figures.
Technical Details:
Backend: Built with FastAPI for efficient request handling. Frontend: Developed using React for a smooth user experience. Deployment: Hosted on Google Cloud Platform for scalability and reliability. Try It Out! Explore Degrees of Torvalds at sixdegreesofgithub.com. Your feedback and suggestions are welcome!
Happy coding!
