MoltBrowser vs Opera Neon

MoltBrowser is a free, open-source AI browser with an embedded on-device model and privacy features. Its page-aware AI can summarize articles, explain code, extract table data, and translate pages. It runs open models such as Llama, Mistral, Phi, and Qwen locally; the project also documents using personal keys with OpenAI, Anthropic, Gemini, and compatible endpoints. Its agent can click, scroll, navigate, and fill forms, and tasks can be scheduled to run automatically. Browsing memory and AI conversations are stored on the device; conversation history can be searched, exchanged as JSON, or wiped in one action. MoltNet routes traffic over Tor and allows exit-country selection, while MoltShield blocks ads and trackers, including YouTube ads, and dismisses cookie banners. The maker says the browser alters device fingerprint signals and masks the user's IP address. Builds are listed for Apple Silicon macOS, Windows 10/11 x64, and Linux x64. Chrome extension compatibility is advertised. iOS and Android are listed as in development, not as available builds.

Opera Neon is a Chromium-based AI browser for macOS and Windows. It can open pages, research, fill forms, and create content for a user. Neon Chat uses open pages as context and supports image generation, video generation, photo-to-video generation, and web-app creation. Neon Do works with the current page, manages tabs, runs scheduled tasks, and connects with Google tools. Research agents include Deep Research, One-Minute Research, and Local Research. Neon Cards save instructions for reuse across Chat, Do, and Research Agents. MCP connections are supported, with Claude Code, Lovable, and n8n named as working tools. Connections are read-only by default; actions require permission, and Neon Do can be paused, stopped, or taken over. Opera says chats and workflows remain on its servers for 365 days, can be deleted, and are not used for training. An Opera account is required. The free plan includes basic AI chat, ad blocking, a free VPN, Browser CLI, and MCP Connector. Standard costs $19.90 a month.
