📝 TL;DR 📝 Aside is a new YC-backed AI browser that signs into your existing accounts and performs real tasks inside them, emails, dashboards, internal tools, rather than just reading public web pages. It runs locally with encryption, lets you bring your own Claude or ChatGPT subscription instead of paying for a separate AI bill, and claims top scores on agentic browsing benchmarks. The capability is genuinely impressive. It also raises real questions about agent permissions that are worth understanding before using it on anything sensitive. 🧠 Overview 🧠 Most AI browser agents today work by reading what is publicly visible on a page or relying on pre-built integrations with specific services. Aside is positioning itself differently: it logs into your actual accounts the same way you would, using saved credentials, and operates inside them directly. That means it does not need a custom integration for every tool you use. If you can log into a website and do something there, Aside is designed to be able to do it too. This is a meaningfully different category of capability than reading and summarizing web content, and it comes with a correspondingly different risk profile. The privacy framing, local processing, encrypted storage, credentials never exposed to the AI model itself, is clearly built to address the obvious concern that comes with granting an AI agent that level of account access. 📜 The Announcement 📜 Aside is a desktop browser, currently available for macOS, built by a Y Combinator-backed startup. The pitch is that it works across logged-in websites and accounts directly rather than depending on integrations, handling tasks like managing communications, replying to messages, working with documents and spreadsheets on your computer, and operating inside dashboards and internal tools. On benchmarks, Aside reports ranking first across three agentic browsing evaluations: Online-Mind2Web, BU-Bench-V1, and Odyssey. The company's own published numbers show Aside scoring 99.0% on these combined evaluations, ahead of Browser Use at 97.7%, GPT-5.4 at 92.8%, Claude Opus 4.8 at 84.0%, and ChatGPT Atlas at 70.0%. These figures come directly from Aside's own marketing materials and have not yet been independently verified by a third party, which is worth keeping in mind before treating them as settled fact.
