Arc Search vs MoltBrowser

Arc Search is a free browser centered on Browse for Me, which searches multiple pages and produces an answer on a custom webpage. Its built-in blocker is described as stopping ads, trackers, pop-ups, and cookie banners. Other features include reader mode, incognito mode, website translation, and voice search. Inactive tabs are archived automatically, with help documentation listing intervals from 12 hours to 30 days. Browse for Me is the default search option; alternatives include Google, Bing, DuckDuckGo, Ecosia, Perplexity, and Kagi. Arc Sync can share desktop Spaces, pinned tabs, and Today tabs with Arc Search on iOS, but is unavailable on Android, and tabs created in Arc Search do not sync back to desktop. The maker says Browse for Me sends command-bar and search-result content to OpenAI to generate summaries. Arc Search supports iOS 16 or later and Android 10 or later. The maker also says Sync sidebar data uses end-to-end encryption, but the product is not currently SOC 2 or ISO 27001 certified and does not offer account MFA.

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.
