Features & Capabilities

Brain OS is an open-source AI memory system that runs entirely on your machine. This browser agent gives it eyes — automatically capturing and classifying every page you visit so your AI brain remembers what matters.

No configuration needed. Install the extension, start browsing. Your brain is auto-discovered at http://127.0.0.1:45678.

What it captures: Full page content (articles, docs, code), Open Graph / JSON-LD structured data, code blocks, engagement signals (scroll depth, time on page, clicked links). Pages are classified into types (article, code, docs, video, product, social, etc.) and importance-scored 1-10.

Privacy-first: Passwords, API keys, tokens, emails, and credit card numbers are stripped from captured content before saving. All data stays on your machine — never sent to external servers.

Smart features: 5-minute URL deduplication, SPA support via MutationObserver, offline queue with retry, zero-config auto-discovery, manual capture, and a live stats popup.

Is Brain OS — AI Agent Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Brain OS — AI Agent requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Brain OS — AI Agent is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
