# Save and Search AI Chats on Your Computer > Keep ChatGPT, Claude, Gemini, Perplexity and Grok chats on your own computer. Search them, ask them, carry them on. Kortex asks first and logs every send. https://www.kortex-notebooklm.com/library Chat Library # Save every AI chat. Find any answer in seconds. The Kortex Library keeps your chats from ChatGPT, Claude, Gemini, Perplexity and Grok on your computer, next to the YouTube videos and Gemini Notebook (formerly NotebookLM) notebooks you file with them. Search them, read them offline, and carry what they decided into another AI. [Add to Chrome](https://chromewebstore.google.com/detail/kortex/hdapplggdhndkblofffknpmnnnnbncbn) [What stays, what leaves](#privacy) [![The Library page: a sidebar of views, a list of saved chats by day with their site and tags, and a chat about three days in Lisbon open beside the list.](/images/library/all-chats.webp)](/images/library/all-chats.webp) All chats lists every saved chat by day. Open one to read it in full beside the list. ## Your chats stay private. - ### On this computer Saved chats live in a database inside Chrome on this computer. Search and **Ask my chats** run there too. - ### Asked before the first save Kortex asks once. Until you answer, nothing is saved. **Don’t save my chats** saves nothing, and you can change your answer at any time. - ### A log you can read The Library’s **Privacy** view lists each time chat text left this computer. The text itself isn’t kept. [![A notice beside a chat: Keep your AI chats in your Library? It says chats are saved only on this computer, with two buttons, Keep my chats in my Library and Don’t save my chats.](/images/library/consent.webp)](/images/library/consent.webp) The notice Kortex shows before it saves a single chat. [![The Privacy view, Sent from this computer: rows naming an MCP app, Notion, a copied pack, ChatGPT, Claude and Gemini Notebook, each with the chats sent, a character count and a time.](/images/library/privacy-log.webp)](/images/library/privacy-log.webp) Sent from this computer: when, where to, which chats and how many characters. Find ## Find any chat. ### Search all your AI chats Press **Ctrl+Shift+K** (**Cmd+Shift+K** on a Mac) on any website to search your chats, notebooks and videos. Search uses the words you remember and what each chat was about. So “cooking” finds a chat about recipes. A misspelled word still finds its chat. A chat opens at the message that matched. [![A search box over a web page. Typing lisbon lists a notebook, chats from Gemini, Claude, Grok, ChatGPT and Perplexity, and videos.](/images/library/search.webp)](/images/library/search.webp) One search across every AI, from any page. ### Ask your chats a question Type a question of three words or more in the Library’s search. Under **From your chats**, the closest passages from past answers show first. Each one opens at its message. Nothing is generated. These are your chats’ own words. [![A question about proofing sourdough in the fridge typed in the Library’s search. Under From your chats, one passage from a past answer about the cold proof, above related notebooks, chats and videos.](/images/library/ask-my-chats.webp)](/images/library/ask-my-chats.webp) The passage that answers it, from whichever AI said it. ### See when you’ve asked before You start a new ChatGPT or Claude chat and type your first question. Kortex looks for a past chat about the same thing, from any AI, and shows it above the chat box. Open the earlier answer instead of starting over. [![A card above ChatGPT’s chat box reading You’ve asked about this before, with an earlier question about sourdough hydration, the chat’s title, and Claude, Nov 9.](/images/library/asked-before.webp)](/images/library/asked-before.webp) Your earlier question appears above the chat box as you type. ### See related chats Under a chat, **Related chats** lists other chats about the same thing, from any AI. Kortex finds them by meaning. Click one to read it. [![A Claude chat about sourdough hydration open in the reader. Under it, Related chats from any AI lists a Perplexity, a Gemini and a ChatGPT chat.](/images/library/related-chats.webp)](/images/library/related-chats.webp) Related chats from any AI sit under the one you’re reading. Reuse ## Continue in any AI. ### Move a chat to another AI **Continue in another AI…** builds a handoff pack. It holds what the chat decided, what is still open, the key facts, your pins and your note. You pick the AI and read and edit the pack. Then Kortex opens a new chat there with the pack in the chat box. A model does not write anything in the pack. [![The Continue in another AI dialog: a choice of AIs, related chats to add, and an editable pack with a button that reads Open Claude with the pack.](/images/library/continue-in.webp)](/images/library/continue-in.webp) You read and edit the pack before it goes anywhere. ### Paste a past answer with ;ref Type `;ref` in any AI’s chat box. It lists past chats from any AI, with the closest in meaning to your