Trash.

SEER is a browser extension for people who constantly interrupt what they are doing to look something up. Rather than opening a new tab, reformulating a question in a search engine and sifting through results, you keep working in the current page and let the extension answer in context. The publisher's own description frames it as a way to navigate any platform and get the information you need right away.
The extension is free, very small (around 394 KiB) and published by an individual developer. The Chrome Web Store listing carries version 0.0.1, updated in August 2024, and a small user base — in other words, it is an early build. The listing title itself references a Next.js Chrome extension starter template, which suggests the product is a working demonstration of an AI assistant concept rather than a mature, feature-complete platform.
On privacy, the developer discloses that SEER handles user activity data and declares it is not sold to third parties, not used for unrelated purposes and not used for creditworthiness or lending decisions. Because the tool is at an early version and updated infrequently, treat it as a convenient experimental helper rather than something to depend on for critical workflows.
Get a short answer about something you encounter in an article or document without abandoning your reading position.
Ask for help navigating a platform you use rarely, instead of digging through menus and help pages.
Keep a research session in one tab by resolving small questions in place rather than opening a dozen search tabs.
Add a small free assistant to Chrome for occasional lookups when you do not need a full subscription product.
