New Show Hacker News story: Show HN: I created a 2025 Wrapped for WhatsApp Conversations
Show HN: I created a 2025 Wrapped for WhatsApp Conversations
6 by nicolegrf9 | 1 comments on Hacker News.
Hey HN! As I sat to write my 2025 reflection, I realized one thing I was missing was a ‘year wrapped’ for my relationships — I got my music, got my photos, got my fitness wraps — but what about my relationships? Specifically, I wanted to figure out what my text conversations say about my relationships and myself, and if there’s been evolution throughout the year. Who reaches out more? What’s our tone and conflict resolution? What were our month by month successes and conflicts? So I built an app that analyzes WhatsApp conversations (.txt files) and surfaces the patterns — using Anthropic’s API for the AI-generated analysis and Instant as my database. It’s called Text Unwrapped. You sign up, and upload a conversation from WhatsApp. That’s sent to Anthropic's Claude AI with a bunch of different prompts. Here are some of the things you get: - Relationship score & synopsis on overall communication - Personality Profiles (Myers Briggs, tone analysis, top themes & emojis) - A month-by month timeline, outlining key texts and themes for that month - Actionable insights for each person - A deep dive on a topic of your choice (say you want to dive into defensiveness or avoidance) - POVs from different schools of psychology, like CBT and Jungian You can try this yourself. I made it so each sign up gets 1 free credit (1 credit = 1 conversation analysis). I am not a technical person: I vibe-coded this. I used Claude Code (Opus 4.5), and Instant as the backend. I’ve been playing around with making apps for the last few years, but it was always hard to make a leap. As of this March, I was able to start turning a lot of my passion projects into real ideas. I’ve made a few personal apps, but this is the first one I wanted to share on HN. It took me about 3 days to build this. Once I had a strong spec in place, I needed to make very little changes to Claude (mainly upgraded the design and double checked permissions). Outside of that, Instant was a big help: Claude was able to use it and add auth in less than 2 minutes. The hardest part was adding Stripe - but mainly because I hadn’t done this before. Claude Code guided me through the Webhook setup, and the main challenge was listening to the ‘checkout complete’ to validate payment and add credits to the user. I know privacy is a big concern here. For what it’s worth, I don’t store the actual conversation file — it’s deleted as soon as the conversation analysis is completed. I only store the analysis in the database. Hope you enjoy it!

New Show Hacker News story: Show HN: Stop Claude Code from forgetting everything
Show HN: Stop Claude Code from forgetting everything
24 by austinbaggio | 18 comments on Hacker News.
I got tired of Claude Code forgetting all my context every time I open a new session: set-up decisions, how I like my margins, decision history. etc. We built a shared memory layer you can drop in as a Claude Code Skill. It’s basically a tiny memory DB with recall that remembers your sessions. Not magic. Not AGI. Just state. Install in Claude Code: /plugin marketplace add https://ift.tt/rkI2zM8 /plugin install ensue-memory # restart Claude Code What it does: (1) persists context between sessions (2) semantic & temportal search (not just string grep). Basically git for your Claude brain What it doesn’t do: - it won’t read your mind - it’s alpha; it might break if you throw a couch at it Repo: https://ift.tt/rkI2zM8 If you try it and it sucks, tell me why so I can fix it. Don't be kind, tia

Show HN: Shardium – open-source "Dead Man's Switch" for crypto inheritance
2 by maxcomperatore | 0 comments on Hacker News.
Hi HN, I'm Max. I built this because I was terrified that if I die tomorrow, my family gets nothing. The existing solutions were either trusting a centralized custodian or complex hardware setups. Shardium is a client-side tool that splits your seed phrase into 3 shards using Shamir's Secret Sharing. Shard A: You keep. Shard B: You give to a beneficiary (PDF). Shard C: We hold (or you self-host). It works as a dead man's switch: If you are inactive for 90 days (email ping), Shard C is released to your beneficiary. They combine B + C to recover the funds. The Stack: secrets.js-grempe for the math. FastAPI + PostgreSQL backend. Client-side encryption (seed never hits the network). It is 100% Open Source and MIT Licensed. You can self-host it for free ($0), or use the managed version. I'd love your feedback on the security model. Roast my code here: https://ift.tt/dYZfVUD

New Show Hacker News story: Show HN: Golazo – Live soccer updates in your terminal
Show HN: Golazo – Live soccer updates in your terminal
2 by rocajuanma | 0 comments on Hacker News.
Hey all! I built Golazo because I wanted a minimal but effective way to get soccer live updates and catch up on finished matches right in my terminal. No browser tabs, no ads, no distractions: just clean match data where I already spend most of my day. I couldn’t find any actively maintained tool like this, so I thought it could be cool to build something just for what I need. It was a great learning experience and if it’s useful to other people, then even better! Current features: - Live match tracking with real-time score updates (90-second polling intervals) - Minute-by-minute match events (goals, cards, substitutions) - Finished match statistics and full event history - Goal notifications via beeep (macOS, Linux, Windows) - 40+ leagues supported (and growing) with customizable preferences to limit what you fetch - Smart caching: data cached for 5 minutes, polling only when viewing live matches Technical details: - Built with Go using Cobra for CLI, Charm’s Bubble Tea/Bubbles/Lip Gloss for the TUI - Data from a trimmed-down version of the Fotmob API - Cross-platform terminal rendering has been the biggest challenge – still working through some rough edges Easy to install via install script or build from source. Pre-built binaries available for macOS, Windows, and Linux. Would love to hear feedback from fellow terminal enthusiasts and soccer fans!

Show HN: Upload a song and get a finished music video (no editing, no prompts)
2 by hexadecimal | 1 comments on Hacker News.
I built a small web tool that generates finished music videos from uploaded songs. Most AI video workflows I tried required prompting scenes, generating clips, and editing everything on a timeline. I wanted the opposite: upload a track, pick a style, and get a video out in minutes. It’s intentionally opinionated: no accounts, no subscriptions, and no editing controls. One-time payment per video ($2–$12), and you own the output. I’d love feedback on whether this feels useful or too limiting.
