The K-12 learning platform for India & Ghana

Learning, reimagined.

Adaptive, private, never metered — the K-12 learning platform schools switch to.

I run a school

Replace Moodle without losing a term. Selective import, dry-run preview, one-button rollback.

Feature count = shipped capabilities (full + partial) across our public feature register and four independent benchmark audits, last verified 14/08/2026. Nothing on this page is a roadmap item unless marked "Shipping this term".

Four portals, one platform

Everyone gets their own front door

Students, teachers, parents and school leaders each see a portal built for how they actually work — the same live data, read four different ways.

Student

Study without the clutter — and always know exactly where you stand.

Enter portal

Teacher

Author once, differentiate for every learner, and know who needs you today.

Enter portal

Parent

Your child's week at a glance — grades when they're released, alerts when work slips.

Enter portal

Management

Run the school on numbers that explain themselves — no data person required.

The problem

Four things every school quietly puts up with

Content lives everywhere except one place

Worksheets as PDFs on someone's drive, links on WhatsApp, notes on paper. Nobody can find last term's material — including the teacher who made it.

No idea who's actually learning

Logins are not learning. Most platforms can't tell you which child watched, practised and improved — you find out at exam time, when it's too late.

Moodle upkeep eats the school year

Plugins, patches, version upgrades and a server admin the school doesn't have. The tool built to help teaching becomes a second job.

Analytics that need a data person

Raw logs and CSV exports are not answers. If a report needs a specialist to interpret, most schools will — correctly — never open it.

The promise

Zelarium puts the whole teaching year in one place, watches real learning evidence — not logins — and reads it back in plain language a principal, a teacher and a parent can all act on. And it replaces the patchwork without deleting your past: your existing Moodle content imports selectively, with a dry-run preview before anything is written and a one-button rollback after.

What's inside

Seven families. Every claim shipped.

Every bullet below is live in production today. The count on each family is fully-shipped features only, from our feature register and benchmark audits — partial features are not counted.

Learn

A focused, resumable, searchable learning experience — built for a school laptop or a budget Android phone.

Features in this family: 47
  • Distraction-free lesson player with focus mode, keyboard shortcuts and fullscreen
  • Resume exactly where you left off — every lesson remembers your position
  • Searchable synced transcripts — click a line, the video seeks to that moment
  • Timestamped notes and bookmarks, searchable across the whole course
  • Continue-learning card, progress ring, due-this-week and needs-attention rails
  • 9 activity kinds with per-lesson duration and per-module workload estimates
  • Chapter markers, speed control, 10-second skips, watch-percentage completion
  • Course-wide search across activities, readings, transcript moments and your own notes

Adapt

Deterministic, teacher-controlled differentiation — every rule explainable, no black boxes.

Features in this family: 20
  • Score-band release conditions route each learner to easier or harder follow-on work
  • Differentiated assignments — one trigger, up to three score-banded paths: remediation, core, enrichment
  • Mastery-gated progression and prerequisite rules by score or completion
  • Per-student and per-group date overrides — differentiated deadlines without side spreadsheets
  • Teacher-assigned remediation recorded as a governed intervention, not a verbal note
  • Spaced-review nudge surfaces the outcomes each learner should revisit
  • Locked content always says why — every gate shows a human-readable reason

Assess

Native quizzes, rubric grading, competency mastery and verifiable certificates — with an audit trail under every mark.

Features in this family: 33
  • Native quizzes: timed exams, untimed practice, multiple attempts, question banks and randomization
  • Rubric-based grading with resubmission workflows and due/late status
  • Central gradebook with grade-visibility controls and teacher overrides
  • Every grade change is ledgered — who changed what, from what, to what, why, when
  • Competency framework: outcomes mapped to activities, evidence attached, mastery trends over time
  • Certificates auto-issue on completion — publicly verifiable, revocable only with a recorded reason
  • Deadline calendar with late and missed-deadline indicators

Analyze

Answers, not logs. Analytics a teacher and a principal can read without a specialist.

