Show HN: SergioAI – Trello bot with Claude that reviews PRDs and opens draft PRs

I built an open-source bot that turns Trello cards into working code using Claude Code.Drop a task card in a list → Sergio picks it up, explores your codebase, and posts an implementation plan as a comment. Add feedback, move the card back, and iterate. When you're happy, move it to the Development list → Sergio creates a worktree, writes the code, runs tests, and opens a draft PR on GitHub.It's a tool that can be used by teams of devs and product managers to cover the knowledge gaps b

Show HN: Finnish Humanizer – 26 patterns for detecting AI-generated Finnish text

Finnish is morphologically complex — vowel harmony, six grammatical cases, free word order. AI models get it wrong in the same predictable ways every time. I built this after noticing that AI-generated Finnish triggers immediate pattern recognition in native speakers: overly formal register, SVO word order (Finnish allows much more variation), missing discourse particles (-han/-hän, -pa/-pä), and excessive nominalization. Before: "Tämä on erittäin merkittävä kehitysaske

Show HN: The only CLI your AI agent will need

I started digging into OpenClaw, then found this: https://clawhub.ai/steipete/trello. They are literally telling people that it's okay to expose credentials, just as long as it's in an env var.If we’re building with AI, safety has to be a product principle, not an afterthought. AI makes coding more accessible, but it also strips away the guardrails you usually get from experienced mentors and hard-earned production lessons.So we built Earl: an AI-safe CLI for LLM ag

Show HN: Xpaper – A Chrome extension to turn your X feed into a newsletter

Hi HN,I built Xpaper (https://github.com/laiso/xpaper), an open-source Chrome extension that curates and summarizes your X (Twitter) timeline into a clean, readable newsletter format.Like many of you, I wanted to distance myself from the endless scrolling of Twitter, but completely quitting wasn't an option—I still needed to extract the signal from the noise. I built this to solve that exact dilemma.I took a specific technical approach that I thought HN might find intere

Show HN: A phone number you can call to talk to an AI that remembers you

I had a random thought a week ago: "why can't I just call my AI on the phone?"It spun into a series of thoughts:1. Phone calls are an established technology, people are used to picking up the phone and calling someone for a chat. It's much more natural than opening up a web app to talk2. Millions of people don't have access to reliable 4G/5G where they live but still have cell signal. Those people would probably still want access to an AI.3. Why don't I just bu

Show HN: Horizon – My AI-powered personal news aggregator and summarizer

Hi HN,I built Horizon because I was drowning in information overflow. I follow dozens of RSS feeds, subreddits, GitHub users, and, of course, HN itself. I found myself spends hours "doomscrolling" just to find the 3-4 things that actually mattered to my work and interests.Horizon is a personal intelligence agent that automates this. It doesn't just aggregate; it filters and enriches.How it works:Scrape: It pulls from GitHub (releases/events), Hacker News, Reddit, and any RSS

Show HN: Can you beat an AI at "being human" using one word?

I built TuringDuel, a Turing Test game where each move isjust one word. It's based on a research paper called "A Minimal Turing Test". You play human vs AI until one hits 4 points; an AI judge scores each round.I’m collecting data to benchmark different models as both players and judges (OpenAI / Anthropic / Gemini / Mistral / DeepSeek), but I only have ~45 games so far and need way more before publishing comparisons. (5 AI players and 4 judges at random gives

Show HN: goto-assistant – Self-hosted AI assistant, one npx command, no Docker

npx goto-assistant - that's it. Browser opens, an AI chat assistant walks you through setup (pick provider, paste API key, configure MCP servers), and you're done.I looked at OpenClaw's repo and was overwhelmed by the complexity. I just wanted a simple AI assistant I could understand end-to-end and run with one command. No framework, no build step for the frontend, no Docker, no always-on gateway.What it does:- Chat with Claude or OpenAI through a web UI- Task automation - create,

Ask HN: How do you track 2026 AI price wars? I built a tool to help

"I built https://tokencost.is to solve a recurring headache: manually scraping dozens of provider pages just to estimate API spend for my agentic workflows.My goal was a neutral, minimalist utility in the vein of Time.is. We now track 44 models—including OpenAI, Anthropic, Google, DeepSeek, Mistral, and Cohere—with hourly updates.Key Features:Real-Time Latency: We track TTFT benchmarks (e.g., Llama 3.1 at 28ms) alongside pricing.Price Deltas: We track 24h market shifts; look for t

Show HN: PaiperSwipe – Crowdsourcing AI summaries for 250M+ research papers

Put together a tool for quickly browsing and filtering the Openalex library of research papers. Would love to get some feedback on the system and it's utility for others, I've found myself using it almost like a social media in the past few days. Cheers!

Show HN: Aethene – Open-source AI memory layer

Hey 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

Show HN: Run 10 AI coding agents in parallel–each opens a PR when done

I built Paragent because I kept context-switching between features.The idea: describe what you want in plain English, and an agent branches off, writes the code, and opens a PR. You can run 10 at once — each on its own branch.How it works: - Connect your repo via GitHub App (minimal permissions: contents + PRs) - Describe a feature ("Add Stripe checkout to the pricing page") - Agent plans, writes, runs your verification, opens a PR - You review on GitHub like any other PRYou bring your

Show HN: ByePhone- An AI assistant to automate tedious phone calls

I have a bit of phone anxiety, and have a ton of dread around making phone calls to restaurants, banks, doctors, and so on and on.I thought: AI could do this with a web form turned into a prompt.Stack started out simple -> using 11labs for voice + claude + twillio, but it actually got rather complex (even though I tried vibe coding most).First off, finding the phone numbers quickly is hard. This is done by scraping the web with some basic duckduckgo search and structure with openai calls.Seco
