Neurooo – DeepL clone using LLMs for translations
Hi HN, We built Neurooo.com, an automatic translation tool like DeepL or Google Translate, but using LLMs with OpenAI and Mistral. We noticed that LLMs were quite good at translating informal or contextual text, and also way cheaper than DeepL or Google Translate when you factor in the cost per character. So we decided to try and build a similar translation interface to see if we can match the leaders in term of ease of use and quality. We're quite happy about it and people around us seem to think that we're even better in many cases (abbreviations, informal emails, business translations,…
In plain words
Neurooo is an automatic translation tool that uses large language models from OpenAI and Mistral instead of traditional machine translation systems. It offers a similar interface to DeepL and Google Translate but operates at lower cost per character. The service is designed for users who need to translate informal, contextual, or business text, including abbreviations and casual emails, with builders claiming it matches or exceeds established translation services in quality and ease of use.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
