Neosemantix Inc.
Carta21 turns your prompt text into geopolitical insights: a set of maps of places and events mentioned in your text, a consolidated map with summary annotations, a timeline, and a power index. You can start without an account. Taste tools (what Carta21 is, a canned demo pack, and the Join link) need no login and offer a glimpse of the insights generated. To generate Carta21 insights on real input within Claude, Connect and complete Allow in the browser: • Connector Trial — enter an email and allow. You get five real insights. One trial per email. • Paid — after you join and subscribe on carta21.com, connect again and choose “Use my Carta21 account” with that email and password. Claude then uses the same quota as the website. This connector does not take payment. Subscribe at https://carta21.com/. Claude’s own plan (Free, Pro, Team) is separate from a Carta21 subscription.
