Quadratic – Open-Source Spreadsheet with Python, AI (WASM and WebGL)
Hi, I am David Kircos. The Founder of Quadratic (https://QuadraticHQ.com), an open-source spreadsheet application that supports Python, SQL (coming soon), AI Prompts, and classic Formulas. Unlike other spreadsheets, Quadratic has an infinite canvas (like Figma). As a result, you can pinch and zoom to navigate large data sets, and everything renders smoothly at 60fps. Our vision is to build a place where your team can collaborate on data analysis. You can write Python, AI Prompts, and Formulas in one spreadsheet feeding each other data and updating automatically. Quadratic is built…

In plain words
Quadratic is an open-source spreadsheet application that combines Python, AI prompts, and traditional formulas in a single collaborative environment. It features an infinite canvas similar to Figma, allowing users to zoom and navigate large datasets smoothly at 60fps using WebGL and Rust WebAssembly technology. The platform is designed for teams performing data analysis, with cells that can reference and automatically update based on each other's outputs across different computation types.

Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
