The extension watches for a keyboard shortcut plus a text selection, then surfaces a GPT assistant picker right where you are reading.
Instead of hard-coding one model, you choose which GPT assistant handles the request each time, so you can route easy questions to a fast assistant and hard ones to a stronger one.
The assistant's answer is generated from the text you highlighted, so you can ask about a paragraph, a table cell, or an error message without retyping it.
Everything happens inline on the page you are already on, so there is no copy-paste loop and no context switching into a separate chatbot tab.
The developer's declaration states that the extension does not collect or use your data and does not sell it to third parties.
Most chat-based AI tools ask you to leave what you are doing. Select AI Extension takes the opposite approach: it comes to the text. A shortcut key plus a drag of the mouse brings up your GPT assistants, and the one you choose answers against the passage you just selected. For people who constantly bounce between reading and asking, that removes a surprising amount of friction.
The interesting design choice is the assistant picker. Rather than committing you to a single model, the extension lets you decide per selection which assistant should handle it, so the same gesture adapts to either a quick factual lookup or a heavier reasoning task. The result is a small, composable layer on top of the GPT assistants you already have access to.
Select AI Extension is an independent developer tool published on the Chrome Web Store under the developer name vthinkxie. It has a small but positive user base and has not been updated since March 2023, so it is best treated as a simple utility rather than an actively evolving product. If your workflow is "highlight something, ask an assistant about it, stay on the page," it does exactly that and nothing more.
Select a confusing paragraph while researching and hand it to an assistant tuned for explanation, without losing your place in the original source.
Highlight a tricky code snippet or error message on a docs page and route it to an assistant that can explain what it means, right where you found it.
Pull out a clause, figure, or claim from a long page and ask a specific assistant to interpret it, keeping the selection as the only context you need to provide.
Choose the assistant that fits each task, using a lighter one for simple lookups and a stronger one for analysis, all from the same selection menu.
