Show HN: I got frustrated with SMILES, so I built onehttps://github.com/sangeet01/scriptHi HN, I'm an undergrad in Nepal.For the last 35 years, computational chemistry and AI drug discovery have relied on SMILES to represent molecules. It was great for the 1980s, but today it is a massive bottleneck. It’s non-canonical, its stereochemistry parsing is fragile, and it completely breaks down when trying to represent organometallics, alloys, or polymers. To parse it reliably, you basically need a 300MB C++ dependency (RDKit) relying on decades of hard-coded heuristics.I got frustrated and realized that representing matter isn't a graph theory problem—it’s a linguistics problem.To fix it, I built SCRIPT (Structural Chemical Representation in Plain Text). I based the core parser on the generative linguistics of Pāṇini’s Sanskrit grammar. Instead of treating a molecule as a string of dumb nodes, SCRIPT treats it as a language of Roots, States (Vibhakti), and Relationships (Sandhi).I just released V3 today for Pi Day.How it works & what it fixes: • Aromaticity without the mess: S

Show HN: PDR AI – Open-source startup accelerator engine for non-technical chaoshttps://github.com/Deodat-Lawson/LaunchStackShow HN: PDR AI – Open-source startup accelerator engine for non-technical chaos (marketing, PRDs, onboarding)A couple weeks ago I shared PDR AI as an open-source tool for startup doc mess[](https://news.ycombinator.com/item?id=47258661). Since then I've doubled down on the core vision: it's not just another RAG chat—it's an AI-powered accelerator engine that helps technical founders skip the non-technical pitfalls and move faster.As a solo technical founder, I wasted too much time on fragmented marketing plans, incomplete PRDs, onboarding docs, legal templates. PDR AI centralizes it all in a self-hostable knowledge base and actively accelerates progress by:- Document Sanity Chekcer (Verifying the content validity and consistency in the documents, extracing key information) - Marketing pipeline: Content ideas/trends for Reddit/X/LinkedIn/Bluesky, optional web-enriched analysis. - Team acceleration layer: Role-based access, invites, approvals, audit trails—great for small teams or accel

Volunteers Find Oddly High Solar Flare Rateshttps://science.nasa.gov/get-involved/citizen-science/volunteers-find-oddly-high-solar-flare-rates/Patches of the Sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions, we now know much more about the patches where these strong magnetic fields […]

Instagram Ending Encrypted DMshttps://news.ycombinator.com/item?id=47368081In May 2026, a technical change inside Instagram began to trigger a much larger debate about privacy, surveillance and the future of private conversations on the internet. The platform confirmed that it will discontinue end-to-end encryption for direct messages, reversing a feature that only a few years ago had been presented as a major step forward for digital privacy. What may sound like a technical adjustment to most users touches the center of a global conflict involving governments, technology companies and civil liberties.To understand why this matters, it helps to start with the basics. End-to-end encryption is a system that ensures only the sender and the recipient can read the content of a message. Not even the company operating the service can access it. In practical terms, it turns messaging apps into something close to a whispered conversation. Messages travel through servers but remain unreadable to any intermediary.For years, companies like Meta, Apple and Google defended

Show HN: Prompt optimizer that refactors messy prompts using a P-C-V pipelinehttps://how-to-grab-me.vercel.app/I built a small web tool that tries to automatically refactor messy prompts into structured prompt specifications.The motivation was simple: most prompts people write are poorly structured, which often leads to unstable AI responses.So I implemented a Proposer–Critic–Verifier optimization pipeline.Proposer restructures the prompt. Critic evaluates clarity, structure, and task definition. Verifier checks consistency. Arbiter detects convergence.The system runs several iterations and produces a structured prompt specification.It usually takes around 30–40 seconds to run the full optimization loop.The tool also includes: • prompt quality analysis • explain mode • version history • prompt diff viewerDemo: https://how-to-grab-me.vercel.app/Would love to hear if people building AI tools find something like this useful.

Launch HN: Spine Swarm (YC S23) – AI agents that collaborate on a visual canvashttps://www.getspine.ai/Hey HN! We're Ashwin and Akshay from Spine AI (https://www.getspine.ai). Spine Swarm is a multi-agent system that works on an infinite visual canvas to complete complex non-coding projects: competitive analysis, financial modeling, SEO audits, pitch decks, interactive prototypes, and more. Here's a video of it in action: https://www.youtube.com/watch?v=R_2-ggpZz0Q.We've been friends for over 13 years. We took our first ML course together at NTU, in a part of campus called North Spine, which is where the name comes from. We went through YC in S23 and have spent about 3 years building Spine across many product iterations.The core idea: chat is the wrong interface for complex AI work. It's a linear thread, and real projects aren't linear. Sure, you can ask a chatbot to reference the financial model from earlier in the thread, or run research and market sizing together, but you're trusting the model to juggle that context implicitly. There's no way to see how it's connecting the pieces, no
