Turn the publications you follow into your own thought-leadership posts
Bring newsletters, blogs, websites and YouTube channels into one feed, skim summaries and keep your sources organised in one place.
AI scores takeaways inside a single article, video or newsletter (Insights) and detects wider themes that span several publications (Stories).
A saved writing persona and an editable Brand Profile steer the tone of the draft and prioritise stories that match the themes you want to be known for.
Upload your own PDFs, DOCX files and notes, mine them for insights, and convert existing reports or frameworks into new content.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
