NAME + PRODUCT
What is Aside Browser?
Aside is a standalone Chromium desktop browser, not a Chrome extension. Its pitch is a browser rebuilt for people and agents: ask for real work in messages, dashboards, docs, or spreadsheets, then let the agent operate the websites.
Agent-first browsing
Marketing focuses on completing tasks across logged-in email, dashboards, internal tools, docs, and spreadsheets without wiring a long integration list.
Local memory narrative
Browsing history is turned into on-device memory so you do not re-explain context every task—Aside says that memory stays local.
Agent password manager
Credentials are autofilled for sites without exposing secrets to the model; sensitive actions (payments, posts, messages) wait for human approval.
CURRENT FACTS
Features, support, and pricing
The product details below were checked on Aside’s official pages and changelog on September 7, 2026. Plans, limits, and platform support can change.
SOTA browser-agent pitch
Aside says it ranks #1 on Online-Mind2Web, BU-Bench-V1, and Odysseys versus Browser Use, GPT, Claude, and Atlas. Independent reviews note these figures are self-reported.
Effort / Ultrabrowse modes
Reviewers describe a reasoning-level control, with a long-horizon mode meant to keep pulling context until a job finishes.
Human-in-the-loop gates
Sensitive actions are meant to pause for confirmation so the agent cannot spend money or post without you.
Windows and macOS signals
Aside’s official changelog now documents Windows-specific fixes as well as macOS features. The marketing page does not publish a clear platform matrix, so confirm your OS in the download flow.
READ BEFORE YOU SWITCH
Early-product caveats to keep honest
Third-party review coverage (for example eesel’s 2026 write-up) treats Aside as promising but early—not a finished enterprise default.
Very fresh product
Launch buzz and demos outpace long-term production proof. Early users already report bugs typical of week-one software.
Benchmark skepticism
Leaderboard claims live in vendor-controlled repos. Treat them as marketing until replicated by neutral labs.
Credit-based plans
Aside now lists Free ($0), Pro ($20/month), and Max ($200/month). The free plan includes 500 monthly credits; heavier research and routines require paid capacity.
Pivot history
YC materials still surface an earlier sales-call assistant story. Confirm you are evaluating the current browser agent product, not the old narrative.