Features in this family: 51
  • Explainable at-risk queue — every flag comes with its structured "why", never a black-box score
  • Real quiz psychometrics: difficulty, discrimination, distractor analysis — with honest blanks when the sample is too small
  • Score distributions, completion grids, engagement funnels and per-person participation drill-downs
  • Time-on-task engine with session reconstruction and a resource heatmap
  • Inactivity dashboards and school-wide daily-actives statistics
  • Weekly school report snapshots with plain-language formulas, archived and downloadable
  • CSV export on every report — your data is never trapped in a chart

Engage

Motivation that traces to real learning — plus the discussions and announcements that hold a class together.

Features in this family: 49
  • Full gamification suite: XP, levels, badges, streaks, weekly goals — on by default, per-school configurable
  • Every award traces to learning evidence — a completion, a mastery check, a graded submission. Never login farming
  • Leaderboards with every safety mode: real-name, nickname or anonymous; opt-in; top-N; class-vs-class
  • Streaks with a weekly grace day — built in, never sold back to the student
  • Course discussions, lesson Q&A and announcements with moderation controls
  • Teacher quick-awards — every manual award carries the teacher's own note
  • Parent digest PDF, optionally password-locked for the family alone

Operate

The everyday machinery of running classes — authoring, rosters, interventions and family communication.

Features in this family: 21
  • Course authoring across 9 activity kinds, with question banks and a rubric builder
  • Release scheduling, access rules and groups/cohorts per class or per learner
  • Class roster with live progress and per-student course summaries
  • One-click interventions: message, assign practice, extend a deadline — each logged with its outcome
  • Parent portal: child progress, missing-work alerts, upcoming deadlines, released grades
  • Principal's school-level completion KPIs and scheduled weekly report snapshots

Trust

Governance a school can defend — auditable, exportable, scanned and permissioned.

Features in this family: 9
  • Append-only audit ledger for logins, grading, authoring and imports — unprunable without cause
  • DPDP-ready data export — per-user and whole-school, in open formats
  • Every upload is virus-scanned before it can ever be served to a child
  • AI usage metering, budget caps and a kill switch — off by default, auditable when on
  • Role- and permission-aware analytics — you only ever see what your role allows
  • Public certificate verification with reasoned, recorded revocation

Counts by source: Learn + Assess + Operate + Trust from the shipped-feature register (139 fully-shipped rows of 220); Adapt from the adaptive-learning benchmark (20 live of 100 committed); Analyze from the analytics benchmark (51 live of 144 inventoried); Engage from the gamification benchmark (42 live of 70) plus 7 shipped discussion features.

For schools

Built to replace Moodle — without disrupting your school year

One platform for content, assessment, analytics and family communication — with a real migration machine instead of a login screen and a prayer.

Moodle Excel gradebooks WhatsApp-only notices Your school on Zelarium
  • Dry-run preview. See exactly what an import would create — courses, users, content — before a single record is written.
  • Selective import. Bring the courses and people you want, leave the clutter behind. Every change is recorded in an import ledger.
  • One-button rollback. An entire import reverses in one action, from its own ledger. Switching in is never a one-way door.

Migration, step by step

1

Connect & preview

Point Zelarium at your Moodle export. The dry-run shows everything it would import — nothing is written yet.

2

Pick what comes across

Choose courses, users and content from a selection tree. The import runs with every change ledgered.

3

Go live — or roll back

Teach from day one. If anything is wrong, one button restores the pre-import state from the ledger.

Four commitments

The promises we can already keep

Not aspirations — each of these is enforced by shipped machinery, today.

AI on your terms

Bring your own key or use ours. Hard budget caps, per-user quotas and a kill switch — off by default. AI never surprises your bill.

Your data stays yours

Self-hosted, exportable in full — per-user and whole-school — and every upload virus-scanned before it is ever served.

Migration is reversible

Dry-run preview, selective import, and a ledgered one-button rollback. Joining Zelarium should never feel like a one-way door.

Every metric is explainable

At-risk flags come with reasons. Statistics show honest blanks when the sample is too small. No black boxes, anywhere.
