Selection context
Attach selected documentation passages to a question.
Readers can select text in the documentation and click Ask AI (or press ⌥A). Glossen then:
- opens the chat panel;
- attaches the passage to the current conversation's draft;
- focuses the question input.
Nothing is sent until the reader submits a question.
What a passage contains
Each passage keeps:
- the page title and URL where it was selected;
- the selected text;
- the nearest heading above the selection, with its anchor in the URL when the heading has one.
These stay attached even if the reader navigates to another page before sending.
Multiple passages
New selections are added to the existing ones, even from different pages. Each passage shows as a removable preview above the input. Glossen sets no limit on the number or length of passages; the model's context window and request size still apply, and Glossen shows an error when they're exceeded.
After sending, the passages clear from the input and stay visible on the sent message. They remain part of the conversation for follow-up questions.
Where selection works
The Ask AI button only appears for text inside the documentation content (#nd-page by default, see contentSelector). It doesn't appear for text in chat answers, navigation, the table of contents, buttons or inputs. Add data-glossen-ignore to any element to exclude it.
On touch devices the button appears below the selection so it doesn't cover the system selection menu.
Turn selection off with selection={false}.