draft first. Pick one and Kortex puts in the passage that matters, with a link back to the chat. [![A ChatGPT chat box with a draft about a grant narrative ending in ;ref. A menu above it lists past chats from Claude, ChatGPT, Gemini and Perplexity, the closest marked Related.](/images/library/ref.webp)](/images/library/ref.webp) The closest past chats, from any AI, appear as you type. ### Brief any AI on a project with ;pack Type `;pack` in any chat box and pick a folder. You get one project brief. It holds what the folder’s chats decided, plus its pins, highlights and notes. You read and edit it before it goes in. [![A chat box with ;pack typed in it and a menu above listing four Library folders, Work, Arts grant 2027, Lisbon in May and Thesis, with a line saying Enter shows the pack to read and edit.](/images/library/pack.webp)](/images/library/pack.webp) Pick a folder and read its pack before it goes in. ### Tell any AI about you with ;me `;me` adds your Memory facts as a short about-me pack. You edit it in a sheet first. Private facts are left out. Each AI starts from what you chose to share. [![An About me sheet over ChatGPT: 10 facts citing 5 chats, an editable text pack, and an Add to my message button.](/images/library/me.webp)](/images/library/me.webp) An about-me pack you edit before it goes into the chat box. Keep ## Keep the best parts. ### Every chat saved for you After you say yes, chats from ChatGPT, Claude, Gemini and Grok save in the background every few minutes. This works while Chrome is open and you are signed in to the site. Perplexity saves while a Perplexity tab is open. A chat you delete on its site stays in your Library. [![The Saving your chats sheet in the side panel: a main switch, then ChatGPT, Claude, Gemini, Perplexity and Grok, each with its saved count, a switch and a delete link.](/images/library/saving-sites.webp)](/images/library/saving-sites.webp) Each site says what saving is doing, with its own switch. ### Highlight and pin any line Select words in an answer on an AI site. Then **Pin** them or **Highlight** them in yellow, green, blue or pink. Highlights are still there when you reload the page. The **Highlights** view gathers them by site and color. [![Selected words in an AI’s answer with a small bar above them: Pin, Highlight and Remember.](/images/library/selection.webp)](/images/library/selection.webp) Select text in any answer to pin, highlight or remember it. ### Notes beside every chat A small tab on the edge of ChatGPT, Claude, Gemini, Perplexity and Grok opens a panel about the chat you are in. It shows your note (saved as you type), the answers you pinned, the questions you asked in order, the chat’s folders and tags, and related chats. [![A ChatGPT chat about a grant budget with the Kortex tab open beside it: a folder and tags, a note, a pinned answer, the questions asked, and related chats from Claude, Gemini, ChatGPT and Perplexity.](/images/library/kortex-tab.webp)](/images/library/kortex-tab.webp) The Kortex tab keeps your note, pins and related chats next to the chat. ### Memory you control Memory holds facts about you that you approved, each with where it came from. Select a sentence on an AI site and choose **Remember**, or add a fact yourself. When a fact stops being true, **No longer true** keeps it with an end date instead of deleting it. [![The Memory view: a list of facts, each marked You said or From a chat, with the chat it came from and the date.](/images/library/memory.webp)](/images/library/memory.webp) Each fact says whose words they were and which chat they came from. ### Search your YouTube videos too Videos you save from YouTube go to **Videos**. You can search them by what they are about. A video in a folder gets its transcript saved. A search can then open the video at the moment you want. [![The Videos view: YouTube videos as cards by day, each with its thumbnail, title, channel and length, and filters for channel, time and tag.](/images/library/videos.webp)](/images/library/videos.webp) Videos sit in the Library beside your chats. Organize ## Organized for you. ### Suggested folders When recent chats look like one topic, a card above **All chats** offers to make a folder or a notebook from them. Kortex works this out on your computer. **Not now** hides that kind of card for a week. [![A card above All chats: Sourdough, 3 recent chats from Claude, Gemini and Perplexity look like one topic, with a Make the folder button.](/images/library/suggested-folder.webp)](/images/library/suggested-folder.webp) Chats on one subject, from different AIs, offered as one folder. ### A timeline of your chats The **Timeline** groups your chats by week and names the topics you worked on, by meaning. Pick a topic to see only that topic’s chats for the week. [![The Timeline view. Each week lists its chats, with topic chips such as Upgrade, Grant, Sourdough and Lisbon. Upgrade is selected and shows only its chats.](/images/library/timeline-topics.webp)](/images/library/timeline-topics.webp) Each week’s