Many of these tools cluster around use cases like Chatbot, Chat, Q&a, and Gpt — the same problem spaces Harpa addresses. Cross-referencing tools that overlap on multiple topics gives a more reliable signal than category alone, because two products in the same category can still serve very different workflows.
Our ranking weighs eight signals: shared category, topic overlap, feature overlap, name and description text similarity (via PostgreSQL's pg_trgm and tsvector), Bayesian-smoothed user ratings, pricing-model match, popularity, and editorial overrides. Scores are then normalized within each tool's own candidate pool so the top match always represents the strongest available alternative.
