Embedding Similarity Calculator
Enter two equal-length numeric vectors to calculate their cosine similarity. This tool performs arithmetic only and does not query models or vector databases.
A QUICK WALKTHROUGH
How to use this tool
- Enter finite numeric values separated by commas, spaces, or line breaks.
- Ensure both vectors have the same length and neither is a zero vector.
- Review the cosine similarity and validation message.
Arithmetic only
The result is dot(a,b) divided by ||a|| × ||b||. It is a mathematical score for the supplied vectors, not a semantic explanation or quality rating.
Input validation
Both vectors must contain finite numbers, have equal lengths, and have non-zero magnitudes. Values stay in this browser.
GOOD TO KNOW
Common questions
Does it create embeddings?
No. Enter the vectors yourself; the calculator does not call a model.
What does the number mean?
It is the cosine of the angle between the two supplied numeric vectors. Its interpretation depends on how those vectors were created.
