Slate – Open-source AI workspace with a built-in browser

Hi HN,

I've been building Slate for the past few months and just open-sourced it. It's a native macOS app that puts AI chat and web browsing in the same window.

The idea came from how I actually use AI day to day. I'd ask Claude or GPT something, get a bunch of links or recommendations, then cmd-tab to a browser, open tabs, lose context, and go back and forth. It felt broken. I wanted the browser inside the AI conversation, not the other way around. So Slate is an AI workspace first, browser second. You ask a question, get a synthesized answer, click into sources right there in the same session, and keep asking follow-ups with full context. Each tab has its own conversation history.

A few things that might be interesting to this crowd:

- Native SwiftUI + WebKit, no Electron. Runs light on memory and battery on Mac. Downside: it's MacOS only, but it's the choice i took to create best possible UI and the user experience. - Most other "AI Browsers" bolt AI onto the chromium as an after-thought, but I wanted to build AI-first experience. - Supports Anthropic, OpenAI, Gemini, and Ollama for local models. Bring your own API keys. - Built-in content blocking, so pages load fast and clean. - Sessions group your tabs into workspaces you can archive and restore. - MIT licensed.

It's very much a v1. There's plenty I want to improve — extensions, better history, sync, AI Agents, MCPs, etc. — but the core loop of chat → browse → follow up feels solid enough to share.

Would love feedback, especially from anyone who's worked with WebKit or has opinions on how AI should integrate with browsing. Happy to answer questions about the architecture or anything else.
