Show HN: Lingle – Voice agent to simulate zoom-based personal language lessonshttps://lingle.ai/In my opinion the best way to learn a language (outside of moving to a different country) is to get a personal tutor and have consistent 1 on 1 lessons. I used Preply or iTalki for this back in the day but had issues with flexibility and pricing.I've been trying to simulate the experiences that I had on those platforms with a voice agent.You can try a demo for free here (or watch a video of me using it on the landing page):https://lingle.ai/tryout/lingle-showcaseRight now the agent can plan a lesson with visuals and a conversation focus, guides the user through the lesson - correcting and explaining things on a whiteboard if necessary, and asks relatively engaging questions. There is also a long term user model that builds over time, that maintains memory of the user's produced vocabulary, grammar, and skills, meant to make each lesson informed by the past and build on the user's knowledge (obviously this is still relatively fragile in practice).The voice agent itself has actually deceApr 9, 2026 10:28 PM

Show HN: A platform to help you find the best tech jobshttps://thedream.work/Hey everyone,Long time lurker finally took the leap to share something with the community.From a long time I wanted to build something and I had this idea about a job board but not just a simple aggregator or just a job board. Basically I don't like any of the existing websites for jobs and most of the job boards are just aggregators that you constantly get redirected to third party links not the best experience. I also don't have the best experience with recruiters been ghosted, conversation looping in meaningless question and so on.And the current job market is kind of disheartening non existing entry level jobs pretty brutal stuff.The idea of the platform is to an extent to be fully autonomous in terms of you as user not browsing jobs but you automatically get matched with opportunities. Also companies looking for talent will have the same ability to view the people who are best matches. One of the main aspects is to basically to get a really good starter conversation between the coApr 1, 2026 5:01 PM

Show HN: Memv – Memory for AI Agentshttps://github.com/vstorm-co/memvmemv is an open-source Python library that gives AI agents persistent memory. Feed it conversations; it extracts knowledge.The extraction mechanism is predict-calibrate (Nemori paper): given existing knowledge, it predicts what a new conversation should contain, then extracts only what the prediction missed.v0.1.2 adds the production path: - PostgreSQL backend (pgvector for vectors, tsvector for text search, asyncpg pooling). Single db_url parameter — file path for SQLite, connection string for Postgres. - Embedding adapters: OpenAI, Voyage, Cohere, fastembed (local ONNX).Other things it does: - Bi-temporal validity: event time (when was the fact true) + transaction time (when did we learn it), following Graphiti's model. - Hybrid retrieval: vector similarity + BM25 merged with Reciprocal Rank Fusion. - Episode segmentation: groups messages before extraction. - Contradiction handling: new facts invalidate old ones, with full audit trail.Procedural memory (agents learning from past runsMar 30, 2026 5:09 PM

Abacus Agentic Behaviorhttps://news.ycombinator.com/item?id=47568594Deep agent is wonderful. It has helped our company immensely in numerous ways. The flow was always great.. helpful.Now, however, enshittification by way of "useful" developmental changes have become a pain in the ass.Working with their Deep Agent has recently become onerous.Any time it "thinks" you are deviating from the agentic flow, it pops up an intrusive modal stating:"Do you want to continue? This query does not seem to be related to previous turn queries. Are you sure you want to continue in the current conversation?For optimal and cost-effective performance we recommend starting a new conversation with this prompt."This breaks the flow considerably when I have to take myself out of my moment to address your apparent lack of insight that not everything in a flow is going to be related to the session.

Show HN: Kora – An AI-native OS layer written in 370k lines of Rusthttps://intuitivecompute.comWe've been building this for ourselves over the last year. We wanted the computer from Star Trek, something you just talk to, that knows your context, controls your environment, and runs locally.Our core belief is digital sovereignty in that you should own your context. Your conversations, files, voice, memory, and identity never leave your machine unless you explicitly choose to route through a cloud provider. No telemetry, no accounts, no data collection. The AI that knows the most about you should be the one you control completely.Kora is an operating system layer built around an AI agent. On Linux it runs as the GUI directly in Wayland (OpenGL via femtovg). On macOS it's a native app with a Metal compositor.It's not a chatbot wrapper, it's closer to a full OS where the AI is a first-class service. The stack is ~8 services running locally:- UI: custom window manager with guest app compositing.

Show HN: PingCRM – Open-source personal networking CRMhttps://github.com/sneg55/pingcrmHey HN,Robin Dunbar figured the human brain caps out at roughly 150 stable relationships. After that, people just fall off. Not because you stop caring, but because you can't track that many threads at once. I built PingCRM to push past that limit, not by making you remember more, but by handling the part you're bad at: noticing who's going cold and drafting something worth sending.CRMs exist, but they're built for sales teams. I wanted something for one person maintaining their own network. Specifically:(1) Pull in conversations I'm already having. Gmail threads, Telegram DMs, Twitter DMs, LinkedIn messages, no manual logging.(2) Tell me who's going cold. A relationship score (0–10) based on recency, frequency, reciprocity, and breadth of interaction.(3) Draft the message for me. Claude reads your conversation history, picks the right tone (formal vs. casual), and writes a follow-up that references why now is a good time, like a job change, a long silence, or a fundraising announcemenMar 18, 2026 10:33 AM

