Active recall
Bringing an answer to mind — not re-reading — is what actually builds memory. Every quiz and flashcard is designed to make the brain retrieve, not just recognise.
AI-powered · Board-aligned · CBSE, ICSE, IGCSE & IB for schools
Learning that stays. A platform that runs the rest.
Students remember what they learn. Teachers teach from the same place. Schools and institutions run admissions, fees and operations on the same database. One ecosystem — for families, schools and institutions.

The Prepdha ecosystem
One platform. Three powerful solutions.
Learn, teach and manage on a single database — so a student is one record from first enquiry to final exam.
01 · Learn
LMS
Simplified content, Dharani AI, flashcards, spaced revision, labs and mock exams — the part that makes students remember. What families use at home; what schools teach from.
21features
02 · Manage
ERP
Attendance, fees, admissions, timetable, exams, transport, HR, payroll, documents and a plain-English reporting AI — the whole office, in the same app.
21modules
03 · Grow
CRM
Every enquiry tracked from first call to confirmed admission — counsellor workflows, AI voice follow-ups in Indian languages, campaigns, and one-click conversion into the ERP.
15tools
Families use the LMS. Schools run all three. Institutions run all three on their own content, under their own brand.
Why Prepdha
Students forget. Schools juggle.
Prepdha fixes both.
Every learning app answers forgetting with more hours. Every ERP answers chaos with more logins. Prepdha does neither — it makes learning stick, and runs everything around it on one database.
Learning that lasts
Spaced revision and active recall bring topics back before they're forgotten — the science underneath the LMS.
One system, not five
LMS, ERP and CRM on one login and one database. A student is one record from first enquiry to final exam.
AI where it counts
Dharani for students, a plain-English reporting AI for leaders, AI follow-up calls for admissions — built in, not bolted on.
Safe, and yours
Age-appropriate guardrails, DPDP-aligned, no ads — under your school's or institute's own brand.
The science behind Prepdha
We don’t fight forgetting. We design around it.
Over a century of memory research points to the same truth: we forget most of what we learn within days — unless it’s revisited at the right moments. Prepdha is built on that science.
Spaced repetition
Students schedule each topic to come back at widening intervals — just before it'd be forgotten. Prepdha reminds them when the day arrives. Each return strengthens the memory and slows the fade.
Mastery, not coverage
Weak topics are surfaced early and revisited more often, so understanding deepens instead of gaps quietly piling up.
The forgetting curve
Without revision, memory drops sharply — that’s the line you see now. Tap the revision days on and watch recall climb and hold.

Illustrative model based on the forgetting curve from memory research (Ebbinghaus, 1885).
The research behind this
1885
Ebbinghaus first measured the forgetting curve — memory of new material drops sharply, then levels off.
2006
Cepeda et al. synthesised 317 studies — spaced practice reliably beats cramming.
2008
Karpicke & Roediger showed active recall beats re-reading by a wide margin.
2015
Murre & Dros replicated it in PLOS ONE, confirming the curve’s shape holds over a century later.
