[Use cases](/use-cases) 2. Writers and creators # Save posts and videos as you browse. Kortex adds a send button to posts on X, Reddit and LinkedIn, to YouTube and to any passage you highlight, so the research for your next piece ends up in one Gemini Notebook.

An example Workspace for a channel, with a Reddit thread just saved to the next episode’s notebook. ## How do writers and creators use Kortex? Writers and creators use Kortex, a Chrome extension for Gemini Notebook (formerly NotebookLM), to save posts from X, Reddit and LinkedIn, YouTube videos and highlighted passages into a notebook per project as they browse. Then they ask that notebook for angles, outlines and briefs grounded in what they saved, and export the research as Markdown to wherever they draft. ### Workflows on this page 1.

[Export research next to your draft](#to-the-draft) ## Where research gets lost The idea arrives while you’re scrolling. Kortex makes saving it a single click. - **The thread that sparked the idea is gone from your feed by tonight.** X threads, Reddit posts with their top comments and LinkedIn posts with the author go to a notebook in one click, from the post itself. - **Researching a video means watching twenty others first.** Send a channel’s uploads, a playlist or a YouTube search to a notebook, then ask it what they cover and what they skip. - **The best lines are scattered across articles, newsletters and PDFs.** Highlight the line and right-click. It becomes a source with the page link and the date, ready to quote and credit. - **Your hook and outline prompts live in a notes app.** Keep them in your Prompts library and type a `;shortcut` in ChatGPT, Claude or Gemini to drop one in. ⌘⇧P opens your prompts on any page. - **The draft lives in Notion or Obsidian. The research doesn’t.** Download a notebook’s sources and notes as Markdown, or one ZIP, and put them next to the draft. ## Four ways to work Four routines that fit around the work you already do. ### Save posts and ask questions of them Saved posts and lines you can ask questions of. 1. Make a notebook for each project or show, and one for your swipe file. 2. On X, Reddit or LinkedIn, click the Kortex button on a post to send it. Reddit posts come with their top comments. 3. Highlight a line in any article, right-click and send it. The page link and date come with it, so crediting is easy. 4. Ask the notebook which angles your saved sources cover and which they miss. ### Research a video topic from other videos A briefing on what’s been said, before you write a word. 1. Search YouTube for your topic and send the results, a playlist or a channel’s uploads to a new notebook. 2. Each video becomes its own source. 3. Generate a briefing doc, then ask what the top videos agree on and where they contradict each other. 4. Plan the rest with the [YouTube workflow builder](/tools/youtube-to-notebooklm). ### Draft with your own prompts, in any AI chat Your best prompts, one shortcut away wherever you write. 1. Save your hook, outline and repurposing prompts in the Prompts library, in folders, each with a `;shortcut`. 2. In ChatGPT, Claude or Gemini, type the shortcut in the chat box and the full prompt drops in. 3. When the draft chat is done, send it to the project’s notebook so it sits with the research. 4. Keep the prompts you reuse in your Prompts library. Prompts Library ![The Prompts Library in the Kortex Workspace with 63 prompts, including Explain Like I’m 5, Create an Outline, Meeting Agenda and Identify Knowledge Gaps.](/media/tour/tour-prompts-1200.webp) The real Prompts Library in the Kortex Workspace. ### Export research next to your draft Sources and notes as Markdown, next to the draft. 1. Download the notebook’s sources as Markdown, or as one ZIP. 2. Export the briefing doc and notes from the Studio as Markdown or PDF. 3. Copy a chat as Markdown to paste into your draft. 4. Turning it into a newsletter or a thread? The [research to content planner](/tools/research-to-content) has the prompts. ## What reviewers say about these features Quoted word for word and linked to where they were posted. Reviewers don’t say what they do for a living, so we picked reviews about the features on this page. > “Kortex turns NotebookLM into an actual knowledge base instead of a fancy note dump. Highlighting text from any webpage and sending it straight in feels borderline magical.” [Suhani, on Chrome Web Store](https://chromewebstore.google.com/reviews/75dc6eaf-f296-4002-9b41-af0bc4d24823) ## Prompts, tools and reading ### Prompts to copy - [Summary you can act on](/prompts/summarize) - [Book summary](/prompts/book-summary) ### Free tools - [Research to content](/tools/research-to-content) - [YouTube workflow builder](/tools/youtube-to-notebooklm) - [Audio Overview planner](/tools/notebooklm-podcast-planner) - [Prompt and Studio library](/tools/prompt-library) ### Further reading - [How to Add YouTube Videos to Gemini Notebook](/blog/gemini-notebook-youtube) - [Gemini Notebook to Notion & Obsidian](/blog/gemini-notebook-to-notion-obsidian) - [How to Make a Podcast with Gemini Notebook](/blog/notebooklm-podcast) - [30 Best Gemini Notebook Prompts](/blog/best-notebooklm-prompts) - [Gemini Skills: Reusable Prompts for Gemini Notebook](/blog/gemini-skills-prompt-library) ## What writers and creators ask Something we missed? [Ask us](#contact). ### Which sites does the send button work on? AI chats on ChatGPT, Claude, Gemini, Perplexity, Grok, Kimi, Genspark and OpenEvidence; posts on X, Reddit and LinkedIn; YouTube; and Google Docs. On any other page, highlight the text and right-click to send it. ### Can I save a whole YouTube channel? Yes: a channel’s uploads, a playlist or the results of a search. Each video becomes its own source. Gemini Notebook caps the sources in one notebook, so for big channels pick the videos you need. ### Do my saved prompts work outside Gemini Notebook? Yes. Type a `;shortcut` in the chat box on ChatGPT, Claude, Gemini and the other supported AI sites, or open your prompts on any page with ⌘⇧P (Ctrl+Shift+P on Windows). ### Can Kortex save Instagram or TikTok posts? Not with the send button, which covers X, Reddit and LinkedIn. On other sites, highlight the text you want and right-click to send it. ## Start the swipe file today.