The Quiet Normalization of Artificial Intelligencehttps://news.ycombinator.com/item?id=47401303Over the past few years, it has become almost routine to hear warnings about artificial intelligence. Headlines often focus on the risks. Job displacement, algorithmic manipulation, surveillance, loss of control over autonomous systems. In public debates, AI frequently appears as a looming threat, something powerful and unpredictable that could reshape society in dangerous ways.Yet at the very same time that these fears dominate the conversation, something quieter has been unfolding. Millions of people have already woven artificial intelligence into their daily routines. They rely on algorithms to help write emails, ask digital assistants for research guidance, receive recommendations about what to watch or read, and use AI-powered tools to accelerate their work. The criticism grows louder, but the habit grows stronger.The data reveals a striking contradiction. A global study involving tens of thousands of participants found that around 66 percent of people worldwide already use artifiMar 16, 2026 4:40 PM

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 defendedMar 13, 2026 6:46 PM

Show HN: FirstVibe – AI analyzes your selfie and scores your vibe in 30 secondshttps://firstvibe.app/FirstVibe is an AI selfie analyzer that gives you a "vibe check" -- a personality and impression analysis based on your photo. Upload a selfie and get an overall score, personality label, 5 category scores (attractiveness, confidence, charisma, style, approachability), celebrity lookalike, aura type, dating energy, and a set of fun predictions and personalized improvement tips.It uses Claude's Vision API to read facial expressions, body language, styling choices, and overall energy from the photo. The difference from typical face-rating apps is that it focuses on personality and vibe rather than bone structure or symmetry (though it does golden ratio and face shape analysis too). The AI analyzes things like approachability, confidence level, conversation style, and what kind of first impression you make.Technical details: Rails 8, Hotwire/Turbo for real-time result streaming, PostgreSQL with JSONB for flexible AI output storage, Solid Queue for background jobs.

What you actually need depends on your age, sex, family history, smoking status, and other factors. Most people, including me until recently, simply don't know what they should be getting checked for.I built FixYou after losing my grandfather to colon cancer that was caught too late. After his diagnosis, my parents went for colonoscopies and found polyps, early and treatable. We didn't lack access to healthcare. We lacked clarity.FixYou is a free tool that: 1. Walks you through a short AI conversation about your health profile 2. Cross-references your answers against current USPSTF and ACS screening guidelines 3. Gives you a "Shield Score" (0 to 100) and a prioritized list of screenings to scheduleThe goal isn't to replace your doctor.

Launch HN: TeamOut (YC W22) – AI agent for planning company retreatshttps://app.teamout.com/aiHi HN, I’m Vincent, CTO of TeamOut (https://www.teamout.com/). We build an AI agent that plans company events from start to finish entirely through conversation. Similar to how Lovable helps build websites through chat, we apply that approach to event planning. Our system handles venue sourcing, vendor coordination, flight cost estimation, itinerary building, and overall project management.Here’s a demo: https://www.youtube.com/watch?v=QVyc-x-isjI. The product is live at https://app.teamout.com/ai and does not require signup.We went through YC in 2022 but did not launch on HN at the time. Back then, the product was more traditional, closer to an Airbnb-style search marketplace. Over the past two years, after helping organize more than 1,200 events, we rebuilt the core system around an agent architecture that directly manages the planning process. With this new version live, it felt like the right moment to share it here since it represents a fundamentally different approach to planningFeb 25, 2026 2:02 PM

Show HN: Aethene – Open-source AI memory layerhttps://github.com/akhilponnada/aetheneHey HN, I'm shipping my first open-source project and I'm pretty nervous about it. Aethene is an AI memory API – it gives your AI apps persistent memory. Store conversations, extract facts automatically, search semantically, handle contradictions gracefully. It works well thank most of the memory projects available on the market currently.Why I built this: I was building AI agents and kept running into the same problem – they forget everything. Every conversation starts from zero. I wanted something that could: - Auto-extract facts from conversations (not just store raw text) - Handle "user moved from SF to NYC" without keeping both as true - Search by meaning, not just keywords - Version everything (who said what, when) Tech stack: - TypeScript + Hono (fast, edge-ready) - Convex (real-time DB + vector search) - Gemini (embeddings + extraction) What it does: # Store memory curl -X POST /v1/content -d '{"content": "User loves hiking, lives in SF"}' # Recall naturally curl -X POST /v1/reFeb 22, 2026 1:57 PM

Show HN: Pickle Rick Ported to Claude Code – Like a Ralph Loophttps://github.com/gregorydickson/pickle-rick-claudeThis is a port of the Pickle Rick Gemini CLI extension (itself an implementation of Geoffrey Huntley's "Ralph Wiggum" technique) for Claude Code, with one meaningful enhancement: context clearing between iterations. The core idea: a Claude Code Stop hook intercepts every session exit and blocks it, injecting a fresh prompt instead. Claude never actually stops — it just keeps working through a rigid lifecycle (PRD → ticket breakdown → per-ticket research/plan/implement/refactor) until the task is genuinely complete or a limit is hit. The problem with long loops: Claude Code compresses old conversation turns as context fills up. After enough iterations, the agent loses track of what phase it's in, which tickets are done, and what it was supposed to be building. It starts restarting from scratch. The fix: every decision: block response from the Stop hook includes a reason field with a structured session summary — current phase, iteration count, ticket checklist with status, original task,Feb 20, 2026 5:54 PM

Behind the façade of casual chat and video call services lies an organized structure of recruitment, monetization, and alleged violations of personal privacy affecting users worldwide.Evidence suggests that owners of chat applications such as 1vs1 Chat, TopChat, and Mixu subcontract intermediary agencies that recruit women, primarily from South America, to work as virtual operators. Their role is to engage clients in private conversations and intimate video calls billed by the minute. While the commercial nature of these interactions is clear, what happens outside the official platforms raises serious ethical and legal concerns.According to collected testimonies, many operators particFeb 13, 2026 4:14 PM