topics, with the chats under them. ### See questions you asked two AIs **Asked twice** lists questions you asked more than once, often on two AIs. Choose **Keep together in a folder** or **They’re different**. Nothing is deleted. [![The Asked twice view: You asked Perplexity and ChatGPT the same thing, with both chats listed and the buttons Keep together in a folder and They’re different.](/images/library/asked-twice.webp)](/images/library/asked-twice.webp) The same question, put to two AIs, shown together. ### Folders for chats, videos and notebooks A folder holds chats, notebooks and videos on one topic. You can nest folders, give them one of six colors, pin one to the top, or make one private so its chats stay on this computer. [![The Folders view: eight folder cards in different colours, with chat and video counts. One is pinned to the top and one shows a lock for private.](/images/library/folders.webp)](/images/library/folders.webp) Folders in six colours, with the number of chats inside. ### Send a folder to Gemini Notebook **Sync to a notebook** sends a folder’s chats and videos to a Gemini Notebook as sources. It keeps the notebook up to date as chats are added or change. Nothing is removed from the notebook. [![A folder called Arts grant 2027 linked to a notebook, Arts grant research. Beside the folder’s tools it says 6 chats are in the notebook and that new and changed chats go there too.](/images/library/linked-folder.webp)](/images/library/linked-folder.webp) A linked folder shows how many chats are in its notebook. ### A weekly recap On your first visit after a Monday, a card above **All chats** sums up last week. It shows how many chats on which AIs, the topics, a question you asked twice, and one thing worth doing next. **Stop the weekly recap** turns it off. [![A card reading Your week, Nov 2 to 8: 21 chats with 5 AIs, chats per AI, topics, a question asked on two AIs and 7 highlights kept, with a Put them in a folder button.](/images/library/recap.webp)](/images/library/recap.webp) Last week in one card. ### Your year in AI **Your year in AI** counts chats per AI and per month, the topics you came back to and your longest chat. Kortex works it out on this computer and it stays there. [![A page titled Your 2026 in AI: 67 chats with 5 AIs, a bar chart by month, chats per AI, and the longest chat.](/images/library/year.webp)](/images/library/year.webp) A year of chats, per AI and per month. Take it with you ## Use your chats in other apps. ### Save chats to Notion **Save to Notion** copies a chat to a Notion page you choose. It includes the messages and your note, pins and highlights. If you save the same chat again, Kortex updates its page instead of making a new one. [![A chat’s menu open in the reader, with Save to Notion highlighted among Copy chat, Download as Markdown, Download as PDF, Open in Google Docs and Archive.](/images/library/notion.webp)](/images/library/notion.webp) Save to Notion sits in every chat’s menu. ### Markdown copies for Obsidian **Keep a Markdown copy…** writes one Markdown file for each chat in a folder you choose. It updates the file when the chat changes. Anything you write below the marker line is kept. Chats in a private folder are left out. [![The Keep a Markdown copy dialog: the chosen folder, switches to keep the copy up to date and include videos with a transcript, an Obsidian vault field, and Write all now and Done buttons.](/images/library/markdown.webp)](/images/library/markdown.webp) A folder of Markdown files, kept up to date. ### Connect Claude or ChatGPT with MCP Connect Claude or another assistant over [Kortex MCP](/docs/library-mcp). Use a key that gives access to only your chats, plus any extras you choose. The sheet shows how many tokens each option costs your assistant. [![The MCP Connection sheet in the side panel: a key label, a tool profile, and the options Everything and Just my chats, with token counts beside each.](/images/library/mcp-key.webp)](/images/library/mcp-key.webp) Choose what the key lets your assistant see. Also here: older chats from ChatGPT, Claude and Gemini export files, and a tour of everything above on your first visit. [Read the Library docs](/docs/chat-library). ## How it works 1. ### Add Kortex and answer the notice Add Kortex to Chrome and sign in. The first time you see the Library, it asks whether to keep your AI chats. **Keep my chats in my Library** starts saving. 2. ### Keep chatting as you do now New chats arrive on their own. Add older ones from the export file each site gives you. Kortex reads it on this computer. 