SurfMind
A browser extension that adds an AI chat sidebar to every website you visit, aware of the page you're actually looking at.

Description
Copy-pasting page content into a separate ChatGPT tab to ask a question about what you're reading is a small but constant annoyance. SurfMind removes that step by living inside your browser as a sidebar: it already knows the page you're on, so you can ask about it directly, summarize it, or pull in other open tabs for multi-page research.
SurfMind connects to 100+ AI models — GPT, Claude, Gemini, DeepSeek, Meta LLMs, or custom OpenAI-compatible and local endpoints — and adds image generation/editing, document and PDF upload for file-based queries, and a browser automation agent that can act on pages for you. It runs on Chrome, Firefox, Safari, Edge, Opera, Brave and Arc, plus an iOS Safari extension. The free tier is fully functional indefinitely with basic chat access to all 100+ models; Pro is a one-time $39 purchase (not a subscription) unlocking browser automation, side-by-side model comparison, web search and file uploads — AI usage itself is billed separately via the provider, SurfMind's own credits, or free local models.
💬 Our review
The short version: SurfMind is a strong pick if you want one AI sidebar that works everywhere instead of separate extensions per model — the one-time-purchase Pro tier is unusually generous in a market full of subscriptions.
Established competitors like Merlin and Sider run on monthly subscriptions and have longer track records, deeper per-site integrations, and larger user bases, which makes them the safer choice if reliability matters more than price. SurfMind's bet is that a single $39 one-time payment for lifetime Pro access beats paying $10-20/month indefinitely elsewhere — over a year or two that math clearly favors SurfMind, as long as the extension keeps getting maintained. Given the fully-functional free tier, there's little risk in trying it before deciding whether the Pro automation features are worth the one-time fee.
