ShellTerra

What ShellTerra does:

Plan better when you visit places, and share about your community. ShellTerra starts private, a realm for you and your friends, and grows into something neighborhood-scale as more people join.

Traveling:

Plan ahead. Add destinations for friends and family, and chat about the trip before you go.

Build a realm around a trip, drop the places you want to hit, bring in the people coming with you, and talk it all through in one private space. When you get there, timemarks and activities keep a record of where you went and what you did.

Private messaging:

A private space to talk with the people in your realm, built for friends first, not a public feed.

Encrypted information sharing:

Share information securely within a realm. What's shared privately stays private to the members.

Magic words:

Use magic words to join a realm. A simple, invite-based way in that keeps small realms tight-knit.

Timemarks:

Leave timemarks on the places that matter. Every place remembers what you and your realm did there.

Activity planning & sharing:

Plan activities together and share them with your realm; coordinate visits, events, and outings in one place.

Community content:

Add community content to a realm so it builds up over time — the shared record of a place and its people.

Private vs. public:

Realms start private among friends. Once a realm reaches 19 active members, owners can make it public — turning a private circle into a neighborhood presence.
