Show HN: Timezone converter that tells you if your meeting time sucks https://ift.tt/z2nkIK1

Show HN: Timezone converter that tells you if your meeting time sucks I work with a team spread across Sydney, London, and SF. Last month I accidentally called my Aussie colleague at 3am their time during what I thought was a "quick sync". The silence before "mate... do you know what time it is here?" still haunts me. Built this: https://timezig.com It's a timezone converter but it tells you if your meeting time sucks for the other person: - Meeting quality ratings (excellent/good/fair/poor) - Visual indicators for day/night - Shows if it's a holiday in their country - Handles weird cases like Dubai's Sunday-Thursday workweek Technical bit: pre-generated 18k+ static pages for every city combination. Loads instantly because there's no backend calculations. Next.js 15, no database. Still figuring out monetization (ads? affiliate links for virtual meeting tools?) but keeping it free for now. What else would make this useful? Currently tracking holidays for ~20 countries but could add more. https://timezig.com July 1, 2025 at 01:37AM

Show HN: C.O.R.E – Opensource, user owned, shareable memory for Claude, Cursor https://ift.tt/8pAEoDy

Show HN: C.O.R.E – Opensource, user owned, shareable memory for Claude, Cursor Hi HN, I keep running in the same problem of each AI app “remembers” me in its own silo. ChatGPT knows my project details, Cursor forgets them, Claude starts from zero… so I end up re-explaining myself dozens of times a day across these apps. The deeper problem 1. Not portable – context is vendor-locked; nothing travels across tools. 2. Not relational – most memory systems store only the latest fact (“sticky notes”) with no history or provenance. 3. Not yours – your AI memory is sensitive first-party data, yet you have no control over where it lives or how it’s queried. Demo video: https://youtu.be/iANZ32dnK60 Repo: https://ift.tt/A7MVfZw What we built - CORE (Context Oriented Relational Engine): An open source, shareable knowledge graph (your memory vault) that lets any LLM (ChatGPT, Cursor, Claude, SOL, etc.) share and query the same persistent context. - Temporal + relational: Every fact gets a full version history (who, when, why), and nothing is wiped out when you change it—just timestamped and retired. - Local-first or hosted: Run it offline in Docker, or use our hosted instance. You choose which memories sync and which stay private. Why this matters - Ask “What’s our roadmap now?” and “What was it last quarter?” — timeline and authorship are always preserved. - Change a preference (e.g. “I no longer use shadcn”) — assistants see both old and new memory, so no more stale facts or embarrassing hallucinations. - Every answer is traceable: hover a fact to see who/when/why it got there. Try it - Hosted free tier (HN launch): https://core.heysol.ai - Docs: https://ift.tt/Xtf0esY https://ift.tt/A7MVfZw July 1, 2025 at 01:10AM

Show HN: Audiopipe – Pipeline for audio diarization, denoising and transcription Audiopipe is a one-liner for denoising, diarization and transcription with demucs + pyannote + insanely-fast-whisper. Made it to transcribe podcasts and Dungeons And Dragons sessions, figured it could be useful. It also has a wasm UI to load transcriptions and audio. Feel free to contribute! Feedback appreciated. https://ift.tt/8SI5B9H June 30, 2025 at 11:32PM

Show HN: AI-powered tracker of Trump executive orders https://ift.tt/KNzOad4

Show HN: AI-powered tracker of Trump executive orders I built a tracker that automatically scrapes the White House website for new executive orders and uses GPT-4 to generate plain-English summaries. The system runs daily, finds new orders, feeds the full legal text to ChatGPT for summarization and auto-categorization, then generates individual pages and updates the main index. It even creates custom Open Graph images for social sharing. Currently tracking 158+ orders with automatic updates as new ones are signed. Features: - AI summaries of all executive orders in plain English - Auto-categorization by policy area (immigration, trade, AI, etc.) - Search by keyword, date, or category - Completely neutral - Individual pages for each order with full text - Auto-generated OG images I got tired of reading dense legal text to understand what's actually being signed. The AI does the heavy lifting of parsing government language into readable summaries.

Show HN: Ciara – Securely deploy any application on any server Hey HN! Coolify and Kamal were "nice" (Kamal docs are pretty bad, actually), but I still had to configure firewalls, unattended-upgrades, and Fail2ban every single time. Ciara does all of this from a single configuration file. Features: Integrated Firewall Automatic System Updates Zero-Config OS Ready Zero-Downtime Deployments Automatic HTTPS support Multiple Servers Deployments Would love your feedback and happy to answer any questions! https://ift.tt/8Vj0aSZ June 30, 2025 at 12:00AM
