Hello HN! I'm happy to release this project today. It's a bidirectional calculator (hence the name bidicalc). I've been obsessed with the idea of making a spreadsheet where you can update both inputs and outputs, instead of regular spreadsheets where you can only update inputs. Please let me know what you think! Especially if you find bugs or good example use cases.

A new calculator software cannot really bring attention (https://chachatelier.fr/chalk/) However, I wrote a full article explaining why I had to build something "new" that does not behave like usual desktop calculator softwares : TL;DR All "small" calculator softwares I know share the same design flaws. And the GUI is not the only stumbling block in their poor efficiency. Handling correctly numerical approximations - expected or not - is crucial to trust the results. It is usually not done in lightweight tools. It should. So I prove that if I could do it, OS manufacturers…

Hi HN, I’m an indie developer building Chemistry AI – a web-based chemistry solver for high-school and college students. Motivation: I saw many students searching for “chemistry AI” and mostly getting generic chatbots or math tools. I wanted something focused on chemistry that actually explains the steps, not just the final answer. What it does: - You can type a question or upload a photo of a worksheet. - The AI reads the problem and shows transparent, step-by-step reasoning. - It covers topics like equations, stoichiometry, acids/bases, equilibrium, thermodynamics, and basic organic…
