Chatbots and GPT-3: Using human knowledge and relevant context for better chatbot experiences

GPT, or Generative Pre-trained Transformer, is an autoregressive language model that uses deep learning to produce human-like texts. GPT-3 is the third generation of the GPT series launched by OpenAI, ...

Show HN: Gcommit – clustering code changes semantically

The problem: I kept making "mega-commits" with unrelated changes because I get in a flow state and then end up with a huge number of changes I forgot to commit.The solution: I built a tool that analyzes your staged git changes, clusters them by semantic similarity using embeddings + hierarchical clustering, and creates separate commits for each cluster.How it works:- Parses diffs into semantic chunks using tree-sitter- Generates embeddings (OpenAI text-embedding-3-small)- Clusters with

Show HN: LLM-powered data extraction from messy spreadsheets

Uses an LLM to identify where tables actually start&#x2F;end in Excel&#x2F;CSV files, then extracts clean, typed data.<p>Handles all the messy formatting (currency, percentages, different number formats) and streams efficiently for large files.<p>Works with OpenAI, DeepSeek, or any compatible API.

Ask HN: What are your biggest challenges raising capital pre-revenue?

Raising capital pre-revenue is pretty difficult for most people. I realize that everyone&#x27;s not having the same difficulties.<p>I&#x27;m opening up a feedback loop to get a better insight on the experiences founders are having.

I built a one-hotkey inline AI rewriting tool (and what went wrong)

I’ve been dogfooding a small writing helper I built called Rephrazo, and I thought it might be useful to share some implementation details and mistakes so far.The idea is simple: - highlight text where you’re writing - press a hotkey - get an AI paraphrase in a small popup - insert it back with one click The goal is to remove the “copy - open AI tool - paste - rewrite - paste back” loop for small edits.This post is about how I wired it up, what worked technically, and what didn’t.Constra

Show HN: mdfocus – A distraction free Markdown reader for your localhost

LLMs generate a lot of Markdown—Claude exports, ChatGPT conversation dumps, research notes, wiki-style docs.I found myself constantly opening these in VS Code or converting them just to read comfortably.So I built mdfocus: a zero-config local reader that you point at any folder and start reading instantly (npx mdfocus ~&#x2F;notes).It&#x27;s not a static site generator or a publishing tool—just a clean, focused way to consume Markdown locally.Includes live-reload, auto-generated table of content

Show HN: Control Your Telegram with AI

I put together a small side project that lets me use AI to work with my own Telegram account — searching chats, summarizing long threads, and sending messages without opening the app.It’s not a product or a framework. I mostly built it because I’m in a lot of noisy Telegram groups and wanted a better way to answer questions like “what did we decide last week?” or “did anyone mention X recently?”The setup uses a Model Context Protocol (MCP) server that connects Telegram to AI clients like Claude

OpenAI Launches GPT-5.2 for ChatGPT Users a Week After Declaring 'Code Red'

Just a month after introducing GPT 5.1, OpenAI introduced GPT-5.2, the next-generation model that will power its popular chatbot. GPT-5.2 is OpenAI's "most capable model series yet for professional knowledge work". GPT-5.2 is designed to help people get more done quicker. It's better at creating spreadsheets, building presentations, writing code, perceiving images, understanding long context, using tools, and completing multi-step projects.

ChatGPT's GPT-5.2 is here, and it feels rushed

GPT-5.2 is now live for all ChatGPT users with improved coding, writing and image interpretation, with Kurt Knutsson offering ...

I tested the new GPT-5.2—it just can't compete with Google Gemini 3

Despite OpenAI's bold claims of widespread improvements, GPT-5.2 feels largely the same as the model it replaces. Google, ...

Anthropic launches new version of scaled-down ‘Haiku’ model

On Wednesday, Anthropic released Claude Haiku 4.5, the newest version of its smallest model, billed as offering similar performance to Sonnet 4 “at one-third the cost and more than twice the speed,” ...

Anthropic takes the fight to OpenAI with open standard enterprise AI tools

Show HN: PocketCheck – A checklist for things not worth writing down

I have ADHD tendencies. I leave things half-done, go home with my work keys still in my pocket, and as soon as I start something else I completely forget the task I was doing before. Reminders don’t work — I just don’t look at them. Checklists don’t work either — I forget to check them in the first place. So I built PocketCheck. It periodically asks, “Anything to put in your pocket?” It’s a pocket that stands in for my working memory. I forget what I put in my actual pockets all the time, but th

Google Bard’s Latest Update Enhances Understanding Of YouTube Videos

Google Bard expands its capabilities with YouTube video understanding. I put this new feature to the test – does it live up to expectations? Google introduces an enhancement to Bard's AI, enabling it ...

Show HN: Tessera Designer – Generate beautiful, seamless patterns

Hey,A few weeks ago I randomly decided to build a seamless pattern engine for Swift&#x2F;SwiftUI projects. I called it Tessera (GitHub link). It’s an open-source framework that lets you generate endlessly repeatable, seam-free patterns from pretty much anything you can build in code: shapes, SF Symbols, emojis, text, custom icons, etc.While working on it, I also built a demo app so developers could see how to use the framework. However, that demo turned out to be so much fun to play with that I

Show HN: Claude Code in Cursor

Simple proxy service that uses your oauth credentials from Claude Code which you can pop into Cursor and use.<p>Falls back to your API key if you have one set.<p>I spent $XXXX on Cursor on Anthropic API Credits, but was told that the Claude Code $200 pmo plan was much more affordable. It&#x27;s a great arbitrage, so I made this hack so I could save money on this.<p>Note: Cursor OpenAI baseurl overriding is <i>extremely</i> buggy right now so I don&#x27;t recommend trying this for now.

Show HN: Chaos engineering for LLMs – Making models cross-examine each other

Single-model inference is a single point of failure. I got sick of Chatgpt hallucinating fake citations and having to manually check them in a different tab with Claude.So I built CouncilThe Difference: Shared Context Most &quot;multi-bot&quot; UIs are just parallel silos. Council uses a sequential backend stream where every response is injected into the context of the next model.If GPT cites a fake study, Claude sees it and calls it out.If Gemini misses a logic gap, Grok roasts it.Adversarial L

Show HN: Agentica – 200 reqs/day for free, data not used to train our LLMs

I built an extension that gives developers cheaper access to AI models in a Kilo Code fork.Free tier: 200 requests&#x2F;day to open source models (DeepSeek, Qwen, Minimax) Paid tier ($20&#x2F;month): $45 in credits for Claude&#x2F;GPT-5&#x2F;Gemini-3 + 1000 daily open source requestsWorks in VS Code, Cursor, and Windsurf.

Ask HN: How to gain a solid understanding of IMUs?

My background is primarily software (Python, AI&#x2F;ML, large-scale data). This is my first serious hardware-heavy product.I’m working on a company concept that depends on embedded IMUs, and I’m trying to front-load learning so I don’t lock myself into poor architectural, software or component decisions early on, especially those pitfalls that someone with more knowledge&#x2F;expertise would know how to avoid.I understand “learning by doing” is essential, but I suspect there are canonical pitfa
