Products that do what Captain, AI Travel Agent does
I’m a software designer from Lagos exploring conversational interfaces and frameworks for building agents. I made Captain to help with everyday travel planning. It can explore an itinerary, check live flight prices, or watch for the right time to book. Captain is a Telegram bot powered by a generalist model (anthropic/claude-sonnet-5), with specialist models handling workflows such as trip interpretation and voice transcription. It also includes a visual workspace where users can review the agent’s work and directly manipulate their travel information. I'm building the agent to explore…

Hi HN! We’re Arjun, Ramnique, and Akhilesh, and we are building Rowboat (https://www.rowboatlabs.com/), an AI-assisted IDE for building and managing multi-agent systems. You start with a single agent, then scale up to teams of agents that work together, use MCP tools, and improve over time - all through a chat-based copilot. Our repo is https://github.com/rowboatlabs/rowboat, docs are at https://docs.rowboatlabs.com/, and there’s a demo video here: https://youtu.be/YRTCw9UHRbU It’s becoming clear that real-world agentic systems…

I made this experimental art project/game that's an LLM chat assistant, but where you're the AI. I wanted people to get a visceral sense of what it's like to answer the kinds of things that people prompt their chatbots day in and day out. If you're interested, I wrote up some more info on how I made it, including how the "user" prompts are generated with an eye for realism: https://bethechatbot.com/about Hope you enjoy it! I'd love to hear people's takeaways.

Hi HN, my name is Maria, and I’m a co-founder of Maritime. We started Maritime at MIT to build infrastructure for companies that need to run thousands of isolated AI agents for their customers. Imagine you set up an agent like OpenClaw, or a personal assistant agent with a custom framework, and want to give a separate version of it to every customer/friend. Each customer needs their own agent running in an isolated microVM, with persistent state, secrets, triggers, and sleep/wake behavior. Building such scalable and secure infra will take you months and will cost hundreds of…

Hey HN! I got tired of AI agents being a pain to set up, impossible to customize without a PhD, and only viable if you're some Fortune 500 company. So I built something different, a chatbot you can literally drop onto your website with a single script tag. Create an account, add your domain, customize literally everything (theme, icon, welcome message, suggested responses, whatever), and you're done. The bot scrapes your site once a day to understand your business, or you can just upload docs-pricing sheets, policies, FAQs, you name it. That's your chatbot's brain right there. It only works…

This weekend I built a Minecraft bot for a server I play on. It uses the Agent SDK for the main loop and a bunch of custom MCP tools. Some highlights: * The bot is an active participant in the in-game chat, enabling all players to interact with it. * Tools for interacting with containers, crafting, trading with villagers and various other things. * Memory system which the agent uses to keep track of in-game events, interactions with players etc. * Screenshot tool which lets Claude use its vision modality to look around (not very useful, but fun). * Tooling for interacting with plugins…

Greetings Hacker News family! I'm excited to share with you the first version of our AI-powered travel planner. I'm a digital nomad/tech geek who loves traveling but admittedly am lazy about trip planning, so I created a tool built on ChatGPT that could help me jump start that. I simply enter a destination, the # of days, a budget preference, and it spits out a full travel itinerary with highlighted points of interest. The problem: Trip planning can be overwhelming and time consuming. While some may find excitement in planning, many folks are overwhelmed by the prospect of figuring out…

I'm Tyler - the solo operator of Quanta Intellect based in Portland, Oregon. I recently participated in Nous Research's Hermes Agent Hackathon, which is where this project was born. I've used agents extensively in my workflows for the better part of the last year - the biggest pain point was always the browser. Every tool out there assumes a human operator with automation bolted on. I wanted to flip that - make the agent the primary driver and give the human a supervisory role. Enter: Vessel Browser - an Electron-based browser with 40+ MCP-native tools, persistent sessions that survive…

Founder here. I built NEO, an AI agent designed specifically for AI and ML engineering workflows, after repeatedly hitting the same wall with existing tools: they work for short, linear tasks, but fall apart once workflows become long-running, stateful, and feedback-driven. In real ML work, you don’t just generate code and move on. You explore data, train models, evaluate results, adjust assumptions, rerun experiments, compare metrics, generate artifacts, and iterate; often over hours or days. Most modern coding agents already go beyond single prompts. They can plan steps, write files, run…

Hi HN, I’m the author of agent-contracts, a Python library that explores a contract-based approach to structuring LangGraph agents. When building larger LangGraph-based systems, I kept running into the same issues: - node responsibilities becoming implicit - state dependencies spreading across the graph - routing logic getting harder to reason about - refactoring feeling increasingly risky agent-contracts is an attempt to make these boundaries explicit. Each node declares a contract that describes: - which parts of the state it reads and writes - what external services it depends on - when…
