Grok inside X can bookmark a whole conversation; nothing native marks the one reply inside it that mattered. The Grok module of AI Toolbox (formerly ChatGPT Toolbox), a Chromium extension by Infi Developments, adds a bookmark and color control to every Grok reply on grok.com and x.com/i/grok, and a Bookmarks button in Grok's top bar that lists every saved reply across all your conversations. Click Open and the chat scrolls to that exact reply and flashes it.
Free with 2 bookmarked replies. Premium removes the cap: unlimited bookmarked replies.

The Bookmarks viewer on Grok
The gap
A Grok conversation that solves something real runs long, whether it started on grok.com or inside X. Somewhere in it is the reply you will need again: the fix, the analysis, the paragraph. Grok keeps the conversation; it has no way to keep the moment.
The native options all operate at the wrong level. Bookmarking on X marks a whole conversation and lives in your X bookmarks, not in Grok. Copying an answer into a notes app saves the words but detaches them from the conversation and the link back. And rereading means scrolling a long thread top to bottom on whichever surface it happened to be on.
AI Toolbox works at reply level. The bookmark lives on the reply itself, outlined in its color inside the conversation, and one viewer in Grok's top bar lists every saved reply from both surfaces. Because the list is keyed to your X account, it is the same list on grok.com, on x.com/i/grok and on any device you sign in on.
Why it matters
Here is what you cannot do with Grok alone:
A bookmark is the cheapest note you can take: one click at the moment you already know something matters.
Step by step
Six steps from install to jumping back, on grok.com or inside X. Everything here is on the free plan.
About a minute
The bookmark and color control in a reply's action row
The same two-button control ships on the Gemini module too: the bookmark toggle, and once a reply is saved, the tag icon for its color. On Grok it sits right after the Dislike button in each reply's action row, on grok.com and inside X alike. The capture shows the control on the Gemini module; the Grok control is identical apart from the host styling.
What bookmarks can do
Every item below is in the shipping Grok module, verified in its source. The whole workflow is free; the only paid difference is how many replies you can bookmark.
The toggle sits after Dislike in every reply's action row on grok.com and x.com/i/grok. One click saves the reply with a short preview; one click removes it.
Plan: Free
Tag a bookmarked reply red, orange, green, blue, purple or pink from the tag icon beside the toggle. The reply is outlined in that color in the conversation, and the viewer can filter by it.
Plan: Free
A Bookmarks button in Grok's top bar opens every saved reply from all your chats in one list, newest first, each with its preview and conversation title.
Plan: Free
Click Open and the conversation scrolls to the exact message with a highlight. Bookmarks from other conversations open that chat first, then finish the jump once it has loaded.
Plan: Free
Bookmarks are keyed to your X identity, so a reply saved at x.com/i/grok shows in the viewer on grok.com and the other way round.
Plan: Free
A bookmarked reply keeps a colored outline in the conversation itself, so you can spot it while scrolling even without opening the viewer.
Plan: Free
With Premium, bookmarked replies are unlimited, in a single conversation and across your history. Previews store up to 220 characters of the reply.
Plan: Premium
The free plan holds 2 bookmarked replies. Premium removes that cap so every project thread can carry its own saved moments.
Plan: Free: 2 bookmarked replies. Premium: unlimited

In detail
Refinding things
A bookmark takes you back to a moment you knew was important when it happened. For everything you did not think to save, the same extension ships full-text Search History across every synced Grok conversation on both surfaces, with the matching sentence highlighted. The two together are how a long Grok history stays usable.
Two levels
Bookmarks work at message level; folders work at conversation level. Keep the chats for one project together with nested folders, and inside them mark the individual replies worth returning to. Folders are added by search from the folder manager, nothing to drag, and the free plan includes two root folders with unlimited subfolders.
Beyond Grok
Message bookmarks with a global viewer also ship on the ChatGPT and Gemini modules, with notes on ChatGPT and the same six colors on Gemini; Claude bookmarks are plain single-click saves for now. Search all platforms runs one query across your ChatGPT, Claude, Gemini and Grok histories with results grouped by platform, from an opt-in on-device index. Free shows the 5 newest matches across all sites plus how many more each site has; Premium shows every result.

Use cases
Works best with search
Bookmarks keep the moments you saw coming. Pair them with full-text Grok search for everything you didn't.
Add to Chrome, freePrivacy
Grok bookmarks are saved to your AI Toolbox account so the same list shows on grok.com, on x.com/i/grok and on every device you sign in on. The record is small and the conversation itself stays in your browser.
Pricing
Free covers the whole bookmark workflow for 2 bookmarked replies, alongside full-text search and folders. Premium removes the caps on Grok and adds Markdown, JSON, PDF and bulk export (TXT export of a single chat is free). All Access does the same across ChatGPT, Claude, Gemini and Grok, paid once. Not an AI subscription: you keep using your own X account and whatever Grok plan you already have.

FAQ
Not at message level. Grok inside X can bookmark a whole conversation into your X bookmarks, and grok.com keeps a history list, but neither surface can save or color-code an individual reply inside a conversation. AI Toolbox adds a bookmark and color control to every Grok reply's action row and a Bookmarks viewer in Grok's top bar on both surfaces.
The free plan holds 2 bookmarked replies; Premium ($9.99 per month) or Lifetime ($99 one-time) removes that cap, so bookmarked replies are unlimited.
The conversation scrolls to that exact reply and flashes it. If the bookmark belongs to a different conversation than the one you have open, AI Toolbox opens that conversation first and finishes the jump once its messages have loaded. On x.com, where Grok gives messages no ids, the reply is matched by its content, so the jump still lands.
On Grok the control is added to Grok's replies only. The bookmark toggle appears in each reply's action row after the Dislike button, and there is no equivalent control on your own prompts. If you need the prompt as well, the reply preview and the conversation title get you back to the exchange, or use full-text search, which matches your prompts too.
Yes. The Grok module is a single install that runs on both surfaces, and bookmarks are keyed to your X identity, so the viewer on grok.com shows replies you saved inside X and the other way round. The bookmark control sits in the same place on both: after Dislike in a reply's action row.
Yes. Grok bookmarks are saved to your AI Toolbox account rather than to one browser, so they appear in the viewer on any device where you sign in to Grok with the same X account. What is stored is the message reference, a preview of up to 220 characters and the color; the conversation itself stays in your browser.
Not in the Grok module today: Grok bookmarks carry one of six colors and a text preview. The colors are the way to group them, and the viewer filters by color. Notes on bookmarks ship on the ChatGPT module only.
The same extension includes full-text Search History for Grok: type a word or phrase and every synced conversation that contains it comes back with the matching sentence highlighted, 5 results per query on the free plan. Bookmarks are for the moments you knew mattered; search covers everything else.
Grok signs you in with your X account rather than an email, so Premium unlocks on the X handle you enter at checkout. Use the exact handle you sign in to x.com and grok.com with, and unlimited bookmarks unlock for that handle on both surfaces.
