Kortex is a Chromium browser extension that extends Google NotebookLM, now called Gemini Notebook. It imports chats from ChatGPT, Gemini, Claude, and Perplexity, saves web highlights and social posts as sources, and exports notebooks to PDF, Markdown, text, or ZIP.

Tier 1 gives 200 stored prompts and 1,000 podcast feed minutes, Tier 2 gives 500 and 2,000, and Tier 3 gives unlimited prompts and 4,000 minutes. All tiers include cloud sync, automation pipelines, and bulk imports. Reviews are split: some buyers love the added workflow, while others report vanishing notebooks, bugs, and slow support.
