Why teams pick it
Three things you get on day one
Semantic, not keyword
Vector similarity across 1024-dim embeddings catches paraphrase, synonym, and conceptual overlap — keyword search misses all three.
Benefit 1 of 3Multi-exam corpus
UPSC IAS, BPSC, CDS, CAPF, AILET, CAT, CSIR NET, and growing — search once, see overlapping coverage across exams.
Benefit 2 of 3Topic clustering
Results are grouped by topic so you can see the syllabus shape — five questions on judicial review, twelve on inflation targeting.
Benefit 3 of 3

Cross-prepping for UPSC + BPSC — needs one search that surfaces overlap across both syllabi.
Saves matched questions into a prep board; emails them to themselves on weekends to draft.
