Students use Google Gemini for homework help, exam prep, essay feedback and class notes, on a free account or a Google AI Pro student plan. By midterms the sidebar holds a hundred chats titled by their first line and the explanation that finally made sense is somewhere in the middle. The Gemini module of AI Toolbox (formerly ChatGPT Toolbox), a Chromium extension by Infi Developments, adds a folder per course, full-text search across every message, automatic subject tags, bookmarks on the answers worth revising, and export to TXT, Markdown or PDF for notes.
Free with 2 root folders, 5 search results per query, Smart Tags on your 50 most recent chats, bookmarks in 2 conversations and TXT export. Premium removes the caps and adds the Advanced filters, Markdown and PDF export and bulk actions.

The gap
Gemini has a title-only sidebar search, Gems for custom tutors, and a share menu that sends one reply to Docs. None of them find the worked example from week three by searching for the theorem's name.
A study session is worth keeping when Gemini explains something in a way the textbook did not. In Gemini that explanation sits inside a reply in a chat called "can you explain this", one of dozens per course. The sidebar search matches titles, Gems are assistants rather than folders, and Takeout exports the whole account as HTML rather than a page of notes.
AI Toolbox keeps the Gemini interface and adds the missing layer in the browser: folders per course and topic, an index of every message you can search by keyword, automatic subject tags, bookmarks with colour labels on the answers to revise, and per-conversation export as a file you can paste into your notes. Nothing is uploaded; the index lives in your browser.
Why it matters
Here is what you cannot do with Gemini alone:
The longer a course runs, the more of the good explanations sit in old replies. Folders, search and bookmarks are what make them revisable.
Step by step
From install to exported notes. Steps one to four are on the free plan; the Advanced filters, Markdown and PDF export in step five are where Premium starts.
About three minutes
Smart Tags: every chat labelled by subject
Smart Tags reads each conversation locally and files it under Coding, Math and Science, Research, Writing or Business, with custom rules for your own course names. Open a tag to see every chat in it. Free covers your 50 most recent conversations; Premium tags the whole history.
The four features students use
Every capture below is the extension running inside gemini.google.com. The plan each feature needs is stated in the text.
Search
The index covers every message in your history, so a theorem name, a formula or an essay prompt finds the reply that contains it, highlighted, with a link into the chat. Cmd/Ctrl+Shift+F opens it anywhere on gemini.google.com. Free returns five results per query; Premium adds unlimited results with the Advanced filters.
Bookmarks
Bookmark any Gemini message with a note and one of six colour labels, one colour per exam or assignment. The panel lists them with their conversation titles and opens the chat scrolled to the message. Free: bookmarks in two conversations. Premium: unlimited.
Filters
Advanced Search adds exact match for a formula or a quote, Questions or Answers to keep one side of the conversation, and past week, month, year or a custom date range to narrow a semester down to a unit. These filters are Premium; a plain query on the free plan searches every message with no filter.
Export
Any conversation exports from Manage Chats as TXT, Markdown, JSON or PDF. Markdown carries YAML frontmatter (title, date, model, URL, source) and pastes into Notion or Obsidian; PDF prints as a study pack. Free exports as TXT; Premium unlocks the other formats and bulk export of a whole course folder before the semester ends.
Scenarios

FAQ
Yes, with no time limit and no student verification. The free plan includes 5 search results per query, 2 root folders with unlimited subfolders, Smart Tags on your 50 most recent chats, bookmarks in 2 conversations, 3 Context Mentions a day and single-chat TXT export. Premium ($9.99/month or $99 once) removes the caps and adds the Advanced filters, Markdown, JSON and PDF export and bulk actions.
Yes. AI Toolbox indexes every message in your Gemini history in the browser, so the theorem, formula or essay topic returns each reply that contains it, highlighted, with a link into the chat. Press Cmd/Ctrl+Shift+F on gemini.google.com. Free shows five results per query; Premium shows all of them and adds exact match, Answers only and a date range, which is how you narrow a semester to one week.
Open Manage Chats, tick the conversation and choose a format. TXT is free and pastes anywhere. Markdown (Premium) keeps headings, lists and code blocks and opens with YAML frontmatter, so it drops into Notion or Obsidian; PDF (Premium) prints as a study pack. Premium can also export a whole course folder at once.
It works on any Chromium browser where the Chrome Web Store is allowed, including Chromebooks. Some school-managed devices block extension installs by policy; if the Web Store's Add to Chrome button is greyed out, that is the administrator's setting rather than the extension. It works with a school Google Workspace account as well as a personal one.
Yes. The search index, folders, tags, bookmarks and saved prompts are stored in your browser, and every search runs locally. Conversation content is never sent to our servers; the only account detail that reaches them is the email used to verify a Premium plan. PDF export is the one exception: the conversation is rendered on our server and returned without a copy being kept.
No. It does not answer questions or write anything; Gemini does that. AI Toolbox organises, searches and exports the conversations you already have, so what you learned stays findable. Follow your school's rules on AI use.
Any Chromium browser installed from the Chrome Web Store: Chrome, Edge, Brave, Opera and Arc. There is no Firefox version.
