I Built a Local-First AI Chat App with Advanced RAG
I've built VT Chat, a privacy-first AI chat application that keeps all your conversations local while providing advanced research capabilities and access to 15+ AI models including Claude 4 Sonnet and Claude 4 Opus, O3, Gemini 2.5 Pro and DeepSeek R1. Live: https://vtchat.io.vn | Source: https://github.com/vinhnx/vtchat The core difference is true local-first architecture. All chats are stored in IndexedDB with zero server storage. Your API keys never leave your browser, and I can't see them even as the developer. You can switch between OpenAI, Anthropic, Google…

Axis OneNov 2025 · axis-one-psi.vercel.app · ▲78I’ve been building a small hardware box that runs local LLMs like Mistral, Qwen and Llama, and exposes an OpenAI compatible API on your local network. There’s no cloud, no login system and no telemetry. I built it because a lot of small firms want ChatGPTbstyle tools but can’t use cloud AI for privacy or compliance reasons, and most don’t want to deal with GPU servers, drivers, Docker or model configs. The aim is to make local AI feel as simple as plugging in a router. Right now the box boots into a very simple web UI where you choose a model and start using it. The API follows the OpenAI…
- IBI built an LLM chat app because we shouldn't need 10 AI subscriptions2025 · prismharmony.com · ▲58
I'm lost between ChatGPT vs Claude vs Gemini... which subscriptions to take? With Cursor and all these specific AI tools, I just wanted one simple chat app where I can use any model and pay only when I use it. Couldn't find one, so I built one. Pay only for what you use. Your prompts and docs, knowledge bases work with every model - no more copy-pasting between apps. Started as a personal project, but thought someone else might benefit from this too. https://prismharmony.com/chat What do you think?

Access Gemini Pro, Claude Pro, ChatGPT Pro models and more for $8/month. Is it another AI/LLMs wrapper? Yes. So why should I use it? Honestly right now there are a lot of other alternatives. But here's why I think it's useful enough to release it in early access: 1. Clear & transparent pricing model. Usage rates is the same is providers api rates + 10%. 2. LLMs responses don't rely on the client connectivity. We use Convex. It's super stable. You can even run multiple chats in parallel. 3. Use it if you like the design :) 4. We have a very clear roadmap. What's next? A desktop app…
AskAI by OrdemioNov 2025 · ordemio.com · ▲32Hi friends, I'm Dmitry, co-founder of Ordemio. I'd like to share with you what we have accomplished in 30 days of non-stop, 10-hour workdays. It was launched on August 1st, 2024. Is it good enough to attract our first customers? We have launched a new product in the highly competitive niche of "ChatGPT AI chatbot for a website," facing over 100 existing competitors on purpose. It's a gamble, and I'm unsure if it was the right decision. Feel free to ask any questions. Cheers.

Trickle - Magic Canvas ▲1,064Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
