How to Use Vector Cosine Similarity & Embedding Comparator

Follow these simple steps to process your files securely in browser memory.

1Step 1 of 3

Paste Vector A & Vector B

Input float array embeddings in comma-separated or JSON array format.

Pro Tip: Both vectors must share identical dimensionality (e.g. 1536 for OpenAI).
2Step 2 of 3

Calculate Cosine & Distance

Computes cosine similarity (-1.0 to +1.0), Euclidean distance, and dot product.

Pro Tip: For normalized vectors, Cosine Similarity equals the Dot Product.
3Step 3 of 3

Analyze Angular Separation

Inspect angular separation in degrees and copy summary metrics.

Pro Tip: Scores > 0.82 typically indicate high semantic relevance in RAG search.