3. ### Find it, ask it, carry it on Search from any page, ask your chats a question, or open another AI with a pack of what you decided. ## What stays on your computer. ### Stays on this computer - Chats, videos, highlights, pins, notes and Memory facts, in a database inside Chrome. - Search, suggestions, **Ask my chats** and **Write an answer**. These run here. Kortex downloads the model behind search once, from Hugging Face, and keeps it in Chrome. - The Markdown copy and your downloads, as files on this computer. - Your Notion sign-in token. Kortex’s server only swaps Notion’s sign-in code for the token. It keeps neither. - Zotero, which Kortex reads from the Zotero app on your computer. ### Leaves only when you act - A handoff pack, `;ref`, `;ask`, `;me` or `;pack` that you put into an AI’s chat box. - **Send to a notebook…**, a folder kept in sync with a notebook, a highlight you send, or the Kortex button on an AI site, to Gemini Notebook. - **Open in Google Docs** and **Save to Notion**. - Your own assistant reading the Library over [Kortex MCP](/docs/library-mcp). The call passes through a short-lived job on Kortex’s servers. The job deletes itself about an hour later. - ### Private folders stay here Make a folder private. Its chats and videos are then not offered to `;ref` or related chats, and are not sent to another AI, a notebook, Google Docs or an MCP tool. Search in your Library still finds them. - ### Secrets are hidden first Before text leaves, Kortex turns anything that looks like an API key, token, private key, password or card number into a label such as `[hidden API key]`. It only hides keys with a known shape or a labeled field, so read before you send. - ### Every send is listed **Sent from this computer** keeps the last 90 days, up to 2,000 entries. Downloads and copied packs are listed too, though they stay here. **Clear this list** empties it. **Outside the Library.** Kortex’s data collection is a separate setting, described in the [privacy policy](/privacy-policy). It covers page interactions and what is visible on the tab you are using, which can include a chat on screen. Turn it off under **Options** in the side panel’s ⋯ menu. **Your account and usage counts.** Your Kortex account is kept on Kortex’s servers. Kortex counts how features are used, as numbers per day. Library events never include chat titles, text or searches. ## Questions people ask Something we missed? [Ask us](#contact). ### Where are my chats stored? In a database inside Chrome on your computer. Chats, videos, highlights, pins, notes and Memory facts stay there, and search, Ask my chats and Write an answer run there too. The model behind search is downloaded once, from Hugging Face, and kept in Chrome. ### Does Kortex send my chats to its servers? Saving does not. Chat text from your Library leaves this computer only when you send it, and the Privacy view lists each time. One route passes through Kortex’s servers. A call from your own assistant over Kortex MCP travels as a short-lived job that deletes itself about an hour later. Kortex’s data collection is a separate setting, described in the [privacy policy](/privacy-policy). It can include what is on screen in the tab you are using. Turn it off under Options in the side panel’s ⋯ menu. ### Is anything saved before I agree? No. Kortex asks once: Keep your AI chats in your Library? The notice shows where you first see the Library. Until you answer, nothing is saved. YouTube history is separate and stays off until you turn it on in the Videos view. ### How do I stop saving, or delete what is saved? Open the side panel’s Chats tab and its Saving your chats sheet. Save my AI chats on this computer turns saving off. Each site has its own switch. Delete saved ChatGPT chats (and the same for each site) removes that site’s chats from the Library. It does not touch the chats on the site. Delete from Library in a chat’s ⋯ menu removes one chat and everything made from it. Its text is wiped from the database file, not just hidden. ### Which chats can it save, and how far back? Chats from ChatGPT, Claude, Gemini, Perplexity and Grok. Kortex reads each site’s newest 500 chats, and Gemini lists only about its newest 500 to 600. Older chats can come in from the [export file](/docs/library-import-exports) that ChatGPT, Claude or Google Takeout gives you. Kortex reads it on your computer. ### Does an AI write or change anything in my chats? No. Ask my chats shows your chats’ own words. A handoff pack is made of the chat’s own sentences. Write an answer shows up where Chrome has its own built-in AI model. It turns passages into a short answer that cites each one, on your computer. It never downloads that model until you click. ### Will my chats show up on my other computer? No. The Library lives in Chrome on one computer. To take chats elsewhere, download them or send them to a notebook. ### Can I connect my own AI assistant? Yes, over [Kortex MCP](/docs/library-mcp). A key with the Just my chats option gives your assistant your chat Library and nothing else. Chats in private folders stay out. Likely secrets are masked. Each call that carries chat text is listed in the Privacy view. ### Is Kortex made by Google, OpenAI or Anthropic? No. Kortex is an independent Chrome extension, not affiliated with or endorsed by Google, OpenAI, Anthropic, Perplexity or xAI. ## Start saving your AI chats. Install Kortex, say yes to the notice, and your chats start arriving in your Library.
