AI-powered, expert-managed digital marketing
Automated sentries watch each relevant platform account around the clock so issues are surfaced and routed the moment they appear.
Every optimization is presented with the proposed action, the documented justification and the expected impact, so you see the logic before shipping.
Recommendations are grounded in a large corpus of primary-source platform documentation, and each claim links back to the canonical sources it relied on.
SEO, AI-search visibility, conversion rate optimization, paid search and social, plus email and SMS, are handled by a single shared system.

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.
