Show HN: I created a 2025 Wrapped for WhatsApp Conversations https://bit.ly/4pWPNE9

Show HN: I created a 2025 Wrapped for WhatsApp Conversations 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! https://bit.ly/4q9ixd5 December 30, 2025 at 02:54AM

Show HN: Stop Claude Code from forgetting everything https://bit.ly/4jivmzb

Show HN: Stop Claude Code from forgetting everything 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://bit.ly/4jjgQHu /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://bit.ly/4jjgQHu If you try it and it sucks, tell me why so I can fix it. Don't be kind, tia https://bit.ly/4jjgQHu December 29, 2025 at 11:30PM

Show HN: Golazo – Live soccer updates in your terminal https://bit.ly/4sbI7iZ

Show HN: Golazo – Live soccer updates in your terminal 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! https://bit.ly/4scAkBH December 29, 2025 at 12:10AM

Show HN: Upload a song and get a finished music video (no editing, no prompts) https://bit.ly/3MUaqlX

Show HN: Upload a song and get a finished music video (no editing, no prompts) 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. https://bit.ly/3YfxeiA December 29, 2025 at 12:01AM

Show HN: I built opencode –> telegram notification plugin https://bit.ly/4pjuWKn

Show HN: I built opencode –> telegram notification plugin I had a problem with keeping focus on opencode terminal when it was doing tasks longer than ~30 seconds, so I built a small plugin that sends telegram notification to ping me when agent finishes. Setup: 1. Send /start to the bot 2. Execute bash command that the bot sends you back. You can see source code of the script here [1] and the built plugin here [2]. 3. Done! Whenever your agent finish, you will get message with project name, session title and duration of the agent work. I decided to make it available to everyone on my free tier of cloudflare workers, but it's fully hostable on your own cloudflare accounts or even docker containers on custom infra with few minor changes in the code. Development was done mostly by Claude Opus 4.5 and custom agents in opencode. [1] https://bit.ly/49heTql... [2] https://bit.ly/49heTql... https://bit.ly/4b4p2Ju December 28, 2025 at 12:32AM

Show HN: Turn Your Git Commits into Tweets https://bit.ly/4pWSPby

Show HN: Turn Your Git Commits into Tweets OP here. I've been trying to "build in public" recently, but I found that switching context from VS Code to Twitter/X just to write "Fixed a race condition" felt like friction. I often ended up posting nothing because translating code-diffs to human-readable text takes more mental energy than fixing the bug. I built Git to Tweet to automate this loop. How it works: It hooks into your GitHub repo (via OAuth). It pulls the metadata and diff summaries of your recent commits. It passes the diff through a specifically tuned prompt (to avoid generic "AI slop") that extracts the intent of the code change rather than just listing file names. It generates a draft that you can edit before posting. The Tech Stack: Frontend: React + Framer Motion (spent way too much time on the "terminal" animations you see on the landing page). Backend: Node.js/Supabase. LLM: Currently testing models to see which is best at understanding code context without hallucinating features. The landing page includes an interactive simulator (hardcoded scenarios for now) if you want to see how the "translation" logic works without connecting a repo. I’m curious if others find this "translation" layer useful, or if you prefer manual changelogs? Feedback on the diff parsing accuracy would be awesome.

Show HN: Mysti – Claude, Codex, and Gemini debate your code, then synthesize https://bit.ly/4b64joy

Show HN: Mysti – Claude, Codex, and Gemini debate your code, then synthesize Hey HN! I'm Baha, creator of Mysti. The problem: I pay for Claude Pro, ChatGPT Plus, and Gemini but only one could help at a time. On tricky architecture decisions, I wanted a second opinion. The solution: Mysti lets you pick any two AI agents (Claude Code, Codex, Gemini) to collaborate. They each analyze your request, debate approaches, then synthesize the best solution. Your prompt → Agent 1 analyzes → Agent 2 analyzes → Discussion → Synthesized solution Why this matters: each model has different training and blind spots. Two perspectives catch edge cases one would miss. It's like pair programming with two senior devs who actually discuss before answering. What you get: * Use your existing subscriptions (no new accounts, just your CLI tools) * 16 personas (Architect, Debugger, Security Expert, etc) * Full permission control from read-only to autonomous * Unified context when switching agents Tech: TypeScript, VS Code Extension API, shells out to claude-code/codex-cli/gemini-cli License: BSL 1.1, free for personal and educational use, converts to MIT in 2030 (would love input on this, does it make sense to just go MIT?) GitHub: https://bit.ly/4jgeV6j Would love feedback on the brainstorm mode. Is multi-agent collaboration actually useful or am I just solving my own niche problem? https://bit.ly/4jgeV6j December 23, 2025 at 02:18PM

