The browser built to do real work for you
Last verified:
Aside is an AI browser that completes real work across the websites you already use. It can sign in through your browser, work inside email, dashboards, internal tools, docs, and spreadsheets, and keep going when a task takes minutes or hours. Unlike agents that depend on integrations, Aside uses the web the way you do. Browsing history becomes local memory, so it knows which tools and context matter. Its password manager lets agents autofill credentials without exposing secrets to the AI. Sensitive actions like payments, posts, and messages wait for your approval. Aside is built as a fast daily browser plus a state-of-the-art browser agent. It ranks #1 on Online-Mind2Web, BU-Bench-V1, and Odysseys, and runs local-first with device-protected memory and data.
