claude.ai can star a conversation, but nothing native marks the one message inside it that mattered. The Claude module of AI Toolbox (formerly ChatGPT Toolbox), a Chromium extension by Infi Developments, adds a Bookmark toggle to every message's action bar and a Bookmarks panel next to Share: save a reply or one of your own prompts in one click, then jump straight back to it, scrolled into view, even in a conversation hundreds of turns long.
Free with bookmarks in 2 conversations. Premium removes the conversation cap; room for 200 bookmarked messages per chat either way.

The Bookmarks panel on claude.ai
The gap
A Claude conversation that solves something real runs long. Somewhere in it is the reply you will need again: the fix, the plan, the paragraph. Claude keeps the conversation; it has no way to keep the moment.
The native options all operate at the wrong level. Starring marks a whole chat. Copying an answer into a notes app saves the words but detaches them from the conversation and the link back. And rereading is worse than it sounds, because Claude renders long chats in pieces as you scroll, so even Ctrl+F only sees the part currently on screen.
AI Toolbox works at message level. The bookmark lives on the message itself, inside the conversation, and the panel takes you back to it in one click. Everything is stored in your browser; nothing about your conversations is uploaded.
Why it matters
Here is what you cannot do with Claude alone:
A bookmark is the cheapest note you can take: one click at the moment you already know something matters.
Step by step
Five steps from install to jumping back. Everything here is on the free plan.
About a minute
The toggle, where Claude's own buttons live
The Bookmark toggle sits in the action bar of every message, next to copy, thumbs up and retry, styled like Claude's own controls. It appears on your prompts as well as Claude's replies, and clicking it on an already-bookmarked message removes the bookmark.
What bookmarks can do
Every item below is in the shipping Claude module. The core workflow is free; the only paid difference is how many conversations can hold bookmarks.
The toggle sits in every message's action bar: Claude's replies, your own prompts, the message with the file attached. One click saves it, one click removes it.
Plan: Free
Claude renders long conversations in pieces. AI Toolbox resolves each bookmark from its local copy of the chat and scrolls you to the exact message anyway.
Plan: Free
The Bookmarks panel shows each saved message as it looked, code blocks and math included, so you can tell your bookmarks apart before you jump.
Plan: Free
Bookmarks sits next to Claude's own Share button in every conversation, listing what you saved in the chat you are looking at.
Plan: Free
Claude bookmarks live in your browser's extension storage, keyed to the Claude account you are signed in to. They are not uploaded anywhere.
Plan: Free
Up to 200 bookmarked messages in a single conversation and 1,000 across your history, on any plan.
Plan: Free
The free plan holds bookmarks in 2 conversations at a time. Premium removes that gate so every project thread can carry its own saved moments.
Plan: Free: 2 conversations. Premium: unlimited
On ChatGPT, Gemini and Grok, bookmarks add a note, one of six colour labels and a global viewer across every conversation. Claude bookmarks are plain for now.
Plan: Per module
Bookmarks ship on every module. Compare Claude plans.
In detail
One click
AI Toolbox adds the toggle beside Claude's own copy and feedback buttons, styled to match, so saving a message costs one click mid-conversation. Click it again on a bookmarked message to remove it. If the free plan's two-conversation allowance is used up, the toggle offers the upgrade instead of failing silently.
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 conversation, with the matching sentence highlighted. The two together are how a long Claude history stays usable.
Other modules
The same bookmark workflow ships on the other three modules with more attached: a freeform note, one of six colour labels, a viewer that lists saved messages across every conversation, and sync to your AI Toolbox account. Claude bookmarks are plain single-click saves for now; the capture shows the Gemini panel.

FAQ
No. claude.ai lets you star a whole conversation in the sidebar, but there is no native way to mark a single message inside one. AI Toolbox adds a Bookmark toggle to every message's action bar and a Bookmarks panel in the conversation header, next to Share.
The free plan holds bookmarks in 2 conversations at a time; Premium ($9.99 per month) or Lifetime ($99 one-time) removes that gate. Within a conversation there is room for 200 bookmarked messages, and 1,000 across your history, on any plan.
The conversation scrolls to that exact message. Claude renders long chats in pieces as you scroll, so AI Toolbox resolves the bookmark from its local copy of the conversation and navigates there even when the message is not currently on the page.
Both. The toggle appears in the action bar of every message, so you can save the instruction that produced a great answer, the message where you attached the spec, or the reply itself.
On Claude, the Bookmarks panel shows the saved messages of the conversation you have open. A global viewer across every conversation, plus notes and six colour labels per bookmark, ships on the ChatGPT, Gemini and Grok modules; Claude bookmarks are plain single-click saves for now.
No. Claude bookmarks are stored in your browser's extension storage on the device where you made them, keyed to the Claude account you are signed in to. They never leave your machine. If you need a portable copy of a conversation, export it as Markdown or PDF instead.
The same extension includes full-text Search History: 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.
AI Toolbox works on Chrome, Edge, Brave, Opera, Arc and any other Chromium-based browser from a single Chrome Web Store install. Firefox is not supported.
