Arc Search vs BrowserOS neo

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.

BrowserOS neo is a free, open-source browser that lets AI agents operate through browser sessions you are already signed into. Agents can open tabs, navigate, click, and read pages while you remain signed in. The browser connects through MCP to Claude Code, Claude Cowork, Cursor, Codex, VS Code, Zed, and GitHub Copilot. Multiple agents can work in separate tabs while you browse. Each run is saved as a scrubbable video for replay. The maker says sessions, screenshots, replays, settings, and logins stay on your machine rather than being sent to its server. Chrome logins can be imported in one click. BrowserOS neo sends compact page snapshots instead of raw HTML and can batch actions in one call. It runs on Linux, macOS, and Windows, uses Chromium, and is licensed under AGPL-3.0. It is free, has no free trial, and requires your own AI provider keys.