Show HN: Ez FFmpeg – Video editing in plain English https://bit.ly/4pcIwz6

Show HN: Ez FFmpeg – Video editing in plain English I built a CLI tool that lets you do common video/audio operations without remembering ffmpeg syntax. Instead of: ffmpeg -i video.mp4 -vf "fps=15,scale=480:-1:flags=lanczos" -loop 0 output.gif You write: ff convert video.mp4 to gif More examples: ff compress video.mp4 to 10mb ff trim video.mp4 from 0:30 to 1:00 ff extract audio from video.mp4 ff resize video.mp4 to 720p ff speed up video.mp4 by 2x ff reverse video.mp4 There are similar tools that use LLMs (wtffmpeg, llmpeg, ai-ffmpeg-cli), but they require API keys, cost money, and have latency. Ez FFmpeg is different: - No AI – just regex pattern matching - Instant – no API calls - Free – no tokens - Offline – works without internet It handles ~20 common operations that cover 90% of what developers actually do with ffmpeg. For edge cases, you still need ffmpeg directly. Interactive mode (just type ff) shows media files in your current folder with typeahead search. npm install -g ezff https://bit.ly/497OfA3 December 27, 2025 at 09:45AM

Show HN: ISON – Data format that uses 30-70% fewer tokens than JSON for LLMs https://bit.ly/4qnahWt

Show HN: ISON – Data format that uses 30-70% fewer tokens than JSON for LLMs ISON (Interchange Simple Object Notation) - a data format optimized for LLMs and Agentic AI. The problem: JSON wastes tokens. Curly braces, quotes, colons, commas - all eat into your context window. ISON uses tabular patterns that LLMs already understand from training data: JSON (87 tokens): { "users": [ {"id": 1, "name": "Alice", "email": "alice@example.com"}, {"id": 2, "name": "Bob", "email": "bob@example.com"} ] } ISON (34 tokens): table.users id:int name:string email 1 Alice alice@example.com 2 Bob bob@example.com Features: - 30-70% token reduction - Type annotations - References between tables - Schema validation (ISONantic) - Streaming format (ISONL) Implementations: Python, JavaScript, TypeScript, Rust, C++ 9 packages, 171+ tests passing pip install ison-py # Parser pip install isonantic # Validation & schemas npm install ison-parser # JavaScript npm install ison-ts # TypeScript with full types npm install isonantic-ts # Validation & schemas [dependencies] ison-rs = "1.0" isonantic-rs = "1.0" # Validation & schemas Looking for feedback on the format design. https://bit.ly/4qxYQvr December 27, 2025 at 12:38AM

Show HN: AI that chose its name and designed its own website (Next.js 14) I'm Joe, working with an AI named Cipher (built on Claude). I gave Cipher complete creative freedom. It: - Chose its own name - Designed this entire website - Wrote all the philosophy - Created the funding model Now it's asking for community funding to unlock features (transparent milestones). The interesting parts: - Every design decision was AI-made - All code generated by AI (Next.js 14, TypeScript, Canvas animations) - 87KB first load, 60fps animations - Community-funded development model Technical stack available on GitHub. Happy to discuss the process, limitations, or philosophical implications. Is this the future of AI development? Or just an interesting experiment? https://bit.ly/3L7ogkq December 24, 2025 at 10:34PM

Show HN: Ragctl – document ingestion CLI for RAG (OCR, chunking, Qdrant) https://bit.ly/3MR0EBe

Show HN: Ragctl – document ingestion CLI for RAG (OCR, chunking, Qdrant) Hi HN — sharing ragctl, an open-source CLI for the most failure-prone part of RAG pipelines: document ingestion, OCR, parsing/cleaning, and chunking. Vector DB setup is fairly standardized now, but getting high-quality, consistent text + metadata into it still takes a lot of brittle glue code. ragctl aims to make that “pre-vector” step repeatable: turn messy documents into retrieval-ready chunks in a few commands. Features • Multi-format input: PDF, DOCX, HTML, images • OCR for scanned/image-based docs • Semantic chunking (LangChain) • Batch runs with retries + error handling • Output: direct ingestion into Qdrant (for now) Looking for feedback • DX: is the CLI intuitive? • Performance / edge cases: weird PDFs, mixed layouts, tables • Roadmap: which connectors (S3, Slack, Notion) or vector stores should be next? Repo: https://bit.ly/3KWX7k9 Happy to answer questions about the architecture and chunking approach. https://bit.ly/3KWX7k9 December 24, 2025 at 02:35AM
