Aside vs Opera Neon

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.

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.
