AI BYTS: Keep the source within reach
Two small experiments keep the editable object and the original source close enough to inspect.

Source notes: Google documents editable file creation and revision in Gemini (opens in a new tab) and source-grounded textbook access in Gemini Notebook (opens in a new tab). Both experiences are documented here, not product-tested in this production run.
Let AI start the file, then take over
Ask Gemini for a one-page guide about a fictional neighborhood club. Keep it harmless: three meeting rules, one short welcome paragraph, and a simple checklist.
When the generated file opens in Gemini's preview, do not immediately ask the model for another version. Take over the file yourself. Correct one sentence directly. Then highlight a different paragraph and ask Gemini to make only that selection clearer for a first-time visitor.
Before exporting anything, compare the result with the version you first received. Did your manual correction remain? Did the highlighted revision stay inside its boundary? Does the file still use the structure you asked for?
Google documents in-chat generation, preview and editing for several file types, but this component was not tried in the product. Availability, formatting fidelity and export behavior can vary. The useful experiment is the handoff: let AI begin the file, make one human correction, then give one bounded part back.
Use the explanation as a route back to the textbook
Open a named textbook in Gemini Notebook and choose one idea that is genuinely confusing. Ask for a plain-language explanation in a short paragraph, followed by the passage in the textbook that the explanation depends on.
Read the passage yourself. Does it support the explanation? Does the surrounding page add a definition, exception or diagram that changes the answer? If the citation points somewhere else, ask the question again with the chapter and section named.
Finish by writing one sentence in your own words and checking it against the source. The goal is not to make the textbook disappear. It is to use the explanation as a route back into a specific, inspectable source.

Google says Gemini Notebook now includes hundreds of no-charge textbooks from named providers. This component was not tried in the product, and catalog access can vary by account, region and subject. Treat the answer as help reading the book, not as a replacement for it.
