Revalk was our first aspirant experiment.
Revalk was a premium study OS for NEET/INI built around doubt-capture and recall. It's been paused for some time. The active aspirant product is now Calvetra — a broader, neutral cross-platform layer. We keep this page as an honest archive rather than deleting the work.
Archive · what it was
Explore → Collect → Master.
A calmer, tablet-first study product: capture confusion, convert it into recall packs, and retest before you forget.
Explore
Browse tiered concept chunks and discover bridge topics that connect PYQ clusters.
Collect
Save what matters into a private Vault, tag it, attach notes and media.
Convert
A saved concept became a compact Walk Pack — cards, a trap note and a short audio recap.
Master
Recall under pressure, repeat fast, retest loops and coverage tracking.
Exam-proximity tiering
Iron → Platinum, by PYQ frequency.
Every concept was tagged by exam proximity using PYQ topic mapping — a relevance rank, not a quality rank.
Safety-first: concept-level only, no paper reconstruction. Privacy posture: minimal retention, user-owned vault.
Why we moved on
Calvetra is the bigger idea.
Revalk sat inside one study loop. Calvetra steps up a level: a neutral layer above every platform — cross-platform coverage, a video-first planner, and verified spaced revision. It carries Revalk's discipline into a product with far more leverage.
Where to go
Aspirants should use Calvetra.
If you're preparing for NEET-PG, INI-CET or FMGE, Calvetra is the active, supported product.
