Embedding Index Tuner
Tune a vector index — HNSW graph parameters and quantization — to hit a recall target at the lowest latency and memory, by sweeping settings against a fixed query set instead of trusting defaults. Use when vector search is slow or memory-hungry, when recall dropped after enabling quantization, or when standing up an index and you need defensible parameters.
Postgres Index Strategist
Recommend the right Postgres index for a query or workload — choosing B-Tree vs. GIN vs. BRIN vs. partial/covering/expression, checking for redundant or unused indexes, and verifying the choice against the query plan. Use when a query needs an index, when deciding an index type for jsonb/array/full-text/time-series data, or when auditing an over-indexed table.
