In their own words
Aside
Aside is an AI browser designed to carry out complex tasks across websites where the user is signed in. It can handle sign-ins, messages, payments, internal tools, and files on the computer. Aside works directly with websites and accounts, so separate integrations do not need to be configured. Users can use a ChatGPT or Claude subscription, or bring their own API key. The browser turns browsing history and task context into editable Markdown memory stored on the device. Its Aside Vault password manager fills website credentials without exposing them to the agent and records credential use; it can import from 1Password, Apple Passwords, Bitwarden, Dashlane, LastPass, and Chrome. The maker describes local data protection, Secure Enclave, post-quantum encryption, and filesystem and network isolation. It says sensitive actions such as payments, posts, and messages wait for user confirmation. Aside runs on macOS and Windows. The Free plan includes 500 credits per month and up to three routines. Pro costs $20 a month; Max costs $200 a month.
BrowserOS
BrowserOS is an open-source Chromium-based browser with AI agents for carrying out web tasks from natural-language directions. The agents can navigate, click, type, fill forms, extract data, and run workflows across multiple steps. Chat Mode answers questions about the page in view; visual Graph Mode for repeatable workflows is marked as coming soon. BrowserOS supports Gemini, Claude, OpenAI, and local models through Ollama or LM Studio. Its maker lists more than 40 MCP app integrations, including Gmail, Slack, Notion, and Calendar, as well as 53 built-in browser tools. An included MCP server connects with Claude Code, Gemini CLI, or Codex. As a Chromium fork, it supports Chrome extensions and import of Chrome bookmarks, passwords, and settings. Browsing data stays on-device unless cloud syncing is enabled; syncing is off by default, and synced activity is encrypted on BrowserOS servers. BrowserOS says it does not store or log AI prompts or responses, though providers may handle submitted data under their own policies. It is free and licensed under AGPL-3.0.
