Every school has a soul. C3NTR holds it.
Your school is more than a venue. It's a community. C3NTR preserves your values, traditions, and the bond between every teacher and student.
Knowledge grows when it has structure. A clear library guides students through your system, one step at a time, and makes sure nothing is lost between sessions.
Every discipline has a culture. Store your school's philosophy, ethos, and history in a format as enduring as what you teach.
Eighty starter templates across ten disciplines. Import one, shape it to your school, and publish the same afternoon. No training course, no IT project.
A few notes, a photo or a clip, and it reads beautifully without you styling a thing.
Optional polish from your own Claude or ChatGPT key. It stays on your phone.
Tag it once and search reaches every article, term and clip on the device.

Smart import reads headings and turns them into draft articles. You review before anything publishes.
Notion exports, Obsidian notes, Bear, plain .md files. Paste or import.
Open .c3t.md format. Schools can share templates with each other without us in the middle.
Grade-aware content, on-device search and a library your school owns. Here's the short version.
Unlocks when the student is ready. Instructors always see everything.
Keyword and semantic. Nothing leaves the phone.
The library is there in the training hall, with no signal.
Word or Markdown in, draft articles out. You review before publishing.
Your logo, colours and tab names. An app that feels like yours.
Publish once and every student gets a push notification.
Hosted on Google Cloud in London, encrypted in transit, never sold or shared, and AI runs on your students' devices, not our servers.
