Nimbus

In plain words

Nimbus is a desktop browser that integrates an AI agent as its primary interface. Rather than adding a chat feature to an existing browser, it redesigns the entire interface around an AI chat bar at the bottom, an agent activity log, and the webpage itself. The URL field becomes redundant when the browser understands user intent through conversational input. Available for macOS, Nimbus represents an experiment in reimagining browser fundamentals when AI agents drive navigation and interaction.

From the sources

Nimbus is an agentic browser inspired by Claude Code UX. Tell it what you want in plain English. It handles the mechanical work: clicks, forms, file pickers, multi-tab coordination and pauses to ask only when there's something only you can decide. Inspired by the way Claude Code feels for coding; built for the rest of the web. Built from the ground up, not an extension. Free for the first 500 founding users forever.

Nimbus is an AI-native browser companion that navigates, fills forms, and extracts data — so you can focus on decisions that matter.

In the maker’s words, at launch

Hi HN, I'm Anil. Nimbus is a desktop browser with an AI agent built into it. The UX is shamelessly inspired by Claude Code: a chat bar at the bottom, an agent log above it, and the webpage itself when its needed. This is mainly a UX experiment for me. And also the reason it isn't a Chrome extension: once you have a…

  Nxtscape – an open-source agentic browser2025 · github.com · ▲314

  Hi HN - we're Nithin and Nikhil, twin brothers and founders of nxtscape.ai (YC S24). We're building Nxtscape ("next-scape") - an open-source, agentic browser for the AI era. -- Why bother building a new browser? For the first time since Netscape was released in 1994, it feels like we can reimagine browsers from scratch for the age of AI agents. The web browser of tomorrow might not look like what we have today. We saw how tools like Cursor gave developers a 10x productivity boost, yet the browser—where everyone else spends their entire workday—hasn't fundamentally changed. And honestly, we…

  Hey HN! I built Browser AI after getting frustrated with the official Playwright MCP server in Claude Code. If you've used it, you know the pain: - 20+ separate tools that Claude has to juggle (click, fill, navigate, wait_for_selector, etc.) - Context window explosions from verbose screenshot data and DOM snapshots - Constant tool selection errors where Claude picks the wrong tool or forgets parameters Browser AI wraps Playwright MCP with a single natural language interface. Instead of Claude managing dozens of tools, you get one: browser_ai.execute. Just tell it what you want in plain…

  Hey Hackers! I've had this idea stuck in my head for a while: what if an AI could actually use my browser for me? I mean, not on some virtual machine in the cloud like ChatGPT agent, but right on my own browser. I finally decided to just build it and see what would happen. I wrote a quick MVP, and honestly, I didn't expect much. But then... it started doing things. On its own. It figured out how to use search engine to find what I needed, read a webpage to answer my questions, and even it can organize my chaotic mess of tabs into neat groups. It was a genuine "whoa" moment for me. That's…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
