BrowserOS - v0.43.0

✨ What's new:

Skills — Define reusable instructions that teach your agent how to handle specific tasks. Ships with 12 built-in skills like deep research, price comparison, and form filling — and you can create your own. Docs →

Memory — Your assistant now remembers you across conversations. Core memory stores permanent facts (your name, projects, preferences), while daily notes capture session context and auto-expire after 30 days. Everything stays local on your machine. Docs →

Kimi K2.5 — in partnership with Moonshot AI — Kimi K2.5 is now the default model in BrowserOS. Open-source, multimodal, and great for browser automation. For a limited time, users get extended usage limits at no cost. Bring your own key from platform.moonshot.ai anytime.

SOUL.md — Shape your assistant's personality, tone, and boundaries. It evolves on its own as you interact — the more you use it, the more it feels like yours. Docs →

BrowserOS - v0.42.0

✨ What's new:

• SOUL.md — Your assistant now has a soul. Tell it how you like to communicate, set boundaries, shape its personality — and it adapts on its own over time. The more you use it, the more it feels like your assistant. Inspired by OpenClaw — thanks to @steipete for the great concept. Docs →

• Vertical tabs — One of the most requested features is here. BrowserOS now ships with vertical tabs by default. More screen space, better tab management, and a cleaner layout out of the box. Prefer horizontal? You can switch back anytime in settings. Docs →

• Long-term memory — Your assistant finally remembers you. Your name, your projects, what you talked about last week — it carries context across every conversation so you never have to repeat yourself. All stored locally on your machine. Also inspired by OpenClaw. Docs →
